[. . . ] 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. 9 The LF control provides a maximum boost/cut of 10dB at 100Hz. 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. Options Rear Connector Optional input transformers can be fitted. 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. 6 5 The LF control provides a maximum boost/cut of 10dB at 100Hz. 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. [. . . ] L-R selects the main mix. AUX2 L-R H/P 2 2 3 2 The H/P 2 level control adjusts the level of the Headphones 2 signal. Warning!Damage to your hearing may result from setting this control too high. 0 10 TALK 3 The TALK button, when depressed, routes the currently-selected source, as a 4 5 mono mix, to the left headphone, and the signal from the inbuilt microphone to the right headphone. MONO EXT EXT 4 The MONO EXT switch sums the External Monitor input to a mono signal. Headphones 3 5 A bank of four interlocking switches selects the input source fed to the stereo Headphone 3 .
