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
sorround speakers.
Front speakers • Set the front speakers with their front
Center speaker
surfaces as flush with the TV or monitor
screen as possible. Set the center speaker
Monitor between the front left and right speakers and

no further from the listening position than the
60°
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
60°
slightly behind and at an angle to the listening position and parallel to the walls
at a position 60 to 90 centimeters (2 to 3 feet) above ear level at the prime
Surround back speakers
(1 spkr or 2 spkrs)
listening position.
As seen from above
• 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.
(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 • Set the front speakers, center speaker and
from the speakers to the
subwoofer in the same positions as in
listening position
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.
Surround
speakers
• Same as surround back speaker installation
method (1).
Using dipolar speakers for the surround back speakers as well is more effective.
• Connect the surround speakers to the surround speaker jacks.
60°
• The signals from the surround channels reflect off the walls as shown on the
Surround back speakers diagram at the left, creating an enveloping and realistic surround sound
(1 spkr or 2 spkrs)
presentation.
As seen from above
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.
2. When not using surround back speakers

The AVR-550SD 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.
