installation
The M-Patch 4M can sit comfortably on your desktop, with all controls within easy reach.
Alternately, the included rack ears can be used for situating the unit in a standard 19”
rackmount confi guration.
Audio input Connections
The M-Patch 4M features four types of inputs, two of which are balanced and two of
which are unbalanced. The Balanced Inputs feature combination XLR – 1/4” TRS con-
nectors, while the AUX Inputs feature RCA and 1/8” TRS unbalanced connectors. All
inputs are located on the M-Patch 4M’s rear panel.
IMPORTANT! The M-Patch 4M accepts mic or line level input signals only. Do not
connect your power amplifi er outputs to the M-Patch 4M’s inputs—this will dam-
age the internal circuitry, and will NOT be covered under warranty.
Balanced Inputs
The main Balanced Inputs 1 and 2 are ideally suited for connecting to your
audio interface(s) and/or mixer. Simply connect the outputs of your interface
to the inputs of the M-Patch 4M, and use the rotary volume controls under
the Studio 1 and Studio 2 Input Selectors to attenuate the signals as needed.
(Note: Set the attenuators fully clockwise if no attenuation is necessary.)
AUX Inputs
The Aux input channels features two different connector types, ideally
suited for signals from unbalanced devices such as CD players (RCA)
and MP3 players or computer soundcards (1/8” TRS).
*NOTE: You can connect up to six different devices to the physical con-
nectors simultaneously. Use the front panel Studio 1 & 2 and Master Bal-
anced / Aux selector switches to choose the signal(s) you wish to monitor.

Control Room Outputs
The M-Patch 4M has two sets of Control Room
(C/R) outputs, each of which will carry the input sig-
nals chosen by the front-panel Control Room 1 and
2 input selector switches. Use these outputs to route
input signals to your monitor speakers. The levels
appearing at the Control Room 1 & 2 outputs can be
attenuated using the front-panel Master rotary vol-
ume control. The C/R signal path is totally passive.
