Hi everyone, So I've recently decide to take the plunge towards Atmos and purchase a Pioneer SCLX701. I'm quite new to these home theater setups so would like help in running a 4 atmos speaker setup with 7 channels (7.1.4). I know this box is cable of doing this providing some sort of external amplifier I read but I have no clue what that means and how to go about doing it. I know how to setup the 5.1.4 using the amp itself but what I'm interested in is how to use a second 2 channel amp to power the rear atmos speakers. Can anyone recommend a budget 2 channel external amp which will do the job for the rear atmos speakers just fine? Also can anyone provide a tutorial as to how to go about setting up the second amp (settings for atmos on the second amp etc) Any help would be greatly appreciated.
