Attempting to configure 5.1 with current gear and new Anthem unit-

Thanks for all thoughts. Previous Arcam was indeed a 5.1. as is the brand new Anthem model- Currently, the way the tech was attempting to set up---he was using the CJ Pre and Power amps to power left and right Vandersteen Quatros.  Attempting to use Anthem for Center and rears.  Hasn't worked out so well.  He is having issues getting Anthem to direct sound to left and right in surround mode. Will not switch.
Again, attempting to use Anthem for switching, as I did with previous Arcam. There is no customer support I can call for Anthem.  Again, my recollection is that Arcam had a different configuration??  I may be wrong.  Unless Arcam was set up to power all speakers for video and dvd, and I was only using CJ units for 2 channel. I did not have any peripheral hardware ---as I said, I am not a tech, and 
hoping to figure this out so I can get five channel sound.  One thing--we did not EQ room---not sure this matters as again, cannot figure out how to use the Anthem to direct sound to all five speakers I am using in that room.   Thanks.

Thanks for all input----again, not being a tech person, a lot of this is way beyond me.  And will consult with my tech assist, with all people have shared.   He is very good----I am just baffled as to what changed from previous work around with CJ equipment, and where I am now---of course I have no recognition of what was done previously, and/or the Arcam could do something in relationship to the CJ gear that the Anthem cannot?  Not thinking so.
