Tascam - US-122L USB/中型控制表面

AUDIO USB / MIDI 接口

Record two tracks at a time and monitor them with zero latency. Whether you have a PC or a Mac, your song ideas go down in real time, real easy. Its size means you can take it anywhere you take your laptop, yet it's packed with features that make buying it an audio no-brainer. MIDI input and output, high quality mic inputs, 96kHz/24-bit recording (better than CD quality)-all the stuff you'd want without the fluff you wouldn't (if you need a digital SPDIF I/O, have a look at the US-144). The US-122L: the answer to your recording needs.
