Works better than I expected
Since this product is advertised for solving noise in automobiles, I wasn't sure it would work for me, in a Church. I needed to connect audio from a DVD player and also a Satellite Receiver into unbalanced line level inputs on an amplifier. Directly connecting them with RCA cables was inducing a hum in the amplifier. I installed the SN-1, and immediately the noise went away. I have since used another one of these with a similar result.
At another Church, RCA ports had been installed at the back of the building. A shielded coax cable was used to run the audio nearly 200 feet to the amplifier, and there was a definite hum being input, with nothing plugged into the RCA ports. The SN1 did not solve that problem, although surprisingly to me, it did reduce the hum a bit. It is not designed to solve cable runs which are just too long.
But it works perfectly to eliminate hum between electronic devices and an amplifier. Even in buildings, and not just cars.
