CONNECTIONS

This unit uses acoustic field effects and sound decoders to bring you the impact of a real movie theater or concert hall. These effects will be brought to you with ideal speaker positioning and

connections in your listening environment.

Speaker channels and functions

■

Front left and right speakers

The front speakers are used for the front channel sounds (stereo

sound) and effect sounds.

Front speaker layout:

Place these speakers at an equal distance from the ideal listening

position in the front of the room. When using a projector screen,

the appropriate top positions of the speakers are about 1/4 of the

screen from the bottom.

■

Center speaker

The center speaker is for the center channel sounds (dialogue,

vocals, etc.).

Center speaker layout:

Place it halfway between the left and right front speakers. When

using a TV, place the speaker just above or just under the center of

the TV with the front surfaces of the TV and the speaker aligned.

When using a screen, place it just under the center of the screen.

■

Surround left and right speakers

The surround speakers are for effect and vocal sounds while

playing back more than 5.1-channel source. When used with no

surround back speaker while playing back more than 6.1-channel

source (including surround back channel), sound of surround back

channel is distributed between the left and right surround speakers.

Surround speaker layout:

Place the speakers at the rear of the room on the left and right sides

facing the listening position. They should be placed between 60

degrees and 80 degrees from the listening position and with the

speaker tops at a height of 1.5 – 1.8 m from the floor.

■

Presence left and right speakers

The presence speakers are used for front effect sounds. When used

in combination with the sound programs (☞

p. 53), a sound with a

richer and more spatial presence is possible.

Presence speaker layout:

Place the left and right presence speakers 0.5 – 1 m to the outside

of the left and right front speakers respectively. The tops of the

presence speakers should be 1.8 m above the floor.

■

Surround back left and right speakers

The surround back speakers are for rear effect sounds while

playing back more than 6.1-channel source. When used with only

one surround back speaker while playing back more than 7.1-

channel source, sound of the left and right surround back channel is

mixed and output from a single speaker.

Surround back speaker layout:

When used with 7.1ch sound, arrange the left and right speakers

towards the listening position, to the rear of the listening position.

Arrange the left and right speakers at least 30 cm apart. The same

separation as with the front left and right speakers is optimum.

When used with 6.1ch sound, arrange these to the rear of the

listening position.

■

Subwoofer

The subwoofer speaker is used for bass sounds and low-frequency

effect (LFE) sounds included in Dolby Digital and DTS. Use a

subwoofer that is equipped with built-in amplifier.

Subwoofer speaker layout:

Place it to the outside of the front left and right speakers facing

slightly inward to reduce echoes from the wall. You can use one or

two subwoofers and select the position of subwoofers from “Left +

Right,” “Front + Rear” and “Monaural x2” (☞p. 94).
