1 ADX-102i/104i/108i AES/EBU Demultiplexer
1.1 Introduction
The ADX-102i/104i/108i is a very high-quality AES/EBU demultiplexer series. They
are designed to extract up to eight 24-bit digital audio signal pairs from a single
SMPTE 259M serial component digital video signal. The LTC output comes from
the sampled LTC. A delay of up to 6 fields can be added to the audio and the time
code to compensate for external system timing delays. The ADX-102i/104i/ 108i
series has a built-in audio test generator as well as automatic 525/625 input
detection. In addition, these modules supports full EDH monitoring.
Audio groups are normally embedded into the HANC area of the 4:2:2 signal per
SMPTE 272M. Miranda has expanded on this capability by permitting embedders
to be cascaded and to also embed audio groups into time slots in the active picture
area.
The ADX-102i/104i/108i are members of the
imaging family of digital video
modules and therefore require the imaging Quartet-A-75, Quartet-A-110 or the
imaging Symphonie frame with Symphonie-R-CX, Symphonie-R-A75, Symphonie-
R-A110 or Symphonie-R-AX rear modules, for mounting and power.
