Speaker setting examples
Here we describe a number of speaker settings for different
purposes. Use these examples as guides to set up your system
according to the type of speakers used and the main usage
purpose.
[1] DTS-ES compatible system
(using surround back speakers)
q Basic setting for primarily watching movies
This is recommended when mainly playing movies and using
regular single way or 2-way speakers for the surround speakers.
• Set the front speakers with their front surfaces as flush with
the TV or monitor screen as possible. Set the center speaker
between the front left and right speakers and no further from
the listening position than the front speakers.
• Consult the owner’s manual for your subwoofer for advice on
placing the subwoofer within the listening room.
• If the surround speakers are direct-radiating (monopolar), then
place them slightly behind and at an angle to the listening
position and parallel to the walls at a position 60 to 90 cm above
ear level at the prime listening position.
• When using two surround back speakers, place them at the
back facing the front at a narrower distance than the front left
and right speakers. When using one surround back speaker,
place it at the rear center facing the front at a slightly higher
position 0 to 20 cm than the surround speakers.
•We recommend installing the surround back speaker(s) at a
slightly downward facing angle. This effectively prevents the
surround back channel signals from reflecting off the monitor or
screen at the front center, resulting in interference and making
the sense of movement from the front to the back less sharp.
w Setting for primarily watching movies using diffusion
type speakers for the surround speakers
For the greatest sense of surround sound envelopment, diffuse
radiation speakers such as bipolar types, or dipolar types, provide
a wider dispersion than is possible to obtain from a direct
radiating speaker (monopolar). Place these speakers at either
side of the prime listening position, mounted above ear level.

With this set, speaker(s) for 1 or 2 channels are required to
achieve a 6.1-channel system (DTS-ES, etc.). Adding these
speakers, however, increases the surround effect not only with
sources recorded in 6.1 channels but also with conventional 2- to
5.1-channel sources. Furthermore, all the DENON original
surround modes ( page 24) are compatible with 7.1-channel
playback, so you can enjoy 7.1-channel sound with any signal
source.
2 Number of surround back speakers
Though the surround back channel only consists of 1 channel of
playback signals for 6.1-channel sources (DTS-ES, etc.), we
recommend using two speakers. When using speakers with
dipolar characteristics in particular, it is essential to use two
speakers.
Using two speakers results in a smoother blend with the sound
of the surround channels and better sound positioning of the
surround back channel when listening from a position other than
the center.
2 Placement of the surround left and right
channels when using surround back speakers
Using surround back speakers greatly improves the positioning
of the sound at the rear. Because of this, the surround left and
right channels play an important role in achieving a smooth
transition of the acoustic image from the front to the back. As
shown in the diagram above, in a movie theater the surround
signals are also produced from diagonally in front of the listeners,
creating an acoustic image as if the sound were floating in space.
To achieve these effects, we recommend placing the speakers
for the surround left and right channels slightly more towards the
front than with conventional surround systems. Doing so
sometimes increases the surround effect when playing
conventional 5.1-channel sources in the 6.1 surround or DTS-ES
Matrix 6.1 mode. Check the surround effects of the various
modes before selecting the surround mode.
• Set the front speakers, center speaker and subwoofer in the
same positions as in example (1).
• It is best to place the surround speakers directly at the side or
slightly to the front of the viewing position, and 60 to 90 cm
above the ears.
• Same as surround back speaker installation method (1).
Using dipolar speakers for the surround back speakers as well
is more effective.
• The signals from the surround channels reflect off the walls as
shown in the diagram above, creating an enveloping and
realistic surround sound presentation.
