MINI3 Microphone Preamp Dynamic Microphone Amplifier for SM58S Audio Interface Amplifier with 48V Phantom Power Supply 70dB Gain Adjustable

Principle of Tinseampa MINI 1/2/3 balanced amplifier circuit The mpa MINI 1/2/3 circuits all use fully balanced amplifier circuits, which are currently more advanced amplifier technology. The basic principle of the fully balanced amplifier circuit is exactly the same two amplifying circuits, one amplifies the positive phase signal and the other amplifies the inverted signal. After amplification, the subtractor circuit is used, and the positive phase signal is subtracted from the inverted signal. , The useful signal becomes twice as much as before the subtraction, and because the amplifying circuits are exactly the same, the noise, distortion, and interference they produce are exactly the same. Then when doing the subtraction, these noises, distortions, and interferences All canceled out. Therefore, the fully balanced circuit can significantly improve the performance index of the amplifier. Tinsea mpa MINI 1/2/3 uses a fully balanced amplifier circuit, so it has a higher performance index.
