CAUTIONS
•To avoid the risk of fire, replace the mains fuse only with the correct
type and value fuse, as marked on the rear of the product.
•ATTENTION: - Afin de réduire le risque de feu remplacer seulement avec
fusible de même type.
•MAINS VOLTAGE SELECTION
This setting is NOT User Adjustable.
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.
If the mains fuse fails repeatedly this may be because an electrical
safety hazard exists. The unit must be taken out of service and
referred to the Soundcraft dealer from where the equipment was
purchased.
•THIS UNIT MUST BE EARTHED
Under no circumstances should the mains earth be disconnected
from the mains lead.
•ATTENTION: - Cet appareil doit être branché à la terre.
The wires in the mains lead are coloured in accordance with the following
code:
UK & EU US & CAN
Earth / Ground: Green and Yellow Green and Yellow
Neutral: Blue White
Live: Brown Black

5
As the colours of the wires in the mains lead may not correspond
with the coloured markings identifying the terminals in your plug,
proceed as follows:
The wire which is coloured Green and Yellow 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.
Your 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.

3. Adding Treble or Bass to the signals

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 Volume 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.)
