of

the

insulation

(leaving

only

the

Unscrew

the

knob

(for

the

SPEAKER

connection

terminal

to

which

the

speaker

connection

wire

is

to

be

connected)

until

the

wire

can

be

inserted

into

the

hole

at

the

top

of

the

rear

part

of

the

knob.

Each

speaker

connection

wire

should

be

inserted

securely,

taking

care

that

it

does

not

contact

any

other

terminal.

Then

turn

the

knob

to

tighten

the

knob

securely.

The

speaker

connection

wires

should

be

no

tonger

than

necessary.

*

Be

sure

that

the

connection

wires

are

each

connected

to

the

speaker

system

that

corresponds

to

that

terminal.

Note

that

there

are

two

terminals

(one

positive

and

one

negative)

for

each

speaker

system

cabinet.

The

red

terminal

must

be

connected

to

the

positive

(+)

terminal

on

the

speaker

system,

and

the

black

terminal

to

the

negative

(-)

terminal

on

the

speaker

system.

If

connections

are

not

correct,

the

sound

reproduced

from

the

speaker

systems

will

seem

unnatural,

with

insufficient

stereo

effect,

sound

will

seem

localized

between

the

speaker

systems,

and

low-range

sound

will

be

unsatisfactory.

Be

sure

that

the

impedance

of

the

speaker

systems

is

within

the

specified

range

for

this

unit.
