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 fol-
lower. 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.

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.
