This is a rare modular matrix digital audio switcher made by FCP Friendchip and loaded with eight 4 in 4 out Toslink/ADAT modules. I am the original owner and used it for many years before migrating most of my studio from ADAT to MADI.
The switcher routes any input to any output using a 32 x 32 Matrix. It will not split out the individual channels of a given ADAT input. It can route a given ADAT input to multiple outputs simultaneously. It works by connecting any of the 32 inputs to any of the 32 outputs thus providing the capability to route any of the 256 possible audio inputs to 256 possible audio outputs in groups of eight (or 4 for 96khz operation).

It is remote controllable over MIDI using the included remote software (see pic). I have not tested the software under Windows 11 but I know it worked under windows 10 and previous Windows OS.

The unit can also be managed entirely from the front panel if you so choose and includes memory for up to 99 presets.

Hoping to find a good home for this - It is incredibly useful in an environment that has a lot of Toslink/ADAT to manage.
