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.

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.
Thanks for the help Unfortunately, the only switch is for AV operation or normal operation. As far as fixing the switch I asked two places and they both said it would probably be a few hundred dollars. Having said that I have only listened to the totems through the arcam once and although I liked the dynamics/energy(my terminology may be faulty)the highs seemed harsh compared to the NAD. I am going to try this weekend to rehook up the totems to the arcam - I live in apt in NY and my wife is sick so trying it out right now is not an option. I might post this on the home theater section since my interest is 50 50 but I am wondering what people would do to improve this system if they had 2500 to spend. I should say I listen to mostly rock and most of my music is digital. thinking of building a music server with a mac mini.
