Introduction to HAPI MKII

Modular by Design

Hapi, the son of Horus. Born from the most flexible and sonically transparent audio interface and providing the same RAVENNA / AES67 connectivity as its father, Hapi is both the perfect primary interface for smaller systems as well as the ultimate accessory for a system using Horus where control room I/O is required. Hapi was designed to give its users an Audio I/O channels flexibility while offering an unprecedented level of quality in such a small form factor.

Providing as standard; 8 channels of AES- EBU I/O plus 8 ADAT or 2 SPDIF I/O (on TOSLINK) and 2 Network interfaces 2 slots for AD8D/AD8P, DA8/DA8P, MADI or PT64 option cards. Once the Hapi is fully loaded with option cards, it is capable of achieving 88 inputs and 90 outputs @ 1FS There are indeed 2 more output channels than input channels, including the Stereo Headphone Monitoring.

Route Signal Anywhere

Hapi has been designed so that any input can be routed to any number of outputs as required simultaneously. With comprehensive routing pages accessible both locally on the touchscreen and by remote access using a standard web browser, Hapi is the answer to signal flow management in your studio.

Green Built

For environmentally-conscious users, Hapi has been designed meticulously in order to keep power consumption at an incredible minimum. A fully loaded Hapi running all channels of phantom power will only draw about 30W, making it more affordable to run than your kitchen lights.

HAPI MKII Key Features

• Up to 88 inputs and 90 outputs @1FS
• 8x AES/EBU + 8x ADAT or 2x SPDIF (Optical)
• Standard modules support 44.1kHz to 192kHz and Premium up to DXD/DSD256.
• Signal routing from any input to any combination of outputs

  • Headphones DSD volume support (DSD64, DSD128, DSD256)
  • Headphones DSD256 support
• OLED display for local control access

RAVENNA

The Hapi has been designed so that the MADI, AES, SPDIF/ADAT, PT64 and Analog modules can all feed into or take their sources from the network over RAVENNA streams, providing up to 88 channels of I/O @ 1FS over a single CAT5e or CAT6 cable to any other RAVENNA devices on the network.

The RAVENNA connection on the Hapi allows for not only audio, but also control and sync information to flow through as well. Send Timecodes and Wordclock directly to the Hapi unit over the same network as your audio. The RAVENNA port even provides for remote control access to the configuration and entire routing of the unit itself! Support for: LTC/Video Ref/WCK

RAVENNA is a layer 3 IP based protocol. In environments where existing networks are already in place, RAVENNA subnets can slip right into place with no additional outlay. In laymen's terms, this means that you can connect your Hapi to a properly configured network exactly as you would your PC or Mac, with no additional technology required.

RAVENNA is a “mission critical” protocol, meaning that is has been designed to ensure immensely low jitter rates and latencies (sub-millisecond) and ensures that every single sample gets to where it needs to go without fail. Hapi MKII provides a secondary (RJ45), redundant RAVENNA connection for uninterrupted use, even when a network connection fails, it can also be used in switch mode.

Line Output Level calibration

On the DA8 and DA8P cards, the output level setting for all channels is done via software through the option "max output level" in each DA's setting page, allowing either +24 dBu or 18 dBu max level.

For a more precise trimming of the output level, the output attenuation can be set on the same page

The Hapi software Output Attenuation range is from -60dB to 0dB

How to connect the symmetrical line out to an unbalanced input

Never attempt to short pin 3 (or pin 2) to Ground on Hapi DA's output, since the Hapi Line Out driving circuitry is symmetrical but not floating.

Furthermore, as Unbalanced Inputs are traditionally more sensitive than Balanced Inputs, the -6dB Analog level achieved by using only one of the Hapi symmetrical outputs, will offer better signal level adaptation with less risks of overdriving the Unbalanced Inputs connected to the Hapi.

Line Output Level calibration

The DA8 and DA8P modules feature both hardware level settings and a software fine adjustment to align the Analog Output levels to whatever local/organization operational levels are mandated.

On DA8/DA8P cards from run 7 upwards, the hardware level setting is done via software through the option "max output level" in each DA's setting page, allowing either +24 dBu or 18 dBu max level.

On DA8/DA8P cards prior to run 7 the hardware level setting is in the form of 4 DIP switches per output channel

The Hardware settings will usually be set only once, at product installation, and only if the desired Operating Line Level differs from the default ex-factory settings of +18 dBu for 0 dBFS.

Procedure for Hardware alignment (for DA8 prior to run 7):

1. Shut down your Horus and make sure that the Horus back panel Power is also switched OFF.
2. Unscrew all DA8 modules that need adjustment.
3. Pull gently out (5-7 cm is enough) to access the DIP Switches. There is one block of 4 dip switches per channel. Channel 1 is labeled S1, channel 8 is labeled S8.

1. Set the DIP Switches as per the table legend printed on the DA8 module card (run 6 and below)

		Output Level (dBu)
		+24	+18	+15	+12
Switch S1 to S8	1			ON	ON
	2		ON		ON
	3		ON		ON
	4			ON	ON

Output Level calibration Example:

Assuming your operating Level is 21 dBu for 0 dBFS (typical of French Radio Broadcasters), you should set the DIP Switches all OFF (DIP Switch positioned to the left, with respect to the picture below) to set maximum Output Level to +24 dBu (since there is no 21 dBu hardware setting)

Once this is set and the DA modules are screwed back in place. Power up the Horus and go to the Horus Setup Page>Module, select each D/A module for software calibration.

In this example case set the software attenuation to -3 dB (see image below), so the overall result ends up at 21 dBu for a Full Scale signal

The Hapi software Output Attenuation range is from -12dB to 0dB

How to connect the symmetrical line out to an unbalanced input

Never attempt to short pin 3 (or pin 2) to Ground on Horus DA's output, since the Horus Line Out driving circuitry is symmetrical but not floating.

Furthermore, as Unbalanced Inputs are traditionally more sensitive than Balanced Inputs, the -6dB Analog level achieved by using only one of the Horus symmetrical outputs, will offer better signal level adaptation with less risks of overdriving the Unbalanced Inputs connected to the Horus.

IOM-H-PT64

This module allows you to connect your Hapi directly to a Pro Tools HD or Pro Tools HDX system through its two Digilink Mini connectors. You can plug up to two modules in a device, meaning you can record up to 128 Channels at a time.

IOM-H-PT64 Key Features

• Up to 64 Channels @48kHz per module (32 ch. @ 96kHz, 16 ch. @192kHz)
• Up to two IOM-H-PT64 modules in one Horus/Hapi
  • Automatic Delay Compensation
• Three hardware emulation modes (Digidesign 192I/O, HDIO and HDMADI)
• Two Digilink mini connectors

Ports usage

There are two connectors on the IOM-H-PT64 module called Port 1 and Port 2.

