Overview
STABP01 DIGITAL PROCESSOR s BASH® LICENCE REQUIRED DESCRIPTION The STABP01 processor is used to control the BASH® Digital Converter.
When used in conjunction with BASH® amplifiers a fully integrated high efficiency power amplifier is realized.
By analyzing the audio input, the Processor determines the appropriate on/off events and generates a digital pulse for the Digital Converter.
The converter turns this pulse into a power signal that feeds the power amplifier.
The feedback system allows the processor to constantly adapt to the audio signal and regenerate the digital pulse thereby maintaining a constant voltage across the output devices.
