Help using integrated as power amp


I have a NAD T747 receiver powering some Totem Rainmakers. Problem is that the 747 manual states the receiver should be used to drive 8 ohm or higher. I have an old arcam alpha 9 integrated amp and was thinking of testing out using this as a power amp for the rainmakers and the 747 as the preamp. Can anyone explain how to do this? Do I need to be careful with the volume controls, I am not even sure in this situation which volume controls work.
Thanks.

I bought the 747 because: one, I wanted to be able to use it for watching movies and two, the input selector on the arcam doesn't work anymore. It will work for a while and then the sound will just drop out. When I spray deoxidizer on it that helps but never solves the problem. I was thinking of buying a NAD C275 power amp and running the front speakers off that. Do you think that will improve the sound quality from the 747 or do you think my best bet is to buy another integrated(used). Unfortunately, my budget for that would be less than a 1000, ideally even less than that, as I want to first buy a totem storm sub and center channel.
Any idea how much $$ it would cost to fix the switch on the Arcam?

adding more 'stuff' won't help, if you were satisfied with the original gear.

Maybe 2.1 for HT? works for me, without additional complexity.
Alternative, buy a used NAD c272 and see what that does for you. Rainmakers well powerd can have some very strong bass. Trading the 747 for one of the bigger NAD receivers or one from another mark could also help. Adding a subwoofer to an underpowered system will not increase overall enjoyment in my opinion.
to answer your actual question, connect an rca cable from the front preouts on the rear of your nad receiver to the "pwr in" sockets on the rear of your arcam, then press the "pre/pwr" switch on the rear of your arcam (to make it fuction as a power amp). good luck.
by this connection, your arcam will be functioning solely as a power amp--all the volume, tone, etc. will be controlled by your nad. keep the volume on the arcam turned up full.
