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)

18 November 2013 Question by: Rapid Customer | Product code: 70-0180
Q. Can the amplifiers run on 12v? Will they need a heatsink if it is possible? Many Thanks JW
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.

14 November 2011 Question by: Rapid Customer | Product code: 70-0180
Q. What are the specific sizes of the components? (i.e speakers, etc...)
A. Hi Benjamino, Thanks for your question. Speaker 65mm across with a height of 20mm. Pcb board is 43mm X 55mm with a total height of 20mm.

Used this circuit for GCSE project and it worked first time with excellent sound, but you need to use a better quality speaker.

This is great, I used it for my GCSE project and it worked perfectly for my 2 pioneer speakers.
