ADX-1842
HD/SD 4 AES De-Embedder
The ADX-1842 is a high quality de-embedder designed to extract up to four AES 24-bit 48 kHz digital audio signals from a single HD/SD serial digital video signal. A unique feature is its ability to extract timecode, a serial RS-422 data signal and two GPI status signals from the video signal. The module supports signal presence detection, remote reporting, and local or remote configuration and control, and features a built-in audio tone test signal.
