IMPORTANT SAFETY INFORMATION
This operation manual contains important information regarding safety precautions, installation, performance, operation and
maintenance of your Synergy-Series power amplifi er. You should familiarize yourself with the contents of this manual before
operating your amplifi er.
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 amplifi ers 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!
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 fl ow
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 amplifi ers or consoles to any
other voltage source, such as a battery, mains source, or power supply,
regardless of whether the amplifi er or console is turned on or off.
17. Do not run the output of any amplifi er channel back into another
channel’s input. Do not parallel- or series-connect an amplifi er output
with any other amplifi er 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 qualifi ed 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
12. Do not use the unit near stoves, heat registers, radiators, or other heat
producing devices.
THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS MANUAL
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.
INTRODUCTION AND CONTENTS
Congratulations on choosing Australian Monitor for your professional
amplifi cation requirements.
The design of our Synergy-2 Series Audio Power Amplifi ers embraces all the
aspects of a well designed amplifi er. The visual design, mechanical,
electrical and sonic parameters, along with our dedicated manufacturing
process, have all been optimized to provide a professional tool that exhibits
quality, reliability and longevity.
The Synergy-2 Series amplifi ers are 2 unit (3.5”) high, 19” wide, rack
mountable units.
Each channel of the amplifi er comprises a balanced active input with a
buffered attenuator driving a differential class A drive stage which in turn
drives a fan-cooled, classAB, output stage confi gured as an emitter follower. The amplifi er operates from a high current-capable linear
power supply.
These amplifi ers have been specifi cally designed to deliver their high power
output with minimal distortion, and provide the critical degree of control
required by your speakers, at high duty cycles for extended periods.

Caution:
AUS, EUR, USA
Rev 1: August 2006
This symbol is intended to alert the user to the presence
of uninsulated “dangerous voltage” within the products
enclosure that may be of suffi cient magnitude to constitute
a risk of electric shock to persons.
This symbol is intended to alert the user to the presence
of important operational 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.
