Quick Start Guide Key

10
1. Connecting up your loudspeakers to the GigRac
Note: Make sure your GigRac is not powered up. This
is very important to prevent any damage to either the
GigRac or your loudspeakers!
Using good quality speaker cables connect the loudspeakers to the
Speaker outputs on the rear of the GigRac.
If you have cables equipped ith Neutrik Speakon® connectors then use
the Speakon® connectors on the rear of the GigRac. Alternatively if
you have cables equipped ith jack plugs then use the jack sockets on
the rear of the GigRac.
Make sure that the Main Master Volume control (1 - see the key on
page 9) and the Monitor (Mon) Master Volume control (2) are turned
fully do n.
Decide if you ant to configure the 2 internal amplifiers to ork as a
stereo pair, or mono mix and monitor. Set the amplifier source select
s itch (3) as desired. It is assumed in these quick start instructions
that you have configured the amps as a stereo pair.
No s itch the GigRac on using the Po er s itch on the rear of the
unit.
2. Plugging in a vocal microphone
Note: Before connecting a microphone to channels 1-4,
make sure that the 48V phantom power switch (4) is
switched off (The red LED should not be illuminated).
Connect the microphone cable to one of the first four inputs on the
front of the GigRac (5).
(The inputs on the GigRac can receive either 3-Pin XLR or standard
Jack connectors.)

11
Turn the Main Master Volume control (1) up to about half- ay.
No gradually turn up the Main Volume control (6) on the microphone
channel you have chosen to use. You should no hear the microphone
signal appearing in the loudspeakers as you begin to speak.
You should also be able to see activity on the Output Meter (7).
Assuming that you have configured the amps as a stereo pair, you can
pan the microphone signal from left to right using the Pan control (8).
Note: The XLR input on channels 1 - 4 is very sensitive.
Depending on your microphone or your application, you
may need to press the PAD button to prevent
distortion occurring; dont worry, this is perfectly
normal.
Note: Be careful not to point the microphone at the
loudspeakers or you could accidentally create
unpleasant feedback sounds.
A note on Condenser Microphones
If your microphone is a condenser microphone that requires phantom
po er you ill need to s itch on the 48V phantom po er s itch (4)
located to the left of the Graphic Equaliser. Before doing this make sure
that the Main Volume control (6) on the chosen channel is turned fully
off to avoid causing an unpleasant sound that might damage your
speakers.

12
3. Adding Treble, Mid or Bass to the signal
The GigRac offers Treble, Mid and Bass control for changing the tone of
the signal.
Tre le (9)
To add or remove some brightness or sparkle to or from a signal, use
the Treble control. In the center click position (0) the Treble control
has no effect. Turning it clock ise ill boost the treble frequencies
making the signal sound brighter. Turning it anti-clock ise ill have the
opposite effect by removing the treble frequencies and making the signal
sound less bright.
The Treble control is handy for adding some sparkle for example to an
acoustic guitar, or for reducing the s sound from sibilant vocals.
Mid (10)
Short for Midrange this knob can be used to cut or boost important
fundamental frequencies. In the centre Click position the Mid control
has no effect. Turning it clock ise ill boost the mid frequencies adding
body to signals. This is particularly effective on snare drums and
percussive instruments. Turning it anti-clock ise ill have the opposite
effect and is useful for removing boxy resonant frequencies from
acoustic guitars and other signals.
Bass (11)
To add some bass thump to a signal or remove some boominess or
rumble, use the Bass control. In the center click position (0) the Bass
control has no effect. Turning it clock ise ill boost the Bass frequencies
making the signal sound punchier and more bassy. Turning it anti-
clock ise ill have the opposite effect by removing the bass frequencies
and making the signal sound less boomy.
The Bass control is useful for making a bass drum sound punchier, or
alternatively could be used for reducing explosive b and p sounds
from a vocal signal.

