Samson L2400 User Manual

8

The L Series feature two additional STEREO AUX RETURN 

inputs that can be used to return the outputs of the an 

external effects processor, or to connect the output of 

any stereo line level device. The STEREO AUX RETURN can 

be routed to the MAIN mix, or to a pair of AUX outputs, 

allowing you to send the signal to a monitor mix. 

Each of the L Series STEREO AUX RETURN include an AUX 

1 / AUX 3 control knob, which controls the amount of that 

AUX RETURN’S signal that is sent to the AUX output. Use 

the SHIFT switch (38) to select between AUX 1 and AUX 3. 

The signal feeding AUX 1 / AUX 3 is sent before, or pre, the 

channel Level control, so the channel Level has no effect 

on the AUX 1 and AUX 3 level. 

Each of the L Series STEREO AUX RETURN include an AUX 

2 / AUX 4 control knob, which controls the amount of 

that channel’s signal that is sent to the AUX output. Use 

the SHIFT switch (38) to select between AUX 2 and AUX 4. 

The signal feeding AUX 2/AUX 4 is sent before, or pre, the 

channel Level control, so the channel Level has no effect 

on the AUX 2 and AUX 4 level.

The L Series’ STEREO AUX RETURN MAIN control knob 

is used to adjust the overall level of the STEREO AUX 

RETURN to the MAIN left and right bus.

You can use the SHIFT switch to select which pair of AUX 

buses the STEREO AUX RETURN will feed. When the SHIFT 

switch is in the up position, the STEREO AUX    

RETURN feeds AUX1 / AUX2. When the SHIFT switch is in 

the down position, the STEREO AUX RETURN feeds AUX3 

/ AUX4.

The STEREO AUX RETURN’s PFL, or Pre Fader Listen switch, 

allows you to listen to, or “solo”, the STEREO AUX RETURN 

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

switch is pressed down, the STEREO AUX RETURN 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 channel 

Level control. This allows you to listen to a channel by 

itself: (let's say), to check the reverb decay time, or to cue 

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

speakers.

The L2400 and L3200 have a dedicated line level CD/TAPE 

LEVEL input to connect a CD, Tape or MP3 player. The 

CD/TAPE Level control is used to adjust the volume of the 

signal connected to the CD/TAPE input.
41 - PFL switch

The CD/TAPE input channel’s PFL, or Pre Fader Listen 

switch allows you to listen to, or “solo”, the CD/TAPE input 

in the headphones. When the CD/TAPE input channel’s 

PFL switch is pressed down, that channel’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. Since the signal is sent pre fader, you can 

hear the signal regardless of the position of the channel 

Level control. This allows you to listen to a channel by 

itself: (let's say), to cue up a song on a CD player without 

having to play it through the main PA speakers.
