Hello everyone, I'm brand new to these forums and I just want to say that I'm just delving into the world of vinyl and I'm really excited to be doing so. I just purchased an Audio-Technica AT-LP120-USB.
Last night I headed down to my local record store and purchased my first few albums. I set everything up, and have been playing albums to my Sony AVR successfully for a few hours with the phono pre-amp engaged. The problem was that I have a low frequency "thumping" that was really prevalent. It kind of rumbled at about eight times a second, really really low. It was present with the turntable powered on, even without drive engaged. I did some research and couldn't figure out anything that would nail it down or fix it. Finally, I put my hand behind the audio wires to see if there was anything wrong (the wires on the LP120 are permanently attached), and the sound went away. When I removed my hand from the back area, the sound came back. I turned everything off, tilted the table back to see if anything was wrong or out of place, and couldn't find anything. When I turned everything back on, the sound was completely gone. I can't reproduce it. Now of course I'm thrilled the sound is gone, but I'm the type of person that likes to understand the internals of things, so I'm wondering if my description helps anyone think of what could have been the cause. If it comes back, I want to know what's going on. Thanks everyone for your help! I look forward to hanging out on these forums for a while.
Thanks! I'll keep researching
