Using Talkback
The two female 5-pin XLR connectors allow you to plug in two headsets, so that you and
another crew member can have communication with the rest of the crew simultaneously.
The intercom controls for each headset are grouped into two sets for two independent
intercoms, and are effectively three way audio mixers for each headset XLR connector that is
directly below.
The intercom controls for each headset are located
directly above each headset connection
You will hear the audio from the feeds that you have selected for ‘ret 1’ and ‘ret 2’ through a
connected headset. The ‘pgm 1’ and ‘pgm 2’ dials adjust the audio levels of those feeds, and
the ‘incom’ dial adjusts the overall volume. The ‘mic’ switch allows the operator to turn their
headset microphone ‘on’ or ‘off’.
Each intercom also has 2 selectable channels, a production channel and an engineering
channel. This means that for broadcast setups with a large crew, you can split your crew
communications between the two channels. The production channel uses audio channels
15 and 16 of the SDI stream, and could be setup to allow you to communicate with the director,
producer and other crew members in the control room or broadcast truck. The engineering
channel uses audio channels 13 and 14 of the SDI stream, and could be setup to allow you to
communicate with the lighting crew, technical operators and other camera operators. The
engineering channel will be enabled in a future software update.
The Blackmagic Camera Fiber Converter also includes a standard 10 pin connection for tracker
talkback, which is perfect when both headset connections are in use and you need to feed an
additional talkback connection for your crane operator.
There is also a backup channel available for use while setting up or troubleshooting the camera
chain in case the fiber link is down.
