Description

The M-Track Duo is a compact two-channel USB audio interface working at 48 kHz. Each of its two combo inputs accepts a microphone, an instrument or a line-level source, and a dedicated switch selects between line and instrument level. The Crystal preamps supply +48V phantom power for condenser microphones. The unit takes its power from the USB connection, so it runs from a laptop without a separate supply.

Monitoring is handled in hardware. A USB/Direct Mono/Direct Stereo switch sets the balance between the direct input signal and computer playback, giving latency-free monitoring of mic, line or instrument sources. The signal is available on the stereo 1/4" main outputs and on a 1/4" headphone output with its own level control.

The interface connects to Mac, PC and iOS devices over USB. A software bundle is included: the MPC Beats DAW, AIR Electric, Bassline and TubeSynth instruments, 80 AIR effect plug-ins and the ReValver guitar amp modelling plug-in.
