Surround Sound Setup

The speaker layout below shows the standard ITU-R speaker

setting. You can use it to enjoy CINEMADSP, multi-channel

audio sources and THX.

Front Speakers (FR and FL)

The front speakers are used for the main source sound plus

effect sounds. Place these speakers an equal distance from

the ideal listening position. The distance of each speaker

from each side of the video monitor should be the same.

Center Speaker (C)

The center speaker plays the center channel sounds

(dialogue, vocals, etc.). Align the front face of the center

speaker with the front face of your video monitor. Place the

speaker directly between the front speakers and as close to

the TV/monitor as possible.

NOTE: If for some reason it is impractical to use a center

speaker, it can be left out but for best results it is recom-

mended that you use the full system.

Surround Speakers (SR and SL)

The surround speakers are used for effect and surround

sounds. Place these speakers behind the listening position,

facing slightly inwards, approximately 5.9’ (1.8 m) above the

ﬂ oor.

Surround Back Speakers (SBR and SBL)

The Surround Back speakers supplement the surround

speakers and provide for more realistic front-to-back transi-

tions. Place these speakers directly behind the listening

position and at approximately 5.9” (1.8) above the ﬂ oor, the

same height as the surround speakers. Ideally these should

be positioned with the same distance between each other

as is between the front speakers or no less than 11.8” (30

cm).

Subwoofer

A subwoofer is great for not only reinforcing bass frequen-

cies from any or all channels but also for high ﬁ delity repro-

duction of the LFE (low-frequency effect) channel included

in Dolby Digital and DTS software. It is best to position the

subwoofer near the front speakers and turn it slightly to-

wards the center of the room to reduce wall reﬂ ections.

Di-Pole Speaker Layout

Either Di-pole or direct radiating speaker types can be used

for THX surround sound. If you choose di-pole speakers,

please place the surround and surround back speakers ac-

cording to the speaker layout below.
