may

have

too

much

separation

and

sound

exaggerated.

Adjusting

the

panorama

circuit

to

widen

or

narrow

the

stereo

stage

wil

l

correct

most

will

provide

an

indication

of

the

STEERING

LOGIC

DISPLAY:

This

five

pro-

vides

a

visual

indication

of

As

an

example,

a

center

front

,

such

as

dialog,

will

illuminate

the

center

LED

while

surround

signals

will

illuminate

the

bot-

tom

LED.

During

use

with

a

stereo

signal

the

entire

constantly

change

illumination

levels

on

a

dynamic

basis.

A

monophonic

audio

source

wil

l

only

il

luminate

the

center

LED.

Because

of

the

wide

dynamic

range

of

Digital

Servo

Logic(tm),

when

no

audio

signal

is

present,

the

LED

indica-

tors

may

differ

in

illumination

as

a

result

of

normal

produc-

tion
