PROFESSIONAL POWERED MIXER
GIGRAC 600 / GIGRAC 1000st
GREAT SOUND MADE EASY
Comprehensive channel controls include 3-band equalisation
(GigRac 600 2-band only), an FX send to control the amount of
signal sent to the digital FX processor, Pan control (GigRac 1000st
only) and separate Main and Monitor volume controls which allow
you to create independent band and audience mixes.
Creating a great live performance sound just got easy.
Available in two models (GigRac 600 and the stereo GigRac 1000st),
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 600
GigRac 1000st (stereo)
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.
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.
GREAT SOUND MADE EASY
Stereo RCA/phono inputs make it easy
to plug in a CD, MiniDisc or MP3 player.
Stereo jack inputs allow connection of
stereo keyboards, samplers, sound
modules and MIDI file players, along
with other audio equipment such as
effects processors.
The amplifier assignment switch
provides an additional level of
flexibility with the option to power
both the Main and Monitor mixes
with the internal power amplifiers.
Just like a professional mixing console,
+48V phantom power on channels 1-4
enables you to use high quality condenser
microphones with GigRac.
Dual 7-band graphic equalisers on the
GigRac 1000st and single 7-band
graphic on the GigRac 600 let you
optimise the tonal quality of your mix to
suit the acoustics of the venue.

The front panel monitoring section
offers an additional range of

the unit, providing an almost
limitless range of monitoring

performance via the dedicated
RCA/phono outputs.

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.
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.
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.
In addition, the GigRac 1000st (only) features playback
returns for use in recording applications.

Everything you need for perfect performance so
Professionally equipped input channels
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 classic
Soundcraft 3-band (GigRac 1000st)
or 2-band (GigRac 600) EQ
sections, 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.
The GigRac 1000st channels have

separate overall mixes: Monitor being what you and the
band hear on stage via your monitor speakers and Main
GigRac 1000st
7-band graphic EQ
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.
All channel inputs on the GigRac 1000st can be muted
in ‘Standby’ mode, so the PA is silent when unused (see
Playback input).
GREAT SOUND MADE EASY
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
graphic equalisers (single in the Gigrac
600, dual in the GigRac 1000st),
designed by the Soundcraft sistercompany 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 practice is all you’ll need to achieve professional results too.

Studio quality effects
Sophisticated monitoring
GigRac 1000st has a total of
10 studio-quality digital
effects built-in, (8 in
the GigRac 600)
adding a
professional
finish to your
performance.
You can select
between
reverbs,
chorus/reverbs
and echo/
delays, used to
‘thicken’ vocal
performances.
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).
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.
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 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. In addition, the GigRac 1000st (only)
features a stereo playback return. This Playback
input is active while Mic/Line inputs are in
standby, allowing interval music to still be played.
