2.6 AUDIO MIXER
The Cam racer basestation audio section provides a small mixer that enables to send to each internal audio
channel transmitted to the camera (Intercom1, Intercom2, Audio1, Audio2) a mix of the 6 physical input
sources (Intercom1, Intercom2, Pgm1, Pgm2, Audio1, Audio2).
Depending on the application, any user can hear the desired audio mix in his headset or earpiece.
This useful feature also avoids any complex cabling between an external audio mixer and the cam racer
basestations.
This setting is done within the “volume settings” section of the settings web page. A small mixer subset is
available for each audio going to the camera
To add a source to the mix, firstly tick the “reinject” box and secondly adjust the desired level.
For multiple setting, use the Download / Import configuration at the bottom of the settings pages to Save /
Recover settings from your computer.
2.7 INTERCOM BEHAVIOUR
Intercom have 2 operation modes:
•
Single headset with 2 channels (Most common).
•
Separate headset with 1 channel on each headset.
The selection is done with the combo box named “Intercom mode”
The Talk / Talk latch action can be done directly on the camera unit or trough ground closures located at
SERIAL 1 RJ45 or on the Hirose12 Multipin depending of the mode choosen.
Talk latch is enabled by pressing momentaneously (> 0.5 second) the talk button on the desired channel.
After this delay the unit will turn to simple Push to Talk and will close the channel upon button release.
2.7.1 2 CHANNELS INTERCOM
Talk command sources are:
•
Camera unit button (enable talk on channel1 and/or chennel2),
•
Serial 1 RJ45 ground closure (enable talk on channel1),
•
Ground closure on the Hirose 12 connector (enable talk on channel1).
By default or when talking on channel 1, the blue button rotation will adjust global listening level of the audio
mix programmed on channel 1. When talking on channel 2 rotating the blue button will adjust the channel 2
listening level without affecting the other levels heard in the headset.
