  • Page 5 MVR-64 This device is intended to be used in a professional environment with restricted access only. Thank you for purchasing one of the most innovative digital audio converters on the market. The multiverter was designed with true vendor independence and interoperability in mind, with the idea to make all your gear interact seamlessly.
  • Page 7 MVR-64 The multiverter is a unique device which allows you to convert digital audio data in any direction between the most popular formats: (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.

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.
  • Page 13 MVR-64 The ports are mapped to the channels as shown in the table below. Please note that SPDIF/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.
  • Page 14 User's Manual 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): MTA-64 Adapter for DiGiCo/Soundcraft/Studer/Harman MADI-TP variant Note: 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.

  • Page 21 MVR-64 In addition to the presets stored in locations 1-12, the multiverter remembers 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.
  • Page 22 User's Manual 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 The routing matrix indicates the interfaces between conversions are currently active.

  • Page 31 MVR-64 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).
