The compression slope trim pot is used to compress the paging audio input signal. This
feature will prevent an input signal that is too high from being broadcast at that level. While
each room has its own paging volume level to prevent speaker overdrive, the compression
slope adjustment is used to prevent the input signal from being distorted.
The input level adjustment trim pot is used to determine the level of the audio input signal.
With this adjustment, low level signals can be raised or signals that are too hot can be low-
ered.
The trigger level trim pot is used to adjust the sensitivity of the audio input trigger. There are
a total of eight paging triggers. Six of these are serially controlled, one is a voltage trigger,
and one trigger is audio sensing. This trim pot is used to set this trigger such that it engages
and disengages appropriately.
P-16 Module Front Panel Setup
The P-16 Preamplifier module features twenty-two LEDs which indicate data transmission
and reception, the presence of voltage (power), which zones are active (1-16), and whether
the system is on. The
diagram below details
these LEDs and also
shows the position of
the address selector.
The address selector
sets the address of
the P-16 module
since as many as six
P-16s can be used for
up to 96 zones. Ad-
dress “0” is the default address for zones 1-16 operating at a baud rate of 19200.
V-16 Module Front Panel Setup
The V-16 Video Switching module features twenty-two LEDs which indicate data transmis-
sion and reception, the presence of voltage (power), which outputs are active (1-16), and
whether the system is
on. The diagram below
details these LEDs and
also shows the position
of the address selector.
The address selector
sets the address of the
V-16 module since as
many as six V-16s can
be used for up to 96
zones. Address “0” is
the default address for zones 1-16 operating at a baud rate of 19200.
