4. EQUALIZER (EQ)
MONAURAL CHANNELS (CHANNELS 1 TO 8):
This three-band equalizer adjusts the channel’s high, mid, and low frequency bands. Setting the knob to the
position produces a flat (linear) frequency response. Turning the knob to the right boosts the
corresponding frequency band, while turning to the left cuts the band. The following table shows the EQ type,
base frequency, and maximum cut/boost for each of the three bands.

STEREO CHANNELS (CHANNELS 9/10, 11/12, 13/14, 15/16):
This four-band equalizer adjusts the channel’s high, hi-mid, lo-mid, and low frequency bands. Setting the
knob to the
position produces a flat (linear) frequency response. Turning the knob to the right boosts the
corresponding frequency band, while turning to the left cuts the band. The following table shows the EQ type,
base frequency, and maximum cut/boost for each of the four bands.

5. AUX1 / AUX2 CONTROLS
The AUX1 knob controls the signal level that the channel sends to the AUX1 bus; the AUX2 knob controls the
signal level to the AUX2 bus. These knobs 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 AUX1 and AUX2 buses.
NOTES:
These controls allow you to output the signal to the AUX buses regardless
of the setting of the ST switch [9].
6. PRE SWITCH
Selects whether the pre-fader or the post-fader signal is fed to the AUX2 bus. If you set the switch ON
(pressed in), the mixing console sends the pre-fader signal (the signal prior to passage through channel
fader [12]), to the AUX2 bus, so that AUX2 output is not affected by the fader. If you set the switch OFF (out
position) the mixing console sends the post-fader signal to the AUX2 bus.
NOTES:
This switch applies to AUX2 only. The signal to the AUX1 bus always
passes through the channel fader first.
