Numark TTUSB Turntable with USB Get it now!


I am adding to the folks commenting on the HUM generated by this unit. Having many turntables since the 70's and not doing DJ gigs anymore I sold my 1200s a while back and decided to take advantage of the new units with phono preamps and USB outs - exciting....not so fast. Decided on this unit as it had pitch controll and was mid $ range, so picked this unit up last December when it was reduced to 150 bucks along with an excellent Grado labs DJ series cartridge and stylus, set the system up correctly and was immediately shocked at extreme buzz and hum. Tried tons of fixes in the last months, electicians to check my electical, adding an expensive power supply conditioner and every permutation of hookup of the unit but was still unlistenable. I was concerned the day I set it up that there was no grounding wire, which is universal for turntables, the plug had no grounding post - only polarized, which is NOT a substitute for an earth ground. Assumed that tech had come up with some way to ground out the unit in the preamp phase...sadly no.

So back to more trick-fixes, and did find something that calmed the buzz and some of the hum...turning every electrical thing off in the room. The television was the worst, even though on a seperate circuit AND located almost 10 feet from the turntable! BUT even with everything off there is still the hum, WHICH gets incrementally louder as the tonearm tracks closer to the center of the platter! This is all so strange to me and irritating, so the unit is playable only over speakers - if you have headphones on it sounds horrible. And to record such awful quality to digital format...forget it.

Actually got this unit from a dealer (turntable lab), and 3 times going to different staff there each person immediately told me that the problem is the ground. When I told them the unit has no ground they all looked confused and told me to contact Numark, 3 emails to their support have all gone ignored. Ready to take a hammer to this thing. So if you are looking to burn your vinyl to an ipod that will play on headphones - beware - nails on chalkboard. You may luck out and have a setup that allows you to minimize the hum, but I doubt it would ever disappear enough to sound even halfway decent.Get more detail about Numark TTUSB Turntable with USB.
