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.For THX Surround EX systems (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.

• 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

 

 

60 to 90 cm

 

them slightly behind and at an angle to the listening position and

 

 

 

 

 

parallel to the walls at a position 60 to 90 cm (2 to 3 feet) above ear

 

 

 

 

 

 

 

 

 

 

level at the prime 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 jacks on the AVR-4802R and set all settings on the setup menu to “A”. (This is the factory default setting. For details, see page 16.)

(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 (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.

•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 (2 to 3 feet) above the ears.

• Same as surround back speaker installation method (1).

• Connect the surround speakers to the surround speaker A jacks on the AVR-4802R 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 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.
