PRELIMINARY
TruBass Audio Enhancement Processor
1 Overview
The
AP8111
is a bass enhancement processor based on SRS Labs, Inc.’s patented TruBass technology. TruBass is a
revolutionary psychoacoustic bass enhancement technology that provides deep, rich bass to small speakers without the need
for a subwoofer or additional extra physical components. Deep bass now becomes possible even through speakers with
limitations in driver and cabinet design. TruBass circuitry actively monitors the low-frequency content of an audio signal
and optimizes the frequency and amplitude spectrum of the output signal to enhance bass perception. For systems with a
subwoofer, TruBass complements and enhances bass performance.
TruBass is therefore most suitable for applications that use small size speakers yet need to deliver the best audio quality or
home theatre effect: Mini or Micro Stereo Sound Systems, TV, CD, Boombox, Car Audio, DVD Receiver, Set-Top-Box, and
other compact hi-fi systems such as Discman, MD, MP3 player, as well as PCs.
