Our pre-built version of our stereo audio amplifier kit allows you to focus more on product design.
The stereo amplifier kit is supplied with all the resistors, capacitors & IC holder fitted. Students just need to finish it by connecting the jack lead, speakers & power clip to the board.
It can then be used with any personal stereo equipment, including MP3 players. It uses a NJM2073D audio amplifier IC which can output 1W per channel. The kit is supplied with two speakers and a pre-made jack plug.
It has a PP3 battery clip and can run off any voltage from 2 to 15 volts. Output power at 9V is 1W per speaker.
It works nicely off a 9V battery (not supplied) or if you want to run it of the mains why not try our 12V wall power unit.
This kit is also available in a kit version.
Note: You will only have to use the build instruction to connect the jack lead, power lead and speakers.
