7.1
7.1 (available on many Blu Ray discs as DTS-HD Master Audio, Dolby TrueHD or uncompressed LPCM
soundtracks) adds a pair of discrete back surround channels, for a total of 4 surrounds: Left Surround, Left
Back Surround, Right Back Surround and Right Surround.
For a 7.1 setup, the Left Surround and Right Surround speakers should be directly to the sides of the listening
position, on the 90 degree axis. The Left Back and Right Back speakers should be behind the listening
position, with 60 degrees of separation between each surround speaker.
9.1
Contemporary upmix algorithms such as DTS Neo:X and Dolby ProLogic IIz add front height channels,
located directly above the Left and Right speakers. Their ideal height is at 30 degrees above the listening
position.
