INSTALLATION AND OPERATION MANUAL

IS SERIES

1. Save the carton and packing material even if the equipment has
arrived in good condition. Should you ever need to ship the unit,
use only the original factory packing.

2. Read all documentation before operating your equipment.
Retain all documentation for future reference.

3. Follow all instructions printed on unit chassis for proper operation.

4. Do not spill water or other liquids into or on the unit, or operate the
unit while standing in liquid.

5. Make sure power outlets conform to the power requirements listed
on the back of the unit.

6. Do not use the unit if the electrical power cord is frayed or broken.
The power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against them,
paying particular attention to cords and plugs, convenience
receptacles, and the point where they exit from the appliance.

7. Always operate the unit with the AC ground wire connected to the
electrical system ground. Precautions should be taken so that the
means of grounding of a piece of equipment is not defeated.

8. Mains voltage must be correct and the same as that printed on the
rear of the unit. Damage caused by connection to improper AC

voltage is not covered by any warranty.

9. Have gain controls on amplifiers turned down during power-up to
prevent speaker damage if there are high signal levels at the
inputs.

10. Power down & disconnect units from mains voltage before making
connections.

11. Never hold a power switch in the “ON” position if it won’t stay
there itself!

12. Do not use the unit near stoves, heat registers, radiators, or other
heat producing devices

13. Do not block fan intake or exhaust ports. Do not operate
equipment on a surface or in an environment which may impede
the normal flow of air around the unit, such as a bed, rug,
weathersheet, carpet, or completely enclosed rack. If the unit
is used in an extremely dusty or smoky environment, the unit
should be periodically “blown free” of foreign matter.

14. Do not remove the cover. Removing the cover will expose you to
potentially dangerous voltages. There are no user serviceable
parts inside.

15. Do not drive the inputs with a signal level greater than that
required to drive equipment to full output.

16. Do not connect the inputs / outputs of amplifiers or consoles to
any other voltage source, such as a battery, mains source, or
power supply, regardless of whether the amplifier or console is
turned on or off.

17. Do not run the output of any amplifier channel back into another
channel’s input. Do not parallel- or series-connect an amplifier
output with any other amplifier output.

Australian Monitor Inc is not responsible for damage to
loudspeakers for any reason.

18. Do not ground any red (“hot”) terminal. Never connect a “hot”
(red) output to ground or to another “hot” (red) output!

19. Non-use periods. The power cord of equipment should be unplugged
from the outlet when left unused for a long period of time.

20. Service Information Equipment should be serviced by qualified
service personnel when:

A. The power supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the

equipment
C. The equipment has been exposed to rain
D. The equipment does not appear to operate normally,

or exhibits a marked change in performance
E. The equipment has been dropped, or the enclosure damaged.

IMPORTANT SAFETY INFORMATION

THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS MANUAL

INTRODUCTION AND CONTENTS

The Australian Monitor Installation Series IS600, IS1200 and IS1600
are 2 RU stereo power amplifiers. The IS600 delivers 300 watts per
channel @ 4 ohms & the IS1200 delivers 600 watts per channel @
4 ohms and the IS1600 delivers 800 watts per channel @ 4 ohms.

Designed for permanent installations where high quality
audioreproduction is required on a small budget, the IS series
deliver the sound quality & features contractors require.

The IS series continues the Australian Monitor tradition of
delivering an amplifier packed with clever features at a
contractor friendly price.

This symbol is intended to alert the user to the presence

of uninsulated “dangerous voltage” within the product’s

enclosure that may be of sufficient magnitude to

constitute a risk of electric shock to persons.

This symbol is intended to alert the user to the presence

of important operation and maintenance (servicing)

instructions in the literature accompanying the appliance.

To prevent electric shock do not use this (polarised) plug

with an extension cord, receptacle or other outlet unless

the blades can be fully inserted to prevent blade exposure.

To prevent electric shock, match wide blade of plug to

wide slot, fully insert.

ATTENUATOR

There are 2 level controls on all IS models.
Each control is labelled for the channel
which it controls. 0dB indicates minimum
attenuation.

CLIP INDICATOR

This LED displays the status of the output
stage and displays two levels of operation.
These levels are:

Below clip level (unlit)
Clipping & above (red)

The LED will change to red once the
output exceeds the clipping point of the
amplifier’s output stage. The threshold is
referred to the amplifier supply rails and
alters with changes in the mains supply,
changes in the load and duty cycle
fluctuations.
The attack and decay time (ballistics) of
the status circuit are those of a Peak
Programme Meter (P.P.M.)

NOTE: The amplifier is not
damaged by running into
clipping, but speakers may be.
To maximise the life of
your speakers, try to keep
clipping infrequent.

POWER SWITCH

This switches AC power to the amplifier.
Press the switch to up for power on and
down for power off. At start-up (turn-on),
the input to the amplifier is muted for
approximately two seconds.

PROTECT INDICATOR

This red LED will illuminate when thermal
shutdown occurs.

ACTIVE INDICATOR

This LED will illuminate blue and indicates
that the amplifier is ON and receiving AC
mains power.

SIGNAL INDICATOR.

This LED displays the status of the output
stage and varies in intensity in proportion
to the output signal level.
