The rack-mountable TAC-8 audio interface is designed to act as the central hub in both professional and home environments. It provides 8 analog inputs and 10 analog outputs, 10 digital inputs and outputs (in both S/PDIF and ADAT Optical formats), and both Word Clock and MIDI I/O.

Whether you want to record large scale multi-channel 24-bit/192 kHz sessions in your studio without worrying about latency or you want to bring your onstage performance to new heights, the TAC-8 allows you to take full advantage of today's latest technology.
