Configuring Channel Cards
Low Level Guard Tone Amplitude
The Low Level Guard Tone Amplitude (LLGT) for tone channels defaults to -30 dB but is
a software configuration item for the Universal Tone/Local DCC (P/N 950-9819 and 950-
9820). The LLGT can be changed from -20 to -34 dB in 2 dB increments as described in
the Universal Tone/Local DCC Software section.
LOTL Disable
When parallel control points are used, the FCC requires that the LOTL function be
enabled. If no parallel control points are installed, disable the LOTL function because,
when enabled, the LOTL function operates even when this console is transmitting.
For Tone/Local Cards (950-9820) using tone control, LOTL enable/disable is configured
in software. Refer to
on page 56 for information about the
tone-Custom
parameters
used to enable and disable tone LOTL.
Channel VOX Hang Time
VOX hang time refers to the few seconds of call indication after voice activity has
stopped. Normal VOX hang time on each channel is about two seconds, which may be too
long for radio channel to radio channel or radio channel to telephone patching. VOX hang
time is a software configuration item and can be modified as described in
Dual Channel Recorder Output Audio
Each channel has a recorder output on which the receive audio is always present. The
transmit audio may or may not be present depending on the jumper settings, as shown in
