out low frequency hum.
5 EQUALISER
The Equaliser(EQ) comprises four sections. The upper control provides H.F.(treble) boost and cut of
+/-15dB at 13kHz, and the lower control provides L.F. (bass) boost and cut of +/-15dB at 60 Hz.
The centre two pairs of knobs are arranged as HI and LO MID frequency sections, with a cut/boost
control (lower knob) of +/- 15dB, and a SWEEP(frequency) control which determines at which
frequency the boost/cut action will be centered. These MID sections, with a combined frequency
range from 80Hz to 13kHz are particularly versatile for vocals, enabling particular characteristics of the
singer to be lifted or suppressed very precisely.
Set the cut/boost control of each section to the centre-detented position when not required.
6 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.
7 AUXILIARY SENDS
These controls route 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 selected globally to be PRE FADE, POST
EQ by pressing the appropriate AUX PRE switch on the Master section. The AUX PRE source may
also be selected as PRE EQ by internal jumpers as decribed in Appendix 2 later in this manual.
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 post-fade Aux Sends are muted when the MUTE switch is pressed.
8 PAN
The PAN control determines the position of the signal within the stereo mix image or may be used to
route the channel signal to particular output GROUPS# as selected by the ROUTING SWITCHES
(see below). Rotation fully anticlockwise feeds the signal solely to the Left mix buss or Groups 1, 3, 5
and 7, while rotation clockwise sweeps the image to the Right buss or Groups 2, 4, 6 and 8.
9 ROUTING SWITCHES
The input channel signal may be routed to the main Stereo MIX (L-R) or pairs of GROUP busses (1-
2, 3-4 etc.), by pressing the respective switches. These may be used in conjunction with the PAN
control (8 above) to route the channel signal proportionately to any of the selected busses.
10 FADER
This 100mm 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.
