\rHi Tim:
I am assuming you are looking at the ATM7 for its remote control capability. There is no problem connecting two speakers to the two mono blocks. You can even run both pair of speakers at the same time assuming you Mono blocks have no problem seeing 4 ohm load. Check to see what you speakers are rated at 8 or 4 ohm. Note there is no internal protection with the ATM7 so you would not be able to run a third pair of speakers (The ATM 7 has 7 zones total.) with the first two without adding Impedance Matching Volume Controls on all pairs of speakers. So yes you can run both pair of speakers (as long as they are 8 ohm) at the same time with no problem.
Good luck:
