Subwoofer Amplifier Circuit Diagram Pdf. Klipsch subwoofer amplifier service manual ksamm 002a other features this amplifier uses a control circuit to control the operation of the output relay. Designed and organized crutchfield s subwoofer wiring diagrams.
Circuit diagram with parts list. In this project we are going to design a subwoofer amplifier circuit using ic tda2030 with few cheap components. Tda2030 subwoofer amplifier circuit diagrams pdf continue the amplifier tda2030 scheme based on lm1875 tda2040 can be used instead of tda2030 tda2050 pcb design a fairly small amount of control potentiometer attached to the capator power filter on the pcb can be used with a different bass filter amplifier.
In this circuit we can use 10 transistors.
The cut off frequency was assumed to be 200hz and the quality factor is assumed to be 0 707. When power is first applied the circuit provides a delay before activating the relay. The cut off frequency was assumed to be 200hz and the quality factor is assumed to be 0 707. This subwoofer amplifier circuit consists of a tl072 low noise jfet dual operational amplifier ic1 and two lm1875 ic2 and ic3 power amplifiers.
