DL431 Introduction

EN 1. Introduction

The DL431 Mlc Splitter is a six-unit (5U), high 19" rack unit that provides 24 mlc/ line inputs. Each input feeds three separate pramps, two of which have separate remote and local gain controls, while the third has fixed gain. The two pramps with gain controls feed separate analogue to digital (AVD) converters, which pass digital audio to the network. Four discrete AES50 outputs supply dual redundant digital audio to front of house (FOH) and monitor XL8 systems, and allow for easy routing to any third-party AES50 device, such as a recorder, via DL461 routers.

Two balanced analogue splits — sourced from post-each mic amp — are provided on the rear panel. The third preamp (fixed gain) feeds a transformer isolated split on the front panel for recording or broadcast applications.

Front panel control and local monitoring, including integral headphone amplifier, enhance the DL431's features, and dual redundant internal power supplies ensure worry-free operation. Four DL431s are supplied with each XL8 system to provide 96 input channels.

ES 6. Operación

EN Using the 30 Hz filter

The DL431 Mic Splitter's 30 Hz filter is an analogue high pass filter (IIFF). It is a very low frequency signal filter with a 30 Hz corner frequency and 12 dB per octave Butterworth roll off. This filter can be switched into circuit following the mic amp to make better use of the analogue-to-digital (A/D) conversion headroom by removing the very low frequency audio content.

High pass filters are used to remove unwanted subsonic frequencies, which are traditionally about 30 Hz. A typical use for this filter is to reduce rumble.

Cleaning the internal fans

The unit's internal fans need to cleaned regularly to remove the build of dust, dirt etc. We recommend that they are cleaned at least once a year, provided the unit has been operated under normal conditions. However, if the operating conditions are more adverse or extreme, for example, if the unit is operated in the vicinity of smoke machines, new carpets etc., this frequency should be increased accordingly.

This procedure must be carried out by a fully qualified service engineer.

Appendix D: Service Information

(1) The XL8 Live Performance System is a very powerful and flexible audio processing system that provides a complete solution for any audio mixing and signal distribution application in a live sound environment.

The standard XL8 system offers 96 channel inputs, 51 outputs, 51 buses (32 auxes/groups, 16 matrices and three masters), 16 on-board effects processors, PEOs (four-band on inputs and six band on outputs), up to 48 assignable GEOs (of all stereo effects units are being used), 16 configurable stereo effects (from eight options), surround panning (5.1, LCRS and quad) and comprehensive, easy-to-use routing. XL8 automation provides up to 1,000 scenes with snapshot save/recall capability and global edit, presets and show file archiving.

The XL8 Control Centre forms the core of the XL8 Live Performance System, which also includes a number of 19" rack modules that are interconnected by a networked data system. The network carries both proprietary control data and open architecture AT550 digital audio, and uses readily available standard cabling and connectors. The XL8 uses the proven stable Linux operating system. Third party hardware and software (and plug-ins) can be easily integrated into the system.

Included with the XL8 Control Centre are four mic splitters, five I/O units, 10 DSP units, two routers and a Klark Teknik DN9331 RAPIDE that, collectively, form the standard XL8 Live Performance System configuration.

The XL8 Live Performance System is tolerant of any single failure of hardware or software. To achieve this the system employs dual redundancy, where a key component has an identical redundant spare that is ready to take over should it fail. Other failure scenarios are managed by the N4-1 principle, where redundant components form an acceptable fraction of the system, for example, one of the DSP units in the rack is a redundant spare.

System interconnections

Figure 1 shows basic system interconnectivity and indicates where the XL8 Control Centre (highlighted in red) sits within the system. This figure also illustrates redundancy by showing that the two halves of the system - left and right - are identical (ignoring the DM9331 RAPIDE).

The XL8 Control Centre, which forms the core of the XL8 Live Performance System, is directly connected to the local I/O units, DN9331 RAP/DE and routers (via the "snake"). Each router acts as a hub and is connected to the mic splitters I/O units and DSPs, which are common to both halves of system. The network carries both proprietary control data and open architecture AES50 digital audio, and uses readily available standard Cat 5c, Cat6/fibre optic cabling and connectors.

