stereo instrument, or if nothing is plugged into the Left input, the signal connected to the
Right input feeds both sides.
Channel One
Input: Balanced XLR jack for connection to a condenser or dynamic microphone.
Phantom Power: Jumper connector for applying +12V phantom power to the Mic 1 XLR
jack.
Mic Trim: Adjusts the initial gain of the Mic preamp circuitry.
PHANTOM POWER

nects the left two pins as you face the rear of the unit. Shown is an example of
the Phantom Power connected.
CONNECTION / OPERATION
INPUT CONNECTION EXAMPLE
The RM203x Channel One is designed to receive a microphone level signal, all other
channels are designed to receive line-level signals. Connect a microphone to Channel
One, and connect the outputs of each instrument or module via a 1/4” cable to channels
two through ten as shown in Example 1 (See back page). Connect the outputs to an am-
plifier, snake, or mixer.
AUXILIARY SEND/STEREO RETURN CONNECTION EXAMPLE
AUXILIARY SEND/STEREO RETURN CONNECTION EXAMPLE
Connect 1/4” unbalanced cables to the Aux Send to the Input of the signal processor, and
connect each signal processor output to its corresponding Aux Return jack as shown in
Example 2 (See back page). Set the “Mix” control on your signal processor to 100% effect
since the dry portion of the signal is mixed in the RM203.
NOTE: The RM203x Aux Send jack may also be connected to an amplifier, then to speak-
