CAUTION! When phantom power is switched on, make sure that any channel you are plugging a mic into is muted and all monitors and auxs are at minimum. Otherwise there will be a loud
pop in the PA. This is normal. It is best to plug all mics into their respective channels with the phantom power switched off. This reduces noise in the PA and reduces the chances of the mic being damaged.
16.LOW CUT: A low cut filter with an adjustable corner frequency (10 to 300 Hz). It is used to filter out rumble, wind noise, breath thumps, stage noise, and other low frequency components that rob power from the amplifiers and muddy the signal. To disable the filter, set it at the minimum frequency setting.
17.LED METER ARRAY: A
18.AFL: Connects the channel’s output signal (post fader) to the AFL mix. This mix is the default headphone and wedge mix. Its LED will light when this switch is pressed to identify which signals are included in the AFL mix. At least one source should be assigned, or there will be no headphone or wedge signal unless the PFL is active.
19.MONITOR MUTE: Mutes the monitor output. Its LED will light when muted.
20.MASTER FADER: Sets the overall level of the signal that is sent to the output jacks. The opti- mum setting for this control is the “0” (unity gain) position.
21.TALKBACK LEVEL: Sets the level of the talkback mic that is sent to monitors
22.TALKBACK MIC INPUT:
23.TALKBACK ASSIGN: The talkback signal is always sent to monitors
24.TALKBACK ENABLE: Engages the talkback mic while held down. The signal is routed through the talkback assign (#23) switch and controlled by the talkback level (#21).
25.PFL LEVEL: This control sets the level of the PFL mix that is sent to the headphones and the wedge outputs when the PFL is active. In normal operation, this control is adjusted to set the PFL level to match the AFL level.
26.HEADPHONE OUTPUT: This stereo jack TRS provides drive for the headphones. The level is set by the headphone level control. Tip=Left, Ring=Right, Shield=Ground.
27.HEADPHONE and WEDGE LEVELS: Independent adjustments of the headphone and wedge outputs. The source changes from the AFL mix to the PFL mix whenever the PFL is active. If no output is assigned to the AFL mix, there will be no signal present until a channel is assigned to the PFL mix. The wedge level will diminish
28.PFL ACTIVE: This LED flashes when the PFL is active and its signal is overriding the standard AFL mix in the headphone and wedge outputs and at the right meter. The signals that are present in the PFL mix can be seen by the individual PFL LEDs.
