DAC level on remote -security issue

As i understood i have to make attenuator IN to feed preamplifier. I am worried about the easy possibility accidentally to press “DAC level” button on remote. What happen in this case? Is this a way to damage preamplifier or speakers due to strong increasing of volume level?

PS i have Junior version

The next release of the OS will allow you to set an option to disable that button on the remote.

Most people probably don’t need the attenuator for driving a preamp, preamps expect a line level input.

Similarly amps expect an input that’s around the maximum that the DAC outputs. It may get loud if the DAC is at 100 and your preamp is at it’s max. Still it’s not likely to physically damage your speakers since once again these levels are sort of “normal”.
