3.3 Audio
A high quality audio channel is available. Set the gain levels (-22 dB to -64 dB) for this
channel in the Audio section of the Install menu. A high-pass filter for the channel can also
be switched on via this menu.
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). The front microphone socket always has a
phantom power supply (+48V).
3.4 Intercom
The production (PROD) intercom channel is sent from the Base Station to the camera
operator's headset. The camera operator's intercom microphone signal is sent to the
Base Station.
The Intercom section of the Install menu contains various settings for 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 can be 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
production (Prod) or turns off the intercom. The third (momentary) position also routes the
intercom signal to production but operates only as long as it is held in place.
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.
Intercom headset volume control
This control adjusts the volume of the production signal to the camera operator's headset
when selection switch (2) is in the REAR position.
