Center

Mode

Set

the

center

mode

as

described

below,

according

to

the

type

of

center

speaker

being

used.

Normal

mode:

This

mode

is

suited

for

an

arrangement

in

which

the

center

channel

speaker

is

smaller

than

the

left

and

right

speakers.

Signals

below

100

Hz

which

have

almost

no

effect

on

directional

orientation

are

distributed

to

the

left

and

right

channels,

whereas

the

center

channel

output

signals

greater

than

100

Hz.

As

a

result,

the

bass

of

the

left

and

right

channels

increases

the

apparent

deepness

of

the

sound.

Wide

mode:

This

mode

is

suited

for

an

arrangement

in

which

the

center

channel

speaker

is

of

the

same

grade

as

the

left

and

right

speakers.

The

entire

sound

band

from

low

region

to

high

is

output

to

the

center

channel

to

provide

an

exciting

sound

field

for

your

enjoyment.

Phantom

mode:

Use

this

mode

when

center

channel

speaker

is

not

used.

A

directional

emphasis

circuit

provides

signal

reproduc-

tion

which

is

electrically

oriented

to

the

center

and

this

provides

an

exciting

sound

field

for

your

enjoyment.

Delay

Time

The

optimum

delay

time

will

differ

depending

on

the

listening

position.

Referring

to

the

chart

at

right,

set

the

optimum

delay

time

for

your

room's

space

and

seating

position.

For

example,

when

the

distance

from

the

front

speakers

to

the

listening

position

is

20

feet

and

that

from

the

rear

speakers

to

the

listening

position

is

15

feet,

the

optimum

delay

time

will

be

20

ms.

The

variable

range

of

the

delay

time

differs

depending

on

the

mode.
