I have a Yamaha RX-A670 in one HT system and a RX-A1060 in another. Both systems are 7 channel (mains, center, rear surrounds and front presence or "height" as some may call them). I like the Yamaha "7 channel stereo" option for movies and TV. Seems like my surrounds are more active in this mode. I built my surrounds and front presence, so I want to hear them! All four sets are souped-up Radio Shack Minimus 7's and 77's. They sound amazing. Fronts and centers in both systems are Klipsch.
Here is my situation: The A670 in 7 ch mode shows 7 channels lit up on the display and all seven are active. But with the A1060 in 7 ch mode, only 5 are lit up and the front presence speakers are off. I know they are "seen" by the receiver. In all other Dolby Digital modes, they show 7 speakers lit up and you can hear the front presence are on. Anyone know how to set my A1060 so that all seven speakers are active in 7 ch mode? I cannot find a setting for that.
