[. . . ] Clean feed outputs are provided on XLRs on an 8 group console and jacks on a 4 group console. Signal is sent to Aux 1-4 buses via the four level controls. The Auxs have unity gain when the controls are fully clockwise. The source signal is fed from pre or post group faders. The pre or post switch operates on all four Auxs. The other four Auxiliaries are fed from the other group (Right) fader. Each Dual Group module contains one clean-feed master therefore the amount of clean-feed buses is dependent on the amount of Dual Group modules fitted. The Level control adjusts the level of the balanced Clean-Feed output which is fed from the selected clean-feed input module. Jumpers make the clean-feed bus selection of which positions are used to source on the 14 position motherboard. Therefore if the signal is inserted into the first of the input modules (clean-feed 1) it will then be removed from the clean-feed output 1 on the group module. The Talk Enable switch provides signal from the Comms system to be fed to the clean-feed outputs when the Comms system is activated. The clean-feed Mute switch cuts off the signal to the clean-feed outputs. The clean-feed AFL switch provides the post level signal to the monitor speakers replacing the selected source. 2. 3. 4. 6. 7. Signal is sent to the Aux 1 & 2 bus via the Aux Level control (optionally Aux 3 & 4 using the internal jumpers). All the Auxs have unity gain when the controls are fully clockwise and are switched pre or post in pairs by the PRE switches. The source is fed from the Group Return. The Stereo Return Level control adjusts the level of the return signal. Gain of +10dB of gain is provided when the control is fully clockwise. The ST/Mix Group switch determines whether the output can be sent to the Stereo Bus or the associated pair of groups. 8. The Pan control feeds the signal to the Stereo mix or the groups. The Return Mute switch cuts of the signal from the Stereo bus or the group bus. Also mutes the PFL and aux pre and post. [. . . ] Using the Q switch selects either 0. 7 or 1. 3 Q Factor. The HP switch inserts a HI-PASS filter into the signal path. The -3dB point is fixed at 80Hz at 18dB per octave.
