Brief description
This is a Class AB mono
audio power amplification module designed with the purpose of being
integrated in Amplified Speakers. It fits inside a square tube made in
aluminiun, where the cooling air enters by one side and goes out through
an holes matrix positioned in one of its faces.
Its main qualifying characteristics are:
+ Low cooling audible noise, despite of its high speed
fan and reduced dissipation volume. This characteristic is due to the
dynamic control over the fan's flow capacity as a function of heat
dissipator´s temperature. This dynamic control impacts very positivelly
in the cooling noise at low audio power levels.
+ The stereo input with integrated mixer and
pré-amplifier with gain control.
design: Paulo Liborio
Involved knowledge areas:
+ Calculation and design in electronics.
+ PCB design and prototypes assembling.
+ Basic mechanical design and assembling.
