US-20x20 Celesonic
USB3.0 Audio MIDI Interface with Mic Pre/Mixer
TASCAM’ 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.
This model has been discontinued in North, Central and South America. Please check the availability with your local distributors in other areas.

FAQs
Download and install firmware version 1.01 or later for your device from the downloads page.
This is fixed in settings panel version 1.01 or later. It's a free update on the downloads page.
As of this writing, USB 3 only works on the Windows 10 OS. TASCAM is using a class-complient driver, which means that we have no control over bug fixes in the OS. Apple is working on this issue and is hoping to fix it in an upcoming update to OSX 10.11 El Capitan. Please note that there is no reduced feature set when working in USB 2 mode, including channel count and latency.
Make sure that the "Auto Power Save" switch on the rear panel is set to off. It is set to on by default (for CE complience.)
You need to connect the US-20x20 to a computer to set clocking, sample rate, and other settings – even in mic preamp mode. Open the US-20x20 Settings Panel application to change this.
Depending on the usage environment, reboot the interface by turning the power off/on again, or disconnect and reconnect the USB cable.
Your device's playback application/software, and playback file frequencies (sampling frequency) may not be matching. Set the frequencies of the playback file and each configuration to be the same, or unify the frequencies of the playback file.
