Noise Filter Specifications

Noise Filter Type
This designates the type of noise filter listed.

Ground Loop Isolators are connected in-line with the RCA interconnects or other audio cables.

Power Line noise filters connect to the power line of the receiver and help reduce noise from the source.

Pop Eliminator noise filters are designed to remove the "pop" that occasionally happens in some systems when the vehicle is turned on.

Ground Loop Isolator
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.

great

March 7, 2011

Worked perfectly I also recommend taking a small wire and wrapping it around your rca outputs on the head unit and grounding it on the closest screw. it took away all noise from head unit static and the engine rpm

I had to hook up my equalizer the old school way due to the fact that I only had one set of pre out on my head unit (rca to speaker wire)... so that created a slight hum and kinda annoying. .. so I bought this Pac sni-1 and installed it and wow what a difference. . It took all the hum out and it was an easy installation. .. strongly recommend. ..

Worked but not great

October 31, 2013

The remote out would stay on for about a minute after car was off sometimes my amp would get interference and the sub would start going off with a loud bass note due to this unit.
It also has alternator whine noises. The instructions could be better they were not clear enough for me on the wiring of the black wire i guess for ground loop noise???? I replaced this with a cheaper xscorpion unit that is passive not active like this one and the alternator noise was reduces

Kind of worked

September 19, 2013

I have an issue with the RCA cables carrying the signal for my front channels. Both left and right channel had their own problem with noises on the amp. This device completely removed the noise from the left channel, but somehow made it worse on the right channel. So I have the left channel into this device and right channel directly into the amp.
It might be a hit or miss product, but for the price and with the return policy I recommend it.

Didn't really work

September 17, 2013

A lot of people said it worked but it didn't work for me. Ordered two and none of them worked. It just muffled the volume output and did nothing else. Didn't get rid of the alternator whine at all.

I used 2 of these in my car. I have 2 amplifiers powering a sub and 2 sets of component speakers. I was getting engine whine in my speakers. I hooked these up at the amplifiers and it killed the noise and did not effect the sound at all. These work great.

PROBLEM SOLVED!!!

February 21, 2013

GREAT ITEM, GREAT COST, WORKS GREAT. After I installed my kenwood 4 channel amp ran to my door speakers i acquired a whinning humming sound that went along with the tone of the motor. I installed a new head unit for different reasons and it seemed to had gotten worst. I looked for options and came upon this and after the 20 seconds it took me to hook it up my problem was gone! I love it, money well spent.

Doesn't Eliminate Engine Noise!!!

January 6, 2013

This product works great for what it is. It got rid of all the annoying wining from radio interference. But i was also under the impression that eliminates engine noise as well. it doesn't! It's not too big of a deal because the noise doesn't bother me. But if you're buying this for engine noise think again!

CHEAP MATERIALS

December 20, 2012

The RCA jack failed within 6 months. The male plug is actually a piece of plastic coated with metal. The THIN layer of metal (like foil) cracked and separated. I had to spend some time fishing out the metal from the female connector.. What a cheap piece of crap!

I've got this on both 4 channel amps and my three sub amps. What a difference it not only stops the high pitched wining it cleans up the entirety of the sound all together.

Works on ground loops

September 9, 2012

This inexpensive box does indeed cure the ground loop interference that plagues us musicians/audiophiles. If you can hear your computer's inner workings or your car's engine in your music as noises then you have a ground loop. Later, I moved on to the Hum-X for better fidelity since I mix and master music on my speakers, but an snl-1 will surely work for your listening pleasure at home or in your car.

PAC SNI-1

August 1, 2012

I purchased 3 PAC SNI-1 ground loops for my 2005 Corvette. One for front, one for rear, and one for subwoofer and hooked them up close to the amplifier. I was getting a lot of loud whine and they took 100% of the whine away. Great product at a very reasonable price. AND they WORK!
