K1100 Stereo Amplifier

The K1100 Stereo Amplifier Kit provides students with an engaging introduction to electronics, audio technology, and engineering design through the construction of a fully functioning stereo amplifier.

Using two TDA2822M integrated circuits, students assemble and test a stereo audio system capable of driving either a pair of included speakers or headphones. Throughout the project, students investigate electronic components, signal amplification, audio systems, circuit construction, and testing procedures while developing practical soldering and assembly skills.

Supported by a comprehensive STEM-D workbook, the K1100 offers an ideal balance of theoretical understanding and practical application. Students gain firsthand experience with real-world electronic systems while developing problem-solving, troubleshooting, and evaluation skills.

Suitable for middle and secondary school students, the project aligns strongly with Design and Technologies, Engineering Principles and Systems, and STEM education programs across Australia.
