PFL Button (Pm-Fader Llsten)

Engaging the PFL allows you to listen to the Pre-Fader signal in the monitor

and headphone outputs. The PFL system takes its signal after the EQ section but
before the channel fader. This allows you to make signal level and quality checks
before bringing up the channel in the mix. When a PFL switch is engaged, the L/R
meters will indicate the PFL level; the channel PEAK Indicator will illuminate at half
intensity; and the PFL indicator in the master section will illuminate.

Peak signal Indicator

This red LED illuminates when channel audio signals approach overload. The

peak detection circuit samples the signal after the preamp, after the equaliser and
after the fader so revealing risk of overload at all stages.

Signal present Indicator

intensity will vary with the strength of the channel signal starting at

and

reaching a constant intensity when the signal reaches approx

The EQ, fader

and mute settings will not affect the LED.

position is at the 0 mark. However, an extra

boost can be obtained with the

fader fully up. Also provides the signal feed to AUX mixes selected for POST

FADER operation.
