Amplifier Operations

x SBL DIST. (Surround back left

speaker distance)

x SBR DIST. (Surround back right

speaker distance)

Lets you set the distance from your listening

position to the surround back speakers.

Tip

To enjoy better surround sound, the distance

between the center speaker and the listening position

B cannot be more than 1.5 meters closer than the

one between the listening position and the front

speaker A. Place the speakers so that the difference

in the length of B in the following diagram is no

more than 1.5 meters closer than the length of A.

Example: Adjust the distance B to 4.5 meters or

more when the distance A is 6 meters.

Also, the distance between the surround speakers/

surround back speakers and the listening position

C cannot be more than 4.5 meters closer than the

distance between the listening position and the front

speakers A. Place the speakers so that the

difference in the length of C in the following

diagram is no more than 4.5 meters closer than the

length of A.

Example: Adjust the distance C to 1.5 meters or

more when the distance A is 6 meters.

This is important because incorrect speaker

placement is not conductive to the enjoyment of

surround sound. Please note that placing the

speakers closer than the required will cause a delay

in the output of the sound from that speaker. In other

words, the speaker will sound like it is farther away.

Adjusting these parameter while listening to the

sound often results in much better surround sound.

Give it a try!

x SW PHASE (Subwoofer phase

polarity)

Lets you set the subwoofer phase polarity.

• NORMAL

Normally, select “NORMAL”.

•REVERSE

Depending on the type of front speakers, the

position of the subwoofer, and the cut-off

frequency of the subwoofer, setting the phase

polarity to “REVERSE” may produce better bass.

Besides bass reproduction, the richness and

tightness of the overall sound may also be

affected. While listening from the main listening

position, select the setting that best suits your

environment.

x SUR POS.

(Surround speaker position)

Lets you specify the location of your surround

speakers for proper implementation of the

surround effects in the CINEMA STUDIO EX

modes (page 54).
