Professional speakers have two types of outputs identified as high and low level. The high-level outputs are used for the main speakers since they amplify the left and right speakers. Generally, the ...

Here we designed a power amplifier circuit using push pull class AB configuration to derive a power of 150W to drive a load of 8 Ohms (speaker). Here we designed a power amplifier circuit using push ...

This simple mosfet power audio amplifier circuit, with TL071C and 2 MOSFETs (IRF9530 and IRF530) can deliver up to 45W on 8Ω speaker or 70W on 4Ω speaker. This schematic is based on Siliconix ...
