SM Pro Audio MPatch 2.1 Passive Volume Control
with Subwoofer Output


The mighty MPatch 2 takes a giant leap forward with the SM Pro Audio MPatch 2.1 Passive Volume Control, specially designed for monitoring with a subwoofer.  Featuring a new chassis suitable for desktop or rackmount use, the MPatch 2.1 performs a variety of volume control, level-matching, mixing, and monitoring functions—all without adding any coloration or noise, thanks to its 100% passive circuitry.

The SM Pro Audio MPatch 2.1 Passive Volume Control features the ability to return the signal from the subwoofer back into the MPatch 2.1 and control it, along with the left/right monitors, from the master volume attenuator. Plus dedicated mute switches make it easy to A/B mixes with and without the subwoofer.
