Review on π Pyramid NS20: Advanced 15A RCA Noise Suppressor for Clean Audio Signals & Noise Elimination - Built-in Isolation Transformer, Ideal for Amplifiers & EQs, Easy Installation via RCA Jacks & Unique Noise Detection Circuit by Jesse Wells
Worked great with built in amplifier
Nobody was able to solve my car audio feedback problem. It wasn't a buzzing noise and it didn't respond to the accelerator pedal. Instead, it was a fast clicking sound at idle. Tried different amps. Tried different cinch cables. I've even tried attaching noise filter wire ring magnets to RCA cables. None of this worked. This product is the only thing that worked! Feedback sound is gone! The sound quality of my music was also unaffected. I am a very happy customer!
- Quality construction
- Requires power outlet
