Dual-Zone Capability: You can use two speaker systems with the
TX-SR706 receiver - a surround-sound speaker system up to 7.1 channels in your
main listening room (Zone 1), and a stereo speaker system in a second room (Zone
2). The Zone 2 outputs allow you to enjoy one source in your main listening
room, while other sources play in remote rooms. Depending on how you configure
the receiver, using Zone 2 will require an additional amplifier and speakers, a
set of powered speakers, or simply a set of non-powered speakers located in a
remote location. You can connect the dedicated Zone 2 stereo RCA line outputs to
a receiver/amplifier or powered speakers in one room while powering a
7.1-channel speaker system in the main room; the output level of the RCA line
outs for Zone 2 can be switched from fixed for variable, so they can be
connected to an amplifier or powered speakers equipped with or without a volume
control. You can also connect a pair of speakers to the receiver's dedicated
Zone 2 speaker terminals and simultaneously power a 5.1-channel speaker system
in the main room. When the Zone 2 speaker terminals are turned on, the Surround
Back speaker outputs do not work. When the Zone 2 speaker terminals are off, the
Surround Back speaker outputs work as normal. The Zone 2 speaker output volume
setting can be controlled with the remote. Only analog sources can be played in
