USING THE DIGITAL EFFECTS
The MDR1248 and MDR1688 mixers feature a built-in,
high quality, 24-bit Multi Effect Processor, offering studio
grade digital effects. The MDR’s Effect section features
clean Delay, lush Reverbs and multi-effects like Chorus
+ Delay, Chorus Flange or Chorus + Reverb. You can add
a broad range of studio quality effects by simply dialing
through the 256 presets.
The following details the operation of the internal DSP
effects in the MRD1248 and MDR1688 Effects section:
1. Connect a mic or instrument to the desired channel,
adjust the level and equalizer to your liking and make
sure the MAIN fader level is set so you can hear it in
your speakers.
2. Now select the desired effects program using the
PROGRAM control knob located in the Effects sec-
tion in the middle of the mixer’s Master section.
Set the PROGRAM control knob to one of the 16
effects. You can check the effects Program List below
the PROGRAM knob to find the effect type per-
fect for your performance. The first PROGRAM and
VARIATION banks have been preset with common
effects for live performance, and the following banks
are set up in groups by the types of effects.
3. Once you have selected the desired effects preset,
raise the AUX 2 DSP control on the channels you wish
to apply the digital effect to.

4. Next, locate the AUX SEND 2 knob and turn it about to
a little past “5” or half way.
5. Now, use the AUX RETURN 2 control knob to adjust
the effects return level. The AUX RETURN 2 control
knob sets the overall level control for the DSP effects
processor in the main Left and Right Mix.
6. Now, you can check out different versions of the
PROGRAM presets by using the VARIATIONS control
knob. Each of the 16 effects PROGRAM banks has six-
teen variations providing a total of 256 effects presets.
7. If you want to hear the effects in the monitors, press
the AUX RETURN 2 TO AUX1 switch and you will have
the output of the internal effects routed to the AUX1
output. For more information on setting up a monitor
mix, see the following section.
NOTE: If the DSP PEAK LED lights up and effect sound is
distorted, even though the AUX RETURN 2 is turned down
low, lower the AUX SEND 2 control knob and the AUX2/
DSP controls of each channel.
8. If you want to bypass the effects, you can turn off the
effects processors output by using the DSP MUTE
switch, or an optional footswitch connected to the
FOOTSWITCH jack.
