2. INTRODUCTION

2.1. Front panel

2.2. Rear panel

2.3. Overview

The multiverter is a unique device which allows you to convert digital audio data in any direction between the most popular formats: ADAT, MADl optical, MADl coaxial, MADl-TP, AES50, Dante and others | via break-out boxes|.

All inputs can freely be routed to all of the outputs, with an arbitrary number of splits and merges supported at the same time.

Channel-wise routing between different interfaces is supported via the remote control via integrated web server, or via command line.

The routing matrix supports 448x448 channels (7x7 interfaces with 64ch each) at single speed modes, 224x224 channels at double-speed and 112x112 channels at quad-speed modes.

Using the optional SRC-64 Asynchronous Samplerate Converter Module (optional hardware), asynchronous samplerate conversion on 64x64 bi-directional channels, up to 192kHz is supported.

The device is prepared for headamp remote control | Yamaha, Behringer, M|DAS|.

Diagnostics are made simple by an integrated headphones amplifier and a test tone generator. Three power inlets allow operation from either AC or DC (battery pack) with full redundancy.

2.4. User interface

The device has been designed for fast and simple operation, with a no-frills everything-at-a glance concept. The unit can be operated either

directly on the front panel

via the integrated web server

via command line▶{telnet or USB}

via M|D| ▶|Preset recall only|

In this manual, the required steps for each operation mode are indicated by

▶ Front panel, ▶ Web and ▶ Command line headers.

All operation modes can be used simultaneously, and any status change is immediately reflected on all interfaces. For example, it's possible to make some routing connections on the front panel, and later change them via the web interface or the command line.

▶Front panel

Most settings are directly accessible without the need to walk through lengthy menus:

■ To change a setting, first push the appropriate rectangular button (e.g. Set). You have now entered "Menu" mode, indicated by a yellow blinking cursor.
■Move the cursor by turning the encoder (rotary knob) left or right to move it to the desired setting.
■When the cursor is at the beginning or end of the column or line, continue turning to make it wrap around.
■Push the encoder knob (or push the appropriate menu button again) to confirm your changes. To return to the previous state without making any changes, push the ▶Back button.
■When the device is normal operation (i.e. not within a menu), turning the encoder knob changes "Volume" or "Channel" of the monitor headphones, while pushing the encoder toggles between "Volume" and "Channel" mode.
■ Channel-wise routing is not available from the front panel due to the lack of controls.

▶Web

Thanks to the integrated web server, the multiverter can be remotely operated from any browser. This is completely self-contained, platform independent and does not need any additional software.

Web control is the preferred method because it offers channel-wise routing and provides the most convenient graphical interface.

The web server runs on the Dante module, and can be configured to run.

(A) on the same network as the Dante audio. This is the normal configuration and allows to use Dante Audio redundancy.
(B) on a separate network, isolated from the Dante audio. In this case, the "Primary" port is used for audio, while "Secondary" port is used for remote control.

|A| Remote control on the audio network

To access the web control, figure out the symbolic name as displayed in the Dante controller, usually MVR-64-xxxxxx (with xxxxxx being some individual number of the multiverted), and type the following into the browser's address bar:

http://MVR-64-xxxxxx.local

Alternatively, you can type the IP address of the Dante module as displayed in the 'Network Config' tab into the address bar, e.g. 192.168.0.204 Please note that, depending on the network configuration, the module's IP address can be reassigned by the server.

(B) Remote control on a different network

■In the Dante Controller, under 'Network Config', set Dante Redundancy to "Redundant".
■Connect the Audio network to the 'Primary' port only and configure it as desired.
■Connect the Control network to the 'Secondary' port and configure it as desired.

General remote control considerations

■The app uses latest web technologies (HTML5, AJAX, Server-sent Events etc.) which require an up-to-date browser. It has been extensively tested with mid-2018 editions of Chrome, Firefox, Safari and Edge. Older browsers - including all versions of Internet Explorer - are not supported!

