This document describes the Kitronik High Power Amplifier Kit, a project kit designed for educational use, particularly in KS3 Design and Technology lessons. It serves as both a teaching resource and a build instruction manual for constructing a stereo amplifier.
The Kitronik High Power Amplifier Kit allows users to build a functional stereo amplifier. Its primary function is to amplify audio signals, enabling connection to speakers for sound output. The kit includes a Printed Circuit Board (PCB), various electronic components, speakers, and necessary wiring. It's designed to introduce students to electronics and electronic construction, covering aspects from design and soldering to fault finding and evaluation. The amplifier circuit is relatively simple, with the core amplification handled by an integrated circuit (IC), the TDA7297. It takes an audio input, amplifies both the voltage and current, and drives two speakers. A power switch controls the circuit, and an LED indicates power status. A dual potentiometer acts as a volume control.
