Support for TOSLink

Each optical input or output is individually switchable to stereo TOSLink (optical S/PDIF), regardless of the current sample rate setting (from 44.1 to 96 kHz).

Flexible router, converter and splitter

Send any input to any output, or split to multiple output channels. Convert any format to any other (Optical, AVB-TSN and USB). Includes routing to and from the computer, plus any devices on the AVB-TSN network.

Stand-alone operation with wireless control

Connect a standard Wi-Fi router with a standard Ethernet cable for wireless control of device settings, routing/splitting, powerful 48-channel mixing and DSP effects.

DSP mixing and effects processing

Flexible 48-input digital mixer with 7 stereo aux busses, 3 stereo groups, access to 32 network inputs, and DSP effects, including reverb, 4-band EQ, gate and compression.

*After a ten-year run, Windows 7 has been officially end-of-lifed (EOL) by Microsoft as of January 4, 2020. Therefore, MOTU products no longer officially support Windows 7, although existing installed products (as of June 2020) should still continue to function as they have been under Windows 7. However, future updates, including drivers, may require Windows 8 or later.
