Description

The ADX-1841 is a high-quality disembedder designed to
extract up to four AES 24-bit 48kHz digital audio signals
from a single SMPTE 259M HD serial digital video signal. A
unique feature is its ability to extract time code, a serial RS-
422 data signal and two GPI status signals from the video
signal. The module supports signal presence detection,
remote reporting, and local or remote configuration and
control, and features a built-in audio tone test signal.
The ADX-1851 has all of the features of the ADX-1841,
excluding the HD-SDI loop through outputs, plus it provides
an analog audio monitor output for one selectable stereo
pair of signals.
The ADX-1841 and ADX-1851 are designed for use in the
DENSITÉ frame, with the appropriate double-width rear
panel.

Video - Features

Serial HD-SDI input with automatic equalization for up
to 110m of cable.
Automatic detection of video input format
Two pass-through HD-SDI video outputs (ADX-1841
only)

Audio - Features

AES outputs: either 110 Ω balanced or 75 Ω
unbalanced, depending on rear panel in use
