— Master and slave timing support

■ I2C Interface

— Compliant with I2C-BUS Specification Revision 1.0,

1992

— Master or slave interface

— Supports 7-bit address mode

Audio Enhancing Engine

■ Processing Unit

— 24-bit accuracy

— 125 MIPs

Audio Algorithms

■ Sample frequency of 44.1 KHz or 48 KHz supported

■ MaxxBass

— Patented Waves MaxxBass psycho-acoustic bass

extension delivers a more natural sound than tradi-

tional bass boost technologies, which use EQ and

can overpower your system. MaxxBass analyzes

low frequencies to create harmonics that are per-

ceived as lower, deeper tones.

■ Maxx3D

— Maxx3D extends the span of stereo-side content

while maintaining the integrity of unprocessed cen-

ter content.

— Maxx3D for Speakers improves the stereo separa-

tion of speakers, widening the stereo field for optimal

imaging.

— Maxx3D for Headphones improves stereo percep-

tion, restoring the original listening balance to pro-

vide more natural sound.

■ MaxxTreble

— MaxxTreble delivers crystal clear high-frequency en-

hancement for increased RMS without exceeding

the system ceiling. Its proprietary algorithm restores

luster to over-compressed formats to provide the

perfect listening experience.

■ MaxxEQ

— MaxxEQ provides the ability to design EQ curves

and shape sound with surgical precision, using up to

10 programmable filters with bell, shelf, low pass,

and high pass, plus adjustable frequency, gain, and

Q parameters. MaxxEQ’s intuitive Graphic User In-

terface makes click-and-drag filter design fast and

easy.

■ MaxxVolume

— MaxxVolume is an all-in-one volume control, with

High-Level Compression to increase RMS levels,

Low-Level Compression to increase the clarity of

soft sounds, Noise Gating to eliminate signal and

system noise, and Leveling to smooth out volume

levels.

■ MaxxLeveler

— MaxxLeveler regulates the perceived volume of the

audio, keeping all audio content at the same level.

■ MaxxDialog

— MaxxDialog is a revolutionary new technology that

enables users to adjust center channel dialog levels

without affecting the rest of the audio mix. Based on

the Waves Center pro audio plug-in, MaxxDialog de-

livers clear, crisp dialog that does not disappear be-

hind loud music and effects.

■ Sub-Woofer

— Enables separating low-frequency content and di-

recting it into a third audio channel, for driving a sub-

woofer.
