Continuing the legacy of RME s famous HDSP Digiface, a triple ADAT I/O interface with phones and PCI interface, Digiface USB simplifies connection with USB 2, does not need an external power supply, and even adds another optical I/O, resulting in 32 channels input and output each when using ADAT optical. The analog output hosts channels 33/34, and can be used freely thanks to TotalMix FX, RME s routing and monitoring solution that knows nearly no limits in routing and mixing (the Digiface USB does not include FX). Each single optical port can use either ADAT (up to 8 channels) or SPDIF (stereo).
While the inputs adapt automatically to the received signal format, the outputs can be individually switched between ADAT and SPDIF operation.
