18 EQUALISER
The Equaliser section has HF and LF shelving controls, each with a range switch to provide two centre
frequencies for each control.
Turn the HF knob to the right to boost high (treble) frequencies by up to 15dB at a choice of 6kHz or
12kHz centre frequencies, adding crispness to percussion from drum machines, synths and electronic
instruments. Turn to the left to cut these frequencies, reducing hiss or excessive brilliance.
Turn the LF knob to the right to boost low (bass) frequencies by up to 15dB at a choice of 60Hz or
120Hz centre frequencies, adding extra punch to synths, guitars and drums. Turn to the left to reduce
hum, boominess or improve a mushy sound.
Set both knobs in the centre-detented position when not required.
19 EQ SWITCH
The EQ switch bypasses the Equalisation section when released. Alternately pressing and releasing
the switch provides an easy way of comparing the equalised and unequalised signals.
20 AUXILIARY SENDS
These controls route a mono sum of the input channel signal to any one or more Auxiliary buses.
These are separate from the main outputs and can therefore provide additional outputs for foldback,
echo units or extra loudspeaker `fills’.
AUX 1 & 2 are normally derived after the EQ section and before the channel fader (PRE FADE, POST
EQ), and are therefore unaffected by the fader position and mute status. This makes them particularly
suitable for foldback or monitor feeds, which need to be controlled separately from the main P.A. mix.
AUX 3 & 4 are normally POST EQ, POST FADE but may be altered globally to be PRE FADE by
pressing the appropriate AUX PRE switch on the Master section.
AUX 5 and 6 are derived after the EQ and channel fader (POST FADE, POST EQ), and therefore
follow any changes in fader level. They are normally used to drive effects processing units which are
fed back into the mixer and which must fade out with the input channel.
All of the Aux Sends are muted when the MUTE switch is pressed.
21 BALANCE
The BALANCE control sets the amount of the channel signal feeding the Left and Right Mix outputs,
allowing you to balance the source in the stereo image. When the control is turned fully left or right you
feed only that side of the signal to the mix.
22 ROUTING SWITCHES
The input channel signal may be routed in stereo to the main Stereo MIX (L-R) or pairs of GROUP
busses (1-2, 3-4 etc.), by pressing the respective switches. The Left side of the channel feeds Groups
1, 3, 5 & 7, and the Right side feeds Groups 2, 4, 6 & 8, subject to the position of the BALANCE control
(21).
23 FADER
This long-throw fader determines the proportion of the channel in the mix and provides a clear visual
indication of channel level. Normal operating position is at the `0’ mark, providing 10dB of gain above
that point if required.
