Cardas test lp version 2

Doug, that seems like excellent advice. I would add the following as potentially helpful: If the recording of that solo voice or instrument is in a dead space, it should sound life like in scale with no sounds (distortion), or exaggerated size outside of the immediate source of the sound. However, if it is in a live, reverberant space, then the voice/instrument should sound life size but there should also be a wealth of clean/clear sonic information all around that center image of the source. This will inform the listener of the size, shape and character of the space in which the singer/instrument is located.

I borrowed the Fozgometer? last night to check the azimuth on my arm. This is an expensive device that also requires the use of an appropriate test LP. It is quick and gets the job done. Sadly, my arm does not really have azimuth adjustability, but I was able to determine that the channel balance is spot on according to the meter and that my azimuth was extremely close.

I agree that learning to do it by ear is preferable and, it is certainly cheaper. There can be a learning curve, but it can be fun. I appreciate that people like Doug can explain how to do it and what to listen for.

Good additional sonic insights, Peter. A recording in a live space, rather than an anechoic recording booth, does indeed make it easier to hear the size/shape of the solo instrument/voice as well as the space itself. More sonic cues for the ears/brain to pick up on.

Many years before the Fozgometer I owned a share in a Wally Analog Shop, which also allows direct measurement of crosstalk when used with L only/R only test tracks. Minimizing crosstalk is one of the key goals of azimuth adjustment (channel balance is not, azimuth has little effect on that).

After several months, three of the Wally's four co-owners realized that he could adjust azimuth by ear about as well and much faster, with no expensive tools or test LPs. Using the device and seeing the numbers was fun in an audio-geeky way, but if we think for just a moment about what "minimized crosstalk" must sound like it's easy enough to work out what to listen for.

With the "Ultimate Analogue Test LP" and the Fozgometer instructions, there is an additional test for channel balance. It uses an out of phase mono track and the Foz device registers the "center channel" light. If the meter reads "0", then the left channel is completely canceling out the right channel and one can conclude that his channel balance is correct. At least, that is how I interpret the test and results. I agree it has little to do with azimuth but I guess I'm reassured about yet another setting.

I have the Fozgometer and the Ultimate Analogue Test LP. When adjusting for crosstalk (the correct way to adjust azimuth), you're not aligning the stylus in the groove per se. You're aligning the signal generators above the groove which is more important. It's ok if one side of the stylus is a little higher than the other, as long as the coils etc are parallel to the grooves. This is what I found with my Dynavector 17D3 and it sounds great. But, the stylus itself is slightly counter clockwise and the bottom of the cartridge is perfectly parrellel to the record. I'm a big fan of the Fozgometer. It works.
