• The aux 1 channel becomes the surround back right
channel (sbr)
• The aux 2 channel becomes the surround back left
channel (sbl).
THX recommends that these speakers be placed together, facing
forward at the rear of the room for best Advanced Speaker Array
effects as indicated below:
Figure 5-3: Setup for 7.1 surround sound.
An alternate approach places these speakers at the rear of the room,
generally at about ±150° from front-and-center (presumably, the
middle of the video screen), as indicated below:
Figure 5-4: Alternate 7.1 surround sound setup.
Specifically,
• The aux 1 channel becomes the surround back right channel
• The aux 2 channel becomes the surround back left channel.
The indicated angles are measured from front-and-center, and are
approximate guidelines only. (Try to stay within about 10° of the
angles indicated, and try to maintain as much symmetry as possible.)
