100W Subwoofer Amplifier Circuit Audio Signal is first filtered to remove the high-frequency signals and allow only the low-frequency signals to pass through it. This low-frequency signal is then amplified using a voltage amplifier. This low power signal is then 100W Subwoofer Amplifier using a transistor-driven class AB power amplifier. 100W Subwoofer Amplifier Applications of … Read more
50 Watts MOSFET Amplifier 50-watt power MOSFET Amplifier operates on +35V to -35V range, the input voltage is pre-filtered and pre-amplified before applying to the MOSFET switch. This general audio amplifier is MOSFET, Except for the output power MOSFET, instead, we use J49 and K134, which are more expensive than necessary, We use dual output number J162/K1058, which is Cheap much … Read more