Mix matrix

Ultimately, the mix matrix defines the XL8 Control Centre's capability. Probably the best way to imagine the mix matrix is to think of an analogue console layout, where inputs run vertically and buses run horizontally. A mix matrix is usually defined as the number of buses and the quantity of simultaneously mixable inputs there are per bus. The following diagram illustrates the capability within the control centre.

The standard XL8 Live Performance System has a total configurable audio channel count (on the DL451 I/O units) of between 120 and 240, depending on the mix of analogue and digital I/O (excluding the non-configurable 9% mic inputs on the DL431 mic splitter).

Typically, the allocation would be:
• 16-off mic/line auxiliary inputs (giving a total of 112 mic inputs as standard).
• 32-off axx/group bus outputs.
- 16-off matrix (main) outputs.

1-off stereo main output.
- 1-off mono main output.
- 2-off stereo local monitor outputs.
This gives a total of 71 audio connections, leading a further 169 (with everything digital) or 49 (with everything analogue) audio connections. These can be used for insert sends, insert returns, direct outputs, bus direct inputs and side chain connections.

EN Appendix E: XL8 Live Performance System

The maximum count of any one type of connection is:

• % off input insert sends.
• 96-off input insert returns.
• • %-off input compressor external side chain connections.
• 96-off input noise gate external side chain connections.
• 96-off input direct outputs.
• • .51-off mix bus insert sends.
• 51-off mix bus insert returns.
• 51-off mix bus direct inputs.
  • 1-off talk mic input.

However, the XL8 can have much more than the standard connectivity by adding DL451 I/O units. As there are nine AES30 connections ^1 (fully redundant) available, potentially, another 432 audio connections can be achieved (subject to other system limits). This gives a maximum XLR count of 720. Figure 3 shows a system configuration containing the extra nine DL451 I/O units, but does not show the redundant duplicated network.

All connectivity is controlled via the GUI.

Surround capabilities

Theatres and broadcast have differing requirements for surround, and both are catered for in the XL8.

Conventional stereo and SIS ^™ panning is assignable on a channel by channel basis (channel one can be in stereo while channel two can be in SIS ^™ ), as follows:

• Stereo left-right routing to master buses.
• SIS™ left-right-centre routing to master buses.
  Three additional surround modes operate as follows:
• Quad felt, right, LS and RS].
• Surround (left, right, centre, surround).
• 5.1 surround (left, right, centre, subwoofer, LS and RS).

Network

The XL8's digital audio network utilises the physical connectivity of Ethernet (EtherCon® connectors and Cat Se/Cat6 cable), but replaces its data protocol with AES50 protocol (Implemented as SuperMAC) and the HyperMAC high capacity system, which are more suited to high quality, low latency audio distribution. The use of the AES standard allows straightforward interfacing with any third party hardware that also utilizes this connection.

AESSO and HyperMAC connections carry digital audio, control data and standard Ethernet traffic by directionally down a single cable. Cat 5c cable is used for the local (24-channel) connections and the single digital "smoke" — between control centre and router — is either Cat 5e/Cats or fibre optic. The combination of audio, control, clock and third party Ethernet data in a single network means that the hardware interfaces on a single R45 connection.

1. These spare AESSD ports can also be used to directly connect any AESSD equipped units, such as a hard disk recorder.

2. The digital snake is equivalent to a 384-channel analogue multi-core cable (192 channels in each direction).

All system connections are duplicated for full dual redundancy.

Resilience to failure (redundancy)

The XL8 Live Performance System is tolerant of any single failure of hardware or software. To achieve this the system employs dual-redundancy, where a key component has an identical redundant spare that is ready to take over should it fail. Other failure scenarios are managed by the K+1 principle, where redundant components form an acceptable fraction of the system; for example, one of the DSP units in the rack is a redundant spare (see Figure 4 on page 43).

The control surface can tolerate multiple hardware failures without the operator losing control of the audio. Any of the live GII screens can be used to operate the whole control centre, even if no control surface hardware is working.

The system includes diagnostic tools that give advance warning of any poor connectivity (high error rates), internal temperatures and voltages etc. The system instantly alerts the operator in the event of any hardware, software or connection failures, and indicates the location of the fault. The system asks the operator what action to take, but doesn't automatically reconfigure. This is so that it, for example, the band is near the end of a song and the audio is still alright, the mir engineer carry out corrective action at a more opportune time.

