Which reminds me – is there a Kosmo definition of “hot”? @antoine.pasde2 wrote “-10V to +10V typical” (20 Vpp) in the draft here:
but seems you may be designing for closer to 10 Vpp in practice, maybe? (also see the many discussions about the 3340 output levels).
(I guess we should all be responsible audio adults and talk dBs instead, but I find that a bit confusing tbh and not at all helpful when looking at circuits…)
