SRS Mega WOW Audio Processor
1 Overview
The AP8102 is an extraordinary audio enhancement processor based on SRS Labs, Inc.’s patented WOW
technology. WOW is a special combination of SRS award-winning audio technologies that creates a thrilling
surround sound experience with deep rich bass from any stereo sound sources. Your audio now sounds fuller,
richer and wider. Based on the elements of the flagship SRS 3D technology, WOW restores the spatial cues and
ambient information that is lost during standard stereo playback. SRS Labs’ patented FOCUS technology also
included, helps to reposition a sound image from any non-optimally located speaker to a more optimal listening
position or height and improves clarity of sounds. In addition, bass become deep, rich and controlled even
through speakers with limitations in driver and cabinet design.
The AP8102 is suitable for applications such as TV, Mini or Micro Stereo System, MP3 Player, MD and CD
base radio-cassette. The low power and low voltage design of the chip is particularly suitable for portable devices
such surround headphone, Discman etc.
