John, Since I own an older Rotel amplifier, I am curious about this unit. Given that you are giving the level as an index value, is this amplifier controlled by an app or something? When you give the levels as "45" and "72," what is the maximum value. If the maximum value is 100 and these represent percentages, the values would seem to me to be low, but if they represent audio level in DB, then they might not be. Make sure there isn't an "Audio Mute" button that reduces the output by 40DB or more for conveniently reducing volume when one answers a phone, for example.
When I plug my iPhone into my stereo, it seems as though that running it at full volume results in a signal that is similar in level to my tuner and a CD player. I have some other devices, such as an old Zenith VCR, that has a level that is really quite low. In other words, there is some variability of levels from the variety of input devices that we commonly use these days. Still, these lower levels don't explain not having enough signal to trigger your subwoofer, there seems to be something else at play.

I have just purchased a rotel a12 integrated amplifier and find that at default level of 45 I cannot hear anything from either earphones or speaker. If I put it up to about 72, I hear things, but I have to put sources quite high -- including bt from the iphone. Is this normal for this unit? Also, I cannot get my subwoofer to work, the preamp output does not seem to be enough. -- Your life is like a penny. You're going to lose it. The question is: How do you spend it?
