The Lynx Technik AG yellobrik PDM 1383 Analog Audio Embedder / De-Embedder is designed for a wide range of SDI video formats (up to 3 Gb). It supports analog audio I/O using a 25-pin D-Sub connector.The audio groups can also be selected using the rotary switches. Additionally, you can embed or de-embed additional audio groups by cascading modules together. It supports simultaneous embedding and de-embedding that allows the module to de-embed and output the audio from the selected audio group before overwriting.An optional fiber I/O adds fiber transceiver functionality for embedding and de-embedding directly from the fiber I/O. The module features a special mode of operation that allows bidirectional transfer of audio (only) signals using 2 modules.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. Simultaneous embedding and de-embeddingSDI video formats up to 3 Gb (1080p60)Four analog audio inputs and outputsSelectable full scale audio level or line level I/OSelectable audio groupsOptional fiber I/O connectionBidirectional audio transport over fiberIntegrated test tone generatorAuto black if no video presentSelectable SDTV 24-bit modeVideo present and audio status LEDs
