AES audio Embedder / De-embedder (unbalanced AES)
The PDM 1284 B is a versatile 3G-SDI AES audio Embedder and De-Embedder. It supports unbalanced AES3id audio I/O using 75 Ohm BNC connections.
Audio groups are selected using the rotary switches, it is possible to embed and de-embed additional audio groups by cascading modules together. Simultaneous embedding and de-embedding means the module de-embeds and output the audio from the selected audio group before overwriting the group with a new audio source. The module automatically detects audio formats and will deactivate the sample rate converters to preserve encoded bit streams such as DolbyE.
The “auto black” mode uses a black video frame when no SDI input is present. This allows the module to embed audio even when no video source is available. This mode is useful for “audio only” application. A 1kHz test tone generator is included for audio testing purposes.
The module is fully compatible with yelloGUI and LynxCentraal, which provide access to a host of additional internal settings including manual insertion of metadata (AFD,WSS,VI). It can be configured, controlled and updated using Windows or MacOS.
