HI,
I have a problem of independently adjusting the volume of HeadPhones. (HDSP-9632)
Way too loud and not fine adjustable? I don't believe that is possible, I can't figure it out, I need help...

In Hammerfall settings I have HPs output set to -12dB. It is still too loud.
(Headphones are plugged in the 1/4" HP jack in break out cable, 15pin)

I tried various combinations, routings, etc in the HDSP mixer, routings in Playback section and the choices of Monitor phones, my problem is that I can not lower the volume of H-Ps independently.
(I can lower it, but the MAIN-out volume goes down with it??)
With tests of various routings I can monitor channels, but once I try to lower the volume of HPs, the volume goes down with the Master volume?
What I do not understand is why turning down headphones, also turns down Master volume and when I turn headphones down, bringing up output main volume (if it was down), does nothing, I see sound playing in playback readouts, nothing out of spekers... or I have some wrong config?

The available manual is very different from what shows the updated hardware/software, for example I have only one page in Hammerfall DSP settings, it's ok, if that's what it is supposed to be.

Any help greatly appreciated...TIA