Figure 5 on page 44 shows that even when all of one half of the system is down (the greyed out portion) it will still function as normal. Although, in practice, it is highly unlikely that this will ever happen.

Figure 6 on page 90 illustrates what happens when a router fails. Once again, the system functions perfectly normally.

Appendix E: XL8 Live Performance System

Control software

The XLR's operating system is Linux, which is an open source, stable, proven operating system (OS). Linux is used in many mission critical applications worldwide and has allowed Mides' software engineers to write a ground-up system that contains no 'hidden' or unused code. This has resulted in an efficient, compact application, which is quick in operation, quick booting and comparatively easy to debug.

Two copies of the master control software run on separate processors to provide resilience to failure.

GUI

The XL8 has five, daylight-viewable, TFT screens that provide overview and detail status indication. Any screen can display any information but, in the standard configuration, screen information relates to module location. So, the input module screens display their module's input status, the mix module screen displays the overview status screen (all the motors all the time) and the output module screen display is used for general use, such as automation, effects, GEOs, third party screens etc. This is dependent on the current application (concerts will probably be different to theatre), and also operator preference.

The screens are controlled via the navigation zones at the front of the modules. In the output module's primary navigation zone, two trackballs control the output module (right trackball) and the mix module (left trackball). The equivalent on each input module is a dedicated flickpad. A keyboard slides out from underneath the output module to provide further control, such inserting text. USB keyboard input sockets at the front of the control centre (under the left and right modules) allow the input and mix screens to be controlled via an external keyboard should the output module screen fail.

Console linking

Two XL8 Control Centres can be linked together, as you can with Heritage consoles. The bus outputs from one control centre feeds the bus inputs of the other, which is done using AES50 links.

Integration of third party software

The XL8 network includes the capability to interface any third party hardware that uses AES/EBU or AESSO digital audio, or a standard analogue audio interface.

Each XL8 AES/EBU input and output has a sample rate converter. Synchronisation to external AES3 interfaces can be:

- Global - via Inputs on the routers.

- Local to each input.

- Local to each output (synchronisation to adjacent local output).

Multiple local connections can be at different sample rates.

The use of the A1550 protocol for the transmission of digital audio means that any third party digital audio hardware that features this connection can be connected to the Midas network, and will transfer audio to and from the Midas hardware without any additional interfaces or converters (provided it runs in TDA 96 kHz mode). This will be particularly useful as the protocol gains acceptance with recording and playback devices, loudspeaker controllers, audio networking systems, digital amplifiers etc.

PC or MAC computers can use the Ethernet tunnel in the MidasNET system, and can communicate with other computers on the network.

Integration of third party software 47

The XL8 Control Centre features a four-way KVM switch on the output module screen, as well as external video IN and OUT for each of the five screens. Control centre views can be routed to external monitors, and external video sources can be displayed on the control centre's screens.

The KVM switch facilitates the control of three external computers from the screen, trackball and keyboard of the control centre. This is hugely important and means that third party systems can be controlled from within the XL8 without having to move your head to look at screens placed off to one side. It also means that there is no need to find somewhere to put multiple keyboards and mice. Examples are:

• ProTools. Right in the middle of the XL8! Link ProTools and XLS audio digitally and use any ProTools plug-in as an insert to the XL8!

- Netmax (AES/EBU audio link initially and Cobranet when the 48 kHz I/O module is available on XL8).

- IRIS (for example, for RL amps).

• KT Elgar (via Ethernet tunnel from FOII to stage).

- * Wireless mic controllers.

- Your email.

• DVD movies.

This chapter shows you how to set up an XL8 Live Performance System to its default configuration.

Note: if you want to set up the XL8 Live Performance System using a configuration other than the default, please contact Midas Technical Support for details.

Initial set-up procedure

Initial system set-up basically comprises:

• Unpacking and checking the equipment — see "Unpacking the equipment" below.
  • Making up the racks — see "Making up the racks" below.
• Connecting up the equipment — see "Wiring instructions" on page 51 and "XLS system interconnections" on page 54.
• Powering the equipment — see "Powering the XLS system" on page 57.
• Initial patching:

- Configure the type of snake — see "Configuring the XL8 with the snake type" on page 30. It is important to configure the XL8 with the correct type of snake connected in the system.