Working at 44.1/48kHz, both Ports are enabled. Channels I/O 1-32 are carried through Port 1 and channels I/O 33-64 through Port 2. If only 32 channels are needed, it is possible to use only Port 1 or only one of Port 1 or Port 2 in HD I/O or 192 I/O modes only.

With a Sample Rate of 88.2/96kHz, only Port 1 is enabled. All 32 I/O channels will be carried through this Port.

If the Sample Rate is set to 176.4/192kHz, then all 16 I/O channels will be carried through Port 1 as well.

Port 1 of your IOM-H-PT64 should always be connected to Port 1 on the AVID interface and Port 2 should always be connected to Port 2 even if just one Port is used.

Note: Cables of same length must be used when both ports are connected.

Note: When using 2 IOM-H-PT64 cards in a single device in order to benefit from 64 channels at 88k2/96k, you can connect Port 1 of the first card to HDX/HD Native Port1 and Port 1 of the second card to HDX/HD Native Port2.

Synchronization and Word Clock

When properly configured, Hapi is able to automatically change its internal clock to match a Pro Tools project's Sample Rate. The proper IOM-H-PT64 module must be selected in the I/O & Sync menu (PT 1 or PT 2 if module is in Slot 1 or 2). The Auto-follow option must be enabled in Setup -> Format menu, and Hapi will change its Internal Sample Rate automatically.

In Pro Tools, the Clock source should be set to Internal for the device emulated by the IOM-H-PT64 module (HD MADI in the following example).

Sampling Rate mismatch protection

Audio from Pro Tools to Horus and from Horus to Pro Tools is muted when the Sampling Rate asked by PT is not met by Horus to avoid recording when Sampling Rates mismatch.

Enable the Auto-follow SR option and Synchronize on PT module to avoid any SR mismatch.

Setups with multiple devices

If your setup is made of several Pro Tools Hardware interfaces that need to be synchronized, our recommendation is to select Internal Clock Source of your IOM-H-PT64 module as the Master Clock. The other devices present in the setup can be synchronized several different ways.

If two Hapi interfaces are used in a setup, they can be synchronized through the Word Clock connectors. To send the actual Sample Rate, the Follow SR option in Setup -> Format must be enabled.

The next setup is using Hapi as the Master clock for all devices. In this case, the Clock Source must be set to the other device's Word Clock. The Follow SR option in Setup -> Format must be enabled.

In the following setup, an external Master Clock is used for all devices. In this case, the external Master Clock controls the Hapi Sample Rate. Hence, the external Master Clock must be set accordingly to the Pro Tools project Sample Rate.

IOM-H-PT64 block diagram

Delay compensation

Input and Output delay are strongly dependent on the Hardware. This implies that if one records a single source with two different devices at the same time, one will get two slightly out-of-phase tracks. This is explained by the fact that every device has its own circuitry and different components.

To minimize this issue, Pro Tools implemented an Auto Delay Compensation feature which will automatically shift the recording depending on the Hardware used.

The IOM-H-PT64 module was made to emulate three different Digidesign interfaces and match every interface's actual input/output latency (within a margin of maximum 3 samples). This chart shows what latency to expect for different setups. Analog/Digital modules latencies are already included in these measures.

Emulation Mode		Routing	44k1/48k	88k2/96k	176k4/192k
None	Input	-	2* smpl.	2* smpl.	2* smpl.
	Output	-	2* smpl.	2* smpl.	2* smpl.
192IO	Input	From AD8D	65 smpl.	65 smpl.	65 smpl.
	Output	To DA8	24 smpl.	14 smpl.	15 smpl.
HDIO	Input	From AD8D	16 smpl.	12 smpl.	11 smpl.
	Output	To DA8	56 smpl.	21 smpl.	21 smpl.
HD MADI	Input	From MADI	6 smpl.	6 smpl.	7 smpl.
	Output	To MADI	5 smpl.	5 smpl.	7 smpl.

* Added to the other modules used

For the delay compensation to be working, it must be enabled in the ProTools software (Options -> Delay Compensation).

Emulation Mode

Configures which Digidesign interface the IOM-H-PT64 module will emulate in Pro Tools. This option does not affect the Hapi routing or preamps, it will just set the Input/Output Delays as seen above. When set to None, Pro Tools will see the module as an HD MADI, but Hapi will use the minimum latency. Therefore, Delay Compensation will not be accurate on Pro Tools in this mode.

Error AAE -6116

When Hapi is configured to follow the Sample Rate asked by Pro Tools, an AAE -6116 error might happen when opening a project with a new Sample Rate. If it happens, click OK to close the error information. Then, when trying to play the file, the error might show again. After clicking OK, the error should not appear again.

If this issue is too frequent, a way to avoid it is to disable the Auto-Follow option in Setup -> Formats and change the Sample Rate on Hapi by hand. This should reduce the probability of getting such an error.

IOM-HAPI-MADM/MADS

The MADI optional Module card (MADM - Multimode / MADS – Single mode) provides a channel count of 64 inputs and 64 outputs @1FS

IOM-HAPI-MADM/MADS Features

• MADI Optical and Coaxial inputs and outputs
• 64 discrete channels of digital input and output (extended mode) at 1FS
• Up to 384 kHz sampling rate
• 24-bit resolution
  • Fully compliant MADI (AES 10-1991)
• 2 BNC and 1 SC connectors (Multimode or single mode)

Single mode fibers have a lower power loss characteristic than multimode which means that it supports longer runs but single mode fibers are more expensive. The multimode version (IOM-HAPI-MADM) is the most widely used optical MADI connection, but for fiber lengths of more than 600m. Merging Technologies recommends to use the single mode version (IOM-HAPI-MADS).

Connecting the MADI cable

The MADI port (optional MADI Module) can be connected using either Optical or coaxial cabling.

When using Optical cabling, first ensure that you have a clean work area, as dust and debris can affect the connection if any obstruction is present. Remove the cap on both the cable and the port and slowly / firmly push the cable into the receiving port on the Hapi unit until it clicks into place. The MADI optical connector is available in Multimode or Single mode versions. The Hapi is delivered with Multimode connectors unless specified at ordering.

For Multimode MADI i/o Merging recommends the use of the OM1 or OM2 Category, with specifications of 62.5/125 um or 50/125 um. OM3 and OM4 specifications are also supported since those are improved versions of OM2. The wavelength should be 1300 nm.

When Using a Coaxial connector. Slowly bring the Male cable up to the female port, ensuring that the pin in the centre of the male cable lines up with the receptacle in the female port. Push the connector firmly into place and twist the sleeve clockwise until it clicks into its locked position. Maximum recommended cable length is 100 meters

Connecting the Wordclock input/output

The Wordclock connections on the rear of the Hapi unit are coaxial BNC's. To connect a Wordclock source from an external device slowly bring the Male cable up to the female port, ensuring that the pin in the centre of the male cable lines up with the receptacle in the female port. Push the connector firmly into place and twist the sleeve clockwise until it clicks into its locked position.

