The universal format converter: Everything in 1U!

For all your digital audio needs:
This unique piece of hardware is able to convert between an impressive selection of digital interfaces - any to any, all at once.
Supported Audio Interfaces
  • ADAT (8x), SPDIF/AES3 optical
  • MADI optical
  • MADI coaxial
  • MADI-TP (up to 2 ports)
  • AES50 (up to 2 ports)
  • Dante / AES67
  • and many more via breakout boxes (currently planned: Waves Soundgrid, AVB, AES3)
Key features
  • 64x64 channels on each interface with channel-wise routing/splitting between interfaces
  • Integrated headphone amp
  • Asynchronous sample rate conversion (plug-in module)
  • Fully remote-controllable via web, telnet and USB.  Run Live Demo
  • Extensible to future interfaces via break-out boxes


What the multiverter can do for you:

  • Interface your recording gear to any signal source
  • Make your production truck or OB van compatible to anything
  • Use your ethernet port as 64x64 recording interface with the Dante® Virtual Soundcard technology
  • Sample-rate convert between any interfaces using the SRC-64 plugin module
  • Send and receive low-latency, 64x64 audio over your standard ethernet network
  • Bring your legacy gear up to date
  • ...and anything else you can imagine!
