Sorry to keep being a pest, but I really want to understand this.
IMHO, if the Out1 knob supplies 20dB of gain fully clockwise, I'd *still* expect the internal meter to reveal the pre-fader level (i.e. same signal routed to Out1 and Out3 register the same pre-fader level on the internal meter). I'd expect *some other* meter to reveal the post-fader level. Currently, a -10dBFS signal (per Out3) registers as well over +10dBFS on Out1 (i.e., the Out1 meter is pegged and non responsive).
Why am I whining about this - I want to avoid internal clipping so I look at the Output meters when calibrating patches. The Out1 meter is useless IMO because it registers +20dB the actual internal signal and is, most times, pegged at +10dB and non-resonsive. It is not a reflection of the pre-fader level for signals going to Out1. It reflects a presumed fully-clockwise Output 1 knob which is adding some 20-ish dB to the reading.
What if I route 1V to In3 -> Out1. The Out1 meter won't read 1V, it'll read that plus the 20db analog gain stage (or, now are you going to tell me it's a digital gain stage <brain explodes>?)...
Ok, I'll calm down now and drink my coffee
