Numark TTUSB tonearm adjustment Options

[rocket_pc]

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.

Hi all,

I aggree that this Numark is a lousy turntable, but that is because it has poor design and engineering. From my recollection, the Knowzy website shows that this turntable is for digital conversion, rather than for DJ. Why they had advertised a rebate for a free DJ cartridge for purchase of this turntable, I don't know, other than maybe they were trying to get rid of it.

This Numark is belt driven, whereas djs prefer direct drives. On some websites, belt driven is preferred by people recording the music because it is said to minimize transmission of noise from the motor. However, on this Numark, it is more of a large rubberband than a "belt." If anybody has seen how rubberbands melt when fastened to something over time, this rubberband belt is going to deteriorate, changing the turntable speed. A "belt" should have been something like the belt in an automobile radiator fan with cloth or fiber woven into it, and wrapped around a smaller disk or gear whereas this Numark band is wrapped around the outer edge of the platter.


- Many of these albums aren't in CD or are difficult to find. For example, none of the xmas albums are in CD. Some of the classical albums I have may be in CD, but are difficult to find.
- With many dozens, of hundreds of albums I have, why should I pay $15 - 25 dollars (totaling several hundred dollars) for CDs when I can convert the albums I have to CDs.
- CDs from music produced in contempory digital studios may be high quality, but I have found some CDs from old analogue music have been very poor quality. The CD producers may have taken care in making quality conversions for major musicians, but poorly for less popular musicians. I should get better quality from my own conversions than the commercial CDs.

Hey, I am not about to buy another turntable. The turntable and the box it came in is huge, and would cost as much as it is worth to ship it, if I resold it. I got screwed, but please don't rub it in. I am going to do the best I can with it. I'll look up the specs on the existing cartridge. If it appears it would cause damage to my vinyls or is of poor quality, then I'll get another cartridge. And I'll also get some sort of test record.

Right now, I am recovering from a computer crash and got other things to attend. It is past time for converting the Christmas albums, with 11 months until next season, but I'll have to at least, test the turntable, in the next few weeks.

Thank you, hydrogenaudio audiophiles, for your help.
