PAC SNI 135 Ground Loop Isolator Review

This product saved me! I bought a Belkin Bluetooth music/speakerphone that connected to my car's 12 volt power supply and my stereo's AUX input, and it made a horrible squeak that matched my RPMs. The higher the RPM, the higher the tone of the hum. This product completely eliminated that noise and made my new product usable. It removes the faulty soil found on my old machine. Must have if you have signal noise! The product and cables appear to be pretty solid. Easy to use.</p>

The claim that this filter has near perfect frequency response at 20Hz is a complete lie. After testing it firsthand, I could immediately tell that something was wrong with my music as soon as I plugged it in. As soon as I played a song with a significant amount of bass, I could find that the bass was completely gone; What was once a booming and resonant drumbeat has become flat and featureless. I gave it 2 stars because it really blocks out all the unwanted noise. but only at the expense of…

We recently decided to buy car charger cables for our iPhones and noticed a buzzing noise when connecting the charger and extra audio cables. Familiar with the concept of ground loops causing noise, I looked for an isolator and found this one. The picture showed that I would need an extra 3.5mm stereo cable for each machine and I was happy to see that I didn't need it as it comes with a jack and a plug, each on short cords, going into the device. It works out. very good at removing the hum from

I've been using the Zune in my car for about 2 years now (hey, don't beat the $80 30GB Zune from WOOT). I've tried several car chargers and regardless of the charger, I had significant static electricity when the Zune was charging. This little beauty eliminates almost all static charges. More specifically, on my stereo, 20 is the normal volume for listening to a song at a normal volume. Noise started to get annoying at about 15. Now, even with exceptionally quiet music, the volume can climb to…

I bought this product to isolate the noise generated by the headphone jack on my work PC. Unfortunately, the PAC was found to be unsuitable for this application. Other listings for the same product typically say "for 3.5mm applications", while this listing specifically says "between your receiver's AUX input and your portable music player". I can confirm that the latter is correct and that it doesn't work with headphones. Headphones and audio device, PAC eliminates unwanted noise. However, I…

My situation: I have a ground loop problem caused by something internal in my new PC (Asus) that I don't understand and will not understand. Problem: USB ports are noisy, analog ports are noisy; Front, back, all other hardware disabled including keyboard and mouse. All of the equipment's power cords are connected to a very expensive sine wave UPS which is plugged into a single wall outlet that has been found to be OK (polarity and grounding). The problem is computer endemic, I can't reproduce…
