Product Description for the RME ADI-642 MADI Format Converter

The ADI-642, an 8-Channel format converter from MADI to AES and vice versa, is the latest addition to RMEs successful MADI series. Amongst other applications, the unit can serve as ideal AES/EBU frontend for the Hammerfall DSP MADI PCI card. Up to 192 kHz at 24-Bit are supported. Its most outstanding feature is an easy-to-use 72 x 74 routing matrix, which can assign an individual input channel to every single output channel, allowing free configuration of all 64 MADI channels and the 8 AES channels. Additional features include:

• direct support for MADI Double and Quad Wire
• Automatic Delay Compensation when using more than one unit
• Analog stereo monitor output, up to 192 kHz
• Detailed status display for MADI and AES
• Completely remote controlable via MIDI
• Transfer of MIDI data via MADI
• SteadyClock for maximum jitter reduction and clock regeneration

The compact unit with 19" width and 1 unit height serves as format converter MADI to/from AES (Schematic View). MADI handles 64 channels of 24-Bit audio at sampling frequencies up to 48kHz, 32 channels up to 96kHz, and 16 channels up to 192kHz. All channels are transferred across a single cable, either coaxial (BNC) or optical network cable. In both cases, cable lengths of more than 100 meters can be achieved. The AES/EBU channels are provided via 4 XLR inputs and outputs, respectively. The ADI-642 accepts 56 channels and 64 channels as well as 96k frame at its input, and can be set to generate those formats at its output. This way the ADI-642 even serves as perfect interface between otherwise incompatible MADI devices.
