Main Meters
The main Left & Right meters will show the signal level
at the main LR mix outputs or the main M mix output
depending on the selector switch below the Phones
Level control. If any PFL or AFL switch is pressed the
meters will show that signal level. Basically, the meters
show the headphones monitor signal pre the head-
phones level control.
The PFL/AFL active LED illuminates if any PFL or AFL
switch is pressed.
Note that PFL and AFL monitoring will be in mono.

Talkback
A microphone xlr connector is provided with phantom
power applied as a factory default.
The TB Level control varies the gain of the talkback
amplifier from 20dB (MIN) to 55dB (MAX).
The two switches send the talkback signal to Auxes 1
to 4 and to the main L, R & M mixes. When not using
talkback, it is best to leave these switches in their out
position.
