8 AES HD/SD De-Embedder

The ADX-1881 is a high-quality AES de-embedder designed to extract eight (8) 24-bit 48 kHz digital audio signals, Ancillary time code (ATC), longitudinal time code (LTC) and ancillary data from a single SMPTE 292M HD-SDI or SMPTE-259M-C SD-SDI signal. The ADX-1881 will output audio silence with a loss of the input signal. A delay of up to 6 fields can be added to the audio. The ADX-1881 has a built-in audio test tone signal. The ADX-1881 provides automatic input format detection as well as automatic equalization. A serial data signal (RS-422) output is available to provide Dolby E metadata output or simply to output a serial RS422 signal. Two GPI outputs will recreate the GPI activated by the AMX card. By combining AMX and ADX cards at each end a full duplex link may be established. The ADX-1881 is designed for the DENSITÉ frame.
