Hard to find unless online.
||Posted .Owned for 3 weeks when reviewed.This Noise Suppressor works. If you do not know how it works, because it lacks instructions, you may have to experiment to resolve your interference issue. Before the amp or after the receiver head, mmm that's the question. I installed this product in a 1978 Chevy Corvette with the main problem with engine noise. Let's see, 1978? The year of the Cat?

Fixed feedback buzz in PC to Stereo Connection
||Posted .Great little device. before tearing your computer down to see where it's not grounded properly (because it probably is) do s simple check. Are your Stereo and your PC on the same power circuit? If yes you might get that annoying 50Hz to 60Hz buzz from your speakers. This fixes the issue because it was designed to do so. It isolates and traps the ground loop feedback and - magically - no more buzz. It's a 2 minute fix that the stereo folks have know about for decades (because it's an analog issue not a digital one). If you have it though the audio inputs it's easy. They make ones for 1/8in plugs as well but this one fit my need perfectly.

Great product
||Posted .Owned for less than 1 week when reviewed.So this is a product that works great depending how you use it for light noise this should work fine with out grounding it how ever in my case it was just ridiculous noise but, after grounding it to the cars chassis all noise is gone , its easy to ground just tie the two wires hanging from the box together locate a ground wire usually black!! And tap into it tap don't cut!! Meaning splice to get some wire to connect the box too and boom grounded and all noise gone ! :)

good product
||Posted .Owned for 1 month when reviewed.The product does what it says. No instructions but if your buying one you probably know whats going on. Cant say much about it, however the audio techs you have at the Boynton Beach congress are awsome. They know who they are. Very knowledgeable went above and beyond to help me do a custom audio job as far as whats needed ,doing the research looking for every possible options. So to the i give 5 stars

Car Amp and Sub Installed to TV.
||Posted .Owned for less than 1 week when reviewed.Hard to fine, literally called a store that specializes in DIY (do it yourself) fixing technology and they had no idea what I was talking about and told me to check Home Depot. I needed this because of a "Hmmm" noise coming from a car sub woofer I installed in my home. The aux from this device is connected to my television, while the output is going to the cars audio amplifier. The ground wires from this device is also connected to the amplifier in the ground terminal. Problem fixed!

Q: QuestionHeard these take away from your sound
Asked by Chozen.
- A:Answer Actually a ground loop audio isolator enhances sound quality by eliminating AC hum. Ground loop problems are caused by small voltage differences that normally exist between the ‘grounds’ at the send and receive ends of a audio signal cable. In an unbalanced interface (consumer audio), this ground voltage difference directly adds to the signal. This generally produces hum or buzz in audio. In a balanced interface (professional audio), the ground voltage difference may reveal inadequate common-mode rejection at the input stage of the equipment (Bad Ground ) or other design defects. A ground isolator in the signal path is the fundamentally correct way to eliminate system ground loop problems. A transformer does this by magnetically coupling the signal across an electrically insulated barrier wh9ich blocks electrical noise and creates a clean audio signal between pre-amp and amplifier and is connected as depicted in photo.

Q: QuestionWhy does this devise kill 70% of my bass?
Asked by Mike.
- A:Answer I think the transformer does not provide a flat frequency response down to the 20-50 hz or lower range. You could try to flatten the curve with bass boost. It may be that a higher quality/price isolator would provide a flatter response on the bass end, but i haven't tested this hypothesis yet.

Q: QuestionDoes this device need power? I can't see the specs to see the power voltage and how to connect.
Asked by Jeff.
- A:Answer No power connection. Connect RCAs to unit and unit to amp and than connect connection from unit to ground and done.

Q: QuestionWhy wouldn’t this work on a home audio system?
Asked by Jake.
- A:Answer I’m not sure why. I just hooked it up between two of my audio components with the problematic component placed after the ground loop isolator and it cleared up the buzzing sound.
Answered by Gump52
Q: QuestionDo I need three of these? One for the subwoofer connection, one for the channel one and two connection,one for the channel 3 and 4 connection. I have a 5 channel amp. Thanks
Asked by Ed.
- A:Answer Short answer: No. The ground loop isolator is designed to connect line level outputs to inputs...for example from a CD player line level output to an amplifier line level input, both of which would have plug-in (115 volt AC) power supplies. The amplifier output to speakers would not benefit from an isolator unless the speaker is powered and plugged into a 115 V outlet. So if the speakers are passive and powered by your 5 channel amp, the isolator is not needed. Moreover, if you are feeding signal into the amplifier from a battery powered MP3 player (or similar device) the isolator is not needed. It is only helpful when connecting two devices that each have plug-in 115 V AC power supplies. Finally you may find that the isolator attenuates the bass end of the audio signal, so if you are not pestered by a 60 hz hum, don't use the isolator.

Q: QuestionDo you need to hook up the ground wires? Or doesn’t the ground wires make a difference?
Asked by Mikey35.
- A:Answer Did not hookup my ground wire and it still worked just fine no more winding sound.
Answered by 1989
Q: QuestionAm I able to ground off the brown wires to the same spot as I grounded my amp? I grounded off both brown wires to the same spot as I grounded my amp and the ground loop noise somehow got worse! Can the brown wires be grounded on the same spot?
Asked by zak.
- A:Answer Don’t ground the brown wires - tape off.
Answered by Dano
Q: QuestionOK - I bought this and it has 2 brown wires. Som people say ground them to the car. Some people say ground them to the amp. Others say tape them off. 2 questions: Why 2 identical wires? What is their purpose?
Asked by JimmyJalapolington.
- A:Answer It's one ground per rca channel
