SYSTEM CONFIGURATION
Surround Speakers for 6.1 Systems
A 6.1 surround speaker adds an additional center
back surround speaker to the system, enabling you to
enjoy the benefits of advanced surround modes such
as Dolby Digital EX, DTS-ES and Harman Kardon’s
proprietary Logic 7/7.1 processing.
To step up to a 6.1 system, first place the speakers
for a 5.1 system, as shown on page 18. The “sixth”
speaker should ideally be placed at the center of the
room’s rear wall, pointing directly toward the front
center channel speaker.
NOTE: The 6.1-channel configuration is not recom-
mended for the AVR 240. We strongly recommend
a 7.1-channel installation as described below. When
6.1-channel materials are played through a 7.1-chan-
nel system, the same surround back channel informa-
tion is played through both the left and right surround
back speakers.
If you are only able to install a single surround back
speaker at this time, you will not be able to run the full
EzSet+ 7.1-channel calibration procedure. In that
case, we suggest you install all of your speakers
except the surround back speaker, and run the
EzSet+ procedure for a 5.1-channel system (see
page 24). After EzSet+ has finished, connect the sin-
gle surround back speaker to the left Surround Back
Speaker Outputs 9. Then follow the instructions
starting on page 26 for manual setup to manually
configure your surround back speaker.
We recommend that you consider adding a second
surround back speaker as soon as possible.
Surround Speakers for 7.1 Systems
For the ultimate home theater experience, a 7.1 sur-
round system uses both traditional surround left/right
channels and a surround back left/right speaker pair.
In a 7.1 system, the front left/center/right speakers
remain in the same place as they would be for a 5.1
or 6.1 system, but due to the number of speakers
involved, the placement of the surround speakers is
different.
In a 7.1 system, you should place the main surround
left/right speakers at the 90-degree point on our cir-
cle. A good way to visualize proper surround speaker
positioning for 7.1 is to place the speakers directly to
the left and right of the ears of someone sitting in the
prime listening spot. The two speakers should ideally
face toward each other.
The additional set of Surround Back Left/Right speak-
ers is placed at about 150 degrees on the circle,
pointing inward toward the listening area. The easiest
way to visualize the placement of these speakers is to
place the surround back left speaker directly opposite
the right front speaker and to place the surround back
left speaker directly opposite the left front speaker.
