Acoustic Revive Vibration Dampening Plugs for Output Terminals Unused analog and digital input terminals on audio equipment act as antennas, attracting noise. This noise can destabilize the equipment's circuitry, leading to significant sound quality degradation. By attaching shorting pins or plugs to these unused input terminals, noise intrusion is prevented, stabilizing the equipment's operation and dramatically improving sound quality, including improved S/N ratio, soundstage imaging, and reduced distortion and muddiness. Furthermore, the superior vibration damping structure of brass + 2017S aircraft-grade aluminum alloy + special damping material reinforces and damps the equipment's terminal board, further enhancing sound quality. Unlike other shorting pins or protective caps, these do not introduce any characteristic coloration or unwanted artifacts. These vibration damping plugs are for unused RCA output terminals. Similar to the input terminal shorting pins, they utilize a hybrid structure of duralumin and brass, with a non-conductive material for the center pin, and natural quartz or a special damping material to provide outstanding vibration suppression.
