Default Denon POA-6600 question

I have a pair of Denon POA-6600 monoblocks. They have a 12VDC input socket for remote power switching. I'd like to use the DC control output from my Nakamichi CA-7 to control these, but it appears to have a 24V signal out.

Questions:

1. Is the DC input of the Denon voltage-free?
2. Can I connect the 2 Denon inputs in series to split the Nak's 24V, or should I just reduce this to 12V level externally?

Thanks for any help!

Yes, I have done that. The schematic is spoilt right where the 12VDC control signal circuitry is situated. I did find a slightly better schematic, but it's not perfect, as the page breaks right there. That's why I posted my question here; just to make sure.

I managed to reconstruct the missing detail from two versions of the schematic. The DC input is not completely voltage-free. I have to check what influence this might have.

I did the setup. Turns out the Denon amps can use the Nak's 25V (measured) signal just as is. This is really nice. Eliminates having to turn off two devices at night
