Hey all, I too have been very impressed with the Numark TT2s, but have also got the pitch glitches. I mailed Numark about this, and got an instant reply that they needed servicing. That was where the problems started, I mailed someone at Numark US HQ to find how to get them serviced ,and was told that they would have to contact someone for me as I live in the UK. I had to keep chasing up, and it wasn't until TWO AND A HALF months later that they finally got back to me with the UK servicing phone number. I gave them a call and they advised me that this was a very rare problem, and it was probably a Mobile phone causing the probs. I have since put my decks on a surge protected extension lead, and have relocated them about 4 times but still have the same probs. Now I have this info as backup I'l give them another call to get it sorted.
I would advise any one who is impressed by the TT2 features to get a pair, but be prepared for poor after-sales help by Numark themselves. Perhaps they should get this investigated and start testing the decks before they send them out for the public, or at least acknowledge that this is a known problem
