Samson SAMDR1248 Manuale Utente

16

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.
