3.2.3 Selecting monitoring signals
Viewfinder display signal
The viewfinder can display local (from camera) or external (from base station) video. Two
switches at the back of the adapter determine the signal that is displayed in the viewfinder.
The viewfinder display switch determines how the local and external signals are displayed in
the viewfinder:
– Loc: displays the local signal (Y only) in the viewfinder,
– Mix: displays a mix (-½A + ½B) of the local (Y only) and external signal or
– Ext: displays the external signal in the viewfinder
When the viewfinder display switch is set to Mix or Ext, the external signal selection switch
determines which external (return) video signal from the base station is displayed in the
viewfinder:
– Ext1: displays external signal Ext1 or
– Ext2: displays external signal Ext2 or Ext3.
Go to the INSTALL > BUTTONS > EXT2 ASSIGN menu and select Ext3 to use the Ext3 channel
instead of Ext2.
3.2.4 Using audio
Analog audio channels
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.
The channel 1 input socket selection switch selects either:
• the socket at the front-right of the camera, or
• the Mic 1 audio channel 1 connector at the rear of the adapter
as the input for channel 1.
The rear input level switch selects either a line level input or a microphone level input for the
channel 1 rear connector. The line level input sensitivity is 32 dB lower than the microphone
input sensitivity.
