This jack parallels the Channel 1 Microphone Input on the rear panel. NOTE: The following two descriptions are for Mic 1 and Mic 2. LEVEL: Adjusts the amount of signal from the Microphone Input channel to the Main Outputs. TONE: Adjusts the relative frequency components of the Mic signal. Turning this control clockwise from the center (detented) position decreases the high frequencies. Turning the control counter-clockwise from center decreases the low frequencies. SOURCE LEVEL CONTROLS 1 - 4: Adjust the amount of signal from the indicated Source channel to the Main Outputs. BASS: Varies the amount of the low frequency portion (150 Hz) of the Source signals. TREBLE: Varies the amount of the high frequency portion (10 kHz) of the Source signals. HEADPHONE OUTPUT: 1/4î Tip-Ring-Sleeve jack for connection to any standard pair of audio headphones.

PHANTOM POWER: Header pins for applying 12VDC phantom power to the indicated microphone. MICROPHONE INPUTS 1 and 2: Balanced XLR jacks for connecting to dynamic or condenser microphones. 5 2 CONNECTION Ensure the RM75 is securely mounted in a 19î rack. Connect the PS12 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. Shown below is a possible connection example for the RM75. OPERATION Make sure all audio connections are in place, and power is applied to all pieces of equipment necessary for operation, ie; speakers, power amplifiers, 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 (off). Keep the Headphone Level control low and, using the Cue Select switch, select which Source signal you wish to hear. There will be nothing heard from the Main Outputs until you increase the level of a Source or Mic channel. You may now ìcueî or prepare the Source selection for playing. Set the Headphone Level for a comfortable amount. Increase the Source Level of the ìcuedî channel, and begin playing the selection. You may now select a different channel by moving the Cue Select switch to another Source Channel, and ìcueî another song.
