Review: Works, highly recommended. - This is one of the ferrite devices that actually works. Recommended. Eliminated hum on my professional Sub with RCA to XLR cables.
Review: Worked perfectly for alternator whine - I installed a subwoofer, door speakers and 2 amps in my truck. I also installed a cheap 10.1" android head unit. It sounded pretty good, but had terrible alternator whine. It made it so the system was unlistenable at low volume. I did the normal troubleshooting of checking my grounds, making sure the RCA didn't cross paths with any power wires, used a nice shielded RCA cable, nothing would get rid of that awful whine. I didn't have high hopes for this $10 filter, but figured it was cheap enough to give it a try. It worked flawlessly. The amp is now playing crystal clear with no hiss, whine or anything. Just a nice dead silent noise floor. No noticable impact on output or sound quality. Note, as another reviewer pointed out, the label seems to be backwards. The male RCAs plug into the amp and the RCA cable coming from the head unit plug into the female end. Installed in less than a minute and solved my problem 100%.

## Questions & Answers

**Q: Is this unit self grounded?**
A: This device is designed to break a ground loop when it occurs over the “signal ground” of a signal wire. The shielding from the male end of the cable is not connected to the shielding of the female end of the cable. It will only help if your buzzing was due to a ground loop over an unbalanced signal wire.

**Q: Would this cancel the noise of engine on the speakers?**
A: Got noise coming from your alternator or engine noise. Try a capacitor on your alternator output tied to your power line to ground. Here are some links for a capacitor and info to go with it.

**Q: como se instala?**
A: I installed mine right next to the amp in the back floorboard of my truck. Isolator has 2 RCAs one each to your deck and amp. I installed mine backwards from the labeling because inputs to amp are female and RCAs from deck are male. Works great.

**Q: Could I use it to convert an unbalanced 600 ohm line level load to a balanced load?**
A: No.  This is not that kind of transformer.  You would need something like this: https://www.amazon.com/rolls-DB24-Stereo-Direct-Interface/dp/B001032GK8/

*by J***K on October 28, 2025*

If you’re planning to get this for car audio, DONT. It caused my subs to lose significant power. At least 50 percent of my bass. Also caused my radio treble to slowly fade out after about 10 minutes of driving, every single time. Radio would read, “check wiring”. Took this thing out and gained all my bass back and no longer fading out. If you’re having issues, it’s likely your power, ground, and RCA cables are too close to each other. Do yourself a favor and take the time to reroute them instead of wasting money on this.
