4

That means that the channel Fader also affects the 

level of a POST aux send. A POST Auxiliary bus is 

what you want to use (almost always) for sending 

to an effects processor, either internal or external.  

When using the POST aux sends, (while turning the 

channel Fader up or down) the level of effects will 

track the channel level correctly.
4 – AUX 1-2 Pre Fader Send

Each of the L series’ input channels include a pair 

of Pre Fader Auxiliary sends; AUX 1-2 and their 

control knobs adjust the amount of that channel’s 

signal that is sent to the AUX 1-2 Output. The signal 

feeding AUX 1-2 is sent before, or pre, the channel 

Fader, so the channel Fader has no effect on the AUX 

1-2 output levels. The AUX 1-2 busses are usually 

used to create a separate mix for a floor monitor 

system. 
5 – AUX 3-4 – Pre/Post Fader 

Each of the L series’ input channels include a pair 

Auxiliary sends which can switch from Pre to Post 

sends; AUX 3-4 and their control knobs adjust the 

amount of that channel’s signal that is sent to the 

AUX 3-4 Output. Aux 3-4 can be configured for pre 

or post fader send using the PRE/POST switch (6).  

The AUX 3-4 bus is usually used to create a separate 

mix for a floor monitor system, but you can set the 

Pre/Post switch to Post to use the send as en effects 

bus to an external processor.
6- PRE/POST - switch  

The PRE/POST switch is used to select the point that 

the AUX 3-4 bus uses to send the signal. When the 

PRE/POST switch is set to PRE, the signal feeding 

AUX 3-4 is sent before the fader, so the channel 

Fader has no effect on that level. This is the normal 

setting when using AUX 3-4 as a monitor send. 

When the PRE/POST switch is set to POST, the 

signal feeding AUX 3-4 is sent after the fader, so the 

channel Fader has an effect on that level, meaning 

the Aux level tracks up and down with the channel 

Fader. This is the normal setting for using AUX 3-4 

as an effects send, since when you set the channel 

loude,r you normally want the effect to get louder.
 Channel Fader up or down the level of effects will 

track the channel level correctly.
7 – EFX1-2 / AUX 5-6 - Post Fader Send

The L series provide high quality, 24 Bit digital 

effects, and the level of effects can be set

independently on each channel. The channel’s EFX1-

2 knob controls the amount of signal that is sent to 

each the two EFX bus feeding the two internal DSP 

effect processors. For additional flexibility, the EFX1-

2 signal can also be sent to an external effect device 

connected to the AUX 5-6 Output jacks located on 

the rear panel jack field.
 8 – AUX 5-6 - switch

The AUX 5-6 switch is used to select the point that 

the EFX1-2 / AUX 5-6 uses to send the signal. When 

a channel’s AUX 5-6 switch is set to on (down), the 

signal from that channel is routed to the AUX 5-6 

bus. This separate mix can be sent to an external 

effect device connected to the AUX 5-6 jacks located 

on the rear panel jack field.
9 - Channel Equalizer - Mono Channels

The L2400 and L3200 mic/line input channels 

incorporate a 3-band, swept-mid equalizer 

allowing you to adjust the high, mid-range, and 

low frequencies independently on each channel. 

The frequency centers, range of boost or cut, and 

equalizer type for each band are described in the 

following section:
HF (HIGH FREQUENCY) 12kHz +/- 15dB Shelving 

The channel’s HIGH frequency response is flat when 

the knob is in the “12:00” position. Rotating the 

knob towards the right will boost the channel's high 

frequency response at 12 kHz by 15dB, and rotating 

it towards the left will cut the high frequency by 

15dB. 
MF (MID FREQUENCY) CUT & BOOST

The MF knob is used in conjunction with the 

FREQ knob to create the tonal shape in the mid-

range frequency when using the mono channel’s 

equalizers. You can adjust the frequency on the 

mid-range control with the FREQ knob, and use the 

MF control to either boost or cut that frequency by 

plus or minus 15dB. The channel’s MID frequency 

response is flat when the MF knob is in the “12:00” 

position.
FREQ (MID FREQUENCY) Variable 100Hz – 8K

The FREQ is a control enabling you enhanced 

capabilities in the tonal shaping of the input channel 

signal. Thanks to the FREQ control, you have a 

variable mid-range equalizer, allowing you to pin 

point the exact frequency you want to boost or cut. 

The MID SWEEP has a “fixed Q” of two octaves (the 

amount, or width, of frequencies