- Setting up the I/O rack devices — see "Configuring the devices" on page 29.

- Configuring the DL4n1 units — see "Setting up the ID of the DL4n1 units" on page 59.

Unpacking the equipment

After carefully unpacking the equipment, check it against the packing list shown in "System components (standard supply)" on page 34.

Save all packing materials, as they will prove useful if you need to transport the equipment later.

Inspect the equipment carefully for any sign of damage incurred during transportation. It has undergone stringent quality control inspection and tests prior to packing and was in perfect condition when it left the factory. However, if the equipment shows any signs of damage, notify the transportation company without delay. Only you, the consignee, may institute a claim against the carrier for damage during transportation.

Making up the racks

After you have unpacked the XL8 Live Performance System and made sure everything is there, make up the racks. In the default set up there are three stage rack units and one FOH rack unit, which should be set up as shown in "XL8 system interconnections" on page 54.

Although rack unit set-up is fairly straightforward, there are careful considerations to be addressed beforehand, which are outlined in the following subsections.

Outboard equipment racks

To ensure the correct installation and function of the outboard equipment, such as the DL4n1 units and DK9696 recorder, the racks must meet the following general requirements.

- Shock mounting (for non-installation environments): The racks must provide adequate shock protection of the units they house by incorporating appropriately-designed shock protection methods, for example, a foam-suspended rack or a frame suspended on anti-vibration mounts etc.

• Ventilation: The XL8 rack units have been designed such that their internal ventilation airflow is drawn in through the front of the unit and expelled through the rear. To facilitate this, rack design must ensure that orol air can flow freely through the rack in the same direction, that is. In through the front of the rack and out through the rear. Situations where the air flows in a circular direction around and through an XL8 unit must be prevented. Midas recommends that racks with fully opening front and rear doors are used.
  Note: Never combine units in the same rack that have been designed for a ventilation air flow direction other than that for the XL8 units. To avoid this, we recommend that any non-XL8 units are housed separately.
• Rack mount supports: Always secure the rear of the XL8 units to the rack via their rear rack mount support brackets. These brackets are fitted to every XL8 unit and are recommended for use in touring applications. The rack mount support fixing hole centres are at a depth of approximately 395 mm from the front panel [this dimension may differ slightly on the CNP956].
• Handles on rack case: You must ensure that there are sufficient external handles fitted to the rack casing to enable the rack to be manoeuvred easily and safely, and by the amount of personnel suitable for the task. Also, these handles must be fit for purpose.
• DSP rack only: Midas strongly recommends that the DSPs and routers are housed in a single rack, that is, stage rack 2 (see "Stage rack 2" on page 51). This rack can be either a 16U high (minimum) rack or configured as an 8II double rack.
• Clearance at rear of units: To ensure an adequate clearance at the rear of the units, we recommend that the rack depth, that is, the distance from the front rack strip to the rear of the rack, is a minimum of 700 mm. This is to provide sufficient free space to enable the DSP link cables to achieve their minimum bend radius.
• Securing the cables: We recommend that the cables at the rear of the units be ticked using facing bars and cable ties. This should provide optimum access to the rear of the units for connecting other cables, switching the units on/off etc., and give maximum visibility of the units' LEDs for determining communication status, link status, condition of audio etc. The picture (right) shows a good example of how this can be done. For more information on cabling, refer to "Stage rack 2" on page 51.

Interior view of an electronic equipment rack with exposed wiring and circuitry (no visible text or labels)

Stage rack 2

Stage rack 2, also known as the "DL461/DL471 engine rack", contains the two routers and 10 DSP units.

Important:

In general, the physical location of the hardware units within each rack is not critical, and alternative configurations are acceptable for different packaging preferences. However, best practice is to mount the DL471 units in numerical order, which will aid quick identification and fault finding.

DL471 unit ID numbers are located on stickers on the top cover of each device and also on the carton. These must be noted prior to build-up and connected, as shown, in numerical sequence. Please note that once initially configured, the ID numbers are displayed on the top row of the DL471 screen and role numbers are on the bottom row. The role numbers are dynamic and, therefore, may change during system operation.

