Setting Azimuth


Details:
VPI Scoutmaster
JMW 9 standard tonearm
Soundsmith Zephyr cartridge band new
Using a Fozgometer and Hi Fi News Test LP both also brand new
I'm measuring at the interconnects off the turntable.
I cannot seem to achieve a proper azimuth that will give even channel balance. The only adjustment on this tonearm is the counterweight which is weighted a the bottom so turning it side to side should effect azimuth. Only extreme changes are affecting channel balance. I changed the interconnects in case they were causing the problem, but I get the same results. The right channel is a few decibels louder no matter what I do to the azimuth unless I make an extreme adjustment which has the tonearm cocked to one side and obviously this is not correct.

The Fozgometer measures crosstalk and channel levels, and that's it. Good enough to get you in the ballpark but not worth $250 IMNSHO. Minimizing phase error is what's important, which isn't necessarily at the same azimuth setting as minimum crosstalk.
And adjusting azimuth is done to minimize crosstalk. Period.
Wrong. You heard what I did with your neighbor Michael's rig. Minimizing crosstalk was not the objective.
Lewm: No, I take no issue with the point about azimuth adjustment not being a way to change channel balance. Far from it.

Doug: I agree with your remark about overpriced gadgets, but adjusting by trial and error without measurement can be akin to throwing darts blindfolded. I charge a nominal fee for my alignment service and get raves every time.
