Jerry, it works as you say..reads the room..and you would have to run the spectrum tool again ..if you think the room needs it...this would mean..a minute of white noise thru your speakers...could be annoying to some folks..

The good news..I don't think you will have to vary the signal/freq again...Initially..the big thing..it finds the frequencies that we are missing...you still can compensate with the 3 band knob eq..and it actually will work better after the RAC is active....unlike the muddy sound you mentioned..

Gary M is going to type a response and I will post it for him...He can go into detail, what he has discovered with the Bose and the Edirol..
