The SM Pro M-Patch 2.1 Passive Volume Control/Switcher. The mighty M-Patch 2 takes a giant leap forward with the new 2.1 model specially designed for monitoring with a subwoofer. Featuring a new chassis suitable for desktop or rack-mount use, the M-Patch 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 M-Patch 2.1 features the ability to return the signal from the subwoofer back into the M-Patch 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.
