cman102030 Posted September 3, 2010 Share Posted September 3, 2010 I notice that on some records that I play, the sound quality tends to worsen as the needle gets closer to the middle of the record...anyone know what the deal with that is?

tankerdesk Posted September 3, 2010 Share Posted September 3, 2010 has to do with your cartridge alignment. Quote Link to comment Share on other sites More sharing options...
thrillho Posted September 3, 2010 Share Posted September 3, 2010 has to do with your cartridge alignment. this. and sound generally degrades a little towards the inside of a record. that can't be helped. Quote Link to comment Share on other sites More sharing options...
Vinyl Fury Posted September 3, 2010 Share Posted September 3, 2010 i think it really comes to down to physics. the closer you get to the center, the shorter the groove revolution is, and the harder it is for the stylus to properly track in the information. this is why i don't really like listening to 7 inch records. it can be worse if you have an automatic return function on your table. if the auto return switch isn't setup properly, it could start to trigger before the end of the record, causing a little more friction and distortion. i had this problem, and after having it tweaked by my local service shop (a very simple adjustment) there was definitely an improvement. of course, a misaligned cartridge can give you a number of playback issues, including distortion. always make sure your cartridge is properly aligned. if you don't know how, take it to someone who does. if you search google, you will find tons of discussions about this and other caveats of the vinyl world by some real audio nerds.

Dillhole Posted September 3, 2010 Share Posted September 3, 2010 It's just the nature of the vinyl record. If your cartridge is aligned properly it should hardly be noticeable. Also some carts/styli help reduce inner groove distortion as well. Sometimes if a record is played a lot on low end equipment or misaligned carts for a extended period of time the record can develop inner groove damage which gives the same sound as inner groove distortion, but damage can't be fixed by aligning a cart, the damage is done. I would first align the cart and see if that cuts down on it. Just imagine the edge of the record has the same amount of information as the center, but in the center each rotation is much shorter so the information is closer together which some carts have a hard time dealing with. Like "danfury" said this is also why I don't like playing 7" records as well. Quote Link to comment Share on other sites More sharing options...
