About this document
Xs1200 Amplifier Service Notes by Dimitris is a document available to read on EtoBox.
This document provides a summary of the circuit description and service notes for the Xs1200 amplifier. It describes the switching power supply, which converts mains power to various DC voltages using a bridge rectifier, reservoir capacitors and transformer. It then summarizes the design of the amplifier circuit, including the class A driver stage and class AB output stage. It notes that muting is controlled by switching a current source on or off using a transistor controlled by the microcontroller.
