The ADX-1881 is a high-quality AES de-embedder
designed to extract eight (8) 24-bit 48 kHz digital audio
signals, Ancillary time code (ATC), longitudinal time code
(LTC) and ancillary data from a single SMPTE 292M HDSDI or SMPTE-259M-C SD-SDI signal. The ADX-1881will
output audio silence with a loss of the input signal. A delay
of up to 6 fields can be added to the audio. The ADX-1881
has a built-in audio test tone signal. The ADX-1881 provides
automatic input format detection as well as automatic
equalization. A serial data signal (RS-422) output is
available to provide Dolby E metadata output or simply to
output a serial RS422 signal. Two GPI outputs will recreate
the GPI activated by the AMX card. By combining AMX and
ADX cards at each end a full duplex link may be
established.
.
The ADX-1881 is designed for the DENSITÉ frame.

INSTALLATION
Make sure the following items have been shipped with your
ADX-1881. If any of the following items are missing,
contact your distributor or Miranda Technologies Inc.
The ADX-1881 and its associated rear connector panel
must be mounted in a DENSITÉ frame. It is not necessary
to switch off the frame’s power when installing or removing
the ADX-1881. See the DENSITÉ Frame manual for
detailed instructions for installing cards and their
associated rear panels.
The ADX-1881 has multiple inputs and outputs, and
making space for all the necessary connectors at the rear
of the frame requires a double-width rear panel.
Overview
The DENSITÉ frame incorporates a central controller card,
located in the center of the frame, which is equipped with
an LCD display and a control panel. The controller handles
error reporting and local and remote control for all cards
installed in the frame. The display and control panel are
assigned to the card in the frame whose SELECT button
has been pushed.
Status Monitor LED
The status monitor LED is located on the front card-edge of
the ADX-1881 module, and is visible through the front
access door of the DENSITÉ frame. This multi-color LED
indicates module status by color, and by flashing/steady
illumination, according to the following chart (which also
indicates fault reporting for this card on the DENSITÉ
frame’s serial and GPI interfaces).

A “Flashing Yellow” Status LED indicates that the SELECT

controller display and control panel are now assigned to
this card.
ADX-1881 HD/SD 8 AES Disembedder
Guide to Installation and Operation
When a double–width rear panel has been installed, the
ADX-1881 must be installed in the right-most of the two
slots covered by the panel in order to mate with the panel’s
connectors. If it is placed in the wrong slot, the front panel
LED will flash red. Move the card to other slot for correct
operation. No damage will result to the card should this
occur.
In addition, the ADX-1881 requires an external mounting
bracket and breakout panel. The breakout panel is
connected to the rear panel via a multi-conductor cable
fitted with two male connectors. The ADX-1881’s inputs
and outputs occupy both panels.
See the annex at the end of this manual for the
specification of the cable to interconnect the rear panel and
the breakout panel.
The LED color assignments for some error conditions can
be reconfigured by the user (see the chart and menu for
details).
User Interface
Pushing the SELECT button will cause the on-card
STATUS LED to flash yellow, and the card identification
and the current status will be shown on the controller card’s
display. The STATUS LED will revert to it’s normal state
upon a second push of the button, or after a short delay.
The messages which may appear are shown in the top line
of the menu chart on page 3
Example :
SELECT button pushed twice when there is no input
signal connected to the rear panel and the LED is
steady red:
A D X - 1 8 8 1
Use the local control panel to access the detailed status
report shown in the STATUS menu on page 3.
Operating Parameter Adjustment
The ADX-1881 has operating parameters which may be
adjusted at the controller card interface. After pressing the
SELECT button on the ADX-1881 card, use the keys on
the local control panel (described in the Controller card
manual) to step through the displayed menu and adjust the
parameters. The menus are shown below.

The header gives the product’s name, and identifies the
slot in which it is installed in its Densité frame. At the left is
a status icon whose color shows the overall status of the
ADX-1881:
Green = OK
Yellow = warning
Red = error
The 3 icons monitor specific aspects of the operation of
the ADX-1881. Move the cursor over an icon to see its
current status in the message area below the icons. If
there is an error status, the message will automatically
appear.
•The first icon shows whether the remote control of
this ADX-1881 device is enabled or not.
•The second icon shows the input status. Move the
cursor over the icon to display the video format.
•The third icon indicates if audio or video test signals
are active.
Audio
The Audio tab shows the audio groups detected and
provides resources for managing the audio processing of
the ADX-1881.
Group Detected: indicates embedded audio groups in the
ADX-1881 HD/SD-SDI input.
To configure the AES digital audio signals, access the
AES1 to 4 tabs. There are two sliders (left and right for
Page 8 of 12 ADX-1881
stereo sound) available to set the level from -96 dB to +12
dB in steps of 0.5 dB. To invert the selected audio channel
phase, check the Phase Invert boxes. The Lock option
locks both channel level sliders together, so that moving

The Encoding status monitors the audio channel encoding
type. The possible values are PCM or NPCM (non-PCM).
Metadata
The Metadata tab offers setting options for the output LTC
signal for the embedded time code, RS-422 signal, GP1
and GP2.
The LTC Output window allows the user to select the
source of the time code appearing at the LTC output (ATC,
DVITC). For an HD-SDI input, using the HD ATC Select
drop down menu, select the ATC signal to be disembedded
(first ATC or second ATC).
For an SD-SDI input, using the SD DVITC line drop down
menu, select the desired line to be disembedded. If the
input DVITC is in a 525 format, the available selections will
be auto or lines number 10 to 20. If the input DVITC is in
625 format, the Auto option remains, but the line numbers
vary from 7 to 22.
