AP8202
SRS WOW Audio Enhancement Processor
1. OVERVIEW
2. FEATURES
The AP8202 is an audio enhancement processor based
on SRS Labs’ WOW patented technology. WOW is a
combination of SRS 3D, FOCUS and TruBass that
creates a thrilling surround sound experience with deep
rich bass from any stereo sound sources. The WOW
technology makes up for the limitation inherent in smaller
speaker and headphone by providing a panoramic 3D
audio image that extends the sound in both the
horizontal and vertical planes well beyond the speakers
or headphones themselves.
„
SRS 3D restores the spatial cues and ambient
information that is lost during standard stereo playback.
FOCUS 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, TruBass, a patented bass enhancement
technology, offers dramatic improvement in bass tones
that are often lost during compression or unable to be
delivered by small speakers.

Application Notes
„
„
„
„
„
Tolerance of all resistors = 1%
Tolerance of capacitors = 5%
Headphone mode on/off can be controlled by SW4 independently. If Headphone mode will not be used for the
application, SW4 and R12 can be removed from PCB and then normal mode is selected automatically.
R30 and R31 should be added only when the chip’s operating voltage is below 3.3V.
The TruBass filter setting depends on the resonant frequency (fo) of the speaker. Choose different filter settings in
accordance with fo of the speaker for the actual application.
