Miranda DENSITE Series Manual To Installation And Operation

Description
The ADX-1842 is a high-quality disembedder designed to
extract up to four AES 24-bit 48kHz digital audio signals
from a single HD/SD 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-1852 has all of the features of the ADX-1842,
excluding the HD/SD-SDI loop through outputs, plus it
provides an analog audio monitor output for one selectable
stereo pair of signals.
The ADX-1842 and ADX-1852 are designed for use in the
DENSITÉ frame, with the appropriate double-width rear
panel.
