Samson L2400 User Manual

7

The TO AUX 4 control is used to adjust the level of the 

effects from the built-in digital Multi-effect that’s being 

sent to the AUX 4 monitor bus.  This allows you to add the 

DSP effects to the signal in your monitor speakers. Turn 

this knob up if you want to hear the effect in the AUX 4 

monitor mix. 

The EFX ON switch is used to turn the internal Digital 

Effect on and off. The effects are by-passed when the 

switch is in the out position and the Effects Display shows 
two dashes.

The L2400 and L3200’s DSP section also includes a 

PEAK LED which when illuminated, indicates that 

the signal is peaking or overloading.  To reduce 

distortion, lower the EFX controls to keep this LED 

from staying on. 

The EFX RTN 1’s  PFL, or Pre Fader Listen switch allows you 

to listen, or “solo” the EFX 1 Return or group of channels 

in the headphones. When a stereo input channel’s PFL 

switch is pressed down, the EFX RTN 1 signal is assigned 

to the solo bus and can be heard in headphones plugged 

in to the PHONES connector located in the front panel 

jack field. Since the signal is sent pre fader, you can hear 

the signal regardless of the position of the EXF RTN 1 

volume Fader. This allows you to listen a EFX RTN 1 by 

itself: (let's say) to see if a reverb is long enough, or to cue 

up an echo without having to play it through the main PA.

The 1-2 Group assign switch is used to assign the 

DSP RTN1 to the 1-2 Group output bus. 
29 – 3-4 RTN 1 Group Assign switch

The  3-4 assign switch is used to assign the DSP RTN 

1 to the 3-4 Group output bus. 
30 –MAIN  Assign switch

The MAIN assign switch is used to assign the DSP 

RTN 1to the left and right stereo bus outputs. 
31-  RTN1 - Fader Level Control

The RTN1 Fader control adjusts the level of the DSP 1 

effects in the MAIN left and right mix.

Each of the L Series AUX 1-8 buses has a master con-

trol knob, which is used to adjust the overall level 

of that AUX bus output. The Aux 1-8 signals from 

mono and stereo input channels, along with the DSP 

returns are mixed together and sent to the AUX 1-8 

Output respectively. Use the AUX 1-8 level controls 

to set the amount of signal being sent to Aux 1-8 

Output.
34 - AUX 1 - 8 AFL switch

The AUX 1-8 master send output’s AFL, or After Fader 

Listen switch allows you to listen, or “solo” an AUX 

send in the headphones. When any the AUX 1-8 AFL 

switch is pressed down, that Aux’s signal is assigned 

to the solo bus and can be heard in headphones 

plugged in to the PHONES connector located in the 

front panel jack field. This allows you to listen to an 

AUX send by itself, let’s say, to check that a signal is 

not distorted before it gets to the power amplifier. 

Since the signal is sent after the Aux 1 level fader, 

you hear the signal with the added gain from the 

AUX 1 Level control. 

Same as functions 18 – 31 for DSP Multi-effects number 2.
