[CAVEAT]
mixing consoles for professional applications come provided with a signal path / level normograph,
depicting all paths and levels across inputs, outputs, insert points, matrix, auxes and subgroups... as do quality audio interfaces, too.
which i rate Helix Rack to be, to an extent - it's just the lack of this documentation from its Manufacturer to push me into thinking
the "professional" adjective attached to the text on its user manual is misplaced, or used for mere marketing hype.
[END CAVEAT]
That can certainly be true in - I suspect a large part :) -
there is seldom a manufacturer "badmouths" their own products.
Peronally I do like a thorough technical spec sheet.
Then I will have a yardstick to measure that against my own tastes & hearing.
(just my two cents)
