INSTALLATION AND CONNECTION

Follow the procedure below to have a signal processed for each channel:

1. Turn down all Input and output gain controls.

2. Connect phantom powered microphones before switching on the +48 Volt phantom power switch.

3. Set the output level of your RMX508DFX at no more than 75%.

4. Set the MAIN level at no more than 50%. In this way you will be able to hear the signal by connecting a

5. Position EQ controls on the middle position.

6. Position panoramic (PAN) control on center position.

7. Increase the input gain properly for maintaining the good headroom and ideal dynamic range.

8. Depending on the actual application, slowly turn the input and output level controls to obtain the

9. Repeat the same sequence for all input channels. The main LED meter may move up into the red LED

Notes:

y Microphones, monitors, amplifier, speakers, cables, etc. are not included. y To reduce electrical hum at high gain settings, keep the mixer's power supply away from your guitar cable and

y To use an external effects rack unit, co mpressor, et c., us e a Y-cable (1/4" stereo to two 1/4" mono) to connect

CONTROL ELEMENTS

1. MIC/LINE MONO INPUTS – Connect a microphone or line level instrument to these inputs using standard XLR or ¼” cable.

2. MIC/LINE STEREO INPUTS- These XLR and ¼” TRS connections are

organized in stereo pairs. If you connect only the left jack, the input will operate in mono mode, (the mono signal will appear on both input channels). You can use these inputs with a stereo keyboard, drum machine, etc.

3. LEVEL – Adjusts the channel audio level (pre-fader and pre-EQ gain). Adjust this so that the PEAK LED rarely lights up during the loudest parts of the song.

4. CHANNEL BAL – Adjusts the channel's position in the stereo field.

5. AUX 1 Pre – This adjusts the prefader signal sent to the Monitor output and

is controlable using the Monitor Level knob.To use an external effects rack unit, compressor, etc. with the mixer, you can use a Y-cable to connect the AUX out to the input of your external device, then connect the outputs of the device to the Stereo Return of the amp.

6. AUX 2/FX Post- This adjusts the post fader signal which is sent through the AUX OUT and is controllable with the DSP knobs to route the signal to the MON or MAIN outputs. You can use a 1/4" TRS cable to connect the AUX OUT to the input of an external amplifier or active monitor to create a custom mix for onstage musicians with the mixer’s internal effects.

7-9. EQUALIZATION- You have three EQ controls for each mono and stereo

input channel each providing +/-15 dB of boost and cut. The signal will be unaffected when the controls on the center position. You may use an external equalizer to make up a mix properly but a master equalizer will not have effect on a single channel and you may overload the signal easily. Individual EQ will give you a much better control on single tracks.

7. HI EQ (TREBLE) – Adjusts the high (treble) frequencies of the channel.

8. MID EQ – Adjusts the mid-range frequencies of the channel.

9. LOW EQ (BASS) – Adjusts the low (bass) frequencies of the channel.

10. -20dB PAD- Pressing this button will attenuate the input signal by 20 dB.

This will give increased headroom and reduce the risk of distortion from

input signal peaks.
