IMPORTANT SAFETY INFORMATION
This operation manual contains important information regarding safety precautions, installation, performance, operation and maintenance of your Synergy-Series power amplifier. You should familiarize yourself with the contents of this manual before operating your amplifier.
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.
10Power 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 parallelor 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.
THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS MANUAL

The design of our Synergy-2 Series Audio Power Amplifiers embraces all the aspects of a well designed amplifier. 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 amplifiers are 2 unit (3.5”) high, 19” wide, rack mountable units.
Each channel of the amplifier 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 configured as an emitter follower. The amplifier operates from a high current-capable linear
power supply.
These amplifiers have been specifically 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.
