Gold Coating RCA+Cable (Red+White) Make It Real HIFI Stereo
RCA Ground Loop Isolator Hum Eliminator
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).
Because the power supply is not on the same phase line, there will be problems in such a power consumption system: at least, there will be a loud current sound from the speaker while it’s working, and at worst, there will be sparks when the signal cable is plugged in.

We had an issue with a serious ground loop coming from our new computer to our sound system. This completely eliminated the issue.
Exactly what you’d expect

I have real bad static when no music is playing in my truck. I got this to stop that but didn’t make not a single difference once so ever and I’m not stupid I know how to hook it up . Not worth it

Worked great !Have (2) REL Subs hooked up to a Denon AVR thru the LFE Outs and just couldn’t get rid of the hum.This little box instantly solved the problem.Looks and feels well built !Totally Recommend ðŸ‘

I've never had one of these noise isolators grounded isolators noise removers function properly anyways so I was no surprise when this one didn't do anything for me maybe will you but

I'm an audiophile. I own an older Jeep Wrangler and it's outfitted with a ton of audio gear. I have amplifiers, a subwoofer, drivers in custom pods, a LiFePO4 bank, just all sorts of toys. I recently installed a tablet in my Jeep for passengers to watch movies. It works great for the most part, but I get a lot of hum/noise when it's plugged in. The grounds and connections are excellent, and the cable is fine, so I'm not sure why there's noise. I was looking for a solution, and when I saw this I had to try it.This is a neat little device! You do lose some audio quality when you use a noise blocker as it is removing some data from the song, but the reduction in noise is well worth it. I'm an audiophile, but given that this is being used for a tablet that's playing TV shows and movies I'm not nearly as concerned with keeping the audio pure. I just want it enjoyable.Overall I'm very happy with this noise blocker. It does lower the audio quality a tad, but very little overall. It removes the horrible hiss/hum I had, so now my media setup is enjoyable.
Euphoric!

I tried to give this thing the best possible chance at success, including much better quality RCA cables. I wanted to use this with my desktop's sound system, which has always had such an annoying buzzing sound. As a result, I was forced to use me speakers' USB unput instead, but that severely hampers output from 100 watts down to something closer to half that, if not less. So, the point was to use this thing to get rid of the electrical interference so I could properly blast my audiophile-level sound system.Welp... it did absolutely nothing to resolve the issue. Maybe I got a defective one? Who knows... But after multiple attempts, with various cords... this thing seems to do absolutely nothing.

The WisWinDa noise isolator RCA pro is "brilliant" for my hubby's audio setup. The unit is plugged in immediately before the speakers in the trunk so any of the extra “noise†coming from the head unit or the insulated RCA gets eliminated. He said there is a noticeable difference in sound quality.
