The AP 84 DSP utilizes the ADI SHARC 21489 processing chip, which is based on a 64-bit floating-point DSP engine and a powerful digital audio signal processing platform. This series of products provides a wide range of digital processing tools for audio system design, configuration, and optimization. The DSP Controller software allows for complete control and management of the entire DSP series and all its processing functions, including AFC, AEC, ANS, ANC, AM, AGC, Ducker, PEQ, GEQ, delay, crossover, and more. The intuitive graphical user interface is a key component of the DSP Controller software, providing a quick and convenient view of all signal channels in a single window. In this user-friendly environment, audio system designers or installers can easily view and adjust input levels, audio DSP processing parameters, mixing relationships, and output levels.
