Noise when playing vinyl

Guys, thank you again! Viridian, I placed felt pads under the heavy entertainment center that I have the TT on, and I also placed felt pads on the metal feet that my Totem speakers have. That has solved the problem! Which is a good thing, because I could not move the speakers to any other location. Thanks so much again!!!

You need to move and isolate your turntable away from your speakers.

Thank you all for your prompt replies! Here's what I've got so far:Zd542, the turntable does not have a built in preamp. When I connected it to a line level input, there was minimal sound with the volume turned up. Mattmiller, I don't know the model number of the tonearm, but it is the one that the turntable originally came with. I have an Ortofon Blue MM cartridge installed, and, aside from that occasional noise, it actually sounds pretty good. Viridian, I also did as you suggested and indeed the woofers shake and the noise returns as soon as I pass about the halfway point on the volume knob, so it is consistent with acoustic feedback. So, where do we go from here? Thank you all again for all the help!

Do you know if your TT has a built in phono preamp? If you are not sure, plug it into a line level input and see what it sounds like.

Its sounds to me like a major cartridge tonearm mismatch. Try a Cartridge that the tonearm likes. This is most likely why you are having so much woofer movement.
