NPCA110T Audio Enhancing Engine and DAC

Product Brief

November 2011

Revision 1.0

General Description

The Nuvoton NPCA110T device is a member of Nuvoton’s

Sound Enhancing family optimized for TV applications.

The NPCA110T integrates Waves MaxxAudio 3 sound

enhancement algorithms. These are proprietary, patented,

psychoacoustic algorithms that compensate for the

acoustic limitations of small CE devices.

The MaxxAudio 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, MaxxBass 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 MaxxVolume, which utilizes the

power amplifiers and speakers to their full extent yet avoids

clipping and distortions.

The MaxxAudio 3 software suite provides additional algo-

rithms that enhance the overall sound quality, such as

Maxx3D, which widens the stereo image, and MaxxTreble

for reproducing crystal clear high frequencies. To design a

resonance-free audio system, MaxxEQ provides a flexible

equalizer with 10 bands.

Specifically designed for devices such as TV, MaxxLeveler

maintains a constant level of output for any given content.

This feature is useful for maintaining the same volume dur-

ing commercials or when switching TV channels.

The Maxx family of devices includes:

■ High-performance, 24-bit audio enhancing engine pre-

programmed with Waves MaxxAudio 3 algorithms

■ Optional Audio DAC

■ Optional Audio ADC

■ Digital I/O and other features for high-performance

audio systems

The MaxxAudio Graphical User Interface (GUI) enables

sound engineers to easily tune the device and customize

presettings for different audio products.
