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 con-
trolled 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 pro-
cessing 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 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.
24 MUTING
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 provide
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.
25 PFL
When the PFL switch is pressed, a mono sum of the pre-fade signal is fed to the head-
phones 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 tracing problems.
