TASCAM’s US-4x4 combines great audio quality and ergonomic design for a powerful 4-in/4-out USB 2 audio interface.

Four of TASCAM’s Ultra-HDDA mic/line preamps provide up to 57dB of gain with nearly inaudible noise and distortion specs. The audio design features high-performance, musical components like NE5532 op amps for rich sound quality without coloring the source.

The US-4x4 includes class-compliant drivers for plug-and-play operation on Mac OSX and iOS devices like the iPad, and a simple driver adds ASIO compatibility for Windows. MIDI in and out are also included for connecting synths, drum machines, and controllers. The interface includes two DAW applications to choose from – both Cakewalk SONAR X3 LE and Abelton Live Lite 9.

With solid audio specs, iOS compatibility, and an easy-to-read angled design, the US-4x4 is the ultimate 4-channel interface for home, project, and mobile studios.
