EVOLUTION SA 3.2
Stereo power amplifier with 2 x 325 Watt
The EVOLUTION SA3.2 stereo power amp in brief:
• High Efficiency switching power amplifier stage with 325 W
• Linear power supply with 700-VA-Transformer
• Filter capacity over 60.000 µF
• Balanced XLR and unbalanced RCA inputs
• 2 pairs of loudspeaker terminals for speakers A & B, individually switchable
• 2 separate power supplies for input section and power output stages.
• Intelligent protection circuits monitor DC, overheat, short circuit
• NF-controlled on/off and trigger input (on/off)
• Comfortable on/off function in conjunction with AVM pre amps
• Environmentally friendly standby power consumption below 1 Watt
• Housing made of solid aluminum anodized in silver or black, chrome front available (option)
A stunning sound quality unheard of in this class combined with enormous power and a reduce-to-the-max
design make heads turn for the SA3.2. Perfectly machined and handcrafted aluminum cases without
visible screws make the SA3.2 an esthetic appearance. The entire massive aluminum housing also serves
as heat sink for the amplifier. Two SA3.2 combined will add up in width to just all other EVOLUTION
components. In height the SA3.2S equals the components of the EVOLUTION 3.2 series, a perfect match
to the PA 3.2 and CD 3.2. Standard finishes are aluminum silver or black anodized; a chrome front may be
supplied as an option.
The highefficiency switching amplifier transforms as much as 95% of the energy delivered from the linear
power supply into music. Dissipating heat it minimal and may almost be neglected. With its huge power
the SA3.2 easily handles all sorts of loudspeakers at all volume levels, even critical speakers with a low
efficiency. A smooth over all feedback loop ensures a high damping factor and by this an excellent control
over the connected loudspeaker.

The powersupply of the SA3.2 is a so-called linear power supply based on a 700VA toroidal transformer
proprietary made for the SA3.2. This powersupply effortlessly supplies the output stages with enough
power, regardless of the level you like to listen to your music. In combination with the PA3.2 or PA5.2 the
SA3.2 may be switched on and off via an intelligent communication system between them. Connected to
preamplifiers of other brands, the SA3.2 may be switched on and off via a 10V trigger switch.
Two pairs of loudspeakers may be connected and switched individually.
Separate power supplies for the input and output stages of the SA3.2 ensure a signal processing and
handling without any loss in fine details. All signal paths are logically arranged and represent the shortest
possible signal path. Switching amplifier output stages drive all speakers available in the market with ease
and extreme control related to the amplifiers high damping factor.
Like all AVM hi-fi components the SA3.2 is carefully developed and assembled by our engineers in
Malsch, Germany. Our vendors for housing and electronic parts reside all near-by. This proximity helps us
to easily ensure and maintain superb quality level of the supplied parts for the AVM hi-fi components
made of these.
During the manufacturing process we perform repeatedly numerous tests to insure the absolute quality of
our products. When the assembling is finished and the first inspection is done all units must pass a run in
test in order to prove their reliability. After that a careful final inspection follows before packing & shipping.
All this ensures creating a perfect product from AVM for our customers.
