The units are capable of operating at either 230V AC or 115V AC
mains voltages ±10%.
• REPLACING MAINS FUSE
Remove the mains lead from the connector . Use a small screwdriver
to unscrew the fuse carrier from its location to the left of the
mains power connector. Check the fuse is of the correct type and
value and replace if necessary; also check that the voltage rating
as marked on the rear panel is correct for the mains supply level
before switching the unit ON again.

with the coloured markings identifying the terminals in your plug,
proceed as follows:
The wire which is coloured Green and Y ellow must be connected
to the terminal in the plug which is marked with the letter E
or by the earth / ground symbol:
The wire which is coloured Blue or White must be connected
to the terminal in the plug which is marked with the letter N.
The wire which is coloured Brown or Black must be connected
to the terminal in the plug which is marked with the letter L.
Ensure that these colour codings are followed carefully in
the event of the plug being changed.

The GigRac case.
Y our GigRac is cased in a structural foam copolymer polypropylene resin,
which gives an optimum combination of strength and impact resistance.
This material also helps to keep the shell in good condition as it very
resistant to dents and scratches.
The nature of the moulding process leaves the irregular streaky surface
finish that gives the GigRac its tough and unique look.

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 with Neutrik Speakon connectors then use
the Speakon connectors on the rear of the GigRac. Alternatively if you
have cables equipped with jack plugs then use the jack sockets on the
rear of the GigRac.
Note: Because the GigRac 300 and GigRac 600 are
mono mixers there is no difference between the signals
sent to the Left or Right speakers i.e. both speakers
will receive the same signal equally all of the time.
Make sure that the Main Master V olume control (1) is turned fully down
Now switch the GigRac on using the Power switch 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 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.
(The inputs on the GigRac can receive either 3-Pin XLR or standard Jack
connectors.)
10
Turn the Main Master Volume control (1) up to about half-way.
Now gradually turn up the Main Volume control (2) on the microphone
channel you have chosen to use. You should now 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 (4)
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
power you will need to switch on the 48V phantom power switch (3)
located to the left of the Graphic Equaliser . Before doing this mak e sure
that the Main Volume control (2) on the chosen channel is turned fully
off to avoid causing an unpleasant sound that might damage your
speakers.

3. Adding Treble or Bass to the signal
The GigRac offers simple Treble and Bass control for changing the tone
of the signal.
Treble (5)
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 clockwise will boost the treble frequencies
making the signal sound brighter. T urning it anti-clockwise will 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.
Bass (6)
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. T urning it clockwise will boost the Bass frequencies
making the signal sound punchier and more ‘bassy’. Turning it anticlockwise will 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.
