4HM Limited SAM64 - SDI (3G) to AES + MADI Interface

The SAM64 is a cost-effective solution to the problem of connecting audio equipment to the SDI-based infrastructure found in many broadcast facilities today. Occupying only 1U of rack space, the SAM64 provides the interface between SDI video bitstreams and digital audio.

SAM64 extracts 16 audio channels from each of the unit’s four SDI inputs to provide a total of 64 audio channels in both MADI (AES10id-2008) and AES3 (AES3-1992) formats. All SDI inputs independently auto-sense between 3G, HD and SD standards and are provided with loop-through connectivity for downstream equipment.

With a comprehensive range of synchronising options and switchable sample rate convertors, the SAM64 is designed to reliably and seamlessly integrate into any broadcast environment where SDI-embedded audio channels require format conversion.

Broadcast-standard reliability is achieved with redundant power supplies, careful choice of components and extensive test and QC procedures. The optional 1U, 19” rack-mounting AES Signal Breakout panel (ASBO), enables the AES3-id outputs to be available on 32 BNC connectors (75 Ohms).