■You can run up to four sessions at the same time (i.e. have the page open on four different computers). Any change or status update will propagate within a few seconds to all connected devices.

■Web control has been carefully designed to transfer data only when a change occurred (and even then only a few bytes) so it generates virtually no additional load on the Dante network.

▶Command line

Command line control is available via standard telnet, and also on USB |FT2232 COM port). It provides access to all multiverter functions and routings, and is perfectly suited for automated tasks.

■The telnet server listens on the Dante network, on port 2300. Use a telnet client to connect to it:

telnet MVR-64-xxxxxx.local 2300

Alternatively, you may use the |P address of the Dante module, either on the audio network on a separate control network |see Web Control.

■When connected via USB, the multiverters shows up as COM port. Communication can be done with a standard serial terminal i.e. PuTTY or minicoml. Communication parameters are 115200,8N1.

■ To obtain a list of all commands, type help at the MVR> command prompt and press enter.

■To exit a command line session, type exit end press enter.

▶M|D|

The only command understood via M|D| is "Preset Recall". See 4.1. Preset Recall for details.

Besides this command, the M|D| port may be used to receive and transmit M|D| data in order to embed/de-embed it to any MADl stream. See 3.14. Control data forwarding for details.

3. CONNECTIONS OVERVIEW

This chapter gives you an overview of all connections on the back of the device. Please refer to 12. Specifications for full characteristics of each port.

3.1. AC Power

Mains AC inlet, 90-240VAC, 0.75A max.

Together with the DC power port, the inputs are full redundant. If any of the inputs fail, the other takes immediately over. During the switch-over process, full operational state is maintained (i.e. no interruptions in the audio flow).

3.2. DC Power

Battery | DC inlet, nominal 9·18V, tolerates up to 30V.

Maximum current 2.5A, typical operating current < 1A, standby current ca. 10 mA.

Use this port

■to operate independently from AC power, e.g. from a camera battery pack in the field

■as battery backup if the AC input(s) fail. To prevent the backup battery from draining while AC power is present, keep the voltage below 16 volts.

3.3. ADAT/SPD|F/AES3 optical

Eight optical input/output ports are available. Each input and output port can be run in different modes:

■ADAT with up to 8 channels per port
■SPDIF with up to 2 channels per port
■AES3 optical with up to 2 channels per port

For the inputs, the mode is detected automatically. For the outputs, the desired mode can be set individually via the Web UI on the SETTINGS page (see 9.2 Configuration settings).

The ports are mapped to the channels as shown in the table below. Please note that SPD|F|AES3 channel mapping is not linear, but starts with the same channel number as ADAT for each port. This allows to keep all routings the same even when the protocol changes.

Protocol SMUX 1 2 3 4 5 6		Port
		7 8
ADAT x1 1..8	9..16 17..24 25..3	2 33..40	41..48 4	9..56 57..64
SPD|F / AES3	x1	1..2	9..10	17..18	25..26	33..34	41..42	49..50	57..58
ADAT	x2	1..4	5..8	9..12	13..16	17..20	21..24	25..28	29..32
SPD|F / AES3	x2	1	5	9	13	17	21	25	29
ADAT	x4	1..2	3..4	5..6	7..8	9..10	11..12	13..14	15..16
SPD|F / AES3	x4	no: supported

Table 1: Optical port channel mapping

When ADAT, SPDIF or AES3 is used as clock source, Port 1 must be connected and is used as master clock.

3.4. PC/USB

The USB port is used for firmware update, and as Remote Control Port for the PC (serial terminal, 115200, 8N1. See Command line on p.11 for details).

The USB port does NOT carry audio data!

To interface the audio system of the multiverter to a computer, connect is using Ethernet to the Dante port and use the Dante Virtual Soundcard software.

3.5. RS485

The RS485 port is prepared to send and receive Yamaha Headamp Remote control information*.

3.6. Extension

This port is designed to connect break-out boxes to support other, non-built-in protocols and standards [e.g. AVB], or to connect additional ports for system extension.