Connecting the Sync Cable

The Sync Cable (optional with each Hapi unit) is a DB15 cable that connects to the "SYNC" port on the rear of the Hapi unit. The SYNC cable provides connectivity for LTC and Video Reference Input and Output for the Hapi unit. To attach this cable to the Hapi unit, align the male connector with the female DSUB port on the module. Then, with slight pressure, guide the connector into place. Once the cable has been pushed into place, fasten the mounting screws on either side finger-tight.

Note: The Hapi provides Video Reference I/O Synchronization, but is not a Video reference Generator.

Sync breakout cable pin-out

Connecting the RAVENNA Ethernet cables

The RAVENNA ports (Primary and Secondary) are RJ45 female receptacles. Simply line up the RJ45 cable with the slot on the rear of the Hapi unit and slide it into place until it clicks into its locked position.

(Category 5E or 6)

Note: Use the primary (PRI) port. Secondary port behavior depends on the ST2022-7 mode, set in the Hapi Advanced pages (default mode: network switch mode). See Network menu – Network operations modes for details.

HAPI MKII Key Features

Networking

The Merging Hapi MKII fully supports (2) RJ45 connectors, that can be configured in two different modes, from the RAVENNA Advanced Pages.

1) ST2022-7 mode for network redundancy (Seamless Protection Switching)
2) Network Switch mode, allowing the daisy-chaining of one additional network device without the need for an external network switch.

Modular analog interfacing

Hapi allows the user to choose between Analog inputs and Analog outputs and MADI I/O required for each unit. Hapi provides a total of 2 universal I/O slots which can accept a combination of Mic/Line modules and or Line output cards and or a MADI module. Configure Hapi with any combination. For instance, in a studio environment, 8 A/D (1X IOC-AD8/P) and 8 D/A (IOC-AD8/P) will allow for 8 inputs from the live room and 8 outputs to feed studio monitoring and foldback to the artist.

Modular Device connectivity

Any of the modules listed below (A/D, D/A, MADI, AES, ADAT/SPDIF, RAVENNA) can be interconnected in any way the user chooses. Simple and easy routing pages enable the user to source signal from any module, and send it to any other combination of modules. An A/D Module could feed 8 Channels of AES Outputs. At the same time, it could feed to 8 MADI channels, or even the RAVENNA stream as well. This is the function that allows the user operate with the Hapi in either a standalone (Analog to MADI/AES AD/DA) or in RAVENNA Mode, which connects the audio to a RAVENNA network (described below).

With such a wealth of different outputs, it made sense to apply a “route to” instead of a “route from” philosophy in the way Hapi presents its routing pages. After an initial learning period, you will understand that this is a much more efficient way to present so many routing options in an easy to unfold process. So always ask yourself first which output is being considered and then decide what input signal will feed that output and you will be offered all logical and valid choices at every step. It also made sense to limit the granularity of routing options to blocks of 8 channels, as a good compromise between flexibility and complexity.

AD8 / AD8P Remote controlled Mic/Line A/D module

The AD8 (works up to 192 kHz) and the AD8P (works up to DXD/DSD256) are remote controllable, extremely high-quality Microphone pre-amplifiers with a switch on each channel to route the signal through dedicated line level circuitry instead. The remote control is achieved over Ethernet, via the RAVENNA Port at the back of the chassis. With all standard analogue controls also available via remote (Phantom power on a “per channel” basis, polarity invert, HPF) and a Gain stage reaching from -10dB all the way up to +60dB, these modules are not only easy to use, but completely transparent to listen to as well.

DA8 / DA8P Safety Conscious Analogue Line output Modules

The DA8 (works at sample rates up to 192 kHz) and DA8P (works at sample rates up to DSD) are specifically designed with the user's speakers in mind. Incorporating analogue mute circuitry, the DA8/P modules provide protection against spurious transients that may occur during Sample rate changes and power cycling "clicks" and "pops" which can damage not only speakers, but also the listener's ears. When you add to that a noise floor of less than -125dB, these are the ultimate analog outputs for any monitoring system.

ADA8 Remote controlled Mic/Line A/D module with transparent Analog output

The ADA8 v1, ADA8S v2 (work at sample rates up to 192 kHz) and the ADA8P v2 (works at sample rates up to DSD) are combining high quality Microphone pre-amplifiers and analog output module.

HD Link with Pro Tools HD

The PT Module allows the Horus to communicate with a Pro Tools HD card. With two modules in one interface, up to 128 channels can be recorded simultaneously.

DC power supply options

Your Hapi interface can be fitted with a DC power supply input, this can be used to battery power the device or as a secondary power input. The maximum power requirement is 30W thus the supplied current must be of 2.5A if powered with 12V.

The DC power supply option can be used in two way

1- Battery power: The Hapi can be operated from battery, or any external DC adapter provided the voltage is between 10V and 14V.
2- Redundant power supply: The Hapi can be operated in a redundant way when using the standard AC power inlet and an external 12V DC adapter connected to the DC input of Hapi, in this configuration either power input can fail or be removed without creating any disruption in the device's operation.

MADI (Module)

A MADI module is available and can be fitted in one of the Hapi slots. It provides users with up to 64 channels of MADI I/O for use with the system. The signal sent to the MADI Outputs are configurable in blocks of 8 channels and can be sourced from any other module in the Hapi.

Note: Only one MADI module can be fitted per Hapi, please refer to the MADI module section above.

AES-EBU

1 x D-SUB25 connectors providing 8 channels (4 AES pairs) of AES-EBU I/O are Included as standard. The AES-EBU signal is transmitted as single wire at all supported sampling rates.

ADAT/SPDIF

8 ADAT I/O or 2 SPDIF I/O (on TOSLINK) are Included as standard. This module is supported up to 4FS (192 kHz)>.

Note: It is recommended to use 3 Meters and less cable length for proper transparency

PT64

64 Channels of Pro Tools HD™ support on Digilink mini connector, from 44.1 to 192 kHz sample rates

Signal routing paradigm

Hapi is quite possibly the most flexible audio interface ever designed. Users can literally route any input signal to any output module. Better yet, it can route any input signal to any combination of output modules. Routable in blocks of 8 channels, a user can send 8 Mic Inputs to 8 AES outputs. At the same time these 8 mic inputs can also be sent via the MADI outputs and included in the RAVENNA stream.

RAVENNA IP Audio

Using RAVENNA IP audio, Hapi can connect to a standard network, using off the shelf switches and other IT technology to become a node on a LAN. From that point, any other RAVENNA node can receive information from and deliver information to, any combination of RAVENNA devices on the network. It is a revolution in Audio technology and will soon mean the end to costly audio routers and matrices and allow any facility an immense amount of flexibility. From Broadcast and TV/Film post-production, to music, live events, theatres, cruise ships and many more applications, the RAVENNA Enabled Hapi interface will reinvent how systems come together.

