Along the CHANNEL STRIP , controls adjust the GAIN
(to get the best quality signal and avoid overload)
and the FIL TER and EQUALISER change the
frequency response to clean up or enhance the
sound.
The AUX SENDS let you set up a separate mix for
ar tists FOLDBACK or to add EFFECTS PROCESSORS.
P AN swings the signal to the LEFT or RIGHT of the
stereo MIX output.
The final MIX OUTPUT is taken from here to a suitable power
amplifier and loudspeakers or to record the mix to a tape machine.
Y o u can listen to the signal on loudspeakers by taking the signal
from the MONITOR OUTPUTS via a suitable power amplifier .
The CHANNEL F ADER sets the level of the channel
signal which is fed to the Master Section and adjusts
the sound BALANCE between the dif ferent sources.
The MASTER F ADERS set the level of the
combined signal from all of the input channels
going to the amps and speakers.

Accepts XLR-type connectors and is
designed to suit a wide range of
BALANCED or UNBALANCED signals.
Professional dynamic, condenser or
ribbon mics are best because these will
be LOW IMPEDANCE. Y o u can use
low-cost HIGH IMPEDANCE mics, but
the level of background noise will be
higher .
If you turn the PHANTOM POWER on
(top right-hand side of the mixer) the
socket provides a suitable powering
voltage for professional condenser mics.
Unplug any mics if you want to use the
LINE Input. Set the input level using the
GAIN knob.
➭
See page 11
Accepts 3-pole `A ' gauge (TRS) jacks. Use
this input for sources other than mics, such
as keyboards, drum machines, synths, tape
machines or guitars. The input is
BALANCED for low noise and immunity
from inter ference, but you can use
UNBALANCED sources by wiring up the
jacks as shown on page 11, although you
should then keep cable lengths as shor t a s
possible. Unplug anything in the MIC input
if you want to use this socket. Set the input
level using the GAIN knob.

This knob sets how much of the source
signal is sent to the rest of the mixer .
T o o high, and the signal will distor t a s
it overloads the channel.
T o o 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 . See `Initial Setting Up' to
learn how to set the GAIN correctly .

See page 11
Pressing this switch reduces the level of bass
frequencies only . This feature is ver y rare for such a
small mixer .
Use this in live P A situations to reduce stage rumble or
`popping' from microphones.
➭
See page 11
T urn to the right to boost low (bass) frequencies, adding war mth to
vocals or extra punch to synths, guitars and drums. T urn to the left to
reduce hum, stage rumble or improve a mushy sound. Set the knob to
the centre-detented position for a neutral EQ response.
3
T urn to the right to boost high (treble) frequencies,
adding crispness to cymbals, vocals and
electronic instruments. T urn to the left to cut these
frequencies, reducing hiss or distor ted consonants
which can occur with cer tain types of microphone.
Set the knob in the centre-detented position for a
neutral EQ response.
There are two knobs which work together to form a SWEPT MID EQ. The lower knob provides boost and cut, just
like the HF EQ knob, but the frequency at which this occurs is set by the upper knob over a wide range. 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 par ticular characteristics of a vocal
signal can be enhanced or reduced. Set the lower knob to the centre-detented position for a neutral EQ
response.
This is used to set up a separate mix for FOLDBACK, EFFECTS or recording, and the combination
of all the Aux 1 Sends is mixed to the Aux 1 Output. For Ef fects it is useful for this to fade up and
down with the F ADER (this is called POST -F ADE), but for Foldback or Monitor feeds it is impor tant
for the send to be independent of the F ADER (this is called PRE-F ADE). The Master Section AUX1
PRE switch allows you to chose pre- or post-fade across the whole mixer as required. Leave the
knob turned down when not in use.
The Equaliser (EQ) allows fine manipulation of the sound, par ticularly
to improve the sound in live P A applications where the original signal
is often far from ideal.
There are three sections (HF , MID & LF) giving the sor t o f control
usually only found on much larger mixers. The EQ knobs can have a
dramatic ef fect on the sound, so use them sparingly and listen carefully
to the result.

This is similar to the Aux Send 1
control, but is always POST -F ADE.
The linear F ADER gives you smooth control of the
overall signal level in the channel strip, allowing
precise balancing of the various source signals
being mixed to the Master Section. It is impor tant to
set up the input GAIN correctly to give full travel
(i.e. maximum control) on the fader . See the `Initial
Setting Up' section on page 10 for help in setting a
suitable signal level.
➭
See page 12
This control sets the amount of the channel signal feeding the
Right and Left MIX outputs, allowing you to move the source
smoothly across the stereo image. When the control is
turned fully right or left you are able to place the signal to
either left or right of the output.
➭
See page 12
When the PFL (Pre-Fade-Listen) switch is pressed the pre-fade
channel signal is fed to the monitor output or headphones,
replacing the normal source (either Mix or T ape Return).
Y o u use this switch to listen to a channel signal without
af fecting the mixer outputs, to check the signal quality or
simply to check that it is there! Y o u would also use the PFL
switch to set the input GAIN, and this is explained on page
10 - `Initial Setting Up'.

Accept 3-pole `A ' gauge (TRS) jacks. Use
these inputs for sources such as
keyboards, drum machines, synths, tape
machines or as returns from processing
units. The inputs are BALANCED for low
noise and immunity from inter ference, but
you can use UNBALANCED sources by
wiring up the jacks as shown later in this
guide, although you should then keep
cable lengths as shor t a s possible.

See page 13
Most professional equipment uses input and output
levels of +4dBu, but semi-professional tape machines
use a low level of -10dBV (or hi-fi systems 100mV).
This switch allows you to match the stereo input to
either standard. Release the switch for +4dBu, or
press for -10dBV .
T urn to the right to boost high (treble) frequencies,
adding crispness to percussion from drum machines,
synths and electronic instruments. T urn to the left to cut
these frequencies, reducing hiss or excessive
brilliance. Set the knob in the centre-detented position
when not required.

This control sets the amount of the channel signal feeding the Right and Left MIX
outputs, allowing you to balance the source in the stereo image. When the
control is turned fully right or left you feed only that side of the signal to the mix.

When the PFL (Pre-Fade-Listen) switch is pressed a
mono sum of the pre-fade channel signal is fed to the
monitor output or headphones, replacing the normal
source (either Mix or T ape Return).
Y o u use this switch to listen to a channel signal without
af fecting the mixer outputs, to check the signal quality
or simply to check that it is there!
