STABP01

DIGITAL PROCESSOR

s

BASH廬 LICENCE REQUIRED

DESCRIPTION

The STABP01 processor is used to control the

BASH廬 Digital Converter. When used in conjunction

with BASH廬 amplifiers a fully integrated high efficien-

cy power amplifier is realized.

By analyzing the audio input, the Processor deter-

mines 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 pro-

cessor to constantly adapt to the audio signal and re-

generate the digital pulse thereby maintaining a

constant voltage across the output devices.
