Question about Numark ttUSB Turntable
Just bought the TTUSB Numark turntable and I"m hearing a high beeping noise, like as if the ground isn't connected. But as far as I know that isn't nescessary. Does anyone know a solution to this problem?
SOURCE: Ion ttUSB turntable fault
The ION should be internally grounded, however, it's possible the Tonearm might be faulty as well. Try a different USB cable as well - make sure you have one rated for the type of USB card you have (1.1, 2,0, etc).
FYI, this isn't the most sophisticated unit on the market, and not very well made either, so you might just have a faulty unit. If it's relatively new, I suggest calling in for warranty info, or try and return/exchange it.

the mic is in the computer somewhere, there will be a way to mute the microphone either in the vinyl software or in the system settings of the computer!

SOURCE: im new with the use
A turntable use a magnetic cartridge and its output is only 5 to 10 millivolts.A moving coil cartridge is even lower,.2 to .5 millivolts(thats 1/2000 of a volt)in contrast, a mp3 puts out a 300 to 900 mv signal..so does a CD player. Your turntable does not have enough signal.You need to get an amplifier that has a phono input. Years ago,radio shack used to sell phono preamps that could plug into a tape or cd input.The other option is to buy a used mixer that has a phono input.The mixer output can drive the cd input easily,as the max output from a mixer is 1.5 volts to 2 volts.

Turntables require a special input in the amp (usually marked PHONO) because they require high gain and different equalization - and yes, that ground wire has to go to ground unless you want to get a super annoying 60Hz hum from it!
If your amp doesn't have a phono input, you're going to have to go out and get a phono pre-amp and connect it between the turntable and the amp.
Best of luck!
