FRONT PANEL CONTROLS – CHANNEL CONTROL SECTION 
 
(1). PEAK LED INDICATOR   
This LED indicators lets you check the level of the signal input to the channel. 
The peak indicator lights when the input signal reaches 5dB below the 
channel’s clipping point. This indicator shows the level of the Post-EQ / 
pre-fader signal. If the PEAK indicator lights more than briefly on high-level 
transients, you should use the GAIN control to decrease the input sensitivity 
of the channel. If this does not work, reduce the output level of the connected 
source.   
(2). GAIN CONTROL   
According to the level of the input signal, use this knob to adjust the input to 
an appropriate level. The best balance of S/N and dynamic range will be 
achieved if you adjust the GAIN control so that the peak indicator lights 
occasionally. This control adjusts the channel’s mic input sensitivity between 
-50dB and -6dB and the line input sensitivity between -30dB and +14dB. The 
mono/stereo combination input channels have a sensitivity of +20dB to 
-20dB.  
 
(3). HPF (High-Pass Filter, cut frequencies below 75Hz)  
 
This switch toggles the HPF on or off. To turn the HPF on, press the switch in 
( ). 
(4). 3 BAND EQUALIZER CONTROLS   
This is a 3-band equalizer with center frequencies, range and type as shown 
below. The frequency response is flat when all knobs are in the “0” position.

(5). AUX CONTROLS   
This knobs control the level of the signals sent to AUX bus.   
(6).PRE/POST SWITCH 
This button determines whether the AUX signal is Pre or Post fader. Pre 
means not affected by the position of the channel fader. Post means is 
affected by the position of the channel fader.   
(7). EFX CONTROLS   
This knobs control the level of the signals sent to EFX bus. The channel signals mixed by this bus have their overall level 
set by the EFX SEND Control to the EFX SEND jack on the front panel. The EFX bus signal is also fed into the internal 
digital signal processor. Since this control is placed after the channel fader, the signal level will be affected by the 
channel fader setting.
