WisWinDa 4 Channels RCA Ground Loop Noise Isolator with Gold Coating Cable Red+White

WisWinDa RCA groud loop noise isolator is a portable design and “plug&play” direct box device.

The sound source and the input terminal of the isolator form a loop separately, and the output terminal of the isolator and the load also form a loop. There is no physical electrical connection between the front and rear audio equipment, thereby ensuring electrical isolation and achieving the following purpose:

1. Purify the audio signal transmission, utilising the unbalanced signal transmission mode, which could be sure that the signal will not have interference noise caused by the length of the cable;

2. Eliminate the interference noise caused by out-of-phase power supply;

3. Eliminate the interference noise generated by the ground potential difference;

4. Unplugging and plugging signal cables in accidents or emergencies will not cause sparks due to voltage differences, which protects the safety of the front and rear equipment; the power line is divided into A, B, C three-phase and the neutral line L. The general equipment is a single-phase power supply with a working voltage of 110-240V, using L, N, G (safety ground) three-wire safety sockets. In actual working situation, the distance between the sound source and the power amplifier and the simultaneous interpretation host is very far in many cases, and there will be different power supply situations: cross-phase lines, and different safety grounds (G).
