Cardas Burn-In LP


Hi:
I received my Cardas Burn-In LP today. I'm using a new rig, for me at least. LP12 (10 years old), new RB-1000 arm and Rega Exact 2 cart. I've been playing with the various sweeps on the LP and they do what they should. I read through the other uses for the LP and saw that the 1/2" wide blank (no grooves) sections on side 2 can be used to check tonearm balance and settings. It says the arm should track slowly toward the center. Well mine races across these areas and actually jumps a few grooves into the next section. My table (particularly the path of the arm) is dead level so I'm questioning the set-up of the arm. My dealer set it up, as I have NO experience with this stuff.

Is this a serious thing that should be addressed? If so what do I ask my dealer to check?

Thanks!

You're probably right! You know how it goes when something causes some doubt to creep in.

If the anti-skate was off in that direction how would it effect the music? Would it causes an imbalance between channels? I'm apt to thrust using the Cardas LP with it's other test tones to look for channel differences.
I have the Cardas Sweep as well and would agree that the blanks are certainly not the be-all/end-all in setting anti-skate. That being said, in my setup the arm moves very, very slowly in the "outer" blank and hardly at all in the inner blank closest to the label. If yours is literally shooting across the blanks and skipping towards the label I would think you might try increasing anti-skate, not decreasing it.

Ultimately, though, you want to set by ear. There are some great posts in the archives here from Doug Deacon with respect to setting anti skate by ear-do a search for those.

Finally, if you don't have a digital stylus force gauage or protractor, invest in a cheap one (they need not be expensive). Even though a dealer has set it up, things can get out of wack, particularly if you've transported the table home from the dealer's after setup. You have a nice table/arm/cartridge and proper alignment/VTA and antiskate are critical to realizing its potential. There is a ton of good info easily available here and at vinylasylum that you can quickly pick up on to get things in order yourself.
