Abstract

This project is an integration of a power amplifier with many other added function. The amplifier will have the ability to sense a person passing in front of it, and reduces its audio level (volume) to a certain level. To make the amplifier more convenient to people, a handclap function is also added, so that when a clap is detected, the radio switches to another broadcasting channel without having that person to get close to the amplifier. However, channel switching button is also built since both autovolume and handclap function can be turn on and off depending on the user. To expand the function of the amplifier in the future with its integration with DSP, a source selector is built so that there are multiple audio source can be received, but only one is projected as output at a time. Besides making people more free to remote control device, this project is also hoped to give a new idea to the control system and audio technology.
