PAD - Attenuates the input signal by 30dB. Affects both the XLR and jack inputs. Press this
switch when the input signal is too high even with the GAIN control backed off.
GAIN - Use this control with the PAD switch to adjust the channel input sensitivity to match the
connected source (-60 to +10dBu) to the console operating level (0dBu). Use the PFL function to
check that the signal reads an average ‘0’ on the meters.
100Hz LO-CUT FILTER - Attenuates frequencies below 100Hz to reduce low frequency source
noise such as microphone proximity popping, stage noise and transport rumble. Can be used to
clean up sounds that do not have much bass content such as vocals.
EQUALISER - This provides separate, simultaneous control of 4 frequency bands. Each band
may be boosted or cut by up to +/- 15dB. The centre flat position is detented for quick resetting.
The HF and LF bands have a shelving response which means that all frequencies beyond the
turning point frequency are affected, HF = 12kHz, LF = 60Hz. Use HF to add sparkle or to reduce
source hiss. Use LF to add punch to the bass instruments. Used with the LO-CUT filter you can
tailor the low frequency response exactly as you require.
The two mid frequency bands have a peak/dip (bell shaped) response which means that the
maximum boost or cut occurs at the selected (centre) frequency. The centre frequency can be
swept over a wide range using the SWEEP controls. MF1 = 500Hz to 15kHz, MF2 = 35Hz to 1kHz.
Use the mids to add warmth or presence to the sound or to notch out problem resonances that can
result in feedback.
AUXILLIARY SENDS - You can set up to 6 separately balanced mixes using the aux send
controls. Up to +6dB of boost is available.
Aux 1 and 2 are set pre-fader for monitor sends such as stage monitors, backstage, orchestra pit,
and musicians recording cue. The amount of channel signal in the monitor mix is independent of
the fader level. Pre-fade sends are post-EQ, post-ON as standard (can be reconfigured pre-EQ or
pre-ON by setting internal links).
Aux 3 and 4 are switched pre or post fader for more monitors, effects or separately balanced feeds
for recording and broadcast.
Aux 5 and 6 are set post-fader for sends to external effects devices such as reverb and delay. The
amount of signal sent to the effects device follows the fader level and ON switch. The processed
(“wet”) signal returned to the mix through the aux return inputs is therefore in proportion to the direct
(“dry”) signal from the fader to the mix.
PAN - Positions the channel signal between L and R in the stereo mix. The centre position (mono
image) is detented for quick resetting.
ON - This turns the channel signal on or off.
PEAK - The red LED lights when the signal is within 5dB of clipping. Should this occur turn back
the GAIN control to reduce the signal level.
PFL - Press PFL to listen to the pre-fade signal on headphones or local monitor without affecting
the main outputs. The signal level is shown on the L and R bar meters. The PEAK LED half lights
to show which channel PFL has been selected.
