  3. DCN Next Generation Technology • Digital signal processing and transmission via an advanced digital technology. • Signal transmission and processing is handled by proven digital audio technology. This technology is implemented into dedicated ICs handling digital audio processing as well as analogue-to-digital and digital-to-analogue conversion. • Other ICs specially developed for this application include dedicated protocol converter chips. The system combines the highest levels of functionality and performance in an extremely compact design. I&U Instructions DCNNG SA SD Technology

  4. DCN Next Generation Technology • Other ICs specially developed: • ACN-1 (Audio Communication Network-1) is a Slave Protocol Transceiver located in all active DCN-units • Receiving single-channel downlinkAudio-data and Control-data • Transmits single-channel uplinkAudio-data and Control-data. • ACN-2 Is a Master Protocol Transceiver located only in the CCU • Transmits multi-channel downlinkAudio-data and Control-data • Receives multi-channel uplinkAudio-data and Control-data from all the slaves.
