The centre two pairs of knobs are arranged as HI MID and LO MID frequency sec-
tions, with a cut/boost control (lower knob) of +/- 15dB, and a SWEEP(frequency) con-
trol which determines at which frequency the boost/cut action will be centered. These
MID sections, with a combined frequency range from 75Hz to 15kHz are particularly
versatile for vocals, enabling particular characteristics of the singer to be lifted or sup-
pressed very precisely.
Set the cut/boost control of each section to the centre-detented position when not
required.
4 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.
5 AUXILIARY SENDS
These controls route the input channel signal to any one or more Auxiliary busses.
These are separate from the main outputs and can therefore provide additional outputs
for foldback, echo units or extra loudspeaker `fills’.
AUX 1 is normally derived after the EQ section and channel fader (PRE-FADE,
POST-EQ), and is therefore unaffected by the fader position and routing status. This
makes the send particularly suitable for foldback or monitor feeds, which need to be
controlled separately from the main P.A. mix. All pre-fade sends (see also Aux 2 & 3
below) may be selected internally to be PRE-FADE, PRE-EQ.
AUX 2, 3 and 4 are normally 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.
AUX 2 and 3 may be altered globally to be PRE FADE, PRE EQ by pressing the
AUX 2 PRE and AUX 3 PRE switches on the Master section. The pre-fade source on
each channel may be selected internally to be POST-EQ if required.
All of the post-fade Aux Sends are muted when neither MIX or MONO routing
switch is pressed.
6 PAN
The PAN control determines the position of the signal within the stereo mix image.
Rotation fully anticlockwise feeds the signal solely to the Left mix bus, while rotation
clockwise sweeps the image to the Right.
7 ROUTING SWITCHES
The input channel signal may be routed to the main Stereo MIX (subject to the posi-
tion of the PAN control) or MONO by pressing the respective switches. If either or
both switches are pressed, the ON LED illuminates to show that the channel is con-
tributing to the output and that any Auxiliary Send is potentially active.
8 PFL/PEAK
When the PFL switch is pressed, the Pre-Fade signal is fed to the headphones and L
& R meters, where it replaces the normal Mix L/R or Mono signal. The PFL/AFL ON
LED on the Master section illuminates to warn that the headphones and the meters are
now responding to the PFL/AFL selection and the PFL LED on the input channel lights to
identify the active channel. This is a useful way of listening to any required input signal
without interrupting the main mix, for making adjustments or tracing problems.
