6.1-C HANNEL S YSTEMS
A 6.1-channel system can be thought of as a 5.1-channel system with the
addition of a rear center speaker placed midway between the two surround
speakers, and further to the rear than the surrounds. It should be placed at the
same height as the side surround speakers (see Figure 5).
7.1-C HANNEL S YSTEMS
In a 7.1-channel system, two speakers are added for rear fill, in addition to the
surround speakers in a 5.1-channel system. The two additional speakers are
placed on the rear wall or near the rear wall in the ceiling (see Figure 6).
