The PFL (Pre-Fade Listen) switch allows you to listen, via the Monitors
section, to an the input on this channel. When the Fader is moved away from the
down position the PFL circuit is automatically deactivated: PFL cannot therefore
be activated when the Fader is up. A red LED glows to indicate that the PFL circuit
is active. If the REM switch’s LED is glowing at half brightness and the PFL is
pushed, the START relay will operate.

The smooth-action, 100mm FADER gives a gain of unity (0dB) when it is in
the fully up position. The scale alongside the Fader indicates the attenuation, in dB,
for any position. There is a microswitch attached to the Fader which detects when
it is in the fully down position. This microswitch helps to control many of the
features which are described in this section.
The input to the channel will be on-air whenever the Fader is open (unless the cough
switch is closed).
Note: Each Mono Input channel can be configured as a Local or Distant channel.
This controls which monitor circuit will be muted when the channel’s Fader is
opened and the mic is selected.
