Tascam US428 USB Digital Audio Workstation Controller (Windows or Macintosh)

Tascam and Frontier Design Group have partnered together to create the first major innovation in USB-based audio. Start with a fully 24-bit front end, with 2 XLR inputs, 2 balanced 1/4 in. TRS inputs, 2 unbalanced 1/4 in. inputs (switchable to Hi-Z), and S/PDIF I/O. Four channels of audio in and 2 out simultaneously via USB. No opening your computer, no sound card to install - it's USB, so you can even hot-plug it.

You'll spend a lot less time mousing your mix with the US-428. It's got real tactile controls for the most-used functions in your DAW applications. Transport, mute/solo, and locate keys, unlimited banks of 8 faders, an EQ module that supports control of up to 4 bands of fully parametric EQ, plus 4 aux sends and a panpot. It's even got 32 channels of MIDI I/O. Use one for your keys and modules and the other for MTC to lock your MTC-capable tape tracks to your computer.

The US-428 comes bundled with Steinberg's Cubasis VST audio recording/MIDI sequencing software.
