vice of high class that meets the demands of the home/pro studio.

production environments, the M-Patch 2 provides an ideal desktop stereo level con-
trol solution for any monitoring or distributed sound application.

precise two x stereo channel level adjustments, and housed in a compact desktop
or rack-mountable sized chassis, the M-Patch 2 passive volume control and patch
control device is perfectly suited to serve in any common capacity in which more
control over volume is desired. From desktop media suites, mixer-less DAW and
MIDI systems, professional multi-channel installations, distributed sound systems,
or any other audio and video post production environments, the M-Patch 2 adds high
quality zone and/or channel control wherever it‘s needed.
