Input Module 

LOW 

The control has shelving response that giving 15dB 

of boost or Cut at 80Hz

Adding warmth to vocals or 

extra punch to guitars

drums and synths but turn 

to the right, turn to the left to reduce stage rumble, 
hum or to improve a mushy sound

 

6. AUX l 

This rotary fader sends out the channel signal  to 
auxiliary bus 1

The signal is ere-fader So that the 

aux  send  10  be  independent  of  the  fader:  this  is 
suitable for feedback or monitor

 

AUX 2 

This rotary  fader sends out  the  channel  signal  Io 
auxiliary bus 2

The signal is pre-fader so that the 

aux  send  to  be  independent  of  the  fader,  this  is 
suitable for feedback or monitor

 

7. EFF 

This  rotary  fader  feeds  the  channel  signal  to  the 
external effect the signal is post fader

This is very 

helpful  for  simultaneously  adjust  the  level  of  the 
processed signal

 

8. PAN 

This rotary control determined the assignment of 

signal forth the channel to left and right or 1 and 2 
groups

When the pan pot is set centrally signal is 

sent  equally  to  all  selected  groups  and 
master

Turning  the  control  anticlockwise  send 

relatively more signal to the left master and to the 

SUB1  Turning  the  pot  clockwise  sends  relatively 
more signal to the right master and to SUB2

The 

pan pot may thus be used to adjust the position of 
signals in the stereo image

 

9. PEAK 

This  red  LED  (light  emitting  diode)  illuminates 

when  the  channel  approaches  an  overload 
situation

the  LED  is  activated    3dB  before  the 

onset of clipping (distort)

The input GAIN control 

should be adjusted So that the LED does not flash 
except on the highest level

brief transients

Using 

excessive  amounts  of  boots  on  the  channel 
equalizer may cause distortion on the channel

if 

this happens turn the input    GAIN control down
