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 Mi-
crophone 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.
