I'm an enginner and don't know how volume works

>you need to have the volume at close to 0dB to reach the line out voltage level. Ideally you should put the fuse to 0dB and then adjust volume using the car stereo

Is that just in theory? Would that be bad for the MP3 player, being used constantly as top volume? Would it make the battery deplete faster, make the battery and player heat more, and potentially lead to premature failure? And wouldn't that decrease signal to noise ratio?

Probably uses very slightly more energy, but it improves SNR (not that you care).

Pingouin:
Ok, thanks!

gomezz:
I have actually got into the habit of setting my Sansa Clip+ to -3dB below line level as otherwise on those occasions I was feeding my Satechi FM transmitter rather than a direct connection is was overloading it and running it into clipping and distortion.

Pingouin:
Yes, that's why I was asking is setting up at db wouldn't result in poor SNR, but saratoga hints that it's actually the opposite?
I still don't push my Fuze+ all the way up (but close) as I now get decent volume by having set up the EQ on my stereo for AUX input up.
