Authors: Mendenhall, Eric

AES Convention 113 · Paper 5694 · October 2002

Abstract

Audio power amplifiers have typically been supplied power by the simplest possible means, usually an offline supply with no line or load regulation, most commonly based on a line frequency transformer. Even modern amplifiers utilizing switchmode power supplies are usually designed without line or load regulation. The exception has been made for high-end audiophile amplifiers. The pros and cons of a regulated power supply are investigated.
