Hello, I'm currently using a Yamaha RX-A880 receiver in a 7.2 set-up L\/R, C, Surr.,Front Presence and two Definitive Tech Powered Subs connected to the receivers Sub 1 and Sub 2 LFE output. My question is I'm not sure if the Sub 2 is active when watching a movie in Surround. Or is the Sub 2 output only active when using a Zone 2 with separate speakers in that zone. When I run a test tone only one Sub shows on the graphic.\nThanks\n\nZone 2 is a two channel zone and will not grab a sub from the main zone. When checking channels, the LFE channel is treated as a single channel since that is what it is actually, a single Low Frequency Effects channel. The single signal can be sent out to one or two subwoofers. When testing speakers, is Sub 2 light green or red?
