1. USB – Connect to a computer to transmit MIDI control signals to the
CV and Trig outputs. The module can also receive firmware updates via
this connection.
2. MIDI IN – Connect a MIDI controller to transmit signals to the CV and
Trig outputs.
3. MIDI THRU – Pass the signals received at the MIDI In jack to other devices.
4. CV – Send control voltages received via USB or MIDI to other modules.
5. TRIG – Send trigger signals received via USB or MIDI to other modules.
6. TRIG MODE – Selects whether the Trig outputs function as V-trig or S-Trig.
In the middle position, the upper output functions as S-trig and the lower
output functions as V-trig.
Mode Select
A button on the rear panel allows the CM1A to be configured for use with various
synth families offered by Behringer. The first LED indicates whether the CV range
is optimal for System 15/35/55 or System 100/2500 series modules.
The second LED indicates monophonic or duophonic operation.
Press the button quickly to switch the CV range, or press and hold to switch
between monophonic and duophonic.

Power Connection
The CM1A module comes with the required power cable for connecting to a
standard Eurorack power supply system. Follow these steps to connect power to
the module. It is easier to make these connections before the module has been
mounted into a rack case.
1. Turn the power supply or rack case power off and disconnect the power cable.
2. Insert the 16-pin connector on the power cable into the socket on the power
supply or rack case. The connector has a tab that will align with the gap in the
Installation
The necessary screws are included with the module for mounting in a Eurorack
case. Connect the power cable before mounting.
Depending on the rack case, there may be a series of fixed holes spaced 2 HP
apart along the length of the case, or a track that allows individual threaded
plates to slide along the length of the case. The free-moving threaded plates
allow precise positioning of the module, but each plate should be positioned in
the approximate relation to the mounting holes in your module before attaching
the screws.
Quick Start Guide
socket, so it cannot be inserted incorrectly. If the power supply does not have
a keyed socket, be sure to orient pin 1 (-12 V) with the red stripe on the cable.
3. Insert the 10-pin connector into the socket on the back of the module.
The connector has a tab that will align with the socket for correct orientation.
4. After both ends of the power cable have been securely attached, you may
mount the module in a case and turn on the power supply.
Hold the module against the Eurorack rails so that each of the mounting holes
are aligned with a threaded rail or threaded plate. Attach the screws part way
to start, which will allow small adjustments to the positioning while you get
them all aligned. After the final position has been established, tighten the
screws down.
