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

surfaces as flush with the TV or monitor
screen as possible. Set the center

speakers and no further from the listening

position than the front 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

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.
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.

• Set the front speakers, center speaker
and subwoofer in the same positions as
in example (1).
• It is best to place the surround speakers

effective.
• Connect the surround speakers to the surround speaker jacks.

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-2803 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.

• 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

• 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 centimeters above ear level at the prime listening position.
