Audio/Intercom Routing - THOMSON LDK 20 S Operator's Manual

Audio/Intercom Routing

Audio path
The right panel of the camera has two connectors for
audio microphones. The signals applied to these
connectors are amplified and passed to the multiplexer/
transmitter section of the camera which sends them
to the base station via the Triax cable. The amplification
factor of the audio microphone signals can be selected
via the control system. When the camera is used in
the Local mode these connectors are not used as the
audio microphones are connected directly to the
recorder.
Phantom power is available for the audio microphones.
The default value is +48V (refer to the installation
manual for information on changing this value).
Intercom
Two intercom headsets can be connected to the
camera; one for the cameraman and one for the
floorman. An additional intercom signal is available
for the tracker.
In the triax mode there are three intercom channels
from the base station to the camera. These carry the
engineering intercom signal, the production intercom
signal and the programme intercom signal. Two

intercom channels from the camera to the base station
carry the floorman and cameraman intercom
microphone signals. The latter can be routed in the
base station either to engineering or to production via
the intercom routing switch on the camera.
The tracker headphones receives the cameraman
microphone signal, the production intercom signal,
the programme audio signal and either by default the
floorman microphone sidetone signal or the
engineering intercom signal.
The engineering intercom signal, the production
intercom signal and the programme intercom signal
from the base station are all available for the
cameraman headset. The volume of these signals
can be adjusted and can be switched to either the right
or left side of the headset. The floorman microphone
can also be switched to the left side. The cameraman
microphone sidetone signal is always present on the
left side. The volume of this signal can also be
adjusted.
In the local mode the audio monitoring signal from the
VTR is substituted for the programme audio signal
from the base station.
