At the heart of live sound
PROFESSIONAL POWERED MIXER
GIGRAC 300 / GIGRAC 600
Even if you’ve never touched a PA
system before, you’ll be
creating a great live sound
for you and your band in
minutes with GigRac.
Packed with professional
features like combined jack/XLR
inputs, precision mic preamps,
superbly musical equalisation, studio quality digital effects, graphic EQ
and independent Main and Monitor mixes, GigRac is also refreshingly
easy to set up, leaving you free to concentrate on your performance.
With GigRac, the amplifier is built-in, with both 300 and 2 x 300 Watt
versions available. Just plug in your mics, instruments, speakers and
monitors, and you’re ready to go.
And while you’re waiting to make it
big, you can relax in the knowledge
that GigRac comes from Soundcraft, the
name behind the live sound mixing consoles used on
many of the world’s major tours and festivals.
The switchable 7-band
graphic equaliser
section lets you
optimise the tonal
quality of your mix to
suit the acoustics of
the venue.
Just like a professional
mixing console, +48V
phantom power on
channels 1-4 enables
you to use high quality
condenser microphones
with GigRac.
GigRac has eight
high-quality digital
effects
programmes built-
in, ranging from
stunning reverbs to
fat delays.

No experience necessary
GREAT SOUND MADE EASY
The front panel monitoring
section offers an additional
range of output options to the
power amplifier outputs on the
rear of the unit, providing an
almost limitless range of
monitoring options. You can even
record your performance via the
dedicated RCA/phono outputs.
Simply connect a footswitch and it’s
easy to turn GigRac effects On and
Off during the performance. And the
FX bus output gives you the flexibility
to connect an external effects
processor which can then be
plugged back into a spare channel
or into the submix input.
Stereo RCA/phono
inputs make it easy to
plug in a CD, MiniDisc or
MP3 player.
You might want your audience to
hear your voice bathed in digital
reverb, while you hear it ‘dry’ through
your monitors. That’s why GigRac’s
digital effects controls enable you to
turn the effects On or Off, and to
add different amounts of effects to
the Main and Monitor mixes.
Master Main and
Monitor level controls
provide independent
control over the
volume your audience
hears, and the volume
of your own monitor
mix on stage.
Stereo jack inputs
allow connection of
stereo keyboards,
samplers, sound
modules and MIDI file
players, along with
other audio equipment
such as effects
processors.
10-segment precision LED
metering gives you a clear
indication of how hard the
amplifier is working,
allowing you to achieve the
best results.
Amplifier overload
warning LED(s) enable
you to precisely control
the volume of your
performance.
And protection circuitry
means you’ll never have
to worry about distortion.
The Monitor volume
controls can be used to
create an independent
headphone mix.
The amplifier assignment
switch featured on the
GigRac 600 provides an
additional level of flexibility
with the option to power
both the Main and Monitor
mixes with the internal
power amplifiers.
Comprehensive channel controls
include Bass and Treble for tone
shaping, an FX send to control the
amount of signal sent to the digital FX
processor, and separate Main and
Monitor volume controls which allow
you to create independent band and
audience mixes.
GigRac lid with storage space
for microphones and cables.
GREAT SOUND MADE EASY
Some high-output microphones
and other devices can overload a
mixer’s inputs, causing distortion.
With GigRac it’s no problem,
thanks to the Pad switches which
reduce the level of problem input
signals by 20dB.
Combination jack/XLR sockets
make it possible to plug virtually
any type of microphone into
GigRac, along with electric
guitars, basses, electro-acoustic
guitars and other ‘electric’
instruments.
And these inputs are balanced,
just like a studio mixing console,
so noise and interference are
kept to a minimum.
Creating a great live performance sound just got easy.
Available in two models (GigRac 300 and GigRac 600), GigRac combines
a fully-featured 8 channel mixer with studio-quality digital effects and potent
power amplification in a portable package that sets up in minutes.
GigRac is built into a tough, portable, protective case,
and it can also be rack-mounted.

Everything you need for perfect performance sound
Soundcraft equalisation (EQ) is a legend amongst
professional sound engineers and renowned the
world over for its precision and musicality. At the top
of all 8 GigRac input channels you’ll find a classic
Soundcraft 2-band EQ section comprising of treble
and bass rotary controls, allowing sophisticated tone
shaping of the microphone or instrument connected.
Next comes an FX control, used to set the signal level
sent from each channel to the GigRac’s digital effects
processor (see Studio Quality Effects). The higher the
FX send level, the more of the effect is added to the
sound of that channel. For example, you may want a
lot of reverb on the vocal mics plugged into channels
1 and 2, less on the vocal mics plugged into 3 and
4, and less still on the instruments plugged into the
remaining channels. With GigRac, you’re in control.