Currently supported (as of 2019-08):

Product Purpose
MTA-64 Adapter	for DiGiCo|Soundcraft|Studer|Harman MADl-TP variantNote: The MTA-64 uses the Extension port only for power, not for audio. The port is fed through on the MTA-64 and remains available for other extension boxes.

Please contact us for the scheduled availability of other break-out boxes.

Two multiverters can be connected together via the extension port when a larger number of different ports is required.

Note: Although this port makes use of a standard HDMI connector, it is NOT compatible with HDMI devices. Don't connect HDMI equipment! The HDMI connector was chosen because cables are ubiquitous and can easily be replaced (and also because the electrical characteristics are perfectly suited for this purpose).

3.7. MAD | optical

This port carries MADl data, according to the "optical" transmission method specified in AES10.

The yellow LED indicates the current status:

■Off: No incoming MAD data detected
■On: Incoming MAD detected, but no valid system clock
■Flashing: Incoming MADl and valid system clock detected

Control data e.g. for preamp control can be forwarded over this port. See 3.14, Control data forwarding for details.

Where possible, use the "MADl optical" connection rather than BNC or TP connections to reduce the chances of noise/interference and to increase reach.

3.8. MAD | BNC

This port carries MADl data according to the "coaxial" transmission method specified in AES10.

The yellow LED indicates the current status:

■Off: No incoming MAD data detected
■On: Incoming MAD detected, but no valid system clock
■Flashing: Incoming MADl and valid system clock detected

Control data (e.g. for preamp control) can be forwarded over this port. See 3.14, Control data forwarding for details.

3.9. MAD | TP

This port carries MADl data, according to the "MADl over Twisted Pair cabling" method specified in the draft for the upcoming AES10 standard (AES-X-213).

To interface to the DiGiCo or Soundcraft/ Studer/Harman variants of MADl-TP, an external MTA-64 adapter is required. See

The LEDs indicates the current status:

■Yellow: Link detected
■Green: Input data valid and system clock valid

This port can also be used as second AES50 port (adapter cable and altered setting required - see 9.2 Configuration settings, and 13.1 AES50/MAD|TP Pin swap adapter cable). This second port may be used either as standalone port (48ch) or in channel aggregation mode, meaning that both AES50 ports are treated as one single interface with the first port carrying channels 1-48|1-32 |1-24|1-16 @96kHz and the second port carries channels 49-64|33-64|25-32|17-32 @96kHz.

Control data (e.g. for preamp control) can be forwarded over this port. See 3.14, Control data forwarding for details.

3.10.AES50

This port carries Behringer|M|DAS compatible digital audio data (48ch @ 48kHz, 24ch @96kHz). It is also prepared to transmit control data from and to

Behringer|M|DAS preamps |i.e. for remote gain control}.*

The LEDs indicates the current status:

■Yellow: Link detected

■Green: Input data valid and system clock valid

To use more than 48|24 channels with AES50, the MAD|-TP port can be configured to work as second AES50 port. Use the channel-wise routing feature from the Web remote to map the channels as required.

This port can also be switched to work as second MADI-TP port (see 9.2 Configuration settings, and 13.1 AES50|MADI-TP Pin swap adapter cable). In MADI-TP mode, Control data (e.g. for preamp control) can be forwarded over this port. See 3.14, Control data forwarding for details.

3.11. Word clock

The wordclock input accepts a square wave signal in the frequency of the sample rate. x2 and x4 modes are automatically detected when the square wave has x2|x4 frequency, and can be manually set when the square wave has x1 frequency.

A 75 ohms termination resistor can internally be switched but is OFF by default. Altering the setting requires opening of the device, please contact us for further information.

The wordclock output is a square wave signal (50% duty cycle) and is able to drive up to two 75 ohm resistors in parallel. Its frequency is either identical to the sample rate or always x1 (see 9.2 Configuration settings).

