DESCRIPTION
FRONT PANEL
- INPUT: Balanced XLR jack for connection to a dynamic or condenser microphone. This jack paral-lels 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 clock-wise from the center (detented) position decreases the low frequencies. Turning the control counter-clockwise from center decreases the high frequencies.
- SOURCE LEVEL CONTROLS 1 – 4: Adjust the amount of signal from the indicated Source channel to the Main Outputs.
- IN 4: 1/8” (3.5 mm) Source Input jack. This jack parallels the Source 4 Input on the rear panel.
- 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 LEVEL: Adjusts the amount of signal to the Headphone Output.
- HEADPHONE OUTPUT: 1/8” Tip-Ring-Sleeve jack for connection to any standard pair of audio headphones.
- pwr LED: Indicates that the RM69 is powered on.
REAR PANEL
- 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 eff ects processor. Allows for eff 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 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 amplifi 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 (off ). Keep the Headphone Level control low at fi 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.
USING THE MIC EFFECTS INSERT
- In order to add eff 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 eff ects processor’s Input
- jack, and the Ring connection to the Output of the eff ects processor. The RM69 eff ects insert is mono, so if the eff ects processor is stereo – choose a Mono output. You may need to refer to your eff 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 eff ects processor for the desired process and level of eff ect.
