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.

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).

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
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's on-board DSP, mixing, and device settings from the web app software running in your favorite web browser on the computer, or even a tablet or smartphone on the same Wi-Fi network as your computer.