3.12. Dante / AES 67

The "Primary" and "Secondary" ports are standard gigabit Ethernet ports, designed to connect to Dante Digital Audio Network. AES67 mode is alternative to Dante mode and can be set in the Dante Controller Software.

The Dante port provides also the Web UI and a telnet server (on port 2300) for remote control. Both services are available on the same IP address as the Dante audio interface | use the Dante Controller software to determine or change the |P|.

The port LEDs indicates the current status:

■Yellow: Link detected

■Green: Input data valid and system clock valid

Please refer to the Audinate website for information about Dante Technology, the latest Dante Controller drivers and related information.

By default, the ports are configured to act as switch (which allows daisy chaining), but can be changed using the Dante Controller Software as redundant ports for parallel connection.

3.13.M|D

The only command supported via the M|D| port is "Preset Recall". See 4.1 Preset Recall.

The yellow LED near the port flashes when incoming M|D| data is detected. All incoming data is forwarded to the M|D| THRU port, to allow daisy-chaining of devices.

Control data (e.g. for preamp control) can be forwarded over this port. See 3.14, Control data forwarding for details.

3.14. Control data forwarding

The multiverter is able to forward control data {headamp|stagebox control} between MADl ports, and from and to the M|Dl ports. The multiverter provides transparent forwarding of all extra AES3 bits |V|alid, |U|ser data and |C|hannel status, which makes it compatible to all vendor-specific remoting protocols.

To enable remoting, the channels containing the control data must be routed 1:1 (i.e. linearly), depending on the vendor protocol.

Vendor Control method
DiG|Co Control data	is contained in all bits (audio+user) of channel 57.To enable forwarding between different MADl ports,•Set MADl transmit mode of the involved MADl ports to 57ch(see 9.2 Configuration settings)•Route ch 57 to ch 57 both ways
Soundcraft Control data	data is contained in the 'U' bit of channels 1..10.•To enable forwarding between different MADl ports, route ch 1..10 to ch 1..10 both ways

Table 2: Remote control over MADI

4. PRESETS

All settings (excluding headphones level) can be individually stored in one of the 12 preset locations, and may be recalled at any time later. The settings are stored in non-volatile memory and are retained for years even if the device is switched off or the power cable is unplugged. Additionally, the settings can be downloaded via the Web UI, and restored on the same or a different device.

4.1. Preset Recall

▶Front panel

To recall a preset:

■Push the Recall button from the "Preset" menu.
■ Select the desired storage location ☑1 to ☑12 by turning the encoder left or right.
■Note: The presets "Test tone" and "Function" have special purposes.

See 9. Advanced Topics.

■Confirm the selected location by pushing the encoder, or push the

Back button to cancel the operation.

▶We b

From the "PRESET" menu, choose the desired preset number. An asterisk next to the number indicates that modifications to the recalled preset have been done. To save the modifications, choose "PRESET! Store".

Note: You can also upload presets from a file to the MVR. This is useful when transierring setups between different multiverters.

▶Command line

preset recall

▶M|D|

Preset recall is done via "Program Change" messages

(program 00 = Preset 1 ... program 11 = Preset 12).

The MD channel is set to 1 by default but can be altered using function "07".

(Note: The channel is a per-preset setting, if you need to change it you will need to do so in all 12 presets).

4.2. Preset Store

▶Front panel

To store a preset:

■Push the Store button in the "Preset" menu.

■ Select the desired storage location ☑1 to ☑12 by turning the encoder left or right.

■Confirm the selected location by pushing the encoder, or push the Back button to cancel the operation.

▶We b

Select 'PRESET / Store' menu to store the preset as current preset number, or ▼ select 'PRESET / Store as...' to choose a different number.

Note: You can also download presets to a file. This is useful when transferring setups between different multiverters.

▶Command line

preset store []

4.3. Changed presets

▶Front panel

When a preset is recalled, the corresponding location 1 to 12 is lit green. If any setting is changed afterwards (except for headphones level), the LED turns red to indicate that the current setting differs from the recalled preset. If you want your changes to be reflected also in the stored preset, just store the preset again. Otherwise, the changes are overwritten the next time a preset is recalled.

