4cm and Power amp

Is there a way to just use the power-amp from a Marshall head in 4cm?

Yes there is but can you explain why?

Basically 4CM puts your amp's pre-amp into the POD HD's FX Loop and always has a connection to the amp's power amp. 

If you  want to use the Marshall Power amp  only then simply turn off the FX loop on the Pod HD.   This will sound very lifeless unles you use a modelled amp from the POD also.

I use the PODHD into a Marshall power amp.  Don't use the 4cm method.  Just use the normal output set to Direct Studio Mode into the effect return of the Marshall.  Make sure you have the effect return volume on the Marshall set where the return volume from the PODHD is not overdriving the power amp.  Mine is set to 75%.  I did this by comparing the PODHD into the effect return to playing normally through the Marshall.  If you don't do this you will reduce the life of your tubes quite a bit.  I've also found a slightly cooler tube biasing seems to help, atleast with heavier tones.

Seems like the PODHD likes to have the Master Volume almost all the way up and the Preset's Amp Volume at about 40% for heavy tones and %90 to %100 for clean tones - your mileage may vary here too.

Hope this helps...
