what decks are they?

does anything else play up at the same time? (lights dimming etc)

do you know what sort of mains power feed do you have to your house? are there thinks like electric ovens or showers?

yeah it realy depends on what decks you have … if there belt drive .. then well .. um … you got riped off imo .. unless you got them for -£10
if not then the torque on the motor might be some thing to do with it … is it a problem thats just started to happen or are they new?

well i use vestax pdx2000’s and have had that problem some times … i think the vertion of newmarks you have are based on them … i was told by m8s that vestax have all soughts of problems if not regulary servised .. ranging from them varying rpm to spinning backwards out of the blue… iirc your decks have a reverse button on them .. and other digital shit like that … the problem with vestax is as far as i know the complex electronics of the thing… so you get a slightly off tuned bit of electronics or it gets a knock or summing like that that puts it out of synk shit like that happens … i meen there are the other things to think about like running shit loads of plugs off a divider .. that dont help for sure … but who don’t do that …. another friend of mine told me about his vestax that he gets regulary checked every year for £50 and that keeps the garantee for another year also … he never has had any problems with his .. and all my other m8s have at some point had a problem of some motor speed related shizzle with there decks ..regardless of make brand … even the non vestax designs witch are renowned for that kind of shit … well vestax them selves n e way … so all tho it could well be summing to do with your set up ie. to many plugs… if you can aford it it might be a good idear getting some one to look at them … that only if you have eliminated every thing else ofc 😉

yeah tbh it could be caused by a few things mentioned by peeps in your thread .. just eliminate them acording to ease first and then think about re wireing your house or getiing new decks .. or even getiing the nemark ppl to charge you more than the decks them selves to fix them …asuming numark is like vestax xD .. you know they vestax sell the dust covers for pdx2000’s for £50 each seperate from the decks … hahhaha i know there good ..but cummon there not that good :crazy_diz

numarks have flimsy cases

electrical fields will effect them so move the amps, lamps and anything else as far away as possible

yeah thats a good idea … i notice that if i got a fucking bundal of wires some where pluged in it will will make shit humm from the coils of wire out my speakers .. so if thats near your decks then it might make the motor fuck up as that works on ac witch is esentualy what a mess of wires will make ..(half an ac motor) so yeah if you got shit like that either move it away or pref organize it some ..i banished messy wires in my room a while back lawl:sign0010:

You may also find that oiling your decks [check your manual for where] may help with that

and also if your decks arn’t on a level serfice then that may have some effect…

I seen a box used before (by a crew) and was told it was to stop the power fluctuations that cause turntables to slow and speed – but I dont know what it was called – 🙁 can only suggest maplins or call technics…

if you can borrow a turntable you can check whether its your numark decks or the power before you have to spend out…..

oh do you mean the isolation sockets? that stop power surges … there used for computors alot to stop them getting fried if theres a powere serge..?