▶Web

A changed preset is indicated by an asterisk |*| next to the preset number. Use 'PRESET | Store' to permanently store changes into that preset.

▶Command line

A changed preset is indicated by an asterisk |*| next to the preset number. The current preset can be queried by calling preset without parameters.

4.4. Auto·Store

In addition to the presets stored in locations 1-12, the multiverter remembers always the current setting, even when power cycled or left unpowered for a long time. This means that you can always reset the multiverter and have the settings fully restored by switching it off and on.

5. ROUTING

Due to a lack of controls, the front panel allows only interface-wise routing. To use channel-wise routing (merging of different input streams), use either the web interface or the command line.

▶Front panel

The routing matrix indicates the interfaces between conversions are currently active.

■A green LED means that a connection is made between the two interfaces, and a conversion is currently in progress.
■A red LED means that a connection is made, but inactive because the input or clock signals are missing.
■A yellow LED means that a test tone is currently output instead of the input signal.

Routing is easy if you think this way: "I want this input mapped to this output"

To make or break a connection in the Routing matrix:

■Push the Set button in the "Routing" menu

■A yellow blinking cursor indicates the current position within the matrix. Move it by turning the encoder to the desired point where you want to make or break a connection.
■At the beginning or end of the line, continue to turn to the right to make the cursor wrap around to the previous or next line.
■ Push the encoder or press the Set button to make break a connection. When the cursor blinks yellow/red or yellow/green, the connection has been made; when the cursor blinks yellow/dark, the connection was broken.
■ To exit the routing matrix, push the Back button.

▶We b

The web interface allows fine-grained routing control in different levels (whole interfaces, channel groups or single channels). Routes can be entered via either Matrix or List view (both can be used interchangeably, and routings established in one view show immediately up also in the other).

Matrix view: ideal for quick routings, everything on one glance. The arrangement is the same as on the front panel

■Click anywhere in the matrix to make or break a connection. Multiple connections can be made by click-and-drag, broken by holding SHIFT.
■Current status of a connection is indicated by the large colored icon on the connection; current status of each input / output is indicated smaller on the header.
■ The matrix can be expanded to group- and channel-wise views via + and buttons on rows [inputs], columns [outputs] or intersections (connections).
■ The "Expand" and 'Collapse" buttons zoom the entire matrix. Use the 'Optimal' button to expand to all sub-routings.
■To clear all connections, click 'Delete All'.

List view: quick way to establish complex routings

■ Each routing can be entered as text line, in the form "Source > Sink" or alternatively "Sink < Source" (both produce identical results).
■ "Sink" and 'Source' can be entire interfaces, channel ranges or single channels. Entire interfaces are be specified as two-letter abbreviation (i.e. "MO" for MAD optical)
■Channel ranges can be specified by appending a colon, followed by the start and end channels.. For example, Dante channel 9 to 16 would read "DA:9-16"
■Single channels are specified by appending a single the channel number to an interface, separated by a colon. For example, AES50 channel 24 would read 'AE:24'
■Example 1: to route all channels from AES50 to MADl coaxial, enter 'AE > MC" (or alternatively, "MC < AE")
■Example 2: to route channels Dante 56-64 to ADAT channels 1-8, enter 'DA:56-64 > AD:1-8" (or alternatively, "AD:1-8 < DA:56-64")
■Example 3: to route MAD | TP channel 2 to Extension channel1 | 1: 'MT:2 > EX:1' | or alternatively, "EX:1 < MT:2"

▶Command line

route []

with and indicating channel ranges as described in the "List view" section above. If is omitted, the current source for is printed.

6. CLOCKING

All components within a digital audio system must reference to the same master clock to ensure that they run synchronously. The multiverter can use any of the incoming interfaces as clock source, or alternatively it can act as clock master using its internal, high-quality clock synthesizer.

