The Appsys MVR-MKII Multiverter is an evolution of the versatile MVR-mkII format converter, meticulously designed to meet all your digital audio needs. This unique piece of hardware stands out for its ability to convert between various digital audio interfaces, regardless of format, all at once. The MVR-MKII is packed with features such as per-channel routing, an easy-to-use web interface, sample rate conversion, remote headphone control and much more. And, even more exciting, for users of the MVR-64 (older model), all the firmware features of the new model can also be ported across, as long as the hardware allows it.

What the Multiverter can do

• Connect your recording equipment to any signal source
• Make your production truck or OB van compatible with any input signal and clock
• Sample rate conversion between any interfaces using the SRC-64 plugin module
• Connect different Dante networks with optional sample rate conversion (up to 64ch 96k <> 48k bidirectional)
• Use your ethernet port as a recording interface with Dante® Virtual Soundcard technology
• Record from any source, and directly from MIDAS®/Behringer® stage boxes with remote headamp control
• Upgrade your older equipment

-...and any other audio routing or conversion task you can imagine!

Specifications

Each AC input: 85..264VAC, 50-60Hz,

0.75A@115VAC / 0.5A@230VAC

DC input: 9-18VDC (up to 30V

tolerant), 2.5A peak

352x352 (up to 32x32 per

interface) in x2 modes

176x176 (up to 16x16 per interface) in x4 modes

Multiple conversions (i.e. Dante ⬄ MADI and ADAT ⬄ AES50), each using

the total number of channels, can run simultaneously.

+/-100ppm

Variable speed operation is not supported

(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 must be

chosen according to the network topology, and can vary from

150µs to 5ms.

Each port can alternatively be used as an optical SPDIF or AES3 port with 2 channels
