IMPOR TANT SAFETY INSTRUCTIONS IMPORT 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.
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.
• Unplug this apparatus during lightning storms or when unused for long periods of time. • Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way such as, the power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, the apparatus does not operate normally or has been dropped.
Intr oduction Introduction Firstly we’d like to thank you for choosing the Soundcraft GigRac. We hope you have many happy years together! Features 8 Microphone Inputs 48V Phantom Power for condenser microphones (Inputs 1-4 only) PAD buttons for controlling loud input signals (Inputs 1-4 only) 4 Stereo compatible inputs Treble and Bass controls Individual volume controls on each channel for Monitor level. Individual volume controls on each channel for Main level.
Quick Star Startt Guide If like most people you can’t wait to use your GigRac for the first time, then use the Quick Start Guide to get things started. The Quick Start Guide covers the following: 1. Connecting up your loudspeakers to the GigRac 2. Plugging in a vocal microphone 3. Adding Treble or Bass to the signals 4. Plugging in a guitar or stereo keyboard 5.
GigRac 600 shown.
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.
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.
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.
4. Plugging in an Acoustic Guitar, Stereo Keyboard or CD Player The GigRac will happily receive signals from instruments with 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 (2) 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 halfway.
5. Apply one of the 8 GigFX digital effects to the signals The GigRac’s GIGFX Processor (10) has a choice of 8 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.
Fr ont and Rear Panels Front Front Panel (GigRac 300 and 600) Input channel The GigRac 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 mono line level signals but will also accommodate stereo signals as well. (The GigRac 300 and 600 are mono devices and therefore any stereo signals connected will be automatically summed to mono before being output.
(2) P AD switch (Channels 1-4 only) PAD Pressing the PAD switch reduces the input level by 20dB allowing line or mic level signals that would normally be too loud for the Input stage to handle to be connected without any audible distortion. (3) Main V olume Contr ol Volume Control The Main Volume Control determines the amount of level sent from the channel to the main output mix.
(6) Bass Contr ol Control The Bass Control is set at 80Hz and allows you to either add or remove the low frequency content of the signal by 15dB. Rotating the control clockwise will ’boost’ the signal, rotating the control anticlockwise will ‘cut’ the signal. This control is useful for adding more ‘thump’ to low frequency signals such as bass guitars and kick drums but can also be used to remove unwanted rumble or boominess from signals such as vocal or instrument microphones.

(8) Main Master Volume Control This control determines the overall level that is sent to the internal amplification and to the Main Output socket.(19) (9) Mon (PHONES) Master Volume Control This control determines the overall level that is sent to the Monitor Output (Mon Output) and Phones socket. (10) Phantom 48V switch This switch turns the 48v phantom power On/Off for the 3 pin XLR sockets on channels 1-4. When the switch is turned On the red LED will illuminate.
(13) Power LED The red Power LED illuminates when the GigRac is switched on. (14) Main to Amp 1/Mon to Amp 2 - Main to Amp 1/Main to Amp 2 switch (GigRac 600 only) This switch determines which signals are sent to Amp 1/Speaker Output 1 and Amp 2/Speaker Output 2. The Choices are: Main to Amp 1/Main to Amp 2 – The Main Mix is sent to both Speaker Output 1 and Speaker Output 2.
(15) Amp Clip LED The red Amp Clip LED illuminates when the input level to the internal amplifier is too high. It is acceptable for this LED to come on momentarily every now and then but the Main or Monitor Master Volume (depending on which mode has been selected: see (14) above) should be turned down if the Amp Clip LED illuminates consistently.
be used to send the Main Mix to another amplifier or powered speaker or alternatively it can be used to send a ‘submix’ to another mixer’s input channel or another recording device. (20) Mon Output The Mon Output carries the Monitor Mix signal derived from the Mon controls on each channel. The Mon output level is controlled by the Mon Master Volume control.(9) This output is used mainly to send the Mon Mix signal to an on stage fold back speaker system of some kind.
Master Section GigRac 300 (8) Main Master Volume Control This control determines the overall level that is sent to the internal amplification and to the Main Output socket. (9) Monitor Master Volume Control (Mon Master Volume Control) This control determines the overall level that is sent to the Monitor Output (Mon Output) and Phones socket.
(10) Phantom 48V switch This switch turns the 48v phantom power On/Off for the 3 pin XLR sockets on channels 1-4. When the switch is turned On the red LED will illuminate. 48V phantom power is used to power condenser microphones and DI boxes. NB! To avoid the possible damage to your loudspeakers, make sure that the Main and Monitor Master Volume controls are turned downfully before switching on the 48V phantom power. (11) Graphic Equaliser The Graphic Equaliser is divided into 7 frequency bands.
(14) Amp Clip LED The red Amp Clip LED illuminates when the input level to the internal amplifier is too high. It is acceptable for this LED to come on momentarily every now and then but the Main or Monitor Master Volume (depending on which mode has been selected – see (12) above) should be turned down if the Amp Clip LED illuminates consistently.