If a common clock is not possible (e.g. when incoming data has a different sample rate), the optional ASRC module can be used to convert the data to the multiverter's main clock.

See the ASRC manual for details.

6.1. ClockShield

The multiverter's unique ClockShield feature allows the device to run up to one second (!) without a master clock signal. This makes the multiverter very robust against disturbances, glitches and dropouts in the clocking system.

How it works:

■When the clock signal is lost, the multiverter's clock continues to run for up to one second, at the frequency which it has been locked to when the clock was valid. During that period, audio processing continues as before.
■When the clock signal is re-applied, re-synchronization takes place to ensure perfect bit-wise alignment of data and clock. To avoid pops and clicks, all audio signals are soft-muted before the re-sync happens, and are soft unmuted directly after re-sync. The whole process takes only a few milliseconds and produces only minimal artifacts, often not even audible.

ClockShield is supported on all interfaces, but works best when the multiverter is clocked from the BNC wordclock input.

6.2. Clock source selection

▶Front panel

To set the main clock source:

■Push the Set button in the "Clock" menu.
■Move the yellow blinking cursor to the desired clock source.
■ Push the encoder or press the Set button to select the interface, or press Back to cancel.
■Depending on the selection, you will be asked to provide additional information:
■ When the clock source is set to internal ☑|NT| you will be asked for the sample frequency where the internal clock should run at. Choose one from the 32kHz to 192kHz, or press Back to return to the clock source selection. NOTE: Not all sample rates (especially the 32/64/128kHz modes) are available on all interfaces.
■ When MADl optical ☑ M0, MADl coaxial ☑ MC, MADl-TP ☑ MT or BNC wordclock ☑ WCLK is chosen, you need to set whether the multivertor should run in x1 {32|44.1|48kHz}, in x2 {64|88.2|96kHz} or in x4 {128|176.4|192kHz}. Choose the desired mode and push the encoder to confirm, or press return to the clock source selection.

Note: Regardless of the selection, the multiverter will always run in x2 mode when MAD196k frames are received.

▶We b

The main clock parameters can be configured on the 'CLOCK' page. When the ASRC module is installed, its behavior (asynchronous interfaces etc.) can be selected in the ASRC section on the bottom.

6.3. Dante Clock

The Dante network itself needs one device which acts as "Network clock master" (not to be confused with the system clock master, which may also be a different device!)

The selection of the network clock master can be done in the Dante Controller software, and must be done depending on the multiverters' main clock source:

multiverter clock source|set on multiverter|	Dante network clock master(set in Dante controller software)
Dante module *DA	any Dante node |except Dante Virtual Soundcard|
all other sources only multiverter possible

Table 3: Dante clocking modes

7. PANEL LOCK

▶Front panel

The panel lock feature can be used to disable all buttons on the front panel. This can be used to protect the MVR-64 against undesired or accidental parameter changes. The panel lock feature is available from firmware version 1.4 and higher.

■ To lock the panel, hold down the Back button while pushing the encoder. The seven-segment display will blink to indicate the now locked panel. All buttons on the front panel are now disabled.
If a button is pressed while the panel is locked, the seven-segment display will blink to indicate the locked panel.
■ To unlock the panel, hold down the Back button while pushing the encoder.

8. MONITOR

The "Monitor" section controls the headphone amplifier which allows you to listen to any channel received on the inputs.

You can adjust if mono (same channel on both ears) or stereo signals are output on the headphones. Also, extra gain

(+6|+12|+24dB| can be added for the headphones output to ease monitoring of silent signals (but may cause clipping at larger levels).

To adjust these settings, see 9.2. Configuration settings

▶Front panel

To select a particular input to listen to:

■Press the Set button in the "Monitor" menu.

■Move the yellow blinking cursor to the desired interface.

■ Push the encoder or press the Set button to select the interface, or press Back to cancel.

To select a channel:

■ Make sure that ⚙Ch mode is selected. If not, push the encoder once.

