Mindsets Low-Noise Stereo Pre-amplified Kit
• Boost weak stereo sound from your audio devices
• Amplify two channels to improve sound or output to an amplifier
• Fun to solder with 22 parts
• Requires a 3-25V power supply (not included)What can I do with this kit?
Use this kit to boost your stereo audio devices output to an amplifier or increase the sound. Amplify two channels with individual adjustable output levels – great for level matching. The stereo pre-amp uses the NE5532 chip, which is high output, low noise amplifier. With a compact 49mm x 35mm circuit board, you can fit this kit in almost anything. This is a great kit for those looking to improve their soldering skills, and comes with 22 parts. What can I learn from this kit?
Practise soldering and learn about electronics and circuits in a practical way. The kit uses resistors, capacitors, potentiometers and a microchip to create a circuit that amplifies two audio inputs – strengthening the signal without altering the pattern. The two potentiometers allow you to independently change the gain on each channel, letting you match the level on the inputs. The audio output will be dependent on the incoming signal, the adjustable level and the power supply connected. This kit requires a soldering iron
and solder, and may require wire cutters. How easy is this kit to solder?
This kit is simple to solder and ideal for those looking to move on from beginners kits. Once you’ve put the kit together you could add to your project with additional gear and build an enclosure to protect your circuit, or add jacks or screw terminals for easy attachment and detachment from the board. This kit required a DC 3-25V power supply (not included).
