Each of the twelve mixes has its own 60mm master fader.This fader controls the main output of the mix and allows the operator to easily adjust the level sent to the perform- ers. Up to 10dB additional gain is available.The faders are arranged in odd/even pairs for ease of use when operating in Stereo mode. Nominal setting is at the 0 (unity) point.

Peak/Signal LED + AFL Switch & indicator

L E D PK/SIG This bi-color LED indicates the pre-fader mix level with varying intensity Green illumination. If critical internal signals get to within 3dB of clipping, the LED will turn Red.This LED will also indicate AFL activation by turning Red.

AFL This switch allows the engineer to monitor the post-fader level of the mix. Pressing the switch will turn the PK/SIG LED Red and feed the mix to the Solo system where it can be viewed (Solo meters) and monitored (HP and Monitor Out) by the operator. In Mono mode, only the associated mix is fed to the Solo system. It appears as a mono signal in the Solo system (equal level in both left & right). If the associated STR PAIR switch is depressed (located above the odd-numbered faders), then pressing EITHER the odd or even AFL switch will cause BOTH LEDs to illuminate and both mixes will be fed to the Solo system as a stereo pair, odd mix to left, even mix to right.

Repeat as necessary:

The previous descriptions of the functions associated with each of the Master faders are repeated for the remaining Master faders.The stereo pairing, when activated by a STR PAIR switch, always operates between the associated mixes 1-2, 3-4, 5-6, 7-8, 9-10 and 11-

12.Not only are the output faders and their controls affected by this switch, the associat- ed mix sends on all the input channels are also affected.The Sends are reconfigured from their normal Lev/Lev operation (odd-pots feed odd buses, even-pots feed even buses) to the Lev/Pan stereo configuration (odd-pots feed BOTH odd and even buses, even-pots pan between the buses).
