when i crank the volume on my system (only a philips home stereo system, mind you) i start to get a "hum" from some records. the one way i have found to correct this is to turn the bass down.

this happens with some records, but others still sound crystal clear.

what could be causing the records to hum like that?



"when i crank the volume on my system" also, when its at lower volume, i dont notice this at all.

it's feedback
the needles are picking up the bass vibrations

that's why it goes away when you turn the bass down

where do you have your speakers?

i figured so...just checking.

my subwoofer on the floor(with carpeting. it would make a difference vs. a hardwood floor) about 3.5 feet from my table that my dex are on. the table im using is a folding table.

my other speakers are sitting about 5.5 ft. in the air because they are on top of this shelf-y thingy thats part of my desk.

Maybe you need turntables with a heavier base. I'm still in the process of upgrading from old Numark belt drives and I currently have one of those belt drives and a Stanton Str8-80. My Stanton is a fucking tank compared to the belt drive which feels like it weighs between 5-10 lbs (for real). The old one hums like a bitch with the volume cranked to ear piercing levels while the Stanton doesn't. It's because of the heavy base....it absorbs vibration, so that's something to take into consideration.

Regarding the bass problem, someone else posted in here a crafty lil way of making ur own 'bass suspension' or whatever its called - sorry, not a pro DJ so i aint down with all the lingo, eheheh.

Basically get 4 of the same food can, or any can. Rip off the top and take out all of the goods inside. Clean em out, then get 8 strong elastic bands (2 for each can). Wrap them around the can so there's a length of the elastic band over the centre of the open end, place it in the middle, then get the other elastic band and do the same so the band crosses the first one at a right angle. Basically so you make an X over the hole of the can. Do this to the other 3 cans then place the feet of ur turntable on each one, and there you go, it hovers over the air getting rid of the bass vibrations.

i get heavy ass bass feedback when i touch one of my needles.
i got that particular needle from my couzin from germany.
he sent it over here to aus.

could be a screwed needle. but as soon as i touch it it humms..
the other one doesnt do that..

Yep and if you don't clean it out properly you've always got baked beans or creamed corn on hand for one of those marathon 13 hour mixathons

Make sure both your turntables are properly earthed if not this causes hum as well.

You know there is an ENTIRE MARKET of Audiophile paraphenelia (sp) that does nothing more than reduce unwanted vibrations with turntables? Why dont you all check out some of those tweaks and such? Pick up a copy of Stereophile, ignore the crazy $50,000/pair speaker reviews, and look at the advertisements for turntable stuff..

well, problem solved

what i did was flip the 180* switch on my subwoofer. it reversed the direction the subwoofer was firing, so now there's MUCH less bass feedback.

i still have a problem with my needle humming when i touch it...
i suspect it may be screwed as the needle itself is used and has travelled from overseas...
