The MOTU Track16 Track16 Desktop Studio FireWire/USB 2.0 Interface is a versatile and compact unit that offers a wide range of inputs and outputs, as well as effects, mixing, and monitoring. It's equipped with eight channels of analog ins and outs including mic, line, and high-impedance instrument inputs. The analog connectors come on a 44-inch breakout cable, which gives you flexibility for setup and connections (an optional breakout box is also available). For digital I/O, the unit's optical ports support either eight channels of ADAT, four channels of SMUX optical, or two channels of optical S/PDIF on TOSlink connectors. MIDI in and Out jacks are also included. Housed in an aluminum-alloy chassis, Track16 supports professional-quality 24-bit recording at sampling rates up to 192 kHz, and has a user interface that was designed to be simple and intuitive. The large knob in the center of the unit can be set to control levels for any of the inputs or outputs with just a single tap on one of the front panel buttons. User-assignable LED meters make it possible to see levels from any of the units inputs or outputs.
