USB Audio MIDI Interface with Mic Pre/Mixer


TASCAM’s Celesonic US-20x20 packs 20 channels of analog and digital I/O into a single rackspace with great sounding preamps and USB 3.0/2.0 connectivity. Eight Ultra-HDDA microphone preamps provide 56dB of gain and high headroom to make microphones sound their best. Up to ten channels of digital I/O are included on ADAT and S/PDIF connectors, with word clock also provided for use with external clocks like TASCAM’s CG-1000. MIDI I/O allows use with controllers and synthesizers, and sample rates up to 192kHz/24-bit are supported.


The TASCAM Celesonic US-20x20 is the first USB 3.0 interface to use class-compliant drivers for future-proof use with computers and tablets. A built-in DSP mixer includes parametric EQ and compression on every channel and a stereo reverb send for great-sounding monitor mixes. The DSP mixer can also be used as a live mixer or submixer with computer control. The US-20x20 has three operation modes – audio interface, digital mixer, and 8-channel digital mic preamp –for maximum flexibility.
