The M-Patch 2 is a compact desktop/rack-mountable sized passive volume attenuator and patch control device. Building on the success of the original M-Patch, the new M-Patch 2 is a feature packed passive problem solver for nearly all production environments. The M-Patch 2 provides an ideal desktop or rack mounted, stereo level control solution for any audio monitoring application.A great way to passively attenuate stereo signals from soundcards, CD players, pre-amps, and mixers, the M-Patch 2 front panel rotary controls allow precise level adjustments for two input sources. Featuring balanced combo XLR/TRS input jacks and XLR outputs, RCA & 3.5mm jack inputs, mono/stereo summing switch, Mute switch, A/B output pairs, and a built in stereo headphone amplifier, the M-Patch 2 has all bases covered.

It simply delivers attenuated signal. That's it... pure, simple transparent.For users wishing to monitor the audio via the built in headphone amplifier, the included external power supply is required. Even with power connected to the unit the main outputs remain outside of the power circuit!The M-Patch 2'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 2 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. Two stereo output channels are provided (A&B) with a selector swit
