Level

This control adjusts the level of the channel signal to the left & right PGM bus,

ALT bus and post fade Aux.

With the pot fully clockwise, the channel has unity gain.

ON Switch

This mechanically latching switch operates the channel mute circuitry, turning the

signal to the PGM, ALT and Aux buses on or off.

With the button depressed the signal is routed to the PGM bus and the pre/post

AUX bus. With the button up the signal is routed to the ALT bus and the prefade

AUX bus.

The switch is illuminated green when pressed.

There is also a remote mute option wired to a D type connector on the rear panel.

When this is wired and operated the green ON LED is switched off, and the mute

circuit is activated, regardless of whether the ON switch is pressed. Also the ON

switch activates a logic output that can be used to control an 'ON AIR' light or simi-

lar.

PFL Switch

The PFL (Pre-Fade Listen) switch sends the channel signal to the PFL bus and subse-

quently to the headphones/CRM speakers and the main L R meters. Used for

checking the audio signal before raising the level or un-muting the channel.

SIGNAL & PEAK LEDs

The Signal LED illuminates when the pre-fader signal level is above –15dB.

The Peak LED illuminates and stays on for around 0.5 seconds when a peak level is

detected (pre-fader signal) within 5dB of clipping.
