Velleman Mono Pre-Amplifier Solder Kit
• Amplify a weak input signal on a microphone or audio device
• Output at line level for use with an amplifier or subwoofer
• Simple and fun to solder with 20 parts
• Requires a 10-30V DC power supply (not included)What can do with this kit?
Use this mono pre-amplifier kit (manufacturer’s code K1803) to boost your input to line level and use your microphone or other low signal device with a subwoofer or amplifier. The pre-amplifier kit amplifies a single channel, perfect for use with mono audio equipment like microphones or guitars. This kit works on the 20Hz-20kHz frequencies, the normal human hearing range. With a compact 30mm x 40mm circuit, you can fit this kit in almost anywhere. With 16 parts, this is a great kit for those looking to get more practice with soldering.
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 a resistor, capacitors, microchip and a potentiometer, and will help you learn how to connect a circuit. The circuit uses basic components including resistors and capacitors to amplify a signal, and uses a microchip to direct the circuit so that the output pattern is the same and the strength is increased. This kit requires a soldering iron and solder, and may require wire cutters.
How easy is this kit to solder?
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. Alternatively, you can add a convenient socket/plug for your inputs and output so you can plug in quickly and easily. This kit requires a DC 10-30V power supply (not included).
