Precise stereo level control without a mixer!
An affordable high-quality problem solver for mixerless DAW and nonlinear video production environments, the M-Patch provides an ideal desktop stereo level control solution for any monitoring or distributed sound application.
The M-Patch is essentially a multichannel stereo attenuator using passive circuitry designed for users wishing to work without outboard mixers or bit-degrading digital volume attenuators. The M-Patch provides stereo level control solutions for any monitor or distributed sound application. Featuring 2 rotary controls for precise 2X stereo channel level adjustments, and housed in a compact 1/2 RU chassis, the M-Patch is perfectly suited to serve in any common capacity in which more control over volume is desired. From desktop, mixerless DAW and MIDI systems in which no mixer is present to public presentations, professional multichannel installations, distributed sound systems, or audio and video post production environments, the M-Patch adds high quality zone and/or channel control wherever it's needed.
The M-Patch's dual rotary controls allows precise level adjustments within 1dB from 0 to -40dB, with ± .5dB interchannel accuracy to -60 dB. In addition, the M-Patch features completely balanced operation with its combo XLR/TRS input jacks, and XLR outputs, and can be used in unbalanced applications with the RCA & 3.5mm stereo input connectors. 2 stereo output channels are provided (A&B) with a selector switch on the front panel.

There are little if any units available with all the bells and whistles that you get with this unit based on price. Two independent inputs, mute switch, mono or stereo select and multiple speaker selection. Very nice. I works great in my studio set up where I needed additional volume control from my desktop production studio. One issue I had with the unit, the documentation of the cable requirements is not so good. You must use XLR to XLR or RCA to RCA or 1/4" rts to 1/4" rts. The unit will not work with adaptors and or cables that don't have matching terminations ie: XLR to RCA or XLR to 1/4". These type of non matching terminations cause a short circuit in the signal which results in no sound coming through the unit. This isn't documented but needs to be said. Keep this in mind so you don't pull your hair out trying to get it to work.
