The AMX-1842 from Grass Valley, a Belden Brand, is a high-quality embedder which embeds up to four AES 24-bit 48kHz digital audio signals into a single HD/SD serial digital video signal. It includes audio and video signal presence detection and reporting, and local or remote configuration and control. A unique feature is its ability to embed timecode, a serial RS-422 data signal and two GPI status signals into the video signal. The card has built-in audio tone, timecode and video color bar test signals.
