6 - INSERT POINT
The unbalanced, pre-EQ insert point is a break in the channel signal path, allowing limiters,
compressors, special EQ or other signal processing units to be added in the signal path.
The Insert is a 3-pole 'A' gauge jack socket which is normally bypassed. When a jack is
inserted, the signal path is broken, just before the EQ section. The Send may be tapped off
as an alternative pre-fade, pre-EQ direct output if required, using a lead with tip and ring
shorted together so that the signal path is not interrupted.
7 - EQUALISER
The Equaliser (EQ) allows fine manipulation of the frequency bands, and is particularly use-
ful 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 really make a
difference to clarity.
HF EQ
Turn clockwise to boost high (treble) frequencies (12 kHz and above) by up to 15dB, add-
ing 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 micro-
phone. Set the knob in the centre-detented position when not required.
MID EQ (HMID & LMID)
There are two pairs of knobs which work together to form HI and LO MID frequency EQ sec-
tions. The lower knob in each pair 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 550Hz
to 13 kHz (HMID) or 80Hz to 1.9k Hz (LMID). This allows some truly creative improvement
of the signal in live situations, because the mid bands cover 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 (60Hz 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.
8 - 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.
9 - AUX SENDS
These are used to set up separate mixes for FOLDBACK, EFFECTS or recording, and the
