SSL SDI Madi audio to video interface

Product Description

Cost Effective 3G SDI Audio De-Embedder

The SSL SDI-MADI 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 SDI-MADI 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. 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 SDI-MADI is designed to reliably and seamlessly integrate into any broadcast environment where SDI-embedded audio channels require format conversion.
