Hi, This is about my old ADI-8 and new ADI-8 mklll, I just do not know where I should post my question..

What input/output level shall I use? My old ADI-8 I always have used +4 in and out. Now when having two mklll and two of the first generation I m not shure wich level I shall use.. I connect them via db25 to my Raydat pcie card via Toslink Shall I use +24 or +19? is there any advantages regarding headroom and quality`? I rcording in Steinberg Nuendo @48kHz 32 bit float(24bit)

Can anyone please explain what the differences are except higher or lower level in and out..
