I just purchased the Sony CRE C20 and went through the set up process. I played around with the Fine Tuning and noticed that I don’t always hear a confirmation tone after completing one of the Solutions.
Am I suppose to hear a tone when adjustment has been made each time?
Don’t really know, it could be just a tone you can’t really hear? But more importantly how do they sound are you happy with the end results.
Yes, that happened to me once or twice, but usually you should hear two tones as the fine tuning option is being applied.
To be sure, I would revert to initial tuning and then start fine tuning again.
