having 2 Mcintosh MC2200 Amps and 1 Mac C-27

I have the MC2255 McIntosh amplifier. The MC2200 is the same amp, without  the power. The first thing  I would do is read the the owner's manual. But you can use these amps in mono. There is a switch on the back to go from stereo to mono. Connect the C27 left output to the left input speaker amplifier and the C27 right output to the right speaker input amplifier. I use a C32 and this works. Again, consult your amp and pre-amps owners'manuals.  Good luck, hope I told you rightt

Thanks that sounds right, now i need to figure out how to hook up the speakers. The mc2200 is not like the mc2255 in the way your amp has bridged mono -mc2200 just mono. i am hooking up 1 speaker to each amp (AR 90 ) Thanks again

The MC2200 is not the same amp as MC2255, it is in fact the meter-less version of earlier MC2205 amp.
