Bad TC-tracking at 2nd half of Vinyl

[Hannes]

Hi Guys,

I wondered if I´m the only one experiencing this?
When scratching a sample that is at 10min tracktime (e.g. "Ah Yeah" on Superseal Breaks) i find Cross is less reactive/responsive to the TC-Movement as usual.
Also it sounds a bit distorted to my ears.

TC-Vinyls are quite new (2-3 months old) and still give me 99% after calibration.

Hey,

I have a question to that: Have you at the end of the vinyl like the 10 minutes the same quality of Timecode signal?

I know from my turntable (straight version) there I have a losing of quality when I arrive the last lanes.

less reactive/responsive to the TC-Movement as usual

Did you mean that there is a delay or is it not doing the same thing or is the sound only making the problem that the GUI looks like working normal?

Hi Chrisian,

Signalquality seems to be good (97-99%) so i dont think that´s the problem.
It just doesn´t sound as good as usual, kinda sounds distorted and it seems Cross is having a harder time keeping up with TC-movement.

I´ll try different carts and TCs this afternoon.

Maybe it´s just an Vinyl issue since there´s the same amount of information cut into less space on the Vinyl (Vocals tend to sound distorted on real wax as well when they´re cut onto the last part of the vinyl)

Anyway, I´ll keep you updated when i figured it out.

cheers

Hm,

i guess it´s the same as with real wax.
Tc-quality decreases way more than when scratching on first half of the tc-vinyl.
Drop to 72% (20sec tracktime) vs. 61%. (10min tracktime) when scratching.

Skating isn't heavier there ?
I also think that there are usually more dirt when you go so far in the timecode.

TC are clean (i "knosti" them every week ) and AS is at zero.

But i found it to react way better with the ten-years vinyl (which are the last ones i bought), so I´m wondering if you guys changed your wax-cutter?

[Blackbrook]

Correct me if I am wrong or if this does not fit to the thread but shouldn't anti-skating be adjusted to the same value as the weight of the needle i.e. 3.5g -> Anti skating 3.5? This is the way I was configuring my turntables.

Cheers,

Yes,

the anti-Skating is to minimise the drift out of the lines on the vinyl. perfect would be a variable force of anti-skating on every position of the tone arm. But this is not working so normaly you set it depending of the tracking force. This stands in a table.

But this is only to hold the neadle at the track.

You´re right but only for playback!
AS is to compensate the force that pulls the tonearm inwards when it´s playing forward, so equal forces in inward and outward direction would be perfect.
BUT when backspinning/cueing/scratching the forces add and cause your needle to jump off the vinyl (outward).
And thats why we set the AS to zero when we club or scratch (except we mix by pitchriding)

Never changed, but there might be variation from batch to batch I guess.
