Note. Please check connected peripheral equipment before using the P DM 5240 to
make sure the audio ports of the P DM 5240 are configured correctly, e.g. an output
is not connected to an output of another device, this might damage the equipment.
Product Description
The P DM 5240 Module is a high performance SD/HD/3GBit/s audio embedder and
deembedder for AES digital audio streams.
Four external AES ports are provided which can be switched by the user individually as
AES inputs or outputs. These AES ports are provided as balanced AES3 audio inputs or
outputs on a 25 pin SubD connector (P DM 5240 D) and as unbalanced AES3id audio
inputs or outputs on 75Ohm MiniDIN connectors (P DM 5240 U).
All deembedded and external AES input streams can be processed in an audio
processing stage incl. mono gain, stereo downmix, mute, overload and silence detection
as well as a 1kHz test tone generator.
DolbyE processing is included in the audio processing stage, i.e. one encoded DolbyE
stream can be synchronized to the SDI clock domain and the Guard Band is
automatically aligned.
NOTE: The P DM 5240 is delivered from the factory preconfigured with 2 external AES
Inputs and 2 external AES outputs. See page 24 for information on re-
configuration of the signal direction of each AES port.
