For
DC
remote
control,
the audio is always routed through the
non-ALC
path.
When
the
TTRC
Audio
board is jumpered for
a
four-wire system,
the
transmit
wireline interface is across
Line
1
(+)
and
Line
1
(-) on the
Junction
Box screw
terminal strip. The receive wireline interface is across Line2 (+) and
Line?
(-).
When
the
TTRC
Audio
board is jumpered for
a
two-wire system,
the
transmit /
receive wireline interface is across
Line
2
(+) and Line
2
(-) on the
Junction
Box
screw terminal strip.
For two and four-wire systems, these connections
are 600
Q balanced inputs,
unless otherwise jumpered for
900
Q balanced inputs.
NOTE
If the station is
a trunked station without
the
Console
Priority
Option (C115) or is configured for
DC
remote
control,
proceed to the
DC
Remote
Control/Trunking
Adjustment.
If
this is
a trunked station
with
the
Console
Priority
Option (C115), proceed to the
Trunking/Console
Priority Adjustment.
