• Fun and easy to solder with 13 parts
• Requires a 3-25V power supply (not included)

What can I do with this kit?
Boost your audio input with this mono pre-amp and transform a weak input to a line level output suitable for amplifiers or subwoofers. The mono pre-amplifier amplifies a single channel, ideal for mono equipment such as microphones and guitars. With a compact 42mm x 22mm board, you can fit this pre-amp in almost anywhere. With 13 parts to solder, this is a great kit for any ability level.

What can I learn from this kit?
Learn how circuits go together and practice your soldering with this pre-amp. The kit uses resistors, capacitors, a microchip and a potentiometer to amplify an input signal without changing its pattern. The amount the signal is amplified by depends on the signal and the power that the kits is run off. This kit requires a soldering iron and solder, and may require wire cutters.

How easy is this kit to solder?
This is a great kit for those looking improve their sound system and those just starting to learn about what electronics can do. Once you’ve put the kit together, you may want to add an enclosure (not included) to protect your circuit or add an input and output jack to make it easy to connect to. This kit can run off a 3-25V power supply (not included).

Is this product suitable to drive the speaker under prod no.L67AW? Is the 10k pot in the kit log or lin?

Asked by: chris
No, this is a pre-amp used to change line level of mics before a amplifier, which would then drive the speaker.

Other than probably requiring solder and iron, what components can you suggest I order to connect a suitable battery to this unit. Also, which type of battery would be best. Thanks
