EQ 

 
All channels have a “full kill” 4 band EQ; the EQ band frequencies are Bass up to 120Hz, Low 
Mid 120Hz to 800Hz, High Mid 800Hz to 4.0KHz and Treble above 4.0Khz. 
 
Variable frequency high and low pass filters 
 
Each channel has variable frequency high pass and low pass filters that are selected by a 
switch. The low pass filter is variable from 20KHz to 2KHz and the high pass filter is variable 
from 20Hz to 2KHz. The filters should be selected before the audio is routed to the output 
(fader down). 
 
These filters operate best with a signal level of around 0dB. Once selected the filters can be 
set to 20Hz and 20KHz where they have a minimal effect and the frequencies adjusted either 
live or on cue. 
 

Channel meter 

 
Each channel has a 12 LED meter to indicate channel level, left and right are summed to 
mono and the level adjusted by -6dB so that the input meter indicates an average of left and 
right indicated in the output (the channel indication will show the same level as left and right 
output meter indication if left and right are equal). 
 
Each channel also has a clip LED to indicate when the input is excessive or clipping. 
 

FX 

 
Each channel has an FX switch that when operated sends that channel to the FX send jack and 
routes the FX return jack to the selected channel via a wet/dry control in the output section. 
 
This allows a single FX unit to be used for both channels without changing connections, the FX 
switch should be operated with fader down, use the wet/dry control to bring the FX in or out. Only 
one channel should have FX selected at any time. 

 
XF 

 
The XF switch assigns the channel to one side of the cross fader, channel 1 is left and channel 2 is 
right. Moving the cross fader away from the assigned side reduces that sides signal and the signal 
of the side moved towards increases. The rate of change between across the cross fader can be 
adjusted with the fader curve control. 
 

CUE 

 
The CUE control sends the signal in the channel selected to the headphones section, the signal 
sent will be either that at the top of the fader or a pre EQ signal depending on whether pre-EQ is 
selected in the headphone section or not.
