Velleman 7W Mono Audio Amplifier Solder Kit
• Amplify a weak input signal on an audio device
• The circuit is protected against overheating and short circuits
• Easy and fun to solder with 19 parts
• Requires a 8-18V DC power supply (not included)What can do with this kit?
Get great sound out of your mono audio devices with this 7W audio amplifier (manufacturer’s code K4001). Send your audio to an active speaker, subwoofer or other devices. The circuit is capable of producing 7W peak output or 3.5W RMS output, and works on a single channel input ideal for mono devices like microphones. This kit is capable of boosting signals up to 20Hz-20kHz frequencies, the normal human hearing range. With a compact 35mm x 55mm circuit, this kit will fit in almost anywhere. With 19 parts, this is a great kit for those looking to get more practice with soldering. This kit is also available to buy prebuilt (order code N08AA).
What can I learn from this mono pre-amp kit?
Practise soldering and learn about electronics and circuits with this pre-amplifier kit. It uses resistors, capacitors, and an integrated circuit (IC) chip, and will help you learn how to connect a circuit. The circuit is designed to take a small signal and amplify it without changing the pattern. This kit is built around the TDA2003 IC chip. Since the IC chip creates heat, the kit also includes a heatsink to dissipate the energy. This circuit has protections against short circuits as well as overheating. This kit requires a soldering iron and solder, and may require wire cutters.
What can I do with this kit?
A great kit for the audio enthusiast or those looking to improve their soldering skills. Putting the kit together is just the start – you may want to create an enclosure (not included) for the kit to protect the electronics, just take care not to block the inputs and outputs. You can also add on convenient socket/plug for your inputs and output so you can plug in quickly and easily. You could even add a potentiometer (not included) and create a volume control. This kit requires a DC 8-18V power supply (not included) and a 15V power supply is recommended.
