Continuing our legacy and passion for audio, the US-20x20 (twenty-by-twenty) “Celesonic” 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.
Our original Ultra-HDDA mic preamps allow you to input high-quality audio from any audio source just by turning a knob. These are the same mic preamps that are in our HS-P82 professional recorders, which are popular in the broadcast and film industry. These versatile preamps can handle both condenser and dynamic mics, and will allow you to enjoy high-quality recording even if you are not an expert. These versatile preamps also feature line-level inputs for keyboards and other equipment.
With eight XLR/TRS inputs, two TRS inputs, multi-channel digital inputs via S/PDIF coaxial, and optical digital connectors, a total of 20 simultaneous inputs is possible when operating at 44.1 kHz or 48 kHz. As with the inputs, 20 simultaneous outputs is possible at 44.1 kHz or 48 kHz utilizing the ten TRS outputs, S/PDIF coaxial and optical digital outputs. The optical input/output support S/MUX2 and S/MUX4 - required for high sampling rates. Using two US-20x20 and the optical digital connections, it is possible to configure a 16-microphone recording system.
Note: When operating at 88.2 kHz or 96 kHz, up to 16 inputs and 16 outputs are possible. When operating at 176.4 kHz or 192 kHz, up to 12 inputs and 12 outputs are possible.
The versatile US-20x20 is an Interface for multitrack recording using a personal computer and DAW, a standalone mic preamp, or a mixer for live performances.
An obstacle with computer-based recording is latency (delayed audio signals). New driver software has been developed to eliminate latency issues and driver setup problems. The built-in mixer utilizes the high-performance Dual Core BlackFin DSP making it possible to offer 4-band EQ and compression on each channel.
Note: When operating at 176.4 kHz or 192 kHz, the effects (EQ, compression, phase and reverb) of the DSP mixer cannot be used.
USB 3.0 is used in the US-20x20 for 24-channel transmission at 192 kHz/24-bit. This is not possible with USB 2.0.
| Supported USB version | Operating system |
|---|---|
| USB 3.0 / USB 2.0 | Windows 10 |
| USB 2.0 | Windows 8, Windows 7, OS X Yosemite (10.10), OS X Mavericks (10.9), OS X Mountain Lion (10.8) |
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.
You can either utilize the brackets for rackmount installations or unscrew the brackets with the hex keys provided when using on a desktop.
