Sdcampbell, thanks for the clarification. I have been wondering about some of the problemss people have posted on using and calibrating the Fozgometer. As Mike Fajin mentioned to you, the unit is sensitive to extraneous signal noise so you have to use good quality connectors and a clean signal. I found this out while using one of my phono preamps and a LOMC cartridge; the preamp had developed some signal noise in one channel that was affecting the Fozgometer and making it difficult to set azimuth. So I used the tonearm cables directly into the Foz. That's the preferred method but when you have a cartridge with low output, the range of signal output is reduced so it reduces the sensitivity of the adjustments in azimuth.
Your mention of the Fozgometer being recalibrated to a 30dB sensitivity got me to thinking that I could do the same in order to have a wider range of sensitivity for LOMC cartridges. I'm assuming that's how it would work. I'll have to experiment to see. Or have you already seen that effect?
I know it would cost more to implement but it would be handy to have two signal level settings on the Fozgometer, one for high output cartridges and one for low output cartridges. But that'd make the Fozgometer more expensive for everyone just to make it more convenient for a limited number of users.
Thanks again for posting the information. Helps to understand how these things work.
