What

sets

FUSION

apart?

The

FUSION

FM

series

amplifiers

come

complete

with

FRAT

power

supplies,

FIST

cooling

system

and

FUTRANZ.

Also

all

marine

amplifiers

use

heat-tempered

PCB's

for

maximum

product

life

and

performance.

Gold

plated

connectology,

ensures

your

signal

flows

from

the

head

unit

through

to

the

speakers

with

as

little

injected

dis-

tortion

and

noise

as

possible.

This

results

is

a

very

clean

and

very

powerful

reproduction

of

the

input

signal.

All

these

features

make

it

easier

to

achieve

sonic

perfection

in

almost

any

installation

.

.FUTRANZ

In

developing

extremely

powerful

amplifiers,

it

is

essential

to

keep

things

cool

so

FUSION

developed

a

heat

sink

that

has

a

heat

dissipation

ability

like

never

before.

This

was

not

an

easy

task

but

none

the

less

it

was

achieved,

another

important

factor

is

efficiently

transferring

the

heat

from

the

semi-conductors

to

the

heat-

sink,

conventional

designs

use

a

white

paste

as

the

interface

between

these

devices

and

the

heatsink,

this

is

not

a

perfect

solution

when

complete

surface

coupling

is

required.

So

all

Marine

Ampliers

come

equipped

with

a

composite

heat

transferring

tape.

Core

heat

in

semi-conductors

causes

distortion

and

poor

component

performance

characteristics.

Testing

has

shown

a

massive

reduction

in

core

heat

has

been

achieved

by

using

the

FUTRANZ

heat

transferring

technology.

In

simplified

terms

this

means

excellent

thermal

stability

and

maximum

component

reliability.

f.I.S.T (FUSION

intercooled

semi-conductor

technology)

FIST

is

an

innovative

method

of

clamping

down

all

internal

power

switching

and

audio

output

devices

with

an

aluminium

extrusion

that

has

extremely

low

temperature

co-efficiency.

By

using

F.I.S.T

it

creates

the

perfect

cooling

solution,

rapidly

removing

core

heat

from

all

associated

semi-conductors

from

both

sides

of

the

device

at

once

resulting

in

extremely

low

distortion

an

excellent

thermal

stability

f.R.A.T (FUSION

intercooled

semi-conductor

technology)

FRAT

is

a

regulated

amplifier

design,

FUSION

regulated

amplifiers

allow

an

enormous

amount

of

output

power

at

the

lowest

voltage

(12.6

Volts)

and

extreme

output

at

14.4

volts.

~

Mounting

~

Appropriate

mounting

is

very

important

for

the

prolonged

life

expectancy

of

any

amplifier.

Select

a

location

that

allows

enough

space

so

sufficient

airflow

is

maintainable

and

a

location

that

provides

protection

from

moisture.

Keep

in

mind

that

an

amplifier

should

never

be

mounted

upside

down.

Upside

down

mounting

will

compromise

heat

dissipation

through

the

heatsink

and

could

engage

the

thermal

protection

circuit.

Excessive

heat

will

shorten

your

amplifiers

life.

To

maximise

heat

dissipation,

be

sure

to

leave

at

least

2.5"

of

clearance

around

the

amplifier.

If

space

is

of

the

essense

and

the

amplifier

must

be

mounted

in

an

enclosed

or

restricted

area,

a

small

3

inch

fan

should

be

used

in

correspondence

with

a

duct

so

the

heat

can

flow

past

the

FUTRANZ

Heatsink.

Try

to

avoid

mounting

any

amplifier

on

a

subwoofer

enclosure,

as

extended

exposure

to

vibration

may

cause

malfunction

of

the

amplifier.

To

avoid

scratching

your

new

FUSION

amplifier,

pre·drill

the

mounting

holes

with

either

a

3mm

or

g/64"

diameter

drill

bit

and

use

the

screws

supplied

in

the

accessory

kit.

Be

sure

to

investigate

your

mounting

area

thoroughly

to

avoid

electrical

wires,

vacuum

lines

and

fuel

lines.

Installation

Options

The

quality

of

installation

will

affect

the

performance

and

reliability

of

your

FUSION

amplifier.

For

maximum

performance

we

recommend

you

have

your

new

FUSION

amplifier

installed

by

an

authorised

FUSION

dealer.

Our

highly

skilled

dealers

have

vast

knowledge

of

our

products

and

their

installation

techniques

are

necessary

to

unleash

the

high

performance

capabilities

of

your

amplifier.

If

you

decide

to

connect

the

amplifier

yourself,

it

is

important

that

you

read

this

manual

carefully

and

throughout

before

starting.

Once

you

have

finished

reading

and

you

still

have

questions

regarding

installation,

we

recommend

your

FUSION

dealer.

Connection

FUSION

amplifiers

are

designed

to

work

within

a10

to

16

volt

DC

range.

Before

any

wires

are

connected,

the

vessel's

electrical

system

should

be

checked

for

correct

voltage

supply

with

the

help

of

a

voltmeter.

First,

check

the

voltage

at

the

battery

with

the

ignition

in

the

OFF

position.

