Occupying 1U of rack space, Sam64 provides the interface between SDI bitstreams up to 3G (2.9Gbps – 1080p60) and AES3 plus Madi digital audio
The recent BVE exhibition at London’s Earls Court saw the launch of 4HM Limited, a new company developing high-quality products to meet the demands of broadcast facilities and systems integrators, and its Sam64 SDI audio interface.
Occupying 1U of rack space, Sam64 provides the interface between SDI bitstreams up to 3G (2.9Gbps – 1080p60) and AES3 plus Madi digital audio. Sam64 de-embeds 16 audio channels from each of the unit’s four SDI inputs to provide a total of 64 audio channels in both Madi and AES3 formats. All SDI inputs independently auto-sense between 3G, HD and SD formats and are provided with re-clocked loop-through connectivity for connection to down-stream equipment.
‘The device provides a reliable and very cost-effective solution to the issues of interfacing SDI to audio equipment such as routers, consoles, intercoms and workstations,’ said 4HM director Craig Lovell. ‘BVE was essentially our launch-pad, not just for the product but also the new brand, and I feel we benefited greatly from our presence at the show.’
With a comprehensive range of synchronising options and switchable sample rate convertors, Sam64 is designed to reliably and seamlessly integrate into any broadcast environment where SDI embedded audio channels (consisting of discrete and/or Dolby E/D encoded signals) require format conversion.
