This is not DSP but really changing the analog parameters. On inputs and outputs you can configure the "max level":
For inputs (the help text in the Configurator):
"Maximum input RMS level: the amplifier gain is adjusted to make it match the maximum RMS voltage at the speaker output (Factory Setting: 2 VRMS)
An excessive value requires to push the volume control higher and needlessly prepares the amplifier to high power demands, with slightly increased energy consumption and heat dissipation: this is especially the case if you connect the earphone output of a portable player (whose output voltage is limited to protect your ears) without choosing the corresponding low value preset; a too low value leads to clipping of the most dynamic records."
For outputs (no help text is present in the configurator so in my own words): the level allows one to match to the input sensitivity of the device connected to the output. If it's set to 2Vrms than that 2V is the voltage which corresponds to maximum line output level. If the device (eg. an active subwoofer or surround amp) you connect to the output has an input sensitivity of 4V you'll never reach maximum volume so one can match it by adjusting this parameter. If the device has an input sensitivity of 1V there's a risk of clipping. You can check the input sensitivity in the manual of the device or consult the manufacturer of course.
