User manual SOUNDCRAFT GP1

[. . . ] Although the GP1 is primarily designed for remote use with on-board battery power, the mixer may also be rack mounted (8 Input variant only), or furniture mounted. It may be mains powered via the PPS110 power supply. 2 Introduction Precautions and Safety Instructions General Precautions Avoid subjecting the mixer to conditions of excessive heat or cold, or installing it in positions where it is likely to be subject to vibration, dust or moisture. Do not use any liquids to clean the fascia of the unit: a soft dry brush is ideal. Avoid using the mixer close to strong sources of electromagnetic radiation (e. g. [. . . ] 6 The High-Pass Filter switch, when depressed, puts a High Pass filter into the Signal path. The filters 3dB point is at 80Hz, and the filter has a slope of 12dB/octave. EQ The EQ has two shelving filters. C 5 BAL R L MUTE 14 12 PFL 10 5 13 PK 0 7 The two shelving filters are in-circuit when the EQ button is depressed. 8 The shelving HF control provides a maximum cut/boost of 10dB at 10kHz. Auxiliary Sends 15 5 10 20 30 40 50 60 10 The AUX1 Level control is used to control the signal level which is sent to the Auxiliary 1 output mix. The signal, which is a mono mix of L & R, can be varied between 0dB and infinite attenuation. Aux1 may be selected, via the Master Module, as pre-fade or post-fade. 11 The AUX2 Level control is used to control the signal level which is sent to the Auxiliary 2 output mix. The signal, which is a mono mix of L & R, can be varied between 0dB and infinite attenuation. Aux2 is always post-fade. Note: the mono mix is at a level equal to (L + R) -6dB. 18 8 Std Stereo Line Input PFL 12 The PFL switch routes the pre-fade post-EQ signals, as a mono mix, onto the PFL mix bus. The PFL control bus is also activated. The associated PFL LED is illuminated when the PFL switch is active. Peak 13 The PEAK LED starts to illuminate when there is 8dB of headroom left. Output 14 The MUTE switch routes the outputs from the Fader onto the Left and Right Main Mix buses; it also routes the other post-fade paths, i. e. Aux1 and Aux2. The associated MUTE LED is illuminated when the Mute switch is active. 15 The 100mm Fader provides 10dB of gain at maximum, and infinite attenuation when closed. Two female XLR connectors are provided at the rear of the Stereo Line Input Module. The connections are as follows: Pin 1 Pin 2 Pin 3 Ground (Screen) Hot (In Phase) Cold (Out of Phase) Std Stereo Line Input 19 20 Std Stereo Line Input Basic Stereo Line Input Basic Stereo Line Input 21 Basic Stereo Line Input Module Input 1 The LINE/DIN switch allows you to select a nominal level of +4dBu (when the switch is released) or a nominal level of 10dBV (when the switch is depressed). 2 The rotary GAIN control provides 0dB at the centre detent, and a cut/boost of 15dB at the extremes of its travel. 3 The centre-detented BALance control provides a +3db boost to one channel and a 8dB cut to the other channel at each end of its travel. 0 L NE I DIN 1 0 GAIN + 2 4 HF + EQ The EQ has two shelving filters. 0 5 LF + 4 The shelving HF control provides a maximum cut/boost of 10dB at 10kHz. Auxiliary Sends 6 The AUX1 Level control is used to control the signal level which is sent to the Auxiliary 1 output mix. The signal, which is a mono mix of L & R, can be varied between 0dB and infinite attenuation. Aux1 may be selected, via the Master Module, as pre-fade or post-fade. 7 The AUX2 Level control is used to control the signal level which is sent to the Auxiliary 2 output mix. The signal, which is a mono mix of L & R, can be varied between 0dB and infinite attenuation. [. . . ] There is also a 6-pin female connector (COMMS) to provide talkback facilities. The connections are as follows: pin 1 pin 2 pin 3 pin 4 pin 5 pin 6 Not Used Chassis Gnd System Gnd Balanced Talkback Output Balanced Talkback Output -+ Not Used The TALKBACK OUTPUT signal is normally a mono mix of whatever is selected for Headphones 3. There is, finally, a screw-post connectors for CHASSIS GROUND.
