Class AB audio amplifier for two satellites and subwoofer
Cupák, Jan ; Brančík, Lubomír (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor’s thesis deals with design of AB class audio amplifiers. Further more it deals also with other functional blocks, e.g. preamplifier, tone equalizer and active crossover. Outcome of this work is a complete solution of the amplifier with it's simulation. In final solution is also included scheme of a high quality power supply unit, speaker protection and heat sinks for high performance transistors. In this project is also included a solution of task about optimal mechanical arrangement of the single parts in the case of this amplifier. This thesis contains results of measurement and photo document of functional prototype.

Class D audio amplifier for active loudspeakers
Cupák, Jan ; Punčochář, Josef (referee) ; Kratochvíl, Tomáš (advisor)
This master's thesis deals with design of D class audio final amplifier, which was output power 400 W for 4 ? load impedance. Designed audio amplifier is specifical for active speaker, which consists of satelite speakers and subwoofer. Further more it deals also with other functional blocks, e.g. balanced input preamplifier, active crossover and protection for safety running. Outcome of this work are schemes of each functional blocks of D class audio amplifier, whose functionality was verified by simulation. Thesis also contains full reference material including mechanical arrangement of functional blocks on printed connection board. The conclusion contains the measured parameters of function blocks of produced prototype and complete photographic documentation.
