The PDM 1284 B is a versatile AES audio embedder / de-embedder designed for a wide range of SDI video formats up to 3Gbit. It supports unbalanced AES3id audio I/O using BNC connectors.
Select audio groups using the rotary switches and embed or de-embed additional audio groups by cascading two modules together.
AES 1+2 and AES 3+4 are independent channels, which means that in addition to being used as a 4 x AES embedder / de-embedder, the PDM 1284 B can also function as a 2 x AES embedder / de-embedder. Each channel is configured using the dip switches and rotary switches.
An optional fiber I/O adds fiber transceiver functionality for embedding and de-embedding directly from the fiber I/O. When the fiber input is used both fiber and electrical SDI outputs are provided.
The PDM 1284 B automatically detects the audio format and de-selects the sample rate converters to preserve encoded bit streams such as DolbyE. (Sample rate converters can be permanently switched off using the dip switch).
The selectable “auto black” mode uses a black video frame if no SDI input is present, which allows the module to embed audio even when no video source is available. This mode is useful if the application is only transporting
multi-channel audio between locations either electrically or over fiber.
The selectable 1 kHz test tone generator is integrated for audio testing purposes. The module includes an LED for video present indication as well as two multi-color audio status LEDs.
