The most popular TASCAM 4-channel USB audio interface has been updated with better audio specs and a fresh new look for the US-144mkII. The US-144mkII starts with two great-quality XLR microphone preamps with phantom power for condenser microphones. There's also a pair of balanced line inputs and a guitar-level in for direct recording of electric guitar or bass. A pair of S/PDIF digital inputs and outputs is also included, for a total of four inputs and outputs at up to 96kHz/24-bit audio quality.
