Adapter makes loud humming noise when plugged into either the wall or power strip.

When I first bought it there was a weird noise it would produce but as soon as I grounded my turntable to it that went away

Now all I get is a loud humming noise out of the right channel.

Sounds great--no noise

Then the left channel began to output excessive static/rumbling noise that increased from intermittent to eventually continuous.

The preamp made a humming noise when it was plugged into our turntable.

The Pyle-Pro gave me the quality I expected, however if the Pyle approached my Denon one and a very strong noise occurs inrferencia

No hum or audible noise as well

this convenient little box seemed perfect, but it sufferes from horrible ground loop noise, even with the ground cable hooked up.

I don't hear any hums or other unwanted noise.

The noise only cheats up if I unplug the left channel,Caution on this one: you'll get what you pay for!

So far, it is what it says it is, the exception being a ground feature that adds static noise to the signal

Unacceptable high noise

It lights up but does nothing except pass through very fuzzy noise.

It's surprisingly musical, with an inaudible noise floor.

It made a horrible buzzing noise.

When I tried using the ground screw on the preamp, the turntable made a humming noise

Left channel has horrible white noise

Enter the Pyle-Pro PP444, a compact, noise-free box that does the trick

no noise on my humble vinyl setup, sounds just as good to me as when using other receivers with onboard Phono input

But I have to keep it unplugged when I'm not using it or it causes odd static noises through my speakers, even when the turntable isn't hooked up to the pre-amp

Pyle o crap

Good I/O options.
