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. This warranty does not cover fader wear and tear. The defective unit is to be returned carriage prepaid to ALLEN&HEATH or its authorised agent with proof of purchase. [. . . ] Shorting a TS or TRS jack tip to sleeve turns the mute on. SYS-LINK II OPTION A blank plate is fitted here as standard. The Sys-Link II option kit is available from Allen & Heath. Refer to OPTIONS later in this guide. 14 WZ316:2 and 12:2 User Guide The MONO Input Channel +48V Switches +48VDC to the channel input XLR for powering microphones or DI boxes that need phantom power. The power is current limited through 6k8 ohm resistors to pins 2 and 3. WARNING: Do not connect unbalanced sources or cables to inputs with phantom power selected. To avoid loud clicks always mute the channel before switching +48V on or off and when plugging or unplugging microphones. +48V PAD 40 50 60 40 (LINE) 0 20 30 GAIN - 10 10 HPF HF -15 1k 700 500Hz 3k +15 4k 6k 15k HM PAD (LINE) Press this switch to select the channel TRS jack LINE -15 70 180 +15 250 400 1k 45 35Hz LM LF -15 +15 input. Release the switch to select the XLR MIC input. With nothing plugged into the line input the switch therefore becomes a PAD for the mic XLR. It attenuates the input signal by 20dB for connection to high level microphone or line sources. -15 +15 GAIN Adjusts the input sensitivity to match the connected source to the internal 0dBu operating level of the channel. Provides a variable 50dB range from +10 to +60dB gain (mic), or -10 to +40dB (line, pad selected). The gain should be set using PFL so that the console meters average `0' with loudest moments lighting `+6'. You can change this by repositioning the internal option jumpers. PAN Positions the channel signal between L and R in the stereo mix. The centre position (mono image) is detented for quick resetting. the feed to the LR mix, pre and post-fade aux sends and direct output, but does not affect the insert send. The red indicator lights when the channel is muted. OO +6 POST PRE AUX 5 OO +6 MUTE When pressed the channel signal is turned off. This affects AUX 6 OO +6 POST = PAN L R MUTE PK! PFL SIG 10 PFL Press PFL to listen to the pre-fade channel signal in the headphones or AB monitor (if configured) without affecting the main outputs. The console main LR meters are interrupted with the channel signal. 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. [. . . ] You can change these settings for different combinations of pre/post or switched auxes by repositioning the links. Refer to the system block diagram to explore the possibilities. Make sure you set all mono and stereo channels the same. Before you make your choice, consider whether you want to use AUX5 or 5/6 for the internal effects (should be post) and/or AUX6 to feed aux fed subs (also post). [. . . ]
