8 AES HD/SD Embedder with AFD

The AMX-1881 is a high-quality embedder which embeds up to eight (8) AES 24-bit 48 kHz digital audio signals into a single HD/SD serial digital video signal. The module offers audio and video signal presence detection and reporting, and local or remote configuration and control. A unique feature is its ability to embed Time Code, a serial RS-422 data signal (including Dolbytm Metadata) and two GPI status signals into the video signal. The card also serves as a VLI and AFD inserter for an SD or HD signal. The card has built-in audio tone, Time Code and video color bar test signals. The AMX-1881 is designed for use in the DENSITÉ 2 frame.
