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.

20 Inputs and 20 Outputs To Handle the Biggest Sessions
With (8) XLR/TRS inputs, (2) TRS inputs, multi-channel digital inputs via S/PDIF coaxial, and optical digital connectors, the US-20x20 provides a total of twenty simultaneous inputs  when operating at 44.1kHz or 48kHz. Twenty simultaneous outputs are also transmitted from your DAW  at 44.1kHz or 48kHz utilizing the (10) TRS line outputs, S/PDIF coaxial and optical digital outputs. The ADAT optical input/output support SMUX2 and SMUX4 - required for high sampling rates. Using (2) US-20x20 and the optical digital connections, it is possible to configure a (16) microphone recording system.

[Note] When operating at 88.2kHz or 96Khz, up to (16) inputs and (16) outputs are possible.
[Note] When operating at 176.4kHz or 192Khz, up to (12) inputs and (12) outputs are possible.

Eight Ultra-HDDA Mic Preamps with 20dB of headroom
Ultra-HDDA (High Definition Discrete Architecture) mic preamps, an original Tascam design, use discrete construction for superior audio quality. Tascam has achieved an EIN rating of -125 dBu (EIN is a value measurement of the absence of noise). The preamps have over 20dB of headroom, well above competing interfaces. This headroom is especially helpful on high SPL sources like drums and guitars.

8 XLR/TRS inputs and 2 TRS inputs
The 8 XLR/TRS mic inputs have switchable +48V phantom power in banks of 4, making it possible to use 8 condenser mics at the same time. The 2 balanced line inputs on the rear of the unit are switchable between -10dBV and +4dBu. The user is able to interface an instrument of any level - balanced or unbalanced.

Direct Inputs for Guitar and Bass
Two instrument-level inputs are provided for direct input of guitar or bass. Make the most of guitar effect plug-ins, such as the TH2 effect that is included with Cakewalk SONAR.

Mic Preamp Mode enabling use as a mic pre with analog & digital output
Mic Preamp Mode enables the use of the product as a standalone mic pre. In this mode, the XLR/TRS signal from the from panel flows through the Ultra-HDDA mic preamp, and is output through the TRS jack and the digital output on the rear panel. This is perfect for use into a mixer for live performances. It is not necessary to connect the interface to a personal computer via USB.

Mixer mode enabling use for PA/SR and use as a keyboard mixer
Utilizing a 32-bit processing DSP mixer, the product can be used as a 6-bus mixer for PA/SR. In mixer mode, the US-20x20 provides an output patch bay and reverb effect. In mixer mode, the product is connected to a computer and the mixer is controlled from the computer. When (2) US-20x20 are connected, the result is a (16) channel digital mixer useful for live performances. In digital mixer mode, the motion of solo button provides "pre-fader-listen (PFL)".

Advanced DSP mixer with EQ and compression on each channel
An obstacle with computer-based recording is latency (delayed audio signals). New USB 3.0 driver software has been developed to eliminate latency issues and driver set-up problems. In addition, the built-in mixer provides near-zero latency monitoring while recording. It utilizes the high-performance Dual Core BlackFin DSP making it possible to offer 4-band EQ and compression on each channel. A stereo reverb is also provided for great-sounding headphone mixes.

Class-compliant Drivers Support iPads and other Tablets
You will not need another audio interface if you decide you want to make music using an iPad or other iOS device. The performance of these interfaces has been tested with major DAWs - you can continue to use them even if you change DAW software. Since these units include MIDI inputs and outputs, they can also be used as MIDI interfaces.
