Miranda ADX-1842-3RU 4 AES HD/SD de-embedder - ADX-1842-3RU
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. The ADX-1852 has all of the features of the ADX-1842, excluding the HD/SD-SDI loop through outputs, and it provides an analog audio monitor output for one selectable stereo pair of signals.
