OWNERS MANUAL

Congratulations

on

your

choice of the Australian

designed

and manufactured,

Australian

Monitor

range

of

Power

Amplifrers.

The

AM1600

and

AM1000

MOSFET

Power Amplifiers

have

been

designed for

professional

applications.

They

are

therefore built

to work

within

their

designed

specifications,

over

extended

periods

and with

total

reliability.

Certain

conventions

are used in

this

Manual

to ease understanding.

A

description

of

where

to find

a

feature

is

sometimes

written in'italics

'

and

inside

brackets'(

)'immediately

after the feature

is first mentioned.

(See'switching

On'

for

an example).

When we refer

to a

particular

control

or

function,

as

it is

actually

labelled

on the

amplifier, we have

used

all CAPITAL letters.

So

if

when

we explain how

the input

attenuators

work, we

will

print

Input

ATTENUATORs.

If

a

feature

is not labelled

on

the amplifier

then we

will only

print

the first letters

in

capitals.

The

Australian

Monitor

AM1600and

AM1000

may

be

mounted

into

a

rack

by

using

only the Front

Rack

Ears.

It is recommended

that

both front

and back

panel

mounts

be used

when

using the

amplifier in

a touring

environment. If having

a

case

built to house

the

amplifier,

the

rack

mounting

points

are

situated

368

millimetres

apart,

(from

behind front

panel

to back

panel).

The

amplifrers

should

only be

used

in

the

horizontal

position

on a

level

and stable

surface.

The

speaker

cable runs

should be

as short as

possible,

of

a

high

quality

and

with

the

maximum

available

cross section.

(i.e

the higher

the current rating

the better)

Make

sure the

amplifrer is

ensured

an uninterupted

air flow

through its

Front

and

Back

Vents.

Check

that

the

local

mains

supply is

the same Voltage

labelled

on

the

Back

Panel

of

the amplifier.

Before

switching

on, always

turn

both

input'AT'TENUATORs'to

the'OFF"

position

(fully

counter-clockwise).

(The

attenuators

are located

on the

front

panel.)

To

turn

the

amplifrer

on,

you push

down

the

large

black

switch labelled'POWER'

(this

switch

is located

centrally

on

thc

front

parcl).The

LED

above the

switch

may

momentarily

flash

red

in

colour

(indicating

the correct

operation

of the

Mains

Inrush

Suppression

circuitry).

lF

It is

also recommended

that

your

speakers should

be

connected

before

switching

on unit. If

something

seems

wrongyou

should

then disconnect

the

speakers

from

the

amplifier

and

try switching

on again.
