1000W Power Audio Amplifier


is 1000W power amplifier circuit built using many power transistors.
The following scheme diagram is used for single/mono channel only, you
may build two same circuit for stereo audio system.

1000W Power Audio Amplifier Circuit Design

The power supply needed for this circuit should be 10A minimum single
channel and 20A for stereo channel. It uses symmetrical power supply
(dual polarity) with recommended voltage is 63V.

Component List:

1000W Power Audio Amplifier Part List

The power transistors 2SA1216 and 2SC2922 must be mounted on heatsink
to prevent overheating which will affect to the sound performance and
make the transistors damaged faster than normal condition.

Loudspeaker Combination:

Loudspeaker combination

To get the speakers with great power combining techniques can be used
in parallel series, combining each group of speakers should sepaker
they will have the same impedance, the same type (Woofer, Mid Range or
tweeter) and the same power. Make sure the volume level adjusted in
lowest position when make a trial of this 1000w power audio amplifier.
