Product Description
The P MX 3312/3313 D is a high quality analog
Audio multiplexer (Audio Embedder) designed
primarily for broadcast and professional
applications.
The Module accepts 2 external analog Audio
Stereo inputs (combined into one audio group)
and multiplexes this into the incoming SDI video
input. Group insertion is selectable (1 through 4).
Four separate SDI outputs of the video, with
embedded audio are provided. Existing audio
groups can be overwritten, deleted or passed
transparently. Four separate SDI outputs of the
embedded signal is provided which could be used
to cascade several modules for additional audio
group insertion. The Module uses Sub D
connections for audio and standard 75-Ohm (BNC)
interconnections for video.
The P MX 3312/3313 has a variety of features, which
include:
•User selectable audio groups. (1…4)
•525 and 625 line standard. (auto detect)
•Supports 4:3 / 16:9 aspect ratios.

Stand Alone Operation
The P MX 3312/3313 D MiniModule can be used in a
stand alone application. There are two options for
the use of the module in this way.
a) Using the R FR 3005 Rack Frame 1 option. This
allows up to any 10 of the MiniModules to be
secured onto a rack frame assembly for 19 inch
rack mounting. This keeps the modules secured,
organized and out of the way. The R PS 3001
power brick option or the R FR 3010 option is
required to power each module. Please refer to
the R FR 3005 Reference Manual supplied with
this option for more details.
b) Single Use. The MiniModule can be powered
independently with the R PS 3001 option and
used in any location where this functionality is
required.
Caution. Care needs to be taken
when using the module in this way, as
it is not physically secured. Keep the
module away from the floor to avoid
the risk of someone stepping or
tripping on the unit, and locate the
unit away from excessive sources of
heat and any sources or moisture.
If using more than one MiniModule in any
installation, the R FR 3005/3010 Rack frame
combination is highly recommended.

Reference Manual P MX 3312/3313 D Version 3.0
Page 14
Multiple Units
Most applications will require more than one
MiniModule, which can include any of the
available Series 3000 MiniModule product range.
There are two options for mounting multiple units.
a) Using the R FR 3005 Rack Frame option. This
allows up to any 10 of the MiniModules to be
secured onto a rack frame assembly for 19 inch
rack mounting. The R PS 3001 power brick
option or the R FR 3010 option is required to
power each module. Please refer to the R FR
3005 Reference Manual for more details.
b) Using the R FR 3010 Rack frame extension
option. Can be combined with the R FR 3005
Rack frame option. Each module plugs into a
connection bus, which provides common
power for all modules. (no R PS external power
supplies are needed).
The very small size and density of the MiniModules
combined with the available rack frame options
allows the addition of a complex and custom signal
distribution system without taking any additional
front rack space. The rack frames are designed for
installation in the back of 19-inch racks where there
is normally plenty of available space. Ideal for
mobile truck installations and facility expansions
where space is at a premium.

Electrical Installation
Stand Alone Operation
The MiniModule requires the R PS 3001 power brick
option for stand-alone operation. Three versions are
available: R PS 3001 E for European markets, R PS
3001 U for the US markets and the R PS 3001-3 desk
power supply. Please ensure you have the correct
power option for your region. The connection to
the module is made with a small 5-pin connector,
which has a twist bayonet securing system. Please
make sure the connection is solid and locked in
place. A strain relief is included within the module
to prevent excessive strain on the connection.
Signal connections should be made with care,
please ensure connections are correct and
compatible equipment is feeding / receiving the
signals from the module or damage can result.
Caution. Only use the optional LYNX R PS
3001 power modules. Ensure the 5-pin
power connector is locked securely in
place.
Caution. Care needs to be taken when
using the module in this way, if it is not
physically secured. Keep the module
away from the floor to avoid the risk of
someone stepping or tripping on the unit,
and locate the unit away from excessive
sources of heat and any sources or
moisture.

module. This is because all settings can be
changed from the remote control system or via the
Service Adapter. This overrides the local dip
switches regardless of Switch 1 ON/OFF setting. To
ensure the module reads the local dip switch
settings it is recommended to toggle Switch 1 ON-
OFF-ON before making any local changes to the
dip switches.
Dip Switch 2
20 / 24 bit operation. When set to ON the AES audio
output will be 24 bits wide (which is normal). When
