OPERATING

THE

SYSTEM

Each

Compositions

Overture

OVTR

1

speaker

system

contains

a

built-in

powered

subwoofer.

For

your

convenience,

the

system

is

not

fitted

with

a

power

on/off

switch.

Instead,

an

auto-sense

circuit

will

instantly

switch

the

system

on

when

an

audio

signal

is

present,

and

will

automatically

revert

to

standby

(drawing

only

7

watts)

when

audio

is

absent

for

a

minimum

of

10

minutes.

A

dual-color

“Power

On”

LED

(see

Figure

8

below)

glows

red

when

the

amplifier

is

the

stand-by

mode

and

green

when

the

amplifier

is

on.

If

on/off

switching

is

desired,

connect

the

OVTR

1’s

ac

power

cord

to

an

ac

switched

outlet.

If

you

plan

to

leave

for

an

extended

period

of

time

(e.g.,

vacation),

switch

the

system

off

(or

unplug

the

ac

power

cord).

This

product

is

designed

for

(USA)

120

Vac

use

only.

Do

not

connect

it

to

any

other

line

voltages.

1.

After

speaker

wiring

has

been

completed,

connect

each

speaker’s

ac

power

cord

to

the

nearest

ac

receptacle.

You

should

see

an

LED

illuminate,

indicating

the

amplifier

is

on

(see

Figure

8

below).

If

not,

verify

the

ac

outlet

is

delivering

power

or

refer

to

Troubleshooting

2.

Check

the

speakers

for

playback

by

first

setting

the

audio

system

volume

control

for

a

minimum

level,

and

then

applying

power

to

your

system.

Play

a

favorite

music

or

video

segment

and

increase

the

volume

control

to

a

comfortable

level.

NOTE:

You

should

hear

balanced

audio

reproduction

across

the

entire

frequency

spectrum.

If

not,

perform

the

following

procedure:

1.

Unplug

the

speaker’s

Then

turn

the

speaker

around

to

access

the

fuse

holder

on

the

rear

panel

(refer

to

Figure

2.

Using

a

small

flat-blade

screwdriver,

place

the

tip

in

the

indent

and

turn

the

fuse

cap

counter-clockwise.

3.

Remove

the

Doing

so

will

void

the

warranty.

4.

Insert

the

CARE

OF

YOUR

SPEAKER

SYSTEM

The

dark

grey

metallic

finish

does

not

require

any

routine

maintenance.

When

needed,

use

a

soft

cloth,

dampened

with

water

only,

to

remove

any

fingerprints

or

to

wipe

off

dust.

Clean

the

grille

by

gentle

vacuuming

or

with

a

damp

cloth.

NOTE:

Do

not

use

any

cleaning

products

or

polishes

on

the

cabinet

or

grille.

For

maximum

acoustic

transparency,

the

grille

uses

a

lightweight

structure

that

needs

to

be

handled

with

care

for

removal.

To

remove

the

grille,

gently

pull

on

the

corners

to

unfasten

the

frame

from

the

cabinet.

To

replace

it,

make

sure

to

align

the

frame

pins

first

and

then

gently

snap

the

frame

into

place.

Never

force

the

grille

frame

onto

the

cabinet.

Premature

muting

At

the

moment

the

bass

information

at

the

audio

input

terminals

exceeds

30

mV,

the

amplifier

in

the

Overture

series

switches

from

the

STANDBY

mode

to

the

ON

mode.

Approximately

10

minutes

after

the

bass

information

drops

below

the

sensing

threshold,

the

subwoofer

amplifier

retums

to

STANDBY.

Some

customers

may

experience

a

tendency

for

the

Overture

1,

2

or

3

to

“mute”

or

shut

down

when

played

at

a

low

level

and

negligible

bass

information

is

present.

Actually,

this

is

normal

behavior

for

the

loudspeaker.

/f

the

unit

was

designed

to

be

extremely

sensitive,

the

bass

amplifier

could

sense

small

amounts

of

60

Hz

hum

or

noise

picked

up

by

the

customer's

input

cables,

random

RF

noise,

etc.

and

the

unit

would

never

tum

off.

In

the

event

you

receive

a

Overture

1,

2

or

3

with

the

complaint

“unit

is

shutting

off

(muting)

when

low

levels

of

music

are

being

played”,

this

complaint

can

be

resolved

by

the

replacing

C20

(220uf/25v)

on

the

PCB

with

a

2200uf/25v

capacitor.

This

change

will

lengthen

the

delay

time

for

muting

to

50-60

minutes.

Procedure,

Overture

1:

1)

With

a

sharp

instrument,

carefully

pry

out

and

remove

the

metal

grille

covering

the

woofer,

taking

note

of

the

(4)

rubber

corners

on

the

grille.

2)

Pull

back

the

circular

rubber

flap

and

remove

the

(6)

woofer

mounting

screws

and

their

clamps.

3)

Remove

the

woofer

from

the

cabinet

by

pulling

on

the

rubber

flap,

then

unplug

the

yellow

connecting

wires.

4)

Remove

the

dacron

section

from

the

cabinet.

5)

Outside

the

cabinet,

remove

the

(2)

Phillips

screws

on

the

cabinet

end,

amplifier

side.

6)

Inside

the

cabinet,

remove

the

(2)

amplifier

mounting

nuts.

These

may

be

covered

with

a

sealant

and

will

have

to

be

cleaned

off

before

removal.

7)

Unplug

the

(2)

white

wires

w/spade

terminals

connected

to

the

crossover

assembly.

8)

Remove

the

amplifier

assembly

from

the

cabinet.

9)

Unplug

the

AC

input

wires;

remove

the

transistor

clamp

and

the

two

mounting

nuts

from

the

PCB.

10)

Locate

C20

(See

Figure

1).

Remove

and

replace

with

2200uf/25v

capacitor

(Infinity

part

#

201-8120).

11)

Replace

the

PCB

in

the

heatsink,

taking

care

to

replace

the

insulating

fishpaper

under

the

PCB

and

the

output

transistors.

12)

Re-assemble

and

replace

the

amp

assembly

into

the

cabinet

in

reverse

order,

taking

special

precautions:

a)

There

are

two

gaskets

under

the

woofer

basket,

assure

they

are

both

in

place

upon

re-assembly.

b)

The

(6)

clamps

under

the

woofer

mounting

screws

are

not

symmetrical;

make

sure

the

shorter

side

of

the

clamps

are

pointing

towards

the

center

of

the

woofer

cone.

c)

Tighten

the

(6)

final

woofer

mounting

screws

sequentially;

do

not

over

tighten.

d)

Before

replacing

the

metal

grille,

place

the

rubber

corner(s)

on

each

corner

of

the

grille.

However,

certain

types

disconnect

the

As

the

This

switch

the

Approximately

10

minutes

after

the

noise

disappears,

the

Auto

circuit

will

switch

the

As

the
