PHONO / LINE INPUT CHANNELS 1 and 4 

Channel Fader

 

 
A high quality, smooth travel dual-rail fader adjusts the 
channel signal level from fully off to fully on. 

XFade Switch

 

 
Used to assign the channel to either the X (left) or Y 
(right) side of the cross-fader.  Works in conjunction 
with the XFADER On switch in the master section. 
 
A bi-colour LED indicator illuminates either green (X) 

or red (Y) to show which side of the cross-fader has 
been selected. 

Channel Meter 

 
Displays the channel signal level.  It is pre-EQ and pre-
fader, allowing the input level to be displayed even if the 
EQ is set to off on all bands.  To view the post EQ level, 
press the cue switch and use the mix/monitor meters.    
 

The channel level control should be set so that the me-
ter averages around ‘0’ with loudest peaks no higher 
than ‘+6’.  Turn down the level control if the +10 peak 
indicator lights. 

Cue Switch

 

 
Press the Cue switch to listen to the channel pre-fade 
signal in the headphones and see its level on the main 
meters.  The LED indicator next to the switch lights 
when selected.  The Cue LED indicator in the monitor 
section also lights to warn that you are monitoring the 

channel signal rather than the main mix.  Press the 
switch to deselect cue.
