NPCP215F Audio Enhancing Engine and Power Amplifier Family General Description The Nuvoton NPCP215F device is a member of Nuvoton Sound Enhancing family optimized for TV applications. The NPCP215F integrates a Class-D power amplifier with Waves Maxx Audio-3 sound enhancement algorithms. These are proprietary, patented, psychoacoustic algorithms that pensate for the acoustic limitations of smalldimensioned consumer electronics devices and speakers. Maxx Audio-3 algorithms enable reproduction of rich content, with a wide dynamic range and a full frequency range, on a limited audio system. For low-frequency reproduction, Maxx Bass uses a patented psychoacoustic technique to create a perceived low bass, which can be extended up to 1.5 octaves lower than the original. This technique reproduces full and rich sounding bass tones. Power handling is done by Maxx Volume, which utilizes the power amplifiers and speakers to their full extent yet avoids clipping and distortions. The Maxx Audio-3 software suite provides additional algorithms that enhance the overall sound quality, such as Maxx3D, which widens the stereo image, and Maxx Treble for reproducing crystal clear high frequencies. To design a resonance-free audio system, Maxx EQ provides a flexible equalizer with 20 bands. Specifically designed for devices such as TV, Maxx Leveler maintains a constant level of output for any given content. This feature is useful for maintaining the same volume during mercials or when switching TV channels. The Maxx Audio Graphical User Interface (GUI) enables sound engineers to easily tune the device and customize presettings for different audio products.
