• 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.
• Connect the surround speakers to the surround speaker A jacks on
the AVR-3801 and set all settings on the setup menu to “A”. (This is
the factory default setting. For details, see page 16.)
• 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 satifactory 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.
• 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.
• 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.
• Connect the surround speakers to the surround speaker A jacks on the AVR-3801 and set all settings on the setup menu
to “A”. (This is the factory default setting. For details, see page 16.)
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.
(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.
