GAIN Control
Adjusts the input signal level.
To get the best balance between the S/N ratio and the 
dynamic range, adjust the level so that the PEAK 
indicator (
2) comes on only at about maximum input 
level.
The –60 to –16 scale indicates the MIC input adjustment 
level. The –34 to +10 scale indicates the LINE input 
adjustment level.

PEAK Indicator
Detects the peak level of the post-EQ signal, and lights 
up red when the level reaches 3 dB below the clipping 
level. For XLR-equipped stereo input channels (5/6 and 
7/8), detects both post-EQ and post-mic-amp peak 
levels, and lights red if either of these levels reaches 3 
dB below the clipping level.
n When the level of an input signal exceeds the level that 
can be handled by the mixer’s head amp or equalizer, 
distortion and noise will result. The PEAK indicators are 
used to visually check the signal level to ensure no 
overload occurs.

 Switch (High Pass Filter)
This switch toggles the HPF on or off. To turn the HPF on, 
press the switch in (
). The HPF cuts frequencies 
below 80 Hz. (But note that regardless of the switch 
setting, the mixer does not apply this HPF to the line 
inputs of stereo input channels.) 
4
Equalizer (HIGH, MID, and LOW)
This three-band equalizer adjusts the channel’s high, 
mid, and low frequency bands. Setting the knob to the   
position produces a flat frequency response. Turning the 
knob to the right boosts the corresponding frequency 
band, while turning to the left attenuates the band. The 
following table shows the EQ type, base frequency, and 
maximum cut/boost for each of the three bands.
n The equalizer can be used to boost or cut specific 
frequency bands, allowing the tone of the sound to be 
shaped as required by the mix.