The Hapi MKII with its dual network interface provides supports for two different modes of operations.

■ ST2022-7 Seamless Protection Switching. For full network redundancy.

■ Network Switch mode, allowing the daisy changing of one extra network interface connected directly to one of the Hapi MKII RJ45 port.

Notice: We do not support multiple daisy chained devices from the Hapi second ethernet port in switch port. A properly configured Network switch is recommended in order to daisy chain more than one additional hardware audio interface.

Hapi MKII is NMOS compliant

■ NMOS IS-04 (Discovery & Registration)

■ NMOS IS-05 (Device Connection Management)

Synchronization

Audio is not the only information that can pass down the RAVENNA connection. Hapi is also able to send sync (LTC) down the same wire to and from the Hapi unit. For more details refer to the RAVENNA network guide available on www.merging.com

Installing an additional Hapi I/O Module

Installing additional Hapi I/O Cards (AD8/AD8P/AD8D/AD8DP/ADA8 or DA8/DA8P)

Before you start

- Place the Hapi unit on a hard, dry surface or mount it onto a 19" rack and leave plenty of room for air convection.

- In order to meet the EMC requirements of directives 89/336/EEC and 93/68/EEC, and in order to obtain the high performance possible for the Hapi unit, you must use correctly shielded cables of good quality for all external connections when installing the Hapi unit. For the power connection, a normal unshielded power cable with a proper ground can be used.

- Make sure that your sound system is at a safe volume level.

Hardware Installation

This section will take you through installation of your Hapi unit. We will describe how to mount the I/O modules and the power, audio and digital cable connections that can be accessed on the rear panel.

*PLEASE ENSURE THAT YOUR HAPI UNIT IS SWITCHED OFF BEFORE ATTEMPTING TO CONNECT ANY CABLES TO THE UNIT.*

If you need to mount an I/O module at a later stage, the following procedure is used.

1. Place the shutdown Hapi unit on a dry steady horizontal surface. Remove all cables (including the power cable).

2. On the back of the Hapi unit there are 2 slots for mounting the Analog I/O cards or a MADI card.

3. To remove blind plates from I/O module slots, remove the 2 screws on either side of the plate. Use a Phillips (cruciform) screwdriver tool size 2

4. Only remove the number of blind plates necessary to fit the I/O module(s). If only one I/O slot is installed, remove only 1 blind plate. If 2 I/O slots are installed, remove 2 blind plates.

5. It is very important to insert the I/O card horizontally and carefully into the Hapi unit. There are 6 set of guides inside the Hapi unit to guide the I/O cards correctly into place. Do not use force in any way to insert the I/O card. This may damage the card. Slide card slowly as picture below shows.

1. When the cover plate of the I/O card covers the hole created by removing the blind plate, the 2 screws from the blind plate are mounted in the sides of the I/O card. Tighten the screws carefully and be careful not to damage the threads.

2. After inserting the I/O module, the Hapi unit might need to be initialized. If this is the case, please follow the instructions received with the I/O module.

Installing a Hapi MADI Module (MADM or MADS are optional)

Before you get started

2. Slide the MADI extension board carefully so that the back panel of the module touches the Hapi back panel.

3. Align the MADI Module over the 2 spacers and screw the MADI module using the 2x M3 screws.

4. Connect the ribbon cable from the MADI module to the J7 connector on the Main Hapi board. The connector is on the right on the Ethernet 2 and the closet to the MADI module.

1. Fix the module to the Hapi rear panel using the two M2 screws

2. Replace any modules that were removed earlier to provide access

3. Close the Hapi top panel cover and replace the fixing screws

4. Power the Hapi back on and the MADI module will be recognized

Assembling the Rack Mount ears

Hapi is delivered with two rack mount ears for easy installation into a 19" rack. The ears can be mounted either on the front or the rear of the device.

Installing the rack mount ears on the front panel

1. Turn off and unplug your Hapi
2. Unscrew the eight (8) M3x5 screws located on the side of the device (4 screws per side)
3. Place the rack mount ears on the side of Hapi, as shown in the pictures below

1. Fix the ears with the four (4) M3x8 screws delivered with the ears

Installing the rack mount ears on the rear panel

1. Turn off and unplug your Hapi
2. Place the rack mount ears on the side of Hapi, as shown in the pictures below

1. Fix the ears with the four (4) M3x8 screws delivered with the ears

Hapi recommended placement in Rack

Due to confined space in a rack furniture, adequate spacing (and ordering) between multiple Hapi or Horus units will play a significant role on the units temperature. Although Merging has spent considerable time in optimizing the Hapi power consumption in every aspect possible, the units are still drawing an average of 30W. The dissipation of the related heat produced by this consumption is therefore highly dependent on the airflow and natural air convection around those units.

With highly loaded Horus units (more than 3 I/O Analog modules per unit) or Hapi units (2 I/O Analog modules per unit), Merging recommends a free space of 1U above each unit to ensure adequate cooling of the devices, if no other heating elements are present.

Detailed steps on how to install the NET-MSC-GBEX1 PCIe card in your PC.

1. Power down your PC and switch it off at the wall. Remove the screws holding the top or side of the case on and carefully slide off the panel.

1. Wearing an anti-static wristband is desirable whenever working with sensitive electrical equipment. Keeping one hand on a metal part of the case will have the same effect, though you may need both hands when installing certain items of hardware.

2. Locate an empty PCIe slot and remove the metal backing plate by removing the screw holding it in place and carefully sliding it up and out. In some cases, there are no backing plates and you will need to remove a length of metal instead. Do this using a flat-blade screwdriver and/or pliers, taking care to avoid any sharp edges left behind.

3. Next, remove the NET-MSC-GBEX1 card from its envelope bag and line it up with the vacant PCIe slot as shown below.

1. Push down gently at first, ensuring you have the pins lined up correctly with the slot, and then apply more force to slot the card home fully.
2. Use the screw which held the backing plate in place to secure the card and check that the card sits properly.

Finally, replace the case cover(s) and plug your machine back in.

1. At "First Power Up" Windows will discover the Merging Ethernet PCIe card

HAPI MK II - Power ON

Connecting the Power Cable

The Hapi unit runs on 100-240V, 50-60 Hz AC voltage. Excessive voltages can seriously damage the Hapi unit, so make sure that your AC power matches the voltage of your Hapi unit. When you connect the power, use the cable you received with your Hapi unit and plug it into a grounded outlet.

For safety and EMC reasons, and to prevent audio hum, the system must be properly grounded. If your power source does not have a standard three-prong socket, the system must be grounded in another appropriate manner.

