Do you mean all channels?
Yes we could said Channels,
When i play music in my Yamaha 1065 they show that the music is out 5.1 or 7.1 if i use the seven channel enhancer, all the 7 speakers plus the sub lights up in the display that mean are active and you can hear music thru all the speakers.
On this receiver when i play music they only show the two front channels and the other 5 speakers are not light up in the display, you cannot hear music form the other 5 speakers just from the front, all the speakers are active and configured with the MCACC, that is not the case when you watch a movie they show all the speakers.
If anybody that have the same receiver play some music Cd or MP3 and let me know how many speakers the receiver show up in the display, to see if the problem is my receiver or the way the receiver works.