The

voltmeter

should

read

between

12

and

13.8

Volts.

If

your

vessel's

electrical

system

is

not

up

to

these

specification,

we

recommend

having

it

checked

by

an

auto

electrician

before

any

further

installation.

Once

the

vessel

is

checked,

make

certain

the

correct

cable

size

is

used.

We

recommend

using

the

following

cables

calculator

diagram

on

page

8

to

calculate

the

correct

power

cable

for

your

application.

Power

FUSION

amplifiers

should

be

wired

directly

to

the

battery

using

the

appropriate

sized

cable.

Start

at

the

vessel

battery

and

run

the

power

cable

through

to

the

amplifier.

FUSION

recommends

the

use

of

grommets

when

passing

the

power

cable

through

any

metal

wall

to

avoid

sharp

corners

or

panels

that

may

easily

cut

through

the

insulation

on

the

cable.

Avoid

running

the

power

cable

over

engine

components.

The

use

of

an

inline

fuse

or

circuit

breaker

is

a

must,

this

will

pre-

vent

the

risk

of

a

potential

fire

caused

be

a

short

in

your

power

cable.

Connect

the

fuse

holder

or

circuit

breaker

as

close

to

the

battery

positive

terminal

as

possible.

Use

a

fuse

or

circuit

breaker

of

equal

value

as

that

found

on

the

chassis

of

your

FUSION

amplifier.

You

may

now

connect

the

cable

to

the

battery,

but

remember

to

leave

the

fuse

out

or

circuit

breaker

off

until

all

other

cable

connections

are

made.

Ground

When

grounding

your

FUSION

amplifier,

locate

a

metal

area

close

to

the

amplifier

that

is

a

good

source

of

ground.

Once

again,

investigate

the

area

you

wish

to

use

for

electrical

wires,

vacuum

lines,

and

fuel

lines.

Use

either

a

wire

brush

or

sandpaper

to

eliminate

unwanted

paint.

This

will

supply

a

better

contact

for

your

ground.

Use

the

same

gauge

cable

for

ground

as

you

did

for

the

power.

Secure

the

ground

cable

to

the

appropriate

ground

point

using

a

bolt.

star

washer

and

nut.

Spread

silicon

over

the

screw

and

bare

metal

to

prevent

rust.

Now

its

time

to

connect

the

power

and

ground

cables

to

the

amplifier.

Cut

both

cables

to

length.

Crimp

the

yellow

spade

connectors

supplied

to

the

power

and

ground.

Use

a

hex

type

screwdriver

to

loosen

the

+

12V

and

the

GND

connections

on

the

amplifier.

Terminate

the

ground

first,

and

then

the

+

12V

and

please

make

sure

that

you

terminate

them

into

the

correct

terminals.

Then

tighten

the

screws

down

securely.

Speaker

Load

Keep

in

mind

FUSION

'FM'

series

amplifiers

are

high

power

amplifiers

and

not

high

current

amplifiers.

In

other

words

they

require

a

minimum

impedance

of

2

ohms

STEREO

and

4

ohms

bridged

MONO

to

operate

trouble

free.

Too

low

of

an

impedance

could

send

your

FUSION

amplifier

into

protection

mode

and/or

damage

the

amplifier.

Remote

Turn-on

This

terminal

must

be

connected

to

a

switched

+

12V

source.

Typically,

remote

turn-on

leads

are

provided

at

the

head

unit

which

will

turn

on

and

off

the

amplifier

in

correspondence

with

the

source.

If

the

head

unit

does

not

have

a

remote

turn-on

lead,

then

a

power

antenna

wire

can

be

used.

If

neither

of

these

leads

are

present

on

the

head

unit

then

a

switched

+

12V

supply

must

be

used

,

like

the

ACC

+

12V.

Run

a

minimum

of

18

gauge

wire

from

the

amplifier

location

to

the

source

of

the

switched

+

12V

lead.

If

possible,

route

this

wire

on

the

same

side

of

the

vessel

as

your

power

cable.

Connect

the

source

remote

output

to

the

wire.

Go

back

to

the

amplifier

and

cut

the

wire

to

length.

Loosen

the

screw

terminal

marked

REM

on

the

amplifier

using

a

hex

type

screwdriver.

Slip

the

wire

into

the

connector

and

tighten

the

screw

securely.

Speaker

Wiring

Choose

the

correct

speaker

wire

for

your

application.

Most

application

will

require

a

minimum

of

16

gauge.

Route

these

using

the

same

precautions

as

you

did

when

you

ran

the

power

cables.

Terminate

these

wires

at

the

speaker

end

using

insulated

speaker

terminals

(not

supplied)

or

by

soldering

the

connection.

Make

sure

the

speaker

connections

are

positive

to

positive

and

negative

to

negative

.

At

the

amplifier

end,

use

a

#2

Phillips

screwdriver

to

loosen

the

speaker

terminals

on

the

amplifier.

Connect

the

speaker

wires

and

tighten

the

screws

securely.

Check

to

make

sure

you've

maintained

proper
