P A ASP TruBass Audio Enhancement Processor AP8111 PRELIMINARY 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.
