INSTALLATION
Make sure the following items have been shipped with your
AMX-1842. If any of the following items are missing,
contact your distributor or Miranda Technologies Inc.
* AMX-1842 Digital Audio Embedder
* AMX-1842 rear panel (see figure for options)
The AMX-1842 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 AMX-1842. See the DENSITÉ Frame manual for
detailed instructions for installi ng cards and the ir
associated rear panels.
OPERATION
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 AMX-1842 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).
: Factory default. User configurable
A “Flashing Yellow” Status LED indicates that the SELECT
button on the front panel has been pushed, and the
controller display and control panel are now assigned to
this card. The LED color assignments for some error

Guide to Installation and Operation
The AMX-1842 has multiple audio and video inputs and
outputs, and making space for all the necessary
connectors at the rear of the frame requires a double-width
rear panel.
When a double–width rear panel has been installed, the
AMX-1842 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.
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:
Use the local control panel to access the detailed status
report shown in the STATUS menu on page 3.
Operating Parameter Adjustment
The AMX-1842 has operating parameters which may be
adjusted at the controller card interface. After pressing the
SELECT button on the AMX-1842 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.

locks both channel level sliders together, so that moving
one slider moves the other one as well. The mute option
mutes both audio channels completely. The swap option
interchanges the right and the left audio channels. The
sample rate converter can be set to either auto or off.
While in auto mode, the sample rate conversion process is
automatically turned off upon detection of non-pcm channel
status.
The Delay tab allows the user to set the delay of the AES
audio as it passes through the embedder. The delay is
selectable between none, and a number of video frames (0
to 3 frames in 0.5 frames steps).
