I have a NAD T785 AVR. Pro setup was done by my dealer in May 2008. A couple days later I noted back channels were listed in the setup whereas I have none ( 5.1 surrounds only ). I thought this was strange but I ignored it: The front speakers are Dali 400 Helicons which my AVR measured as "large". So I deleted the back channels and set the sub crossover to 60HZ for the advantages of the increased Audyssey control of the Sub performance. My Audyssey light glows red.
Sound is great so my question is really the back channels indications and my raising the crossover point and is there a worthwhile upgrade to the Pro software I should talk to my dealer about? I have to say the sound is really great and more than anything I note the placement and clarity in the vocals ( CD source ).
Thanks
Bill
