While sending signal from your
program source, slowly turn the
PROGRAM INPUT level control
clockwise until the CLIP LED
flashes. Then back it off until
the CLIP LED does not flash, or
only flashes occasionally on
peaks in the program source.
2
While sending signal from your
cue source, slowly turn the CUE
INPUT level control clockwise
until the CLIP LED flashes. Then
back it off until the CLIP LED
does not flash, or only flashes
occasionally on peaks in the cue
source.

While sending signal from your
program and/or cue source,
slowly turn the Channel 1 level
control clockwise until the green
SIGNAL LED lights. You should
be able to hear program and/or
cue signal in your first set of
headphones now.

Adjust the Channel 1 level
control for the desired listening
level.

If you are using program and
cue signals, adjust the PRO-
GRAM INPUT and CUE INPUT
level controls to achieve the
desired balance of program to
cue signal.

Repeat steps for any additional
headphone sets, using channels
2–6 of the 506E. See in this
section, Calculating the Maxi-
mum Amplifier Load, to find out
how many headphones of
various impedances may be
used with each output of the
506E.
