Setting Up Your Speaker System

This unit has been designed to provide the best sound field

quality with a full five-speaker system setup, using one extra pairs of

effect speakers to generate the sound field plus one center speaker

for dialog, when using Dolby Pro Logic Surround decoding. We

therefore recommend that you use a five-speaker setup. A four-

speaker system using only one pair of effect speakers for the sound

field will still provide impressive ambience and effects, however, and

may be a good way to begin with this unit. You can always upgrade

to the full five speaker system later.

Use of the Center Dialog Speaker Is Recommended

With digital sound field programs No. 5 through No. 16, by using

either the Directional Enhancement circuit or the Dolby Pro Logic

decoder, decoded signals will be output from the center channel.

Therefore, if you want to upgrade the Audio/Video home theater

system, it is recommended to use the center speaker unit.

If for some reason it is not practical to use a center speaker, it is

possible to enjoy movie viewing without it. Best results, however, are

obtained with the full system.

It is also possible to further expand your system with the addition

of a subwoofer and amplifier. You may wish to choose the

convenience of a Yamaha Active Servo Processing Subwoofer

System, which has its own built-in power amp.

5 Speaker System

This is the recommended speaker

system, providing the best sound

effects.

With sound field programs No. 1

through No. 4, using effect speakers

reproduces the effective sound field.

With the sound field programs No. 5

through No. 16, the center speaker

provides precise center localization.

Center Mode—Set to NRML or WD.

(See page 23.)

4 Speaker System

Simple system without center

speaker.

With sound field programs No. 1

through No. 4, a sound effect matching

that of a 5-speaker system can be

obtained. With sound field programs No.

5 through No. 16, center sound is output

from the left and right main speakers.

Center Mode—Set to PHNTM.
