The Lynx Technik AG yellobrik PDM 1284 B AES Audio Embedder/De-Embedder is designed for a wide range of SDI video formats (up to 3 Gb). It supports unbalanced AES3id audio I/O using BNC connectors.
The AES 1+2 and AES 3+4 are independent channels; this means that in addition to being used as a 4 x AES embedder/de-embedder, the unit can also function as a 2 x AES embedder/de-embedder. Each channel is configured using the dip switches and rotary switches. You can select audio groups using the rotary switches and embed or de-embed additional audio groups by cascading two modules together.
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 Audio Embedder/De-Embedder 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. This 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.
A selectable 1 kHz test tone generator is integrated for audio testing purposes. The module includes an LED for video present indication as well as 2 multi-color audio status LEDs.
