The RM219 Channel One is designed to receive a microphone level signal, all other chan-
nels 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 amplifi er,
snake, or mixer.
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 RM219.
NOTE: The RM219 Aux Send jack may also be connected to an amplifi er, then to speak-
ers and used as a Monitor Send.
