good for the price

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. ..

this works

I've always used these noise filters if I'm getting distorted noises and they have always worked. Once the noise is coming from the RCA wires, this product will eliminate it. If its a power noise, it won't. They have a different one for the power noise and pop noise.

It's a great product... if you can get to the needed place...

I've had it for several months now. This item is great for slightly older (pre-2007) G35 owners that want to be able to hook up Auxiliary input. However, it is only if you know how to take apart the stereo and get access to the cables and such behind it.

Once you are done, it's great! Never really had problem with it.

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

Great product

Does exactly what it's supposed to do, plugged it in and and the buzzing/ticking sound went completely away!

Absolutely works

I bought several of these to break the ground loops between a computer, a DVD player and a sound board at our church. Was easy to install and took the 60 Hz hum out of the sound system completely. Next will be trying one between the sound system and an HD Video Recorder. The company was quick to ship the products, also.

I bought it for my Tahoe and ended up using it everywhere in my sound and home theater, great product and value.

Works Great

I noticed a significant reduction in alternatory noise and whine. The head phones the kids use no longer have irritating back ground noise. Works as described.

Kind of worked

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.

PAC SNI-1 Quieted Computer to Sound Mixer

This little device FIXED a long standing problem in our church's soundroom.

Several devices were tried between the computer and Sound Mixer, but always with some audio hash and hum noise. The SNI-1 connected between the computer and Mixer resulted in the computer noise going down to the residual noise floor in the mixer.

I LOVE this thing! And another side effect is that the video feed is quieter also.

NOTE: I assume the durability of this will be good, but I've only had this for two days.