As an option Hapi can also be powered from a DC power source (10-14V), contact your local reseller about this option.

Hapi DC power input

Hapi can be delivered with a DC input capability, when this option is ordered a 4 pins connector (HR10A-7R-4S) is installed left to the AC power connector. The mating part which is also delivered is a Hirose HR10-7P-4P.

The pinout of this connector is:

• Pin 1: GND
• Pin 4: 12V
• Pins 2 and 3: not connected

The DC power input accepts voltages from 10V to 14V for a maximum power consumption of 30W.

As an option, Merging does also provide an external AC/DC 30W converter with the appropriate counter-part connector already mounted. Its product code is PSU-AC/DC-30W.

Hapi power up mode selection

The Hapi unit has been designed to have two power up modes selectable with a jumper on the backplane of Hapi:

- Normal operation: Requires to press on the power button to turn ON Hapi, pressing for more than 5 seconds on the same button will shut down Hapi

- Always ON operation: As soon as power inlet cable is plugged in the Hapi will power ON, pressing on the power button to either turn it on of off will have no effect

The selection of the mode can be done using jumper J13 on the backplane of Hapi.

Jumper J13 pinout:

- 1-2: normal operation

- 2-3: always ON operation

The default ex-factory setting is normal mode

Turn ON your Hapi

1. Press the Hapi Front Panel Power Button

Note: Pressing small triangle will display the Home Page on the Hapi OLED.

Warning: The Hapi MkII firmware update differs from the Hapi 1 generation, since the update can be performed without a Maintenance mode start up. Refer to the MkII Firmware update section for details

1. The Hapi front panel button will turn on. If the panel button light isn't steady but appears to flicker, this may indicate a fault condition and requires immediate shut down.

2. Wait until the Hapi is fully started and displaying the Main Home screen.

This is the screen which you will see after the Hapi completes its boot sequence. From here you can navigate to all the other menus for the setup and use of Hapi. If at any time you want to return to the Home Screen, you can press and hold the Main Rotary Control button for a second in order to return to the Home Screen. The screen also has access to the 8 main sections of the Hapi menu: Volume, Meters, I/O, PreAmp, Setup, Presets, Errors and Exit.

Pressing only the Home Page small pyramid button will bring the Hapi home page, this is applicable if no selection is active on the OLED

Volume Menu

The Volume menu is where the user can determine the analog output module which will be controlled by the Hapi Rotary Control. It will also display the output meters of the selected module.

Pressing the Hapi Rotary Control button allows user to select the which analog Module will be volume controllable

If you have multiple DA and would like to have both of them controlled by the Volume button simply select the DA1 + DA2 entry

Meters Menu

The Meters menu is where the user can view the metering of the Hapi available Input or Output modules.

A/D Meters Sub-Menu (Meters)

The A/D meters page displays a VU meter for each A/D Input available. If you have 1 x A/D module you will see 8 VU meters and with 2 x A/D modules you will see 16 VU meters, one for each physical input.

D/A Meters Sub-Menu (Meters)

The D/A meters page will display a VU meter for each D/A output available. If you have 1 x D/A module you will see 8 VU meters, if you have 2 x D/A modules you will see 16 VU meters, so one for each physical output.

Input Levels Sub-Menu (Meters)

The Input Meters page will display the input metering of the modules present in the Hapi. A metering view of one Led per input channel is represented in this page.

The LEDs indicate the inputs levels of the AD1 inputs 1 to 8

Note: You can reset a module Peak by pressing the Rotary Control. In the example above pressing A/D 1(8ch) will reset the peak displayed on the input 1. This led view ledged also applies to the DA view.

Output Levels Sub-Menu (Meters)

The Output Meters page will display the Output metering of the modules present in the Hapi. A metering view of one Led per output channel is represented in this page.

Meters Settings Menu

Hot: Sets the level above which the meter display will be red. If set to 0dB this will

mean clipping. Range -2dBFS to 0dBFS (PCM)

-2dB to 6dB SACD (DXD/DSD). Reminder: DSD users benefit from a +6dB

headroom in DSD with distortion starting slightly and progressively from

+3.1dB upwards and clipping once reaching +6dB SACD

Alignment: Sets metering level alignment range (yellow leds). Range -24dBFS to 0dB

Decay integration time: Sets the rate at which the level meter display decays after the level falls below the most recent Peak.

Peak Hold: If ON it will keep the red Peak Hold Overload in display

I/O Menu & Sync Sub-Menu (I/O)

The IO and Synchronization menu is where the user can select the source of the Hapi reference clock. It is essential that these settings are configured correctly in order to ensure a clean audio signal through the Hapi unit.

Reference Source Choose the desired sync source by selecting a Reference source.

Available Reference Sources are: RAVENNA, WordClock, MADI, AES or SPDIF

Reference navigation Selecting a Reference with multiple choices (such as Sync or AES) will enable the source navigation. The navigation is performed from top to bottom and will cycle through in this order at each consecutive press. The selection of another Reference Source will re-select the top entry in the list by default.

PTP Clock The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. Also known as IEEE 1588, it is a protocol designed to synchronize real-time clocks in the nodes of a distributed system that communicates using a network. RAVENNA is based on and uses

V2 of this IEEE standardized protocol. PTP Clocks allow for time resolution to the Nanosecond.

Master indicates that the current Hapi is the PTP Master

Slave: The Hapi is slave to another PTP Master

The Hapi will always try to be the PTP Master. If multiple Hapi' or Horus' are used in a network environment, the Hapi set in this order will have the PTP Master priority, using the Best Master Clock Algorithm (BMCA):

1. Video sync
2. Word Clock
3. AES
4. ADAT/SPDIF
5. MADI
6. PT64

7. Internal

8. RAVENNA (always slave unless there is no PTP master available)

Note: When two or more Hapi are connected together through an Ethernet network, one of them will always be automatically selected as master, the other Hapi' will be forced into slave state and therefore will not be synchronized to wordclock or audio input. However, this is not a problem since all Hapi' will be synchronized.

Status: LTC IN: Corresponds to the incoming LTC frame rate

Hapi PTP status: MASTER or SLAVE

Video Format Detected:

Supported Formats:

PAL - NTSC

720p23.98-720p24-720p25-720p29.97-720p30

PTP Master note: The GMID (Grand Master ID) is available from Web Access page under IO & Sync, and in the Advanced pages – PTP tab.

Refs Sub-Menu (I/O)

This Sub Page menu is where you can view the Deviation and Jitter of the External Reference, as measured by the Hapi synchronization circuitry.

Frequency: The long-term measured Frequency (in Hz) and deviation in ppm (parts per million) between the signal the unit is locked on to and the internal reference.

Delta: The short-term (instantaneous) time offset between the reference signal and the internal (considered as ideal) reference, measured in nanoseconds (ns). In other words, the delta indicator over a RAVENNA network will report the delta in ns between the master and the slave.

