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 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.
2
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 (3/4 and
5/6), 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.
3
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 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.
5
EFFECT Controls
Adjusts the level of the signal sent from the channel to
the EFFECT bus. Note that the signal level to the bus is
also affected by the Channel LEVEL Control. If you are
using stereo channels (CHs 3/4, 5/6, 7/8), the signals
from the L (odd) and R (even) channels are mixed and
then sent to the EFFECT bus.
6
PAN Control (CHs 1 and 2)
PAN/BAL Control (CHs 3/4 and 5/6)
BAL Control (CH 7/8)
The PAN control determines the positioning of the chan-
nel’s signal on the Stereo L and R buses.
The BAL control knob sets the balance between left and
right channels. Signals into the L input (odd channel)
feed to the Stereo L bus; signals into the R input (even
channel) feed to the Stereo R bus.
On channels where this knob provides both PAN
and BAL controls: The knob operates as a PAN
control if you are inputting through the MIC jack
or into the L (MONO) input only, and operates as a
BAL control if you are inputting into both L and R
inputs.
7
Channel LEVEL Control
Adjusts the output level of the signal being input to the
channel. Use these LEVEL Controls to adjust the vol-
ume balance among the various channels.
To reduce noise, set the LEVEL Control knobs for
unused channels all the way to the left (to the min-
imum setting).
