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)
(1) 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
Front speakers
Center speaker
surfaces as flush with the TV or monitor
screen as possible. Set the center
speaker between the front left and right
Monitor
speakers and no further from the
Subwoofer
listening position than the front speakers.
60°
• Consult the owner's manual for your
Surround
subwoofer for advice on placing the
speakers
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
60°
walls at a position 60 to 90 centimeters above ear level at the prime
listening position.
Surround back speakers
• When using two surround back speakers, place them at the back facing the
(1 spkr or 2 spkrs)
front at a narrower distance than the front left and right speakers. When
As seen from above
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.
(2) 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.
Path of the surround sound from the
speakers to the listening position
• 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
Surround
of the viewing position, and 60 to 90 cm
speakers
above the ears.
• Same as surround back speaker
installation method (1).
Using dipolar speakers for the surround back speakers as well is more
60°
effective.
Surround back speakers • Connect the surround speakers to the surround speaker jacks.
(1 spkr or 2 spkrs)
• The signals from the surround channels reflect off the walls as shown on
the diagram at the left, creating an enveloping and realistic surround sound

presentation.
For multi-channel music sources however, the use of bipolar or dipolar
speakers mounted at the sides of the listening position may not be
satisfactory in order to create a coherent 360 degree surround sound field.
Connect another pair of direct radiating speakers as described in example
(3) and place them at the rear corners of the room facing towards the prime
listening position.

Surround
The AVR-2802 is equipped with a digital signal processing circuit that lets you play program sources in the
surround mode to achieve the same sense of presence as in a movie theater.
Dolby Surround
(1) Dolby Digital
Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories.
Dolby Digital consists of up to "5.1" channels - front left, front right, center, surround left, surround right,
and an additional channel exclusively reserved for additional deep bass sound effects (the Low Frequency
Effects – LFE – channel, also called the ".1" channel, containing bass frequencies of up to 120 Hz).
Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound
information, from the lowest bass, up to the highest frequencies – 22 kHz. The signals within each channel
are distinct from the others, allowing pinpoint sound imaging, and Dolby Digital offers tremendous dynamic
range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.
