## Description

desertcart.com: BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable : Electronics

Review: Works Perfect – Got Rid of Static Noise Instantly - I bought this noise loop isolator to fix the static/humming sound in my headset, and it actually worked right away. Before using it, I had constant static and buzzing, especially when connected to my PC. As soon as I plugged this in, the noise was gone. Audio sounds clean now with no interference. Super easy to set up — just plug it in and it works. No extra settings or software needed. Build quality feels solid for the price, and it’s small enough to not get in the way. If you’re dealing with annoying static or ground loop noise, this is definitely worth it. Fixed my problem instantly.
Review: Worked like MAGIC - I installed an iPod Nano (1G) dock in my truck 20+ years ago. I wired the dock directly to the cigarette lighter circuit (it was a 12V automotive dock. This worked fine with my Blaupunkt CD player, which had rear RCA inputs. I replaced that head unit with a cheapie Jensen Bluetooth deck, which has a front headphone jack. With this (much cheaper) head unit there was a high pitched dirty wail on the AUX input, which was very noticeable when the volume is turned up. This little noise isolator completely eliminated that noise. Gone. I was skeptical that this could even work, and then when reading the directions I also realized it was supposed to be hooked up opposite of my setup (male to stereo female to ipod). So I figured it wouldn't work well or at all. WRONG. The noise is completely gone, and now I don't have to pull the dash apart again to wire in a power filter. 100% recommend this, it saved me probably 3 hours of work in a hot car with no AC in the NC springtime. Highly recommend.

## Questions & Answers

**Q: Does this have the ability to also have the microphone pass through this device? I would like to use it with a microphone headset.**
A: Thanks for your inquiry, this ground loop noise isolator is not workable for the microphone.
Any further assistance, you could contact us via e-mail: bdesign-us@outlook.com.
Thanks.

**Q: can i use this on my raspberry pi arcade im runing sound thru audio to 5.1 pc spekers setup will this stop hiss on speakers?**
A: Depending on your setup, no. It will strip low-end signal entirely and affect the audio negatively: I tried on a PC 5.1 system (on the stereo pair 3.5mm main pair) and it stripped all the low-end frequencies.

**Q: Will this work with 250ohm headphones hooked up to a gloxlr mixer?**
A: Yes. you won't run the headphones into this though. You can find videos online on how to properly use but You'l want to connect this to your PC/ Go XLR depnding on the in/output causing the noise.

**Q: I have a Amplifier and a dsp like a eq but digital I get humming and buzzing noises where do I plug these in?????**
A: I’ve got mine plugged in to the aux on my car stereo, which is also the amp, so my best guess in your case would be to plug this into your amp, and then plug your DSP device into this noise isolator. Your may be different, course, as yours is a different setup, but you could always test it at the various connection points. It definitely works in my car, though.

### ⭐⭐⭐⭐⭐ How to get rid of the hum! Plus a pro-tip
*by C***C on April 12, 2024*

This thing does exactly what it says it does. The fat little section has an inductor that creates the magnetic field that makes sure when current (sound in this case) flows through it, it is normalized and doesn't have any potential difference (which causes the hum we all hate). It's cheap and works on the 3.5MM input that I plugged it into and no matter how much power I throw at it now, there is no more hum. A good buy and I recommend. Pro-tip: Where do I put this thing in the sequence? The age old question of before or after that amp??? Well, conventional wisdom usually says add this inline as close to the amp as possible between the head (stereo) and amp. In other words, put this on the input side of the amp. Stereo --> Isolator --> Amp --> Speakers. This works in the vast majority of cases. There are some instances where there might be components after the amp besides the speakers, perhaps some kind of Bluetooth adapter, or game console, or something. This situation is more rare but in that case you'd put an isolator after the amp (out put side) but as close to the speakers as possible so Stereo --> Amp --> Component X ---> Isolator --> Speakers. There is also a third scenario where you put an isolator before the amp AND after the amp but before the speakers because you are getting two kinds of issues like potential current differences from a bad ground on the stereo feeding into the amp (corrected with the input side isolator) and then a shielding problem on the way to the speakers or another component that is leaking on to the line with a bad ground or the like (corrected with the output side isolator closest to the speakers). Why not just add one single isolator as close to the speakers as possible to correct it all? I'm glad you asked. This is because unless you get super high quality and usually powered isolators, you can't expect miracles and the potential difference might get so high that one isolator just isn't enough to correct it all so you correct it one step at a time after each component that is causing an issue. Bottom-line: One isolator on the input side of the amp or right before the speakers is usually enough and this thing works great for that.