Timecode Sub-Menu (I/O)

IN Timecode: Will display the current incoming LTC/Timecode

OUT Timecode: Will display outcoming LTC/Timecode

Frame Rate: The current LTC/Timecode Frame Rate is indicated next to the Timecode IN & OUT display

From: Indicates the Timecode provider (in example above the Pyramid DAW)

Timecode Level: Shows the current LTC output level in dBu. The selector offers a choice of output level from -18dBu to +9dBu in 3dBu increments, or can be switched off

Mute on Stop: If OFF the LTC output will not be active (default) If ON the LTC output is generated constantly

Status Sub-Menu (I/O)

Lists the status of each Module Channel count (I/O) and each module Mode (Example: PCM or DSD modes)

48k	M	Status
AES	(8ch)	PCM
A/D 1	(8ch)	PCM
D/A 2	(8ch)	PCM
MADI	(64ch)	PCM
Monitor	(2ch)	PCM
Loopback	(8ch)	PCM
SPDIF	(2ch)	PCM

PreAmp Menu

The PREAMP (A/D) menu becomes active if you have 1 or more AD8(P) modules installed in the Hapi unit, giving full access to the Input controls. Please see below for a description of the buttons available.

All Active: Will select all 8 input channels for function and level grouping

Inactive: Adjustments to the input settings and level affect only the selected channel only

Note the All button will group all inputs of the same type (Mic or Line)

Gain slider The Rotary Control will give the user control over the Gain level with

increments/decrements in 0.5 dB steps

The Gain range goes from 0 dB to +66.0 dB from left to right

In Mic mode (M): Sets the Mic Preamplifier's Gain

In Line mode (L): Sets the Line Input Sensitivity

A value of 0dB corresponds to an input sensitivity of +24dBu for 0dBFS. This corresponds to a calibration level of +4dBu for -20dBFS.

A value of +20.0 dB corresponds to an input sensitivity of +4dBu for 0dBFS A value of +66.0 dB corresponds to an input sensitivity of -42.0dBu for 0dBFS

Example: Assuming you want to interconnect to an analog console and your standard studio alignment level is +4dBu for -18dBFS. In this case set the gain slider to +2dB. Similarly, on the DA analog output side, set the attenuation to -2dB, refer to section Line Output Level calibration on page 22, provided the max output level is set to +24dBu.

Mic (M) or Line (L) Switches the Input from the Mic-Pre amplifier to the Line level circuitry. The

button will show the current input signal path it is set for (Mic or Line).

The Line input sensitivity can be adjusted by setting the line gain for each input of the AD module.

Line Fader of 0 dB, means 0 dBFS for +24 dBu Analog signal level present at the Line input

Line Fader of +6 dB, means 0 dBFS for +18 dBu Analog signal level present at the Line input

Line Fader of +20 dB, means 0 dBFS for +4 dBu Analog signal level present at the Line input

Line Fader of + 66 dB, means 0 dBFS for -42 dBu Analog signal level present at the Line input

Note #1: the MIC and Line inputs are stored as independent parameters, meaning that switching from Mic to Line and vice versa will load its own gain (sensitivity) value

Note #2: The Premium AD converters have been designed in order to be able to benefit from the +3.1 dB SA-CD headroom offered by DSD, as per the scarlet book standard. The gain range goes from +0dB to +66dB in both PCM and DSD mode. In DSD mode it is possible to set a gain of up to +6dB on a full-scale signal to benefit from the SACD headroom.

48V This button will turn on 48V phantom power for the channel. If it is lit, it means that Phantom power is active. Only active on channels set to Mic.

The total current drawn on the phantom power by all the microphones should never exceed 48mA for the whole device

If a MAJOR (by MAJOR, we mean that the threshold of short-circuit detection requires at least 10 Preamp inputs to be shorted simultaneously) 48V Phantom Power Supply short circuit is detected, 48V is forced off on all A/D channels and the following error message is displayed.

"48V power failure: all A/D 48V forced off until next reboot"

This warning applies ONLY to the initial RUN 3 production batch of AD8 and AD8P and has been fixed for all modules shipped starting November 2012: The 48V power MUST be turned off prior to changing the connection in certain patch bays. Many such patch bays do short the Hot, Cold or both signals to Ground during insertion or removal of the Jacks with the risk of deteriorating permanently the protective resistors in the input of the PreAmp circuitry. If an AD module input circuitry is damaged, following such a short, it will end up permanently having inaccurate gain levels, distortion or even no signal at all on some channels. That would require hardware replacements at your own cost, since such damage is not covered by our warranty. If you still own one of the original and unmodified RUN 3 AD8/AD8P modules we recommend that you contact your Merging reseller to organize an update of your module(s), which Merging is pleased to provide free of charge.

Zlo – Zhi Mic input impedance (only available for ADA8, AD8D/AD8DP run 9 and above) and AKD8D/AKD8DP modules.

For the different mic input impedance values, please refer to the card specifications.

PAD (P - B) A -10 dB Pad can be applied in the Mic Preamp circuitry. B- Boost: Increases the mic input signal level by 12 dB > Max input level 0dB Note: The Boost is only available for the modules ADA8S and ADA8P Recommended for Ribbon Microphones that have low output.

∅ Polarity invert button. When lit, it inverts the polarity of the selected input signal.

80 Hz (Hz) Low cut filter 80 Hz. Second order, 12 dB/octave.

Meters dB scaling The Meters scaling is displaying from -90 dBFS to 0 dBFS.

Meters color range Refer to the Meters Page Settings, in order to adjust the Level meter color range (Peak, Alignment and Decay time).

Rst Stands for Reset Peaks Hold Meters. The top Red led of the PreAmp metering will indicate that a Peak has occurred. In order to clear the Peak display, simply press the RST button on the remote web access. To reset the peaks on the OLED you must refresh the PreAmps Page by going to previous one and back. Enabled the Peak Hold option under the Meters menu Settings

Navigation Use the left << and right >> arrows in order to navigate through the banks of 8 inputs. Will be active if more than one AD8(P) module is present in the unit.

Setup Menu

The Setup menu's primary page contains function buttons described below as well as sub-menu links listed in the sub-sections; Formats, Routing, Modules, Presets, System, Network and Info

Formats Menu (Setup)

Sample Rate: Select the Hapi Sampling Rate

44.1 kHz - 48 kHz - 88.2 kHz - 176.4 kHz - 192 kHz - 384 kHz - DXD/DSD Note: The available Sampling Rates depend on the Hapi Analog module cards. Only Premium Analog modules offer support beyond 192 kHz.

Auto Auto Sampling Rate mode. Hapi will automatically follow the sampling rate given by a RAVENNA source provided by; ASIO / Virtual Audio Device (Formerly Core Audio Driver), MassCore or another Horus/Hapi) or external Input Sync source.

