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.

(using surround back speakers)
qBasic 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 centimeters (2 to 3 feet) above ear level at the prime
listening position.

Path of the surround sound from the
speakers to the listening position
•When using two surround back speakers, set them at the
back facing front and with both speakers at the same
distance from the listening point. 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.
•Connect the surround speakers to the surround speaker A
terminals on the AVR-4806 and set settings on the setup
menu to “A”. (This is the factory default setting ( page
126).)
wSetting 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
(THX) 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.
