User manual SOUNDCRAFT GIGRAC BROCHURE

[. . . ] With GigRac it's no problem, thanks to the Pad switches which reduce the level of problem input signals by 20dB. 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. 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. The front panel monitoring section offers an additional range of output options to the power amplifier outputs on the rear of the unit, providing an almost limitless range of monitoring options. You can even record your performance via the dedicated RCA/phono outputs. And while you're waiting to make it big, you can relax in the knowledge that GigRac comes from Soundcraft, the name behind the live sound mixing consoles used on many of the world's major tours and festivals. GREAT SOUND MADE EASY GREAT SOUND MADE EASY Everything you need for perfect performance sound Professionally equipped input channels Soundcraft equalisation (EQ) is a legend amongst professional sound engineers and renowned the world over for its precision and musicality. [. . . ] 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. 7-band graphic EQ Studio quality effects GigRac has a total of 8 studioquality digital effects built-in, adding a professional finish to your performance. You can select from 5 reverbs, a chorus/reverb and 2 echo/delays, used to `thicken' vocal performances. 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. If you want to use an external effects processor, it's easy to connect via the FX outputs on the front panel. The FX send level controls on the channel strips can then be used in the usual way and the output of the external processor can be plugged into either a channel or the submix input. Sophisticated monitoring 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). 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. GigRac is packed with a comprehensive and flexible range of monitoring options. You can plug in a pair of headphones for precisionlistening during soundchecks and there are independent outputs for both the Main and Monitor mixes for the connection of additional `powered' speaker cabinets. A brief live-sound glossary Bus: a route by which signals from one or more sources are added and sent to one or more destinations. For example, GigRac's FX bus sends the FX send level from each channel strip to the digital effects unit and also to the FX bus out socket. Condenser microphone: requiring power from a DC voltage (phantom power), condenser microphones generally have a warm sound with a wide frequency response, making them ideal for use on vocals and acoustic instruments. This is the industry standard method and term for representing the ratio of different audio levels. Dynamic microphone: robust microphones that do not require power, so can plug into most mixers. They can handle higher sound pressure levels, making them ideal for use on drums, etc. Dynamic microphones also tend to feed back less (see below). Feedback: sound from a loudspeaker picked up by the microphone feeding it, and re-amplified out of the same loudspeaker only to return to the same microphone to be re-amplified again, and so on. Each time the signal becomes larger until the system feeds back, producing a `squeal'. This happens at particular frequencies called feedback frequencies.

Plugging Out GIGRAC 300: All the power of the GigRac 300 can be used to amplify either the Main mix (typically) or the Monitor mix (if you are using self-powered speakers for the audience). The GigRac 600 can be switched from the front panel to deliver full power to the Main mix, or split the power between the Main and Monitor mixes to power both main and monitor speakers. GIGRAC 600, CONFIG 1: The GigRac 600 incorporates two 300 Watt internal amplifiers. With the front panel amplifier assignment switch in the Up position, the Main mix is sent to both amplifiers.
