Audio pre-amplifier for two satellites and subwoofer
Štaud, Stanislav ; Brančík, Lubomír (referee) ; Kratochvíl, Tomáš (advisor)
The aim of this thesis was to design, simulate and construction audio pre-amplifier for two satellites and subwoofer and monolithic amplifier for subwoofer in the class AB. Audio pre-amplifier provides bass, treble and switch loudness volume control. It includes subsonic filter and active crossovers Sallen-Key with approximation Linkwitz-Riley. There are low noise operating amplifiers LM833 and TL081 at the place of active amplifiers with very low distortion. End-amplifier can delivers power 50 W to 4 ohms. Of consists delayed switch speaker and supports security against direct voltage on the output of amplifier.
