connecting mono amps to pre amp

Newbie here. I'm 56 and this past year and a half, I've  gotten back into 2 channel. Various amps/pre amps and receivers. I would like to know how to properly connect (2) Mcintosh 2120's to a Mcintosh MA 6100. Have several mac pieces as well as others. But seems Mac is kind of like BMW/Mercedes -European cars with the fact of over engineering or over features, for a lack of better words. Can someone shed some light here with regards to the MONO bloc connection on these? Thank You in advance!!

Go to the rear of your 6100 and you should see 2 small U shaped pieces of metal. Pull them out. Plug the left and right interconnects for the amps into the 2 rca jacks that are labeled preamp.

I'm trying to connect (2) 2120 power amps and run them as MONO the Ma 6100 has only 1 set of pr amp jacks. and 1 set of power amp jacks, The 2120's have a left and right gain on the front and stated in the manual that if you run the amps as mono to the RIGHT only as it is designed to run as mono. and to switch the button on the back of the amp to mono.

What mb1audio02 said is correct, although given your response what he said may not have been worded as clearly as it might have been. You would connect an interconnect between the right channel input of the right channel amp and the right channel "preamp" jack of the 6100. You would connect an interconnect between the right channel input of the left channel amp and the left channel "preamp" jack of the 6100. The left channel input of each amp would be left unconnected. You would set the rear panel switch on both amps to mono, as you indicated.
