1500W HiFi Power Amplifier Circuit

Circuit Power Amplifier has a power output of up to 1500W RMS, power amplifier circuit is often used to power sound systems needed to outdor. In a circuit of images can be seen the final power amplifier uses 10 sets of large power transistors for the ending.

This power amplifier circuit using a transistor amplifier starting from the front, signal splitter, driver and power amplifier. Current consumption required is quite large power amplifier that is 15-20 A for this 1500W power amplifier circuit. Supply voltage needed by the power amplifier in order to work optimally is symmetrical 130VDC (130VDC ground-+130 VDC). 1500W amplifier circuit below is a picture circuit of mono, if you want to create a stereo it is necessary to make 2 copies of the circuit. For more details can be viewed directly image following a circuit 1500W power amplifier.

1500W HiFi Power Amplifier Circuit

In the above circuit 1500W power amplifer has been equipped to control the DC Offset function to set the power amplifier when turned on and no input signal then the output should 0VDC. Then it is also equipped with a bias flow regulator to the power amplifier. The final power amplifier section requires that sufficient coolant to absorb heat generated. Power amplifier is not equipped with speakers protectors, therefore it should diapsang speaker protector on the output for when the power amplifier is turned on does not happen the beat to the speakers that may damage the speaker.

  1. Good morning and a wonderful day,I tried the circuit once but it didn't work,, output was never zero ,so I left it . please some has built it recently pls I need thief contacts . I make and design boards so I don't have problems with the board. Thanks

    1. it so nice one you can try 2800W amplifier

    2. difficult to built this amplifier
