background hiss will be more noticeable and you may not be able to get enough signal

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 22 to learn how to set GAIN correctly.

5 Equaliser

The Equaliser (EQ) allows fine manipulation of the sound, particularly to improve 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. There are three sections giving the sort of control usually only found on much

larger mixers. The EQ knobs can have a dramatic effect, so use them sparingly and

listen carefully as you change any settings so that you get to know how they affect the

sound.

HF EQ

Turn to the right to boost high (treble) frequencies above 12kHz by up to 15dB, adding

crispness to cymbals, vocals and electronic instruments. Turn to the left 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

There are two knobs which work together to form a SWEPT MID EQ. 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 140Hz to 3kHz. This allows some

truly creative improvement of the signal in live situations, because this mid band covers

the range of most vocals. Listen carefully as you use these controls together to find how

particular characteristics of a vocal signal can be enhanced or reduced. Set the lower

knob to the centre-detented position when not required.

LF EQ

Turn to the right to boost low (bass) frequencies below 60Hz by up to 15dB, adding

warmth to vocals or extra punch to synths, guitars and drums. Turn to the left 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.

6 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. 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).

AUX SENDS 1 and 2 are both globally switchable between pre and post-fade (see master

section on page 20/21).

7 PAN

This control sets the amount of the channel signal feeding the Left and Right MIX buses,

allowing you to move the source smoothly across the stereo image. When the control is

turned fully left or right you are able to route the signal at unity gain to either left or right

outputs individually.
