Controls
- 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.
- MIDI IN – Connect a MIDI controller to transmit signals to the CV and Trig outputs.
- MIDI THRU – Pass the signals received at the MIDI In jack to other devices.
- CV – Send control voltages received via USB or MIDI to other modules.
- TRIG – Send trigger signals received via USB or MIDI to other modules.
- 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 Dubophonic.
| Mode | LED colors | Operation |
| Mode 1 | Red/red | System 15/35/55 CV range, monophonic |
| Mode 2 | Green/red | System 100/2500 series CV range, monophonic |
| Mode 3 | Red/green | System 15/35/55 CV range, duophonic |
| Mode 4 | Green/green | System 100/2500 series CV range, duophonic |
SYNTHRIBE
Download the SYNTHRIBE application from behringer.com to adjust pitch bend range, select MIDI channel and CV mode, and adjust note range (C0 to C9), and do other calibration.
Power Connection
The unit 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.
- Turn the power supply or rack case power off and disconnect the power cable.
- 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 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.
- 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.
- 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.
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 approximate relation to the mounting holes in your module before attaching the screws.
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 partway 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.
