Abstract

5.1 Sound System is a project of „Projek Sarjana Muda (PSM)‟ that includes the knowledge of the electronic specifically in circuit operation. This project requires designing and constructing the hardware for the sound system based on power amplifier, treble and bass. It will have FIVE (5) sound system speakers together with a subwoofer (5.1 channels). There are 8 circuits of amplifiers which includes the bass (low frequency) and treble (high frequency). The circuit will filter and channel the high and low frequency to the appropriate speaker. This will utilize the use of microprocessor and the speakers will collect the sound signals from CD player / tape player and Auxiliary system. 5.1 project is suitable for the sound system at home or a room with a scope area of 6 × 4 metre and with the audience of 5 to 8 audiences such as a family. From this project, the information and knowledge about the audio system and circuit involved will be analyzed like the output power and current required, the suitable speaker used, and the impedance for the speakers, before choosing the power amplifier circuit that will be used to amplify the treble and base output for both side (left and right). Then, the output from amplifier will be sending to the speaker to produce the sound needed. vi
