SPEAKER PLACEMENT
Before you begin to connect cables, it is important to place your speakers
in their correct locations in the room.
Optimally, the speakers should be placed in a circle with the listening
position at its center. The distance from the listening position to the
video display forms the radius of the circle.
The speakers should be angled so that they directly face the listening
position.
Front Speaker Placement
The center speaker is placed either on top of, below or mounted on the
wall above or below the video display screen.
The front left and right speakers are placed along the circle, about 30
degrees from the center speaker and angled toward the listener.
It is best to place the front left/right and center speakers as close to
the same height as possible, preferably at about the same height as
the listener’s ears. In any event, the center speaker should be no more
than two feet above or below the left/right speakers.
Placement of the surround speakers depends on the number of
speakers in your system. If you’re using only two speakers with the
AVR 254, place them in the front left and right positions, and skip to
the Installation section. However, we recommend using the AVR 254
in a 5.1- or 7.1-channel configuration for optimal surround sound
performance.

Placement of Surround Speakers in a 5.1-Channel
System
The side surround speakers should be placed 110 degrees from the
center speaker, that is, slightly behind and angled toward the listener.
If this isn’t feasible, place them behind the listener, with each surround
speaker facing the opposite-side front speaker. See Figure 15. The
surround speakers may be placed a little higher than the listener’s ears.
Placement of Surround Speakers in a 7.1-Channel
System
In a 7.1-channel system, the side surround speakers are placed 90 degrees
from the center speaker, directly to either side of the listening position.
The surround back left and right speakers are placed 150 degrees from
the center speaker, or directly facing the opposite-side front speaker.
See Figure 16.

NOTE: Some speaker manufacturers offer 6.1-channel speaker
systems, which are compatible with 6.1-channel surround
sound formats, such as Dolby Digital EX, DTS-ES Discrete and
Matrix modes and DTS Neo:6 mode. We do not recommend
using the AVR 254 in a 6.1-channel configuration. In fact, the
6.1-channel formats will sound better when played through
a 7.1-channel system. The same surround back channel infor-
mation is played through both surround back speakers, but with
twice the power and clarity.
If you wish to use the AVR 254 with a 6.1-channel speaker
system, place the single surround back speaker directly behind
the listener, but do not connect it until after you have run the
EzSet/EQ procedure for a 5.1-channel system. After the
EzSet/EQ process finishes, connect the surround back speaker
to the Surround Back Left Speaker Output. Then follow the
directions in the Advanced Features section for manual setup
of the surround back speaker.