Example 1: User using an external player (such as jRiver) can enable the Auto mode so that Hapi automatically changes its sampling rate according to the media file being played back. Provided at least one RAVENNA ASIO or Virtual Audio Device (formerly Core Audio) stream is connected to an Output of the Horus/Hapi

Example 2: This Auto setting can apply to user running the RAVENNA ASIO or Virtual Audio Device (formerly Core Audio) so that Hapi adapts its sampling rate automatically. Provided at least one RAVENNA ASIO or Virtual Audio Device (formerly Core Audio) stream is connected to an Output of the Horus/Hapi

Example 3: Another usage of this « Auto » sample rate button is to enable the Horus/Hapi locked (e.g. WordClock) to automatically follow the sample rate of the WordClock generator (same applies to AES/MADI/ADAT sync). Provided at least one RAVENNA ASIO or Virtual Audio Device (formerly Core Audio) stream is connected to an Output of the Horus/Hapi

Warning: The Auto sampling Rate option must be disabled if locking the Horus/Hapi devices to reference (e.g. 44.1kHz WordClock) which would be different than the working Sampling Rate Format (E.g. 88.2kHz,,192kHz, DXD.) For MADI, the Auto sampling rate option depends on the MADI framing (48 or 96k frame). Therefore it is recommended to disable the option at sampling rates higher than 48 kHz.

Note: If using ANEMAN with a Sampling Rate Zone the device on the Crown will decide the Master sampling rate of all the devices present in the Zone. In such a case it is recommended to disable the Hapi MkII Auto Sampling Rate mode to avoid fights over the sampling rate of the non-Crowned devices at a given moment, since those could potentially cause sampling rate flickering.

A/D Mode in DXD/DSD: This format setup only applies to the AD module which can be set to either DXD - DSD64 - DSD128 - DSD256

Note: The Hapi can be configured in DXD/DSD and in this mode the Hapi can receive any audio data format stream and can generate DXD or DSD(64, 128 or 256) stream depending on the A/D audio data format chosen.

WordClock Output: 44k1 / 48k: When enabled the Wordclock Output will be at either 44.1kHz or 48kHz

Example:

Sampling Rate: 44k1/88k2/176k4 the WordClock Output will be 44.1kHz Sampling Rate: 44k/96k/192k the WordClock Output will be 48kHz.

Follow SR: When enabled the WordClock Output will follow the Sampling Rate selected.

Example:

If the selected Sampling Rate is 48k the WordClock output will be at 48kHz If the selected Sampling Rate is 176k4 the WordClock output will be 176.4kHz

Pull Up/Down: Slow down or accelerate audio clock by 0.1 % depending of the frame rate of the video reference.

This option will only be active if the sync source is configured to Video Ref. The Status of this option can be viewed in the IO&Sync page under Status - Off: Normal operating mode

- Up: Accelerate the clock by 0.1%. Supported only with a Video reference at 24fps and 30fps

- Down: Slowdown the clock by 0.1%. Supported only with a Video reference at 23.98fps and 29.97fps

Routing Menu (Setup)

Module routing menu describes where the signal for each module in the Hapi is coming from. Each button leads to a sub-menu that allows the user to change the source of the signal to that specific module. For instance, the Headphone in the Routing menu will allow the user to change the routing of the Headphone.

Choices are made in blocks of 8 channels from the OLED (except for the Monitor, which is a Stereo signal). As of the Hapi MKII single channel routing is supported but has to be performed via the RAVENNA Advanced pages. For more information refer to the Advanced Pages online guide. https://merging.atlassian.net/wiki/spaces/PUBLICDOC/pages/4819571/Merging+RAVENNA+Advanced+Pages+User+Guide.

Note: The Hapi MKII is different from its predecessor Hapi and Horus since it is based on a routing architecture, each routing performed remains exclusive but without automatic stream connectivity. So, following an internal routing if the operator decides to revert to its preceding RAVENNA routing this one will have to be reconnected in ANEMAN to stream back audio.

Here the AD8 module is routed to the DA8 module and it will remain available for RAVENNA routing

ADAT: Takes you to the ADAT Routing configuration page (refer below)

AES: Takes you to the AES Routing configuration page (refer below)

D/A: Takes you to the D/A Routing configuration page (refer below)

PT64: Takes you to the PT64 Routing configuration page (refer below)

MADI: Takes you to the MADI Routing configuration page (refer below)

HEADPHONE: Takes you to the Headphone Routing configuration page (refer below)

SPDIF: Takes you to the SPDIF Routing configuration page (refer below)

A/D: Disabled as one cannot route TO an Input!

Loopback: Takes you to the Loopback module (present only in debug mode)

Warning: Two inputs can't be routed to the same output, as we are routing channels and not mixing.

Routing: Source Configuration

ADAT - AES - D/A - MADI - SPDIF Routing Output Source (similar)

For all of the output modules (ADAT/SPDIF,AES, D/A N, PT64, MADI & Headphone Jack) the user can set where the signal feeding it comes from. Any combination is possible using the Output source page linked to any of the output modules.

* All routing in the Hapi is currently achieved using banks of 8 channels.

Unrouted: No internal routing has been performed, the module remains available for RAVENNA and/or internal routing

ADAT/SPDIF: Sets the module being configured to receive signal from the ADAT/SPDIF

AES: Sets the module being configured to receive signal from a bank of AES-EBU inputs.

MADI: Enables the module being configured to receive signal from any 8-channel bank in either of the MADI streams

PT N: Enables the module being configured to receive signal from any 8-channel bank in either of the PT64 modules.

A/D N: Sends the signal coming in from the Mic or Line input modules to the output module being configured

Loopback: Should only be used for test purposes.

Routing Example:

MADI Routing Output: Users can route literally any input signal to any output module. Users can also route any input signal to any combination of output modules. Signals are routable in blocks of 8 channels.

The example picture below shows the MADI output1-8 routing being selected from the Routing page on the ADA8 module channels 1-8

With Hapi MKII single channel routing is supported but has to be performed via the RAVENNA Advanced pages. For more information refer to the Advanced Pages online guide. https://merging.atlassian.net/wiki/spaces/PUBLICDOC/pages/4819571/Merging+RAVENNA+Advanced+Pages+User+Guide.

Load: 5 presets banks of different Hapi configurations can be loaded (one at a time)

Save: 5 presets banks are available to store different Hapi configurations

Auto Save: If enabled the save configuration will happen at every 2 minutes.

Note: Since the flash memory which is at the heart of the Hapi storage has a huge (but not infinite) amount of write cycles, we limit the auto-save of all configuration and PreAmps settings to once every two minutes if (and only if) a change has occurred meanwhile.

Furthermore, both Shutdown and Reboot buttons (in Setup page) do also entirely save the current configuration of the Hapi prior to power down.

