The SSL SDI-MADI interface is a 1U rack mounted chassis including two mains power supplies thus providing ‘On-Air’
redundancy.
The unit provides the interface between SDI video bitstreams and digital audio. SDI-MADI extracts up to 16 audio channels
from each of the unit’s four SDI inputs to provide a total of up to 64 audio channels in both MADI (AES10id-2008) and
AES3 (AES3-1992) formats.
SDI inputs independently auto-sense between 3G, HD and SD standards and provide loop-through outputs for
downstream equipment. With a comprehensive range of synchronising options and switchable sample rate convertors, the
SDI-MADI is designed to reliably and seamlessly integrate into any broadcast environment where SDI-embedded audio
channels require format conversion.
More detailed installation and operational information can be obtained from the separate installation manual which can be
downloaded from the SSL website:

Connection to the Blackrock computer is by single unidirectional fibre (a return path from the Blackrock is not required).
Note that the fibre connector on the SDI–MADI unit is the ST version.
If a redundant connection to the Blackrock is required this can be implemented by utilising the BNC copper-MADI
connector on the rear panel. This signal is a duplicate of the primary MADI but will need to be converted to fibre media –
this can be achieved by using the SSL copper-to-fibre media converter ‘59/4'=’. The diagram opposite shows the
redundant connection.