Wiring instructions

This section gives the system cabling details for the 30.8-specific equipment and, although it is laid out in recommended order, this order is not critical.

When making the connections, please make sure they match those in "XL8 system interconnections" on page 54. Further details are shown in "Cable type and function" on page 56.

>> To connect both routers together

Important:

Without this connection system snake redundancy will be compromised.

Connect the routers via their Ethernet socket of the control expansion section on each router's rear panel (see "System interconnection panel" on page 253).

>> To connect the XL8 to the routers

Connect the 'snake' [optical or copper] from the X snake socket on the rear of the XL8 Control Centre to the appropriate snake socket on the X Router. Repeat for the Y Router using the Y socket on the XL8 Control Centre.

>> To connect the routers to the DSPs (Stage rack 2)

>> To connect the routers to the Stage rack 1 units

• In AES50 audio - bank 0 on the X router, connect the 10 sockets to the AES50 audio X socket on the DSP units. Repeat for the Y router, using the equivalent Y sockets.
• In Ethernet control bank on the X router, connect the 10 sockets to the Ethernet control X socket on the DSP units. Repeat for the Y router, using the equivalent Y sockets.
• Mic splitters: In AES50 audio - bank 1 on the X router, connect sockets 1 and 2 to the AES50 audio - A X sockets on the Mic Splitters. Repeat for Y router, using the mic splitters' Y sockets.
• Line I/O units: In AES50 audio - bank 1 on the X router, connect sockets S and S to the AES50 audio X sockets on the line I/O units. Repeat for Y router, using the line I/O units' equivalent Y sockets.

EN

>> To connect the routers to the Stage rack 3 units

• Mic splitters: In AES50 audio - bank 1 on the X router, connect sockets 3 and 4 to the AES50 audio - A X sockets on the mic splitters. Repeat for the Y router, using the mic splitters' Y sockets.
• Line I/O unit: in AES50 audio - bank 1 on the X router, connect socket 6 to the AES50 audio X socket on the line I/O unit. Repeat for the Y router, using the line I/O units' equivalent Y socket.

>> To connect the XLS to the line I/O units (FOH rack)

Connect the AES50 audio X sockets on the rear of the XL8 Control Centre to the AES50 audio X socket on both of the line I/O units in the FOH rack. Repeat for the Y sockets.

>> To connect the XL8 to the RAPIDE

Connect one of the eight ETHERNET (EtherCon" XLR) sockets on the rear of the RAPIDE unit to the Ethernet control 1 socket of the active network (X or Y) on the rear of the XL8 Control Centre (see "XLR system interconnections" on page 54).

To daisy chain the DSP units

Important Note:

Do not connect a cable to like numbered sockets, that is, "0" to "0" or "1" to "1", as the DSPs will not work; socket numbers are printed to the right of each socket.

There are two default configurations available, depending on the lengths of the interconnecting DSP cables supplied, that is, 0.25 m cables or 0.5 m cables. Both options contain a long cable for connecting the top and bottom units, and the 0.25 m option has an additional long cable for connecting units ANU 2 and ANU 9.

A cable's length (cm) can be determined from a three-digit number contained within its part number (printed on a label attached to the cable). For example, in a part number of "14150-5788-050-01C 060425 7D" the "050" indicates a length of 50 cm.

Connect the DSPs together as shown in the following diagram, according to the cables supplied with your system. (In the diagram, the cables are coloured and the sockets numbered to help distinguish them.)

Powering the XL8 system

The following details the recommended power up and power down procedures for the XLB system.

>> To power up the XLS system

Important Note:

DO NOT switch on the speaker sub-system until after the start-up of the XL8 system has been completed.

After all XL8 system interconnections have been made [see Chapter 30 "Panel Connections"], start up the XL8 system.

1. Make sure that all of the XL8 system equipment is switched off, that is, the XL8 Control Centre, speaker sub-system, DL-431 mic splitters, DL-451 modular line I/O units, DL-451 routers and DL-471 DSP units.

2. Switch on the XL8 Control Centre (see "To switch on the XL8 Control Centre" on page 58).

3. On the XLB Control Centre, move all of the monitor and master channel faders to the minimum position and mute all of the master channels. The master channels can be found in the mix and output fast zones (see "XLB control surface" on page 7).

