MOTU M64 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.

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).
