4.4 On/Off Mute switch
The on/off mute switch on the front panel is for
enabling and disabling the M-Patch 2’s built in
mute function. All audio signal output is
disabled when the mute switch is in a depressed
position.
The mute led will illuminate when the system is
in a current muted state of operation.
4.5 Mono/Stereo summing switch
The mono/stereo summing switch on the front
panel of the M-Patch 2 allows you to sum a
stereo signal to a mono signal. This can be very
handy when testing your audio for certain issues
like phase cancellation, preparation for AM radio,
etc.
Select the desired mode of operation by positioning the
mono/stereo switch in the up or down position.

provided for monitoring the
audio signal selected by the

Simply connect a pair of
headphones to the
¼
” TRS
headphone connector socket and use the rotary headphone
volume control knob to adjust the volume level to your
desired setting.
* Note: Use of the headphone amplifier requires the
connection of the external power supply.
