Abstract
Nowadays the output of typical car audio player is normally unlikely to generate sufficient power for audio speaker system, so power amplifier must be added to the circuit. The problem is that the technical descriptions and flowcharts usually do not show the crunch capacity and dynamic of amplifier devices. In order to not to blow the amplifier, it is crucial to know the allowed input power, timbre controls and power supply units preventing occurrence of possible power overload. Therefore four-channel (4X100W) power amplifier TK2050 has been selected for this testing purpose. The model of TK2050 electrical components was designed in ISEE Modeling & Simulation Software STELLA dynamically displaying the flow of power, as well as the occurrence of the overload levels depending on the change of input parameters. Following experimenting process led to awareness of input and output relationships in parallel and bridge circuits, element load changes depending on power supply usage, as well as interdependence of input power and EQ settings.
