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.

Note: You will only have to use the build instruction to connect the jack lead, power lead and speakers.

Features:

  • 1W per channel stereo amplifier.

    A:

    Hi Luke, The stereo amp kit doesn’t have a volume control one, however you can add one by using a dual swipe potentiometer and connecting one side to the source input signal, the other side to ground and the middle to the input on the PCB. There is a section on page 4 in the following document which shows how to add a power switch to the circuit, https://www.kitronik.co.uk/pdf/2136_stereo_amplifier_essentials_2_0.pdf. Lastly the kit doesn’t come with a battery cage as it can be powered from a 9V PP3 battery, but it can run on a voltage range of 2-15V’s.

    A:

    The kit is supplied with the amplifier IC, which is already programmed. With the pre-built kit the students would only have to solder the power supply, speaker and audio input connections to the board. They would also need to place the amplifier IC into the IC holder which is located on the board.

    A: You've given a capacity for the Mini Encapsulated Solar Cell so I'm assuming it's a solar cell/battery combination unit. Without knowing more about the unit I can't tell you much for certain. With 5V though you may be better off using our 3W amplifier (product code : 2158), it is designed to run from 5V whereas this stereo amplifier works best from 12V. With the 3W amp you'd be able to just connect your solar battery unit directly. You may or may not still have some issues at maximum volume depending on if the 2.5W rating of your battery is a peak maximum or continuous maximum. But as I said before I can't say for sure without more details. If you email the technical spec of the solar battery unit to support@kitronik.co.uk I can take a look.

    A: Hi Jon, It's a 2 minute job to attach the speakers. 10 solder joints including both the speakers and the PP3 clip. There is a 10% discount on this kit if you order over 300 units. It is explained in more detail here https://www.kitronik.co.uk/ordering/bulk-buy-discount-for-kits/

    A: Hi Armenay, we have a standard and deluxe stereo amp but we have only ever done one FM radio kit. Hope this helps!

    A: I don?t think this kit would work with 8 speakers. It can only output about 1W per channel, if you had 4 speakers per channel this would only allow 0.25W per speaker, this isn?t really enough to drive the speakers. Also speakers generate a lot of electrical interference as the cones move in and out, having many connected to the same channel would distort the sound coming out and cause a lot of problems. The difference between the deluxe amp and the stereo amp is that the deluxe amp has volume control and a power switch. Both models have a pre-built version which comes with all the parts soldered in.

    A: Yes the IC will drive a four ohm load (two 8 ohm speakers in parallel) so you can connect two speakers to each output. However it won?t be any louder or any better quality audio. If you want an on board on off switch then the deluxe amplifier might be a better option see: https://www.kitronik.co.uk/products/project-kits/ic-based-kits/deluxe-stereo-audio-amplifier-kit/ If you just want to add a power switch have a look at the following tutorial: https://www.kitronik.co.uk/resources/tutorials/how-to-add-a-power-switch-and-led-to-your-project-kit/ (No need to fit the LED & resistor if you don?t want them) If you need extra speakers see: https://www.kitronik.co.uk/products/components/audio/speakers/66mm-speaker-pack-of-10/

    A: You would need to be able to get access to the audio output from the toothbrush which I suspect may involve destroying it, not that I?ve seen one to be able to state with that any certainty. If you can get to the 0V signal and the audio signal then yes you could connect it to this kit and use your tooth brush as an audio source.
