1199 EEQQ SSW WIITTCCHH
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.
2200 AAUUXXIILLIIAARRYY SSEENNDDSS
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 & 3 are 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 may be selected internally to be
post-fade.
AUX 4, 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.
AUX 4 may be altered globally to be PRE FADE by pressing the AUX 4 PRE switch
on the Master section.
All of the post-fade Aux Sends are muted when the MUTE switch is pressed.

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.
2222 RROOUUTTIINNGG SSW WIITTCCHHEESS
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), by pressing the respective switches. The Left side of
the channel feeds Groups 1 & 3, and the Right side feeds Groups 2 & 4, subject to the
position of the BALANCE control (21).
2233 FFAADDEERR
This long-throw fader determines the proportion of the channel in the mix and pro-
vides a clear visual indication of channel level. Normal operating position is at the `0’
mark, providing 10dB of gain above that point if required.
2244 M MUUTTIINNGG
All post-fade outputs from the channel may be muted by pressing the MUTE switch,
and the associated LED illuminates to show that the channel is OFF.
Alternatively the channel may be selected to any one or more MUTE BUSES to pro-
vide grouped muting under the control of the MUTE masters on the far right-hand side
of the console. In either case the mute status is shown by the LED.
2255 PPFFLL
When the PFL switch is pressed, a mono sum of the pre-fade signal is fed to the
headphones and L & R meters, where it replaces the normal Mix L/R 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 trac-
ing problems.
