5.8.4 Intercom
Three intercom channels – production (Prod), programme sound (Prog) and engineering (Eng) –
are sent from the Base Station to the camera operator's headset. The camera operator's
intercom microphone signal is sent to the Base Station. Routing and volume controls for the
intercom are on the back of the adapter.
Figure 5-12. Intercom controls
Production intercom volume control selection
Use this 2-position switch to control the volume of the production signal in the intercom either
at the front of the camera or at the rear of the adapter.
Intercom microphone routing switch
This 3-position switch routes the camera operator's intercom microphone signal to engineering
(Eng) or production (Prod), or turns it off. The VTR Start button at the front of the camera, or the
VTR button on the lens, can be assigned to send this intercom signal to production, regardless
of the position of this switch.
Intercom headset volume controls
• Prod - adjusts the volume of the production signal to the camera headset when selection
switch is in the REAR position.
• Prog - adjusts the volume of the programme signal to the camera headset.
• Eng - adjusts the volume of the engineering intercom signal to the camera headset.
The INTERCOM section of the INSTALL menu contains various settings for all these channels.
Signals for left and right headset muffs and sidetone levels can be selected. Intercom
microphone amplification levels, phantom power supply and microphone on/off switches are
also available in this menu.
Tracker intercom
A tracker can connect a headset to the side of the adapter to receive the intercom channels
from the Base Station and the camera operator's microphone signal. The tracker's microphone
signal is passed to the camera operator and to the Base Station.
