Product Description

Details

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, it provides a cost-effective and reliable interface between SDI video bitstreams and 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 standards while SDI status information is presented on the front panel. Each SDI input has a dedicated loop-through output, for connection to downstream equipment.

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

Being fully Dolby® transparent, SAM64 can be deployed in any facility using Dolby E, Dolby Digital or Dolby Digital Plus encoded material.

Installation into any system is impressively fast and exceptionally easy. Quite simply connect up the SDI, select your sync source and the outputs are there.

With its compact and sturdy build quality, SAM64 continues to see use at many of the world’s major sporting events.

Applications include live production studios, outside broadcast and fly-away systems.
