[. . . ] The signal is accessible via separate 1/4" jacks on the rear connector panel. The factory default is post-EQ. 7 8 9 10 11 12 17 Output 13 The electronically latching PFL switch feeds the pre-fade, pre-mute signal to the PFL bus, which in turn feeds the engineer's wedge speakers and phones outputs via the Master section. 14 The signal in the module is turned on and off by the CUT switch and by the mute buses (see next paragraph). An integral red LED in the CUT switch indicates when the signal is cut. 18 15 Each Input module is assigned to the four mute buses via the M1 - M4 buttons. Each switch has an integral red LED, which indicates when the module is assigned to its respective mute bus. When the module is muted by any of the mute buses, the LED in the CUT switch illuminates. 16 The Post-fader signal level is controlled by a 60mm Fader. The post-fader signal is routed to the Direct Out jack on the rear connector panel: this is a ground compensated output at a nominal level of -2dBu. The post-fader signal is also fed to the Groups and the Stereo Mix buses (see below). Groups 17 The input signal is sent to the group 1 - 16 buses via individual Level Controls. These have unity gain when fully clockwise, and are activated using the associated ON switches. Each switch has an integral green LED. 19 18 The group sends are switched pre- or post-fader by the PRE buttons. The pre-fade signal may be sourced from one of the following three options: · · post-mute and pre-fade pre-mute pre-EQ and pre-insert. 20 14 16 15 · The source selection is done in two blocks of eight sends, using push-on jumpers. The factory default is post-mute and pre-fade. 13 18 Input Module Stereo Mix 19 The post-fader signal is sent to the stereo mix bus via the L/R (level) and PAN controls. The mix bus send is activated by the ON switch, which has an integral green LED, and may be set pre- or post-fade by the PRE switch. The pre-fade signal may be sourced from one of the following three options: · · · post-mute and pre-fade pre-mute pre-EQ and pre-insert The source selection is done using push-on jumpers. The output module contains two group output sections, stacked one above the other. The EXT IN control adjusts the level of the external signals, with 10dB of gain fully clockwise. 12 The MNO (mono) switch sums the external signal to mono before it is fed to the stereo mix. 13 The latching ON switch activates the external input. 14 The LSTN (listen) provides a mono pre-fade, pre-ON solo to the 'phones or wedge output. LISTEN is not affected by the AUTO CANCEL or SOLO CLEAR functions, and overrides any output AFLs if INPUT PRIORITY is active. Using the Solo System A solo system of pre-fade listen (inputs) and post-fade listen (outputs) feeds the operator's wedge/'phones outputs. Normally, all active AFL, PFL and LISTEN signals are summed together and fed to the wedge or phones outputs. When INPUT PRIORITY is selected by the ENBL switch, which has an integral red LED, an active PFL or LISTEN will replace any AFL signals, which will be audible only when all the PFL/LISTENs are released. 15 The PFL TRIM control gives +/-10dB of level trim for PFL/LISTEN signals. The SOLO CLEAR button lights when any AFL, PFL or LISTEN is active. When AUTO CANCEL is activated by the ENBL button, which has an integral red LED, any AFL or PFL will cancel any currently active solo, so only one AFL or PFL can be active at once. LISTEN buttons are not affected. Master Module 31 RS5512 LAMP 31 OSCILLATOR ON External Solo Signals The PFL, AFL Left and AFL Right external inputs, from XLRs on the lower rearcon, allow signals from another console to be added to the PFL and AFL buses. When no solos are active on the console, both PFL and AFL left and right external signals are monitored by the 'phones and wedge. When INPUT PRIORITY is not active, the external signals are mixed with any current internal PFL, AFL or LISTEN signals; if INPUT PRIORITY is enabled and a PFL/LISTEN is active then the external AFL input is cut. Internal jumpers allow the signal fed to the 'phones/wedge when no solos are active to be changed from the external PFL/AFL signals (as described above) to the stereo mix postfade signal. [. . . ] F Gain tolerance is +/- 1. 5dB or 10% of the indicated value, whichever is the greater. G Group Noise: noise measured at the group output with faders at unity, and channel send pots down.
