Aimed at Key Stage 3, the Rapid Audio Amplifier Project Kit provides teachers and students with a stimulating and inexpensive project through which to study the subject of amplification. The kits contain a comprehensive selection of components for schools working on audio related projects linked to the National Curriculum.
Students have the opportunity to build a small amplifier, which can be incorporated into a variety of product designs, e.g., as an amplifier for a personal CD / MP3 player so that they can share their music with their friends
The students have a number of design situations to select a starting point from, and they are provided with research topics and background material to help build understanding for their chosen design brief
The student notes provide material for students to explore how a range of simple amplifier circuits work
They also include guidance on the design and construction of speakers
To support students during the construction of the circuit, detailed instructions have been included on how to assemble the amplifier, and how to integrate the circuit into student designs
In addition, care has been taken, through extensive evaluation of the teaching material and PCB designs in schools, to ensure that the circuits are easy and robust enough for student manufacture
A detailed set of teacher notes is available which includes suggested lesson plans and mapping to the National Curriculum
The project notes have been designed for photocopying for class use
Teaching material is available for free download
Each kit contains the following:
TBA820M audio amplifier and IC socket
Resistors, capacitors, and LED
Switch and connecting jack socket
Connecting cable
Speaker and speaker cable
Battery clip
Each kit requires 1x PP3 battery (not included)
PCBs are available separately (not included), order code 70-0191
Q. Can the amplifiers run on 12v? Will they need a heatsink if it is possible?
Many Thanks

A. Hi J Wright. Thank you for your question. This kit uses a TBA820M as the output and this can accept between 3-16V to operate without the need of a heatsink.
