Tascam US-100

The US-100 is a simple yet high-quality USB 2.0 audio interface perfect for people getting started with recording. It features a microphone input as well as instrument level input for direct recording guitar or bass. Stereo line inputs are provided, and can be switched to phono-level to connect a favorite turntable to digitize a vinyl collection. All of this is housed in a solid aluminum chassis to withstand daily use from the road to the dorm room.

As a 48-kHz/16-bit stereo audio interface, the US-100 connects to and is powered by a Mac or Windows computer using USB 2.0. It offers a 3.5-mm stereo headphone output and zero-latency input monitoring as well as a separate control to adjust the balance between audio input and computer sound. A free copy of Audacity software is included to start recording right away.
