Pushbuttons
When the ON button is pressed, the phone line is seized and the
system sends a burst of white noise down the line, allowing the
hybrid to adapt to the phone line prior to the
start
of conversation.
During this time, the outputs
are
muted.
At the conclusion of the period, the output
is
and the conversation may proceed.
When the OFF button
is
pressed, the phone line
is
released.
The AUTO button is a momentary button that, when a "Super"
Auto-answer board
is
installed, toggles the unit
in
and out of the
auto mode. Its accompanying LED indicator
illuminates when in auto mode. (If the "Super" Auto-answer board
is
not installed, this button and LED
is
brought to the rear panel
remote connector and may be used for any desired external
function.)
Output Processing: Override
This pushbutton engages two independent functions: the culler
ducking and the ducking function. In most broadcast
applications, you will find that engaging the override function
results in better overall performance.
Caller
Ducking
This function operates in the caller audio path. When active,
there is approximately 6 dB of ducking applied to the caller audio
when the announcer speaks. However, very little change in caller
level will be noticed due to the very high speed operation
of
the
duck function and the provided by the presence of the send
audio.
