Continuing our legacy and passion for audio, the US-20x20 (twenty-by-twenty) is the flagship of the Tascam line of interfaces. Designed
for use in professional recording facilities or project studios, this audio interface supports 192 kHz and utilizes USB 3.0, a leading-edge
transmission standard. With added features such as Mic Preamp Mode and Mixer Mode, it becomes a very versatile tool – along with being an
interface for multi-channel recording.

Microphone preamplifiers are crucial for highest audio quality. The eight Tascam Ultra-HDDA mic preamps have an equivalent input noise (EIN)
of –125 dBu. And 20 dB of headroom on the microphone and line inputs allow to easily handle high SPL transients from percussion and instruments.

Utilizing a high-performance Blackfin processor, the US-20x20 offers an advanced DSP mixer including EQ, compression and reverb effects on
each channel. The processor not only excels on the dynamics and effects, but enables multi-channel transmission via USB 3.0 for the studio.

Additional significant features enable the seamless workflow of the professional engineer. Mode switching provides the options of using the
US-20x20 as a standalone mic preamp, an audio interface, or as a mixer for sound reinforcement applications.

Complete connectivity to various types of audio equipment is achieved by utilizing the analogue inputs and outputs, digital input and output
via coaxial and optical connectors, MIDI, and word clock BNC connectors.



The radical eye-catching style and angled industrial design of the US-20x20 make desktop recording a breeze. A rack-mount adapter is also included.

On the DA side of things nothing new to get excited about their specs remind me of 1998.

 

That and there pre-amps still suck Tascam is very cheap on Quality to this day, only thing decent they use to make was the Reel to Reel players yrs ago!, oh shit 1998 your right

 

Get a Foucsrite pro 40 I did and I am very happy with it.

 

USB 3.0 is a marketing gimmick, nothing more.
