Volume Limiter

This is precisely the reason I'd like to have it. I have podcasts I listen to on my e250 on the way to work (while I'm on my bicycle). Sometimes I turn it up (through my vest), so I can't pull it out and look to see how high it is. I'd like to limit the amount I can raise it.
I mean, if it's a setting, I can always go back and change it if I need to.

There is already a setting for this, as mentioned above, it is the equalizer precut.
NorTheBear:
What about this real world scenario:
- In the evening you connect your DAP to your stereo receiver or active loudspeakers and set the volume on your DAP at highest level
- Next morning you forget to rule down the volume before you put on your earphones and then it will really hurt (believe me or try it out yourself :-)
I am throwing this into discussion because I see at least three aspects of controlling the volume:
First, set the volume to a configurable maximum level so that you can't exceed that value by mistake if you are playing around with the volume control buttons (original poster's inquiry)
Second, allowing me to have a kind of "LINE OUT" mode that supplies a strong signal (max volume) to the amplifier of my stereo device.
Third, avoiding any physiological ear damages even if you have forgotten to reset the volume to a 'normal' level. I can think of a configurable start level after booting the firmware.
Just my 20 cents.
Cheers, Norbert.

You can do this by using the equalizer pre-cut. Shoe's post three above yours explains how to put these settings into the fixed.cfg file if you want this to be the default whenever you start Rockbox.

You can do this by creating a .cfg file with whatever settings you want to use when you connect via line out and then simply loading that .cfg file when you use the line out.

Again, you can do this by putting a volume setting into your fixed.cfg file.

When I bought my headphones, in the manual it had a maximum number of Hertz (mabey something else) that they could handle. could you set a limmit on that?
