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-
