products 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
operational and maintenance
(servicing) instructions in the literature
accompanying the appliance.
CAUTION:
To prevent electric shock do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades

Congratulations on choosing Sonodyne for your professional amplification requirements.
The design of our SMA/SBA Series PA 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 SMA/SBA Series amplifiers are 2 unit (3.5”) high, 19” wide, rack mountable units.
Each channel of SMA250 comprises a balanced active input and an unbalanced input with a buffered
attenuator. All the individual attenuators are then summed and fed to the tone control stage driving a
differential class A drive stage thru a Master control which in turn drives a fan-cooled, class AB, output
stage configured as an emitter follower. SBA250P has a single balanced active input and a balanced active
link output. These amplifiers operate from a Linear power supply source.
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.
