Product Description

Details

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.

Features

A fully automatic input selection between optical and coaxial input offers a useful redundancy mode for critical applications. Extensive status displays give information about Lock and Sync states, audio content and the physical quality of the incoming signal


The ADI-642 supplies word clock in Single, Double und Quad Speed, distributes Double Wire 96kHz signals into the MADI data stream and to the AES ports, and even supports the double MADI sample rate (96K frame). The SyncAlign ® and SyncCheck ® technologies known from other RME products ensure perfect synchronization and clear detection of errors. Also multiple units can be stacked and operated sample-aligned, using word clock. All settings are stored when the unit is switched off


Additionally the ADI-642 features an easy-to-use 72 x 74 Matrix Router. An input signal can be assigned to every output channel, both for AES and MADI. This not only allows free signal routing during format conversion, but also forwarding and routing of signals within the same format. An input signal can also be distributed to any number of outputs. With more than one ADI-642, several MADI signals can be combined (merged) to one MADI stream


16 MIDI channels can be transferred across MADI (even with 64 audio channels). The device can be fully remote controlled and configured via MIDI, and all status displays can be queried through MIDI. Each ADI-642 can be given a separate ID, allowing separate remote controllability of various devices with only one MIDI channel
