SCHEMATIC
USING THE MIC EFFECTS INSERT
In order to add e ects to the microphone signal, an insert cable is needed. The Tip of the plug
acts as the Send, the Ring is the Return.
Connect the insert cable’s TRS end to the Mic FX
Insert jack on the rear of the RM69. Connect the
Tip connection to your e ects processor’s Input
jack, and the Ring connection to the Output of
the e ects processor. The RM69 e ects insert
is mono, so if the e ects processor is stereo choose a Mono output. You may need to refer
to your e ects processor owners manual for more information about operating it in mono.
Make sure a microphone is properly connected to the RM69 and the unit is on. Speak into the
microphone and adjust the levels of your e ects processor for the desired process and level of
e ect.

MAIN OUTPUTS
DC INPUT: Connects to the included Rolls PS27s power adapter.
LINE OUTPUTS RCA: Unbalanced output jacks
XLR: balanced ouput jacks
SOURCE INPUTS: Unbalanced RCA input jacks.
FX INSERT: 1/4” Tip-Ring-Sleeve jack for connection to an insert plug (see diagram) and to an
e ects processor. Allows for e ects to be added to the microphone signals.
PHANTOM POWER: Dip switches for applying phantom power to the indicated microphone.
MICROPHONE INPUTS 1 and 2: Balanced XLR jacks for connecting to dynamic or condenser
microphones.
CONNECTION
Ensure the RM69 is securely mounted in a 19” rack. Connect the power supply to an AC outlet
(preferrably a power strip with master switch). If the unit is to be used in a permanent install,
connect all sources and microphones to the desired channels on the rear panel. Remember
which signal sources are connected to which Source Inputs.
For use in mobile DJ/Karaoke rigs, the microphone should be connected to the front panel Microphone Input so it may be easily removed when the mobile rig is packed.
OPERATION
Make sure all audio connections are in place, and power is applied to all pieces of equipment
necessary for operation, ie; speakers, power ampli ers, microphones etc.
Normally, only one source signal is heard at a time along with a microphone signal. Therefore,
begin with all Levels completely counter-clockwise (o ). Keep the Headphone Level control
low at rst. There will be nothing heard from the Main Outputs until you increase the level of a
Source or Mic channel. You may now turn up the Source’s for playing. Set the Headphone Level
for a comfortable amount. Increase the Source Level of the desired channel, and begin playing
the selection.
