Solid State Logic SDI-MADI

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.
Features
  • 4 x SDI inputs on 75 ohm BNC connection. 16 audio channels per input
  • Auto-detection of SD/HD/3G input format
  • Active loop-through of each input to 75 ohm BNC output connection
  • Full Dolby E/Dolby Digital transparency for loop through
  • 32 x AES digital audio output via 37 pin D-Sub
  • Dual 64 Ch MADI digital audio output via ST Multimode Optical and Coax
  • Front Panel LED status indication for PSU, SYNC, SRC and SDI Lock
  • Comprehensive sync options (Wordclock, AES, Black and Burst, SDI1 - 4)
  • Wordclock and AES sync outputs
  • On-board sample rate convertors (SRCs), enabled locally or remotely via GPI
  • Dual power supplies, with separate IEC mains connectors
  • Optional 19" AES Signal Breakout panel providing AES3-id outputs on 32 x BNC connectors (75 ohm)
