User manual ALLEN & HEATH GS-R24 BLOCK DIAGRAM

[. . . ] The equipment has not been subject to misuse either intended or accidental, neglect, or alteration other than as described in the User Guide or Service Manual, or approved by ALLEN&HEATH. Any necessary adjustment, alteration or repair has been carried out by ALLEN&HEATH or its authorised agent. The defective unit is to be returned carriage prepaid to ALLEN&HEATH or its authorised agent with proof of purchase. Check with your ALLEN&HEATH agent for any additional warranty which may apply. This product complies with the European Electromagnetic Compatibility directives 89/336/EEC & 92/31/EEC and the European Low Voltage Directives 73/23/EEC & 93/68/EEC. This product has been tested to EN55103 Parts 1 & 2 1996 for use in Environments E1, E2, E3, and E4 to demonstrate compliance with the protection requirements in the European EMC directive 89/336/EEC. [. . . ] A front panel recessed `mode' switch determines the source to the AB output. This may be set to follow the console monitor system and therefore feed an independent local stereo monitor or even engineers wedge speaker. When set to follow the LR mix, the factory default source is taken post LR fader. An internal option jumper is available to change this to pre LR fader. The unique AB output feature provides the MixWizard with a host of possibilities. . . independent 2-track recording feed, broadcast feed, zone and delay fill feeds, local monitor, engineers wedge monitor and more. AUX OUT 1-6 Each aux send is available on an impedance balanced TRS jack operating at -2dBu line level. An internal option is available to fit a balanced line driver IC to provide an electronically balanced output operating at +4dBu. Note that it is not usual to require this option as the impedance balanced standard drive provides significant interference rejection when feeding balanced equipment inputs. The aux sends are typically used to feed stage monitors, effects devices such as reverb and delay, and for special mix requirements. MIDI IN A standard 5-pin DIN MIDI input socket is provided. This is used with external MIDI equipment or a MIDI equipped PC to control the built-in effects processor. Free software can be downloaded from the Allen & Heath web site for PC editing of the parameters via MIDI. FOOTSWITCH Mutes and unmutes the ST5 (ST1) effects return channel, ideal for bypassing the effects between songs. Note that this affects the internal processor and also any external effects device that may be plugged in to these return inputs. The red PK indicator half lights to show that PFL has been selected on that channel. Selecting more than one PFL at the same time mixes those signals together in the monitor. PEAK The red indicator illuminates when the channel pre-fade signal is within 5dB of clipping. This gives you enough warning to reduce the GAIN control before you hear signal distortion. The green signal presence indicator lights when the channel pre-fade signal is greater than -12dBu. 5 0 5 10 SIGNAL FADER 20 30 Controls the channel level feeding the main LR mix and post-fade aux sends. It also affects the direct output if this has been set to post-fade using the internal option jumpers. The fader provides +10dB maximum boost above its normal unity gain 0dB position. Important note on setting channel levels: Use PFL to set the GAIN controls for correct signal level through each channel. These are typically operated around their -20 to 0 positions according to the mix. We do not recommend setting the faders to `0' and mixing using the GAIN controls.

For example, you could mix two sound effects playback devices or two reverb returns together into one channel. [. . . ] Lock the connector pod in the required position using the securing screws. Check carefully that all channel jumpers are correctly set as required. We recommend that you write the repositioned jumper settings on a label and adhere this to the rear panel. This would provide a helpful reference to other users of the console.
