E.uPh due to the ripple detection of the DC bus. This is typically caused by a missing phase on the input side of the inverter.
Measure your mains voltage L1-L2, L2-L3, L1-L3 and L1-ground, L2-ground, L3-ground to verify that your supply voltage is balanced and withing the rated specifications.
If the applied voltage is good then there is a problem with the input stage or the DC bus and the unit will need to be repaired or replaced.
It almost certainly has a #2MT (#2 Morse Taper) drill adapter. Lower the quill and look for a slot on each side of the quill - that's a knockout slot. Insert a steel wedge into the slot and tap the wedge to force the Morse taper apart.
You can buy replacement Morse taper chucks from any number of woodworking or woodturning supply places, or from metalworking supply places, or eBay. You can get them from Grizzly, Packard, Rockler, Enco, Victor, MSC, Grainger... you can buy them through Amazon, you can get them at Sears.
You can buy the assembly as one unit or as two pieces - the chuck and the adapter. If you buy it as two pieces, be sure that the adapter and the chuck have matching tapers - that's usually a Jacobs taper like a #3JT or a #34JT, for example. It's much easier if you buy one matched unit.
You can get keyed chucks, keyless chucks, and automatic chucks with a #2MT shank.
It's not really a digital signal, per say. Its an analog representation of a digital signal. This is good because it's easier troubleshoot. The first thing I would try is check the ground wires. #1cause of Serato Traktor problems. If that's not it, play an analog record to see how it sounds. If you have a missing channel, clean the cartridge with a pencil eraser and inspect the stylus and try again. Restart your mixer and computer (this cycles the ground) and you should be good to go.
If not you may have bad cables that will have to be changed. See the thing about turntables is the audio signal never comes in contact with the turntables electronics. it goes from the needle through the arm and out the cables. The cartridge's signal is magnetic not line level so it needs good shielded cables. Perfect opportunity to upgrade the cheap cables from the manufacturer and you can internally ground the turntable at the same time Eliminate the annoying ground wire. It requires a bit of soldering, all amateur stuff. Youtube is filled with tutorials on changing cables and eliminating the ground wire. oh make sure you have a good shielded USB cable.
If this doesn't work I can think of more.

Hi, Yes your turntable needs to be grounded to get rid of hum. Make sure that your turntable, preamp and amp are all powered from the same point. Most preamps do not have a grounding connection on them and when they do it is normally on the same side that the rcas from your turntable connect too. What is the make and model of your preamp. I will check it out. To earth to a preamp without a grounding connection do this. Take the grounding cable from your TT and slip it in the side of one of the 2 rca connections as you plug them in. That will ground your TT to the amp. If it doesn't then swap the ground lead to the other rca. Cheers John. Styluscity.com.
either the cartridge is bad in the phonograph tone arm. Or the pre-amp in the stereo is bad...remember that the turntable is the only accessory that uses the pre-amp input on the stereo. I'm betting the pre-amp is bad.
You will more than likely need to wire it up from the inside of the unit, unfortunately. Parts for this model are discontinued. You can also try an iPod cable. As the size is a 1/8" plug - same as an iPod cable, then just cut the other end, and ground to your receiver.
