1 ADX-1101 Analog Audio De-Embedder
1.1 Introduction
The ADX-1101 is a high-quality, high-performance analog audio de-embedder designed to extract two analog audio
stereo signals from a single SDI signal. The ADX-1101 comprises an ADX-1121 card (2 AES De-Embedder) and a
DAC-1721 card (AES to Analog Audio Converter). The two cards are bundled via a special rear connector panel that
includes the necessary card interconnections, eliminating the need for external AES connections and reducing the
number of rear panel connectors.
The de-embedding process of the ADX-1101 includes automatic 525/625 detection, output audio silence generation
upon loss of SDI input, automatic equalization for up to 350 meters of Belden 1694A cable at 270 Mbps, and LTC de-
embedding. The audio processing includes 24 bit digital-to-analog conversion and individual mute and level
adjustment for every channel.
