1 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 indica-
tor (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 lev-
els, and lights red if either of these levels reaches 3 dB
below the clipping level.

Switch (High Pass Filter)
This switch toggles the HPF on or off. To turn the HPF
on, press the switch in (
below 80 Hz. (But note that regardless of the switch set-
ting, 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.

AUX Control
The AUX knob controls the signal level that the channel
sends to the AUX bus. The knob should generally be set
close to the position.
If you are using stereo channels, the signals from the L
(odd) and R (even) channels are mixed and sent to the
AUX bus.