■Rotate the encoder left to decrease the channel, or right to increase the channel. In stereo mode, the selected channel is output on "L" whereas the subsequent channel is output on "R".

To change the volume:

■ Make sure that ☑ Vol mode is selected. If not, push the encoder once.

■Rotate the encoder left to decrease the volume, or right to increase the volume.

▶We b

The "MONITOR" page allows to set the source interface, channel and volume for the headphones. More settings [stereo:mono mode, gain] can be found on the "SETTINGS" page.

▶Command line

monitor [:]

Sets the source interface and channel. If stereo monitoring is selected, corresponds to the 'L' channel, the subsequent channel is output as 'R' signal.

volume [|+|-]

Sets the volume of the monitor output, either as from 0-99, or '+' to increment ! "-" to decrement the volume by 1.

9. ADVANCED TOPICS

9.1. Test tone mode

▶Front panel only

For diagnostic purposes, the multivertor is able to play a test tone (1kHz, -20dB sine wave) on all outputs which are currently active. This feature is especially helpful to determine problems in your signal flow, as it does not rely on any external sources [except for the clock].

To enter test tone mode:

■Push the blue Recall button

■ Move the cursor to ☀ Test tone by turning the encoder left or right

■ Confirm your selection by pushing the encoder, or push Back to cancel the operation.

■The test tone mode is now active. All outputs which are active in the Routing matrix are replaced by the test tone signal indicated by yellow lit LEDs in the Routing area.

To exit testione mode:

■Push the blue Recall button

■Move the cursor to "Test tone" by turning the encoder left or right

■ De-select Test tone mode by pushing the encoder, or push Back to cancel the operation.

9.2. Configuration settings

The multiverter offers fine-tuning of various parameters and seldom used settings via the "Function" item in the Preset menu, or via the web interface. The "index" indicates the parameter to change, while the corresponding "value" reflects its current setting. A complete list of "index/value" pairs can be found in the table below.

▶Front panel

The "function index" is indicated by ☑1 to ☑12 in the "Preset" menu, while the corresponding "value" is displayed in the 7-segment display.

To adjust a particular setting:

■Push the blue Recall button

■ Move the cursor to Function by turning the encoder left or right

■ Confirm by pushing the encoder (or push Back to cancel the operation).

■The Function LED should now be lit.

■ Move the cursor to the desired index ☉1 to ☉12

■ Confirm by pushing the encoder (or push ▶Back to cancel the operation)
■The current value is displayed in the 7-segment display. Rotate the encoder to change the value, and push it to confirm.

▶Web

The 'SETTINGS' page contains various fine-tuning parameters.

9.3. Audio Interface self-test

The MVR-64 can check itself for correct operation. This is done by sending a special signal out on every interface through an external loop back and monitor the received data for correctness. When the received data is correct, the respective LED on the front panel turns green.

To perform the self-test,

■ Connect the cables in loop-back mode as shown below
NOTE: If you want to test a specific interface only, it is sufficient to wire the loop-back on that interface only and monitor the respective LED
■ Enterself-test mode by pushing Recall move to Function confirm with

To verify correct operation of all LEDs and buttons,

■ Enter LED button test mode by pushing Recall move to Function confirm with OK move to 11 push OK turn encoder until display shows "02" and confirm with OK
■During the test, all front-panel LEDs show the same color. Each button press cycles the color, and Back exits the test. The seven-segment display shows 88 and 8 alternatively.
■The LEDs on the back are constantly lit during the test, except for the Dante LEDs which maintain normal operation.

9.5. ASRC self-test

The SRC-64 sample rate converter can be self-tested for correct operation. A 1kHz, 96k sine wave is passed through all channels of the ASRC (down-sampled to 88.2k), and looped back (up-sampled to 96k again).

The result can be listened to on the headphones and is also present on MAD optical (ch 1-32) and MAD coaxial (ch 33-64).

