level to the output of the mixer.
Note that some sound equipment, particularly that intended for domestic use, operates at a lower level (-
10dBV) than professional equipment and will therefore need a higher gain setting to give the same output
level.
See ‘Initial Setup’ on page 31 to learn how to set the GAIN correctly.
5 100Hz HI-PASS FILTER
Pressing this switch activates a steep 18dB per octave filter which reduces the level of bass frequencies only.
Use this in live PA situations to clean up the mix, reducing stage rumble or ‘popping’ from microphones.
6 EQUALISER
The 3 band swept Equaliser (EQ) allows fine manipulation of the frequency bands, and is particularly useful
for improving the sound in live PA applications where the original signal is often far from ideal and where
slight boosting or cutting of particular voice frequencies can dramatically improve clarity.
HF EQ
Turn clockwise to boost high (treble) frequencies (12kHz and above) by up to 15dB, adding crispness to
cymbals, vocals and electronic instruments. Turn anticlockwise to cut by up to 15dB, reducing hiss or excessive
sibilance which can occur with certain types of microphone. Set the knob in the centre-detented position
when not required.
MID EQ
This pair of knobs work together to form a MID frequency EQ section. The lower knob provides 15dB of boost
and cut, just like the HF EQ knob, but the frequency at which this occurs can be set by the upper knob over a
range of 150Hz to 3.5kHz. This allows some truly creative improvement of the signal in live situations,
because the mid band covers the range of most vocals. Listen carefully as you use these controls together to
find how particular characteristics of, for instance, a vocal signal can be enhanced or reduced. Set the gain
(lower) knob to the centre-detented position when not required. Note: Q is set at 1.5.
LF EQ
Turn clockwise to boost low (bass) frequencies (80Hz and below) by up to 15dB, adding warmth to vocals or
extra punch to synths, guitars and drums. Turn anticlockwise to cut low frequencies by up to 15dB for
reducing hum, stage rumble or to improve a mushy sound. Set the knob to the centre-detented position
when not required.
7 AUX SENDS
These are used to set up separate mixes for FOLDBACK, EFFECTS or recording, and the combination of each
Aux Send is mixed to the respective Aux Output at the rear of the mixer. For Effects it is useful for the signal
to fade up and down with the fader (this is called POST-FADE), but for Foldback or Monitor feeds it is
important for the send to be independent of the fader (this is called PRE-FADE). All Aux Sends are muted with
the other channel outputs when the MUTE switch is pressed.
Aux 1 is always PRE-FADE, POST EQ, and would typically be used as a foldback or monitor feed. Aux 2 & 3 are
normally POST-FADE, POST-EQ for use as effects sends or additional submixes, but for flexibility Aux 2 may be
switched to PRE-FADE, POST-EQ by pressing the associated PRE switch.
8 FX
The FX control is identical to the post-fade Aux 3, but the signal is sent to the internal bus which feeds the
input of the built-in LEXICON® digital effects processor. The output of the LEXICON processor may be added
to the Mix or Subs and/or Aux 1 or 2 busses.