Beneath the FX controls are the blue and red Monitor
and Main channel level controls. These control the
individual volume levels of all eight channels in 2
separate overall mixes: Monitor being what you and
the band hear on stage via your monitor speakers
and Main being what the audience hears via the
main speakers. It’s important to have independent
Monitor and Main mixes as performers often need to
hear certain elements of the mix louder (for example
a keyboard or main instrument for reference),
whereas the audience would require a balanced mix.
The overall volume level of the Monitor and Main
mixes is controlled via the master volume controls to
the right of the channel strips.
All 8 GigRac input channels have combined balanced
jack/XLR input sockets to accommodate the widest
possible range of microphones and instruments, and
to minimise distortion and noise. The Pad switch at
the bottom of channels 1 to 4 is used to reduce the
level of particularly high input signals which could
cause distortion by overloading the input.
Channels 5 and 6 of the
GigRac feature alternative
stereo RCA/phono inputs
beneath the combined
XLR/jack connector, making
it easy to plug in a CD, MD, MP3 or MIDI file player.
Perfect for playing pre-recorded backing tracks or
music before and after your performance, this facility
also makes GigRac ideal for use in a wide variety of
other applications including fitness clubs, hotels,
outdoor events, etc.
Channels 7 and 8 have an additional
single jack input designed to be used
in conjunction with the combined
XLR/jack connector. This allows direct
connection of stereo keyboards, samplers and other
audio devices.
Even with the same setup, a performance can sound very different
from one venue to the next. The way in which sound waves reflect and
interact with surfaces and objects within a room (the acoustics)
change the tonal quality of the overall sound, boosting some
frequencies (sometimes to the point of feedback) and reducing others.
That’s why the GigRac is equipped with a graphic equaliser, designed
by the Soundcraft sister-company and world leaders in professional
signal processing, BSS Audio. The graphic EQ enables the operator
to boost and cut frequencies at 7 points to ‘tune’ the overall sound
to suit the acoustics of the particular venue.
It’s a process that professional sound engineers are familiar with as
they tour from venue to venue. And because GigRac’s so easy to use,
a little practise is all you’ll need to achieve professional results too.
GigRac has a total of 8 studio-
quality digital effects
built-in, adding a
professional finish to
your performance.
You can select
from 5 reverbs,
a chorus/reverb
and 2
echo/delays,
used to
‘thicken’ vocal
performances.
Crucially, GigRac
allows the digital
effects to be added
individually to the Main
and the Monitor mixes, so you
can hear the mix ‘dry’ on
headphones and via monitors, while the audience hears the Main
mix complete with stunning digital effects. And by connecting a
footswitch, it’s possible to turn the effects On and Off during a
performance.
If you want to use an external effects processor, it’s easy to connect
via the FX outputs on the front panel. The FX send level controls on
the channel strips can then be used in the usual way and the output
of the external processor can be plugged into either a channel or the
submix input.
To help achieve optimum volume levels, the
GigRac uses a precision, 10-segment, front
panel LED meter display, just as you’d find on a
professional live sound mixing console. And a
further indication that the volume level is too
high is provided by an amplifier overload
warning LED(s).
A pair of RCA/phono outputs are perfect for
recording the Main mix onto an external DAT or
CD recorder, or for recording your performance
on computer using an appropriately-equipped
soundcard.
GigRac is packed with a comprehensive and
flexible range of monitoring options. You can
plug in a pair of headphones for precision-
listening during soundchecks and there are
independent outputs for both the Main and
Monitor mixes for the connection of additional
‘powered’ speaker cabinets.
A brief live-sound glossary
Bus: a route by which signals from one or more sources are added
and sent to one or more destinations. For example, GigRac’s FX bus
sends the FX send level from each channel strip to the digital
effects unit and also to the FX bus out socket.
Condenser microphone: requiring power from a DC voltage
(phantom power), condenser microphones generally have a warm
sound with a wide frequency response, making them ideal for use
on vocals and acoustic instruments.
dB: abbreviation for ‘decibel’. This is the industry standard method
and term for representing the ratio of different audio levels.
Dynamic microphone: robust microphones that do not require
power, so can plug into most mixers. They can handle higher sound
pressure levels, making them ideal for use on drums, etc. Dynamic
microphones also tend to feed back less (see below).
Feedback: sound from a loudspeaker picked up by the microphone
feeding it, and re-amplified out of the same loudspeaker only to
return to the same microphone to be re-amplified again, and so on.
Each time the signal becomes larger until the system feeds back,
producing a ‘squeal’. This happens at particular frequencies called
feedback frequencies.
Phantom power: a system of providing +48 volt power from the
mixer to a condenser microphone, sharing the same cable as the
audio signal.
Reverb: short for reverberation. The sound remaining in a room after
the source signal is stopped. It is caused by the sound reflecting
from the walls and surfaces in the room.
Speakon: a registered trademark of Neutrik for their original design
loudspeaker connector, now considered an industry standard.
XLR: an industry standard, 3-pin connector, used extensively in
professional audio.
