Offers better performance in a smaller package.

The Tascam US-144MKII seamlessly continues the worldwide success of its predecessor US-144 offering better recording quality from a USB MIDI interface further reduced in size. Since it doesn't require an additional power supply, this portable audio interface is perfect for creating 4-channel recordings from analog and digital sources with a laptop computer.

Two XLR microphone inputs with switchable phantom power and high-quality preamps are the basis for good-sounding recordings, while input signals can be listened to by headphones with zero latency. Line-level and digital sources or an instrument can be connected as well. The Tascam USB MIDI interface has separate level controls for the line and headphones outputs, a mono switch, MIDI input and MIDI output, as well as a coaxial SPDIF output.

The US-144MKII interface supports sample rates up to 96 kHz at 24-bit resolution. While commercial audio CDs are produced at 44.1 kHz/16-bit, this interface offers you more than double the sample rate which means more detail for your recordings. (If you're fine with two audio channels and don't need a digital I/O, have a look at the Tascam US-122MKII.)
