The Provideo ADE-104N eurocard AES serial digital audio de-embedder provides a broadcast quality solution to the de-embedding AES digital audio that is embedded in the serial digital data stream. With the optional plug-in ADE-DB daughterboard AES to stereo audio DAC card, the two recovered AES channels are converted to broadcast audio outputs of stereo quality.

The ADE-104N has both unbalanced 75Ω or balanced 110Ω AES digital audio outputs per group.  Automatic cable equalisation to SDI input is provided, and typically 250 metres of high quality cable at 270 Mb/s can be equalised.

The ADE-104N can selectively de-embed one of four groups of AES signals that may be embedded in a SMPTE 259M serial digital signal. Two AES signals are recovered within a group selection. Group selection is by way of either a front panel switch or via a remote 9-pin D-type control connector. LEDs on the front panel confirm which group or groups have embedded AES audio.

An optional ADE-DB plug-in dual AES to analog audio stereo card is available for applications where broadcast audio outputs are required. Two stereo outputs are located on the rear panel. The nominal output level is set to +4 dBu. From this nominal level, on-card gain controls enable each channel’s gain to be increased or decreased by 6 dB. Full 24 bit broadcast stereo digital to analog converters are used offering excellent  signal-to-noise, extremely low clock jitter and zero phase error between channels.
