I wonder if anybody has experience with optimal setup of the phono sensitivity and how to avoid signal clipping.
My setup is an Oracle Delphi turntable w/Ortofon Kontrapunkt B cartridge connected to a Devialet 200, connected to a Mac Mini running Audacity 2.1.1.
Technically everything works fine, and I am very happy with sound quality via the Devialet phono inputs set to MC mode - low noise, no hum whatsoever.
I just tried to digitize a vinyl record for the first time, and examining the sampled music in Audacity, I realized that in a few cases during high signal peaks there was noticeable clipping. I had the phono sensitivity set to MC and 300uV on the Devialet. After changing the sensitivity to 600uV, the clipping disappeared - at least for the record I wanted to transfer.
So I am wondering if anybody else has a similar experience, and how did you actually determine the correct sensitivity setting for the Devialet phono inputs (other that the way I did) ?
I am also wondering if the clipping actually takes place in the phono preamp section of the Devialet or somewhere else in the chain. Points of view would be appreciated.
Since a very small amount of clipping is not really audible, I'm guessing that it is very likely that a lot of people have the sensitivity on their phono inputs set wrong, or at least that seems to have been the case for me.
