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.
