Hrdina, Robin ; Kledrowetz, Vilém (referee) ; Šteffan, Pavel (advisor)
This bachelor thesis describes the design and construction of a one-channel amplifier 200 W into 8 load for an active subwoofer. The design consists of an active correction preamplifier and output stage. Preamplifier is created of integrated operational amplifiers and is controlled by two potentiometers, input switch and phase switch. Output stage is created of integrated circuits LM3886T by Texas Instruments. Both stages were constructed on PCBs and were measured their parameters.