4. Switch on the DL431 Mix Splitters.

5. Switch on the DL4S1 Modular I/O units.

6. Switch on the DL471 DSP units.

7. Switch on the DL461 Routers.

8. After the status LEDs (top of each GUI screen on the XL8 Control Centre) turn green, switch on the speaker sub-system.

9. Switch on the audio source and start playing the audio.

10. On the XL8 Control Centre, check that the audio inputs are routed to the master channels. Then, unmute the master channels and gradually increase their faders, while listening to the sound levels from the speakers.

If there are no sounds at all from the speakers when the leaders are at maximum, move the leaders to below the 0 dB level and check if the audio is muted somewhere along the input paths and also check that the individual speakers are switched on. If there is still no sound from the speakers, contact Midas Technical Support.

>> To power down the XL8 system

Important Note:

BEFORE switching off any of the XL8 system components, make sure to mute the audio from the speakers and switch off the speaker sub-system.

1. Mute the audio from the speakers and switch off the speaker sub-system.

2. Switch off the DL431 Mic Splitters.

3. Switch off the D1451 Modular I/D units.

4. Switch off the DL471 DSP units.

5. Switch off the DL461 Reuters.

6. Switch off the XL8 Control Centre (see "To switch off the XL8 Control Centre" on page 59).

Appendix F: Setting Up An XL8 System

Switching the XL8 Control Centre on/off

Carry out the following to switch the XL8 Control Centre on/off in a safe manner, observing all WARNINGS and Cautions.

To switch on the XL8 Control Centre

WARNING! DO NOT INSERT OR REMOVE A POWERCON® CONNECTOR INTO/FROM REAR OF CONTROL CENTRE WITH MAINS POWER AND ANY OF THE MAINS BAY SWITCHES ON. YOU MUST MAKE SURE ALL MAINS BAY SWITCHES ARE OFF AND MAINS IS SWITCHED OFF AT THE POWER OUTLET(S) FIRST.

Caution! Before switching on, check that all monitor loudspeaker power amplifiers are turned off or muted. After connecting up the audio cables, carry out the following:

Rear of XL8 Control Centre

1. Plug the two control centre's mains PowerCon® cables into the mains power outlets.

2. Insert the two mains PowerCon® connectors into the PowerCon® sockets on rear of control centre, observing the WARNING! above. Then, lock each one by twisting the PowerCon® connector about 90° [1/4 turn] clockwise; you should hear a click when it has locked in place. Check that both PowerCon® connectors are securely fitted.

3. Observing the Caution! above, switch on all five bay mains on/off switches, one after the other. It is important that you don't switch on two or more switches simultaneously.
4. The control centre will power up; the GUI will display the default screens and all the controls will be set to default. You are now ready to start using the XL8 control centre.

   To switch off the XL8 Control Centre

5. Make sure you have saved any shows, scenes or settings you require (see "Saving your show files to a USB memory stick" on page 56).
6. At the GUI, choose home ▶ Preferences ▶ Shutdown System
7. At the Shutdown ENTIRE system? prompt, click OK. This initiates the shutdown down sequence.

During the shutdown sequence the GUI screens will shutdown and all of the LCD select buttons on the control surface will turn red. To inform you of the shutdown status, the LCD select buttons in the input bay's VCA/POP group sections will also display individual and contiguous text messages, respectively.

When the shutdown sequence has finished the LCD select buttons on the control surface will turn green, and the appropriate ones will also display text messages, accordingly.

Important:

During the shutdown sequence, when the LCD select buttons on the control surface are red, do not switch off the mains power supply, and when they are green, it is OK to switch off the mains power supply.

1. Make sure that the shutdown sequence has finished, and then switch off the five bay mains on/off isolator switches (rear of control centre), one at a time.
2. Disconnect the two mains PowerCon® connectors from the PowerCon® sockets on rear of XL8 Control Centre. To unlock them, twist by about 90° (1/4 turn) anti-clockwise.

Setting up the ID of the DL4n1 units

After connecting up your XL8 network system, you will need to set up the ID of the DL431 Mk Splitter, DL451 Modular I/O and DL471 DSP units (if they don't already have the ID you want). This is done via the control panel of the unit.