System (Setup):

ASIO Clock: If set to Auto enabled: The ASIO clock will be generated by the Hapi which will be PTP Master.

If Auto is disabled: The ASIO clock will always be generated by this Hapi.

Note: Do not disable unless you are sure that no Hapi will be PTP Master.

Home Page: Users can decide what will be their Hapi OLED Home Page. You can return to the Home Page by performing consecutive 1 sec push hold or by pressing and releasing the Hapi front panel Home Page button (small Pyramid). Users can also set a Home page display delay option of; 15 seconds, 30 seconds, 1 minute or set it to Never (disabled).

A/D Metering: The screensaver redirects you to the AD Meters Page.

D/A Metering: The screensaver redirects you to the DA Meters Page.

In Levels: The screensaver redirects you to the Input Level Page.

Out Levels: The screensaver redirects you to the Output Level Page.

Volume: The screensaver redirects you to the Volume Page.

Long push the Rotary Control to exit those pages.

Screensaver: The Hapi screen will turn black after a 1min delay without user interaction. This is in order to preserve the life span of the Hapi OLED display. To exit the Screensaver press the Rotary Control Button.

Latency: The Hapi has 4 Latency Settings (in samples) that will determine the device latency over a RAVENNA network. When multiple RAVENNA devices (e.g. Horus & Hapi) are connected over a network, they adjust themselves to the lowest latency that can globally be achieved.

• Ultra Low (16 smp)
• Extra Low (32 smp)
• AES 67 (48 smp)
• Low (64 smp)

Terminations: 75Ω for WCK: Sets 75Ω termination for the Wordclock Input. 75Ω for Video: Sets 75Ω termination for the Video reference Input. Unless the Video Reference signal provided to the Hapi is daisy-chained to other equipment, you should always terminate your Video signal for most reliable operation.

Brightness: Users can set the Hapi Power Button and OLED display luminosity. This may save some power and hence some internally generated heat.

Note: during the adjustments the OLED will flicker black and update the brightness value.

Network Menu (Setup)

Device Name: Name of the Hapi unit. This name will be broadcast across the network and will be seen in applications such as the MT Discovery tool or ANEMAN. The Hapi unit name can be changed from the Web control access Network page (see section below for all details)

IP Settings: Manual: Type IP address using box selection and the - or + buttons Auto: The IP address will be automatically attributed using ZeroConf/Auto-IP mechanism (address range 169.254.xx.xx if no DHCP server is present)

Address: Set the IP Address for the Hapi unit by using box selection and the - or + buttons (Available only with IP Settings = Manual)

Netmask: Set the Subnet Mask for the Hapi unit by using box selection and the < or > buttons (Available only with IP Settings = Manual)

Apply & Reboot: Once changes have been made to this section, you must press this button to save the settings and power cycle the Hapi unit

Note: Hapi has no DHCP-server capability neither does the Merging PCIe Ethernet Controller Card NET-MSC-GBEX1. By default the Hapi IP setting is set to "Auto" configuration mode which gives an address in the range 169.254.xxx.xxx if no DHCP server is present on the network. Users are free to put a DHCP server in their RAVENNA network with a customized address range and the Hapi would get an IP address from this server. Note that our recommended RAVENNA switches are configured with DHCP disabled.

Merging recommend the Hapi to be configured in "Auto" mode and the Merging PCIe Ethernet Controller Card NET-MSC-GBEX1 to also be configured with "Internet Protocol Version 4" with "Obtain an IP automatically".

The Hapi MKII RAVENNA provides two network operation modes.

1- ST2022-7 Seamless Protection Switching
2- Network Switch mode (default). Allowing daisy chain for an extra network device
Those modes of operation are available for selection from the RAVENNA Advanced Pages. Find more details here.

RAVENNA Network For Edit / Mix Suite with Seperate Machine Room

Description

The workflow example shows a typical dubbing and edit suite connected to a local machine room which contains all of the heat sensitive and noise generating equipment.

The Network is being used to connect the RAVENNA enabled equipment together. But, as RAVENNA can exist on the same network as other streams of information, the same network is being used to create the connection for the Tango2 control surface as well as to extended the DVI and keyboard/mouse connections for the Pyramid MassCore workstation. The video for the main screen is being tied from the SDI output of a VCubeHD which is running on the same workstation as the Pyramid MassCore.

RAVENNA Network for Multiroom Museum Installation

RAVENNA Network for Multiple Mastering Suites with a Shared Machine Room

Description

This workflow example shows how best to connect 3 Pyramix suites to a single, shared machine room.

The Machine room contains all of the source machines (1/4" tape and other linear sources) that are controlled using the sync outputs of the Horus unit. The RAVENNA streams pass from the Horus into the Gb LAN switch and can then be accessed by any of the suites. As the control for the line inputs, as well as the sync information for the Horus is over the same network connection as the RAVENNA streams, it means that only one cable needs to go to the machine room. Control over the Pyramid is made with a second network connection to the Tango2 control surface.

Each DABP line output card is connected to its own studio, providing discreet line outputs (S.1 Surround + Stereo) to each mastering suite)

It is also important to note that the RAVENNA connection will also allow for signal to be easily and instantly shared from control to control room as well, as any interconnections is possible over the RAVENNA network.

• Talkback Microphone

Description

In this signal diagram of a RAVENNA network we are showing an incredibly useful feature of the Horus Interface. Each 8 channels of input or Output can be shared between a Number of DAW's, OR dedicated to a specific one, allowing for professional quality I/O to exist in each dubbing suite, even though it is all being managed by a central piece of equipment.

The diagram also shows that, by use of an ASIO or CoreAudio RAVENNA driver, 3rd party DAW solutions on either Mac or PC can connect to the RAVENNA network. This means that they can use and share the Horus I/O as well as share signal in between each workstation, provided of course all workstations operate at the same common sampling rate

RAVENNA Network for Multiple Studios with a Shared Live Room

Description

This workflow example shows how best to connect 3 Pyramix suites to a single, shared live room.

The RAVENNA streams pass from the Horus into the Gb LAN switch and can then be accessed by any of the suites. As the control for the Mic-Pre Amps in the Horus is over the same Network connection as the RAVENNA stream, it means that only one cable needs to go to the live room.

In each control room, monitoring is achieved by using the "Secondary Audio Device Router" in Pyramix. This allows a locally connected Audio interface to be used for multichannel monitoring as well as talkback to the musicians in the live room. It does this by bridging the Secondary Audio device into the RAVENNA network so that all of this routing can happen transparently in the Pyramix Monitoring section.

Control over the Pyramid is made with a second network connection to the Tango2 control surface.

It is also important to note that the RAVENNA connection will also allow for signal to be easily and instantly shared from control to control room as well, as any interconnections is possible over the RAVENNA network.
