I have first browsed the wiki for this, though only a few minutes. My question is about adjusting the tone arm on the Numark TTUSB. Can anybody tell me where there are instructions on adjusting the counterweight on the tone arm of the Numark TTUSB and adjusting the anti-skate mechanism?
I got the turntable yesterday. The instructions in the operator's manual is insufficient, with only a few sentences on the subject that seem very ambiguous to me.
The manual says,
...there should be a feeling of weight and resistance when the head shell is raised and lowered. Begin rotating the counterweight clockwise (away from the pivot point) until the weight and resistance feeling is gone. If done properly, the tone arm will pivot with very little resistance back and forth indicating that there is exactly 0 grams of stylus pressure. With the counterweight in its new position further away from tone arm pivot point, grasp the scale ring of the counter weight and rotate it until "0" is in the vertical position. Finally, rotate the counterweight (and scale ring) counter-clockwise (towards the pivot point) until the desired amount of weight is reached. If the scale rotates 360 degrees beyond the zero point, the new scale ring reading should be added to 3.5.
I don't understand these instructions at all. I remember seeing somewhere last month, when shopping for this, mention of some website or other with instructions on adjusting the tonearm and antiskate functions.
Thank you, in advance, for your attention on this subject.

The Knowzy website had a tool for sorting out turntables according to their features. I had chosen obviously to keep out DJ turntables, and believe that the Numark was listed after cutting out the DJ turntables.
There were a few errors with this turntable that I have since corrected.
My mistake was believing that the Numark TTUSB was the same as the Ion Audio TTUSB. It's not. Here is how they differ:
even that the cartridge on mine is called a "groove tool," had taken me by surprise.
To my surprise, I got the specs for the GrooveTool out of Numark today.
The specs don't read like a DJ cartridge as far as I can tell. They read like a $20 cartridge, which it is.
The big question in my mind what disadvantages the spherical tip has over the elliptical tips.
Here's the specs for the GrooveTool:
Channel Separation @1KHz
Channel Balance @1KHz
2.5 to 3.5grams,
47k ohms and 275pF,
Lifetime (under normal use)
I don't want to grind out the threads on my vinyls with this groove tool.
You don't need to worry about that, particularly if you're going to do a single pass through your album. Just set your tracking force near or at 3.5 grams.
Can anybody tell me of a a quality cartridge to replace the cartridge that is on my turntable?
For $55 you can pick up the Ortofon OM 5E. It's the same cartridge and stylus found in the best USB turntable- the $500 Pro-Ject Audio Debut III USB.
You'll save yourself a gram of tracking force. You'll get an elliptical tip. I expect it will sound noticeably better. But it's not going to turn a Numark TTUSB into a Pro-Ject turntable.
Don't forget, if you buy a new cartridge, you'll have to mount it and align it, which requires some skill. The cartridge the comes with the turntable is already mounted.