■ Enter ASRC self-test mode by pushing Recall move to Function confirm with OK move to 11 push OK turn encoder until display shows 03 and confirm with OK
■Plug in headphones. Turn the encoder and listen carefully to channels 1 to 64, one after another. On all channels a clean 1 kHz tone should be audible.
■ Press ↩ Back to exit the test.

10. FIRMWARE

10.1. Version check

We recommend to check the firmware via the Web interface ['ABOUT' tab]. Only there is the overall version number |= package version, same as in the file name of the firmware ZIP-file visible. Else you will see only component sub-versions.

▶Frontpanel

Push Recall move to Function confirm with OK move to 12 push OK The different versions are shown in the 7-segment display according to Table 4: Configuration settings, index 12.

NOTE: This lists only the component sub-versions and not the overall firmware version.

NOTE: This lists only the component sub-versions and not the overall firmware version.

10.2. Upgrade

Firmware upgrade involves two operations which must be both carried out (order doesn't matter):

1) FPGA|Frontpanel{via USB and command line tool}

2) Dante upgrade (via Dante network connection)

1. The FPGA and Control firmware is updated via the USB port.

Connect the MVR-64 via USB to your PC and run

MVR-64-Updater.bat | on Windows

or sudo ./MVR-64-Updater.sh (on Linux)

and follow the instructions on the screen.

Mac users: The updater runs also in a bootcamp Windows session, when both

COM ports are mapped to windows.

1. The Dante firmware is updated using the Dante Firmware Update Manager

[available for Windows and Mac]. The MVR must be connected to the Danie network. Select 'Update Firmware' and choose the

13. ACCESSORIES

13.1. AES50/MADl-TP Pin swap adapter cable

The AES50 and MAD|-TP ports have different pin-outs as required by the respective standards. AES50 uses Pins 1:2 and 3:6 for the signal, 4:5 and 7:8 for sync, while a MAD|-TP port uses 4:5 and 7:8 for the signal (with pins 1:2 and 3:6 reserved - this is where the AES50 sync signal is connected to in the multiverter). To use the alternate function of such a port, an adapter cable with the pinout shown below is required:

Illustration 1: AES50|MAD|.TP swap cable

13.2. MTA·64 Adapter for MADI·TP

With the MTA·64, the becomes capable of Twisted Pair variants used in DiGiCo and

connecting to the MADI-TP | MADI over Soundcraft | Studer | Harman desks. It's connected between the MVR-64's MADI-TP port and the console or stagebox and adapts signal levels and pin-outs.

What's more: you don't need any special crossover cables thanks to internal MDIX logic - any standard 1:1 Cat5 cable will do, no matter if you want to connect to your console or the stagebox.

13.3. SRC·64 Asynchronous Samplerate Converter Module [optional hardware]

The SRC-64 add-on module - available as separate hardware - adds the capability of asynchronous sample rate conversion to your multivertier. Designed as internal

3D rendering of a green printed circuit board with various electronic components and connectors (no visible text or symbols)

add-on module, it leaves the 'Extension' port available to other break-out boxes. | Note: The module is called 'ASRC" in this manual for clarity). It features highest analog performance | THD+N -134dB typ. | , 64-channel, bi-directional conversion between any interfaces supported by the multiverter plus a number of special modes for maximum flexibility. The ASRC can be

assigned to any input interface and also any output of the multiverter, giving a true bi-directional conversion between both clock domains:

■The ASRC is inserted (by software) between the selected input and the rest of the multiverter. The input can run independently, and the ASRC takes care of matching the data to the main clock of the multiverter.
■For the output, the ASRC can be inserted between the main clock of the multiverter and the selected output. The data is then converted to match the ASRC's asynchronous clock ("async clock") and sample rate before it is sent out.
■ Existing multiverter routing capabilities are fully preserved.
■Special modes allow the use of two MADl or AES50 ports together, to send and receive all 64 channels at 96 kHz |48ch for AES50|. Conversions between MADl 64ch @96k => MADl 64ch @48k or vice versa - using two MADl ports for the 96k part and one for the 48k part - are also supported.
