Transmitter Wireline Audio Adjustment
This procedure adjusts the transmitter wireline audio level. When performing this
procedure for Tone Remote Control, there
are
two different paths
the transmit
audio can take
via Line
1
(ALC
path)
or
Line
3 (non-ALC
path). For conventional
stations, the default is
Line
1.
For trunked stations, the
default is Line
3.
The only
path
the
audio can take
via Line
3 is the
non-ALC
path. Refer to
Figure
4-20 for
a
block diagram
of the
ALC
circuitry.

For adjusting transmit audio via
the
ALC
path,
the
standard
HLGT/FT/LLGT
sequence should be followed for
the
ALC
circuitry
to
adjust accordingly.
For adjusting transmit audio via
the
non-ALC
path,
a
1
kHz
tone
should
be used.
There is also
a
course
level adjustment via EEPOT E which
compensates for
a
higher
or
lower levels of audio. There
are
four different settings for this
EEPOT.
EEPOT
I
should only be used
if
the
level for
EEPOT
7
could not be met for audio
through
the
non-ALC
path.
For
Console
Priority
Option (C115), the console is connected
to
Line
1
or
Line
2
depending
on the
wireline setting. The
trunking
phone interconnect audio is
connected to
Line
3
and
Line
4.
The value of
EEPOT
7
has two values, one for
interconnect audio and one for console audio.
EEPOT
7
must
be
aligned twice in
this configuration.