13
4. Plugging in an Acoustic Guitar, Stereo Keyboard or CD
Player
The GigRac ill happily receive signals from instruments ith either mono
or stereo outputs such as guitars (Mono) or stereo keyboards and CD
Players (Stereo).
Before plugging in, make sure the Main Volume control (6) for the chosen
channel is turned fully off to avoid accidental damage to your speakers.
Acoustic Guitars
Set the Main Master Volume control (1) to about half ay.
Make sure the Main Volume control (6) on the channel you are about to
use is turned fully do n.
Plug the guitar lead into the jack socket in the center of the combination
input socket (5) on the channel of your choice. Turn up the volume
control on your guitar to about half ay, and then gradually turn up the
Main Volume control (6) until you hear the guitar signal appearing in the
loudspeakers.You should also see activiity on the Main Output meter
(7).
Stereo Key oards and CD Players
The GigRac offers four channels that can receive stereo inputs. T o of
these channels are equipped ith RCA/Phono connectors (Channel 5
and 6) (12) and t o ith Jack connectors (Channels 7 and 8) (13).
Connect up the Left and Right outputs of your CD player or Cassette
deck to the Left and Right RCA/Phono inputs on either Channel 5 or 6 of
the GigRac. Turn up the Main Master Volume control (1) to about half ay,
and then turn up the Main Volume control (6) on the chosen channel
until you hear the signal appearing in the loudspeakers.
Connect up the Left and Right outputs of your Stereo Keyboard to the
Left and Right Jack inputs on either Channel 7 or 8 of the GigRac. Set
the volume control of your keyboard to about half ay. Turn up the Main
Master Volume control (1) to about half ay, and then turn up the Main
Volume control (6) on the chosen channel until you hear the signal
appearing in the loudspeakers.
You may no use the Treble, Mid and Bass controls as mentioned above
to change the tone of the signals.

14
5. Apply one of the 10 GigFX digital effects to the signals
The GigRacs GIGFX Processor (14) has a choice of 10 studio quality
digital effects that can be added to any individual or group of signals
running through the mixer. Usually vocals require some digital reverb or
echo to be added to them in order to create a more spatial sound that
is pleasing to the listener.
Make sure the effects On button (15) is selected.
To try this out simply select one of the 10 GigFX presets, such as Hall
Reverb, using the selector knob (16).
Turn the FX to Main control (17) to about half ay and then gradually
turn up the individual FX send control (18) on the channel you ish to
add the effect to. As you turn up the FX send level you should hear the
signal change.
By pressing the effects On (15) s itch to the off position you can
compare the original dry signal ith the et effect signal.
You can no turn the selector knob (16) to select different types of
effects for comparative purposes.
A Note on Channel Use
Channels 1-4 are the most sensitive. It is better to use these channels
for microphones (particularly if your microphones are fitted ith jack
plugs), and guitars ith passive pickups. It is likely that you ill need to
have the pad buttons pressed in if you use mics fitted ith XLRs.
Channels 5-8 are less sensitive, they are ideal for line-level devices such
as keyboards, CD players and tape players. They ill also ork ith
guitars ith active pickups. Microphones fitted ith XLRs ill also ork
(unless they need phantom po er).

Input channel
The GigRac 1000st has a total of 8 channels. Channels 1-4 are designed
to handle mono microphone or mono line level signals only. Channels 5-8
are designed to handle mono microphone and stereo line level signals
but ill also accommodate mono line-level signals as ell.
(1) Input Connector
This connector is a combination Jack/3 Pin XLR connector and can receive
any of the follo ing types of input connectors:
Microphone cables ith Jack connectors
Microphone cables ith 3 pin XLR connectors
Line input cables ith Jack connectors (e.g. guitars, keyboards
etc.)
Line input cables ith 3 pin XLR connectors.

16
(2) PAD switch (Channels 1-4 only)
Pressing the PAD s itch reduces the input level by 20dB allo ing line or
mic level signals that ould normally be too loud for the Input stage to
handle to be connected ithout any audible distortion.
(3) Main Volume Control
The Main Volume Control determines the amount of level sent from the
channel to the main output mix.
This allo s each channels relative volume level to be blended together
to create the final mix hose overall level is then controlled by the Main
Master Volume control (10 - see the master section).
(4) Mon Volume Control
The Monitor (Mon) Volume Control determines the amount of level sent
from the channel to the Monitor (Mon) Output (23).
This allo s each channels relative volume level to be blended together
to create a separate monitor mix hose overall level is then controlled
by the Mon Master Volume control (11 - see the master section). This
feature is used mainly for creating a foldback mix for the musicians and
ould normally be sent to a monitor speaker ith its o n amplifier. (This
could also be used for creating a headphone mix).
The Mon Volume Control operates independent of the Main Volume Control
and ill therefore not be affected if the Main Volume Control is turned
up or do n. (For the more technically minded, the signal is sourced
Pre-Fader and Post EQ, see the block diagram for signal routing details.)
(5) PAN/Balance Control
This allo s you to position the signal ithin the stereo image or, in the
case of stereo signals, to balance the level of the signals bet een the L
and R speakers.
(6) FX Control
The FX Control determines the amount of level sent from the channel to
the GigFX digital effects processor and also to the FX Bus output
connector (24).
This allo s each channels relative level to be blended together to create
a separate effects mix hose overall level is then controlled by the FX
to Main (28 - see the master section) and FX to Mon (29).
