4-channel Audio Isolator/RCA Noise Filter/Hum Eliminator

Applications
Ensure safe transmission between systems and protect equipment from being burned out by ground voltage differences.
Eliminate the current noise interference generated when connecting a car audio system/server projection/LED to a mixer.
Improve the sound quality by removing glitches and digital artifacts, and purify the sound.
Eliminate the current noise caused by impedance mismatch between devices.
Eliminate the current noise between simultaneous interpretation equipment and the mixer.
