Introducing the

MADI / USB / AVB-TSN Ethernet audio interface with DSP and mixing

The M64 is a flexible MADI interface, router, repeater, splitter, converter and mixer with AVB/TSN networking. It is ideal for routing MADI digital audio streams in live performance systems, network installations or recording studios of any size.

256 channels of MADI I/O

The M64 delivers optical MADI (64 channels in and out), plus independent coaxial MADI (64 channels in and out) with an extra duplicate BNC output, in all standard formats and sample rates.

High-performance

computer connectivity

New, optimized drivers for both Mac and PC deliver ultra-low latency performance. With a high-performance DAW such as Digital Performer, the M64 delivers an astonishing round trip latency (RTL) of 1.70 ms (milliseconds) on OS X and 1.71 ms on Windows over USB (at 96 kHz with a 32-sample host buffer).
1.7 ms of latency

USB 2 audio class compliant
USB 3 and iOS compatible

The ultimate MADI

converter, router, splitter and repeater

Send any input to any output, or split to multiple output channels. Convert optical MADI to coaxial MADI. Route MADI streams to and from the computer, plus any devices on the AVB/TSN network.

DSP mixing and effects processing

The M64's 48-input digital mixer delivers 7 stereo aux busses, 3 groups, access to 64 network inputs, and DSP effects, including classic reverb, EQ modeled after British analog console EQs and compression modeled after the legendary LA-2A compressor. If you know your way around a large-format mixing console, you'll feel right at home. With 32-bit floating point processing, the M64's DSP engine delivers virtually unlimited headroom and the utmost in sound quality.

Stand-alone operation with wireless control

Connect an Apple® Airport™ or other Wi-Fi router with a standard Ethernet cable for wireless control of device settings, powerful 48-channel mixing and DSP effects.

Web app control from any device

Control everything from your laptop, tablet and smartphone

The software that you use to control the M64 doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the M64 on-board DSP, mixing, device settings, and network audio routing from your favorite web browser on a laptop, tablet or smartphone connected by wire or Wi-Fi to your local area network. Use any web client on any platform - Mac, Windows, Linux, iOS, Android - as long as it shares the same network.
