What is the dimension of the value marked on the Alt-out knob? (0-10) Since it’s a line level output, how do I set to 0dB? Unlike headphone output where it is driven by a headphone amp. Should this Alt-out knob be marked differently so users can set to a more precise level?
I also assume that that is unity – the only reference to levels in the manual is
“Stereo ‘alternative’ output on balanced TRS jacks for connection to +4 or 0dBu equipment such as zone feeds, fill speakers, broadcast or local monitor”
