Review on πŸ”Š KooBook 1-Piece NE5532 Op Amp HiFi Preamplifier Signal Amplification Board - Bluetooth Pre-amp, DC 12V-35V by Keith Baker

Revainrating 4 out of 5

Improves the performance of the microphone, but nothing with a dead head is used.

I tried it as a preamp for the microphone included in my citizen base station. It didn't amplify the deadhead mic, so I hooked up an active mic to it. Then a little magic happened. This gave the power microphone more power and hi-fi sound. I get compliments for AM and SSB. Also prepare some ferrite beads for the line to the radio. Rudedog 255 West Georgia.

Pros
  • With the NE5532 operational amplifier as its core, it consists of high-quality capacitors and high-precision metal film resistors with five color rings.
Cons
  • Reliability

Enhances a power mic but nothing used with a dead head.
