Amplify the signal from a wide range of microphones to a level capable of driving any line input. Can be used with dynamic and condenser microphone with an internal supply plus 3-pole condenser microphones. There are two inputs with different sensitivities.Features
The circuit uses an LM833 IC that ensures low noise, low distortion, high sound quality and reliability. The gain can be adjusted by a trimmer to avoid overloading and distortion.
Kit includes all board mounted components and solder for assembly.Specifications
