EXTERNAL CONNECTIONS
Ensure TX key is set to ‘off’ while connecting up signal sources.
Connect composite video PAL/NTSC source to connector labelled ‘CVBS’
(Options) Connect serial digital PAL/NTSC SD / HD source to connector labelled ‘(HD)SDI’.
Connect analogue (or digital option) audio to the rear panel 15 way ‘D’ male connector.
An interface cable (spares part number A41-207359) that adapts this to 4-x XLR female
connector is supplied with the exciter.
With AES /EBU option, the “right channel” XLR becomes the digital input.
If an external ASI stream is to be multiplexed in with the local encoder in the exciter, connect
the external source to BNC labelled ‘ASI IN’.
Caution should be observed as 17V DC may be present on the L-Band output connector.
