The ADX-1901 is an advanced, high-quality 24-bit 48 kHz analog audio de-embedder designed to extract eight analog audio signals from a 3G/HD/SD video signal. The ADX-1901 can process the eight audio de-embedded channels with functions including level, channel shuffling and mixing. The loudness measurement features provide for the measurement and logging of up to eight audio programs with iControl Loudness Monitoring software to analyze and report compliance with respect to various loudness legislation around the world. Additionally, a delay of up to 2.7 seconds can be programmed independently per de-embedded audio channel to provide lip sync correction.
