The Appsys MVR-MKII Multiverter is an evolution of the versatile format converter, MVR-mkII, meticulously engineered to cater to all your digital audio needs. This singular piece of hardware stands out with its ability to convert between various digital audio interfaces, regardless of format, all at once. The MVR-MKII is loaded with features such as channel-wise-routing, a user-friendly web interface, sample rate conversion, headamp remote control, and much more. Excitingly, for MVR-64 (old model) users, all firmware features of the new model will also be back-ported as long as the hardware allows it!

What the Multiverter can do

  • Interface your recording gear to any signal source
  • Make your production truck or OB van compatible with any incoming signal and clock
  • Sample-rate convert between any interfaces using the SRC-64 plugin module
  • Bridge different Dante networks with optional sample rate conversion (up to 64ch 96k <> 48k bidirectional)
  • Utilize your ethernet port as a recording interface with the Dante® Virtual Soundcard technology
  • Record from any source, and directly from MIDAS®/Behringer® stageboxes with remote headamp control
  • Bring your legacy gear up to date
  • ...and any other audio routing or conversion task you can imagine!


Key Features

  • 704x704 channels routing matrix with channel-wise routing/splitting between interfaces
  • Bi-directional sample rate conversion up to 128 channels using the  SRC-64 plug-in module
  • Fully remote-controllable via Web, Web-over-USB and command line (telnet/UART)  Web Remote Demo
  • Headamp remote control for MIDAS®/Behringer® stageboxes
  • Integrated headphone amp to monitor any incoming signal

Audio Interfaces

  • AES3 (16x16ch)
  • ADAT (4x), SPDIF/AES3 optical
  • MADI SFP (2x), supports  Ferrofish SFP Coax
  • MADI coaxial
  • AES50 (up to 2 ports)
  • MADI-TP (up to 2 ports)

Other things to mention

  • Preset store/recall (16 different setups)
  • Jumperable pinout for AES3 (Tascam/Yamaha) and AES50/MADI-TP ports
  • Test tone generator simplifies troubleshooting of complex setups
  • Triple-redundant power supply (2x 90-240VAC, 1x 9-18VDC)
  • Can be powered alone from industry standard 4-pin XLR plug battery packs
  • Separate network control port
  • MIDI and RS485 embedding/de-embedding from MIDI/RS485 jacks into MADI streams (RME™/DirectOut™-compatible)
  • Transparent forwarding of MADI control data (i.e. headamp control, MIDI over MADI)

Latency The table below shows the overall latency (receive+convert+transmit) between the various interfaces in number of samples.
For x1 modes (32/44.1/48kHz), n is 1.
For x2 modes (64/88.2/96kHz), n is 2.
For x4 modes (128/176.4/192kHz), n is 4.
The Dante latency d depends on the setting in the Dante controller which should be chosen according to the network topology, and can range from 150µs to 5ms.
