Operation
The PDM 1383 functions as a 4 channel embedder and de-embedder.
The module will also support simultaneous embedding and
deembedding where audio can be deembedded from the selected
audio group before overwriting it with new audio.
Rotary switches are provided for embedded audio group selection as
well as audio level, levels can be preset to an FS (full scale) level for
balanced audio, or line level for unbalanced audio.
(NOTE: An audio “group” is 2 x AES = 4 channels of audio)
Connections
All connections are clearly indicated on the
module. Analog audio I/O connections can
be made two ways, by directly wiring
connections to a suitable male 25 pin SubD
connector, or by using the supplied 25 pin
SubD PCB adapter with screw terminals.

Settings
A dip switch is provided for
module configuration.
Settings are indicated on the
module and self explanatory.
The “Auto Black” function will automatically output a black test signal on
the SDI output if the input video is lost. This allows for an uninterrupted
audio connection. Alternatively this mode can be used for analog audio
transport only.
Bidirectional Master
If a pair of modules are being used to transport audio (only) between
two locations then bidirectional functionality is possible when one of
the two modules is set to be the “Bidirectional Master” using the dip
switch. Please refer to the diagram.

Only one end needs to be set as the Bidirectional Master, the other end
can be a PDM 1383, PDM 1382 or even a PDM 1284 for AES I/O
Cascading for More Audio Channels
All of our yellobrik Embedders/Deembedders can be cascaded to add
more audio channels. In the case of the PDM 1383 up to four modules
can be cascaded to support the full payload of 16 analog audio
channels. The configuration below shows two modules cascaded for 8
channels.

SDI video could also be used)

NOTE: The module is designed for balanced audio signals. If using unbalanced audio
then the audio levels and full scale calibrations will not be accurate, there may also
be more noise on the signal.
Note:
It is not possible
