This knob sets how much of the source signal is sent to the rest of the mixer. Too high, and

the signal will distort as it overloads the channel (shown by illumination of the PEAK LED),

and causes clipping. Too low, and the level of any background hiss will be more

noticeable and you may not be able to get enough signal level to the output of the mixer.

Setting the knob to the `U' mark gives unity gain for the LINE input.

These sends are always PRE-FADE,

PRE EQ and are unaffected by the ON

switch. They would typically be used

for Foldback or Monitor feeds, for

which it is important that the send

should be independent of the fader so

that, for instance, the mix to artists

headphones or monitor wedge is not

affected by changes in fader level.

This control sets the

amount of the channel

signal feeding the Right

and Left MIX or GROUP

outputs, allowing you to

move the source

smoothly across the

stereo image. Rotation

fully anticlockwise feeds

the signal solely to the

Left mix bus, Group 1 or

Group 3, while rotation

clockwise sweeps the

image to the right bus,

Group 2 or Group 4.

Pressing this switch reduces the level of

bass frequencies only, and is a real bonus

on a compact mixer.

Use this in live PA situations to reduce stage

rumble or `popping' from microphones.

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 250Hz

to 6kHz. This allows some truly creative improvement of the

signal in live situations, because this mid band covers the

range of most vocals. Set the lower knob to the

centre-detented position when not required.

Turn to the right to boost high

(treble) frequencies by up to

15dB, adding crispness to

cymbals, vocals and electronic

instruments. Turn to the left to

cut these frequencies by up to

15dB, reducing hiss or

over-emphasis of

high-frequency consonants,

which can occur with certain

types of microphone. Set the

knob in the centre-detented

position when a flat response

is required.

Turn to the right to boost low

(bass) frequencies 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.
