Cabling Up the AirSpeed Multi Stream
57
To connect video reference cables:
1. Ensure that you have the proper SDI video (75 ohm-rated) interface coaxial cables
available.
2. Connect a composite video reference source (house reference, blackburst, or tri-level) to
one of the reference input connectors (labelled REF IN/THRU).
If the AirSpeed Multi Stream is the last device in your reference loop, terminate the
remaining Ref Loopthrough connector with a 75 ohm-rated terminator. If the AirSpeed
Multi Stream is in the middle of your reference loop, connect the remaining REF
IN/THRU connector to the next device’s reference input.
3. Connect the other end of the video reference cable to your devices that are sending the
input signal to the AirSpeed Multi Stream.
Connecting SDI Video Input Cables (for SD Models)
The SDI Video Input connections are marked on the rear of the AirSpeed Multi Stream SD.
The following procedure describes which connector to use. To find the exact location, see
“Video/LTC Connections (SD Model)” on page 40 .

When an AirSpeed Multi Stream channel is in Record mode, the signal present at the video
input will display on the corresponding video output.
The following illustration shows the location of the SDI IN video connectors on the rear of
the AirSpeed Multi Stream SD chassis.
To connect SDI video input cables on the SD chassis:
1. Ensure that you have the proper SDI video (75 ohm-rated) interface coaxial cables
available.
2. Connect the SDI input signal to an incoming SDI input (one of the two labelled IN 1-2)
for AirSpeed Multi Stream SD models.
3. Connect the other end of all SDI input cables to your devices that are sending the input
signal to the AirSpeed Multi Stream SD.
