4.12.3 Using audio
Two high quality audio channels are available in the triax mode. Set the gain levels (-
22 to -64 dB) for these channels in the Audio section of the Install menu. A high-
pass filter for each channel can also be switched on via this menu.
Audio channel 1
The microphone for channel 1 is connected either to the socket at the front-right of
the camera or to the Mic 1 socket on the triax adapter. A 3-position switch (5)
activates the socket at the front-right or the connector at the rear. The third position
selects the rear socket with a phantom power supply (48V).
Audio channel 2
The microphone for the second audio channel is connected to the Mic 2 socket on
the triax adapter. A 2-position switch (8) selects a phantom power supply (48V) for
the second audio microphone.
4.12.4 Intercom
Three intercom channels – production (Prod), program 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. A tracker
can also connect a headset to the intercom system to receive all of the channels
from the Base Station and the camera operator's microphone signal as well. The
tracker's microphone signal is passed to the camera operator and to the Base
Station.
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.
Additional controls are found on the back of the adapter.
Intercom microphone routing switch
This 3-position switch (1) routes the camera operator's intercom microphone signal
to engineering (Eng) or production (Prod), or turns off the intercom. Use the VTR
Start button at the front of the camera, or the VTR button on the lens, to send the
camera operator's intercom microphone signal to production, regardless of the
position of this switch.
Production volume control selection
Use this 2-position switch (2) 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.
