This is 1000W Power Audio Amplifier Circuit built with transistors, from the pre-amp amplifier to the final transistors stage. This amplifier circuit design for single channel. But if you want stereo audio system, you can build two same circuit.
This 1000W Power Audio Amplifier Circuit is an amplifier designed with the OCL (Output Capacitor Less) system, so that the output does not use decoupling capacitors. the advantage of this system is the output will produce a better frequency response especially for the low frequency response.
1000W power audio amplifier circuit diagram
In order for this audio amplifier circuit can operate properly, it takes at least a power supply with a current of 10A for one channel, and 20A for two-channel (stereo). Source voltage of the power supply required is symmetrical with power supply voltage 63VDC.
1000W power audio amplifier circuit component list:
Transistors 2SA1216 and 2SC2922 final level must use the heatsink so that heat can be channeled properly when working optimally. Use heatsink will also prevent the circuit from overheating which can result in damage to the amplifier circuit.
1000W power audio amplifier circuit loudspeaker combination
To get the speaker output with optimal power, you can combine several loudspeakers arranged in series-parallel. But keep in mind all the loudspeaker, either the woofer, middle and twitter should have the same impedance.
When trying this audio amplifier circuit, make sure the input signal is connected to the ground in advance or pre-amp section volume in the lowest position.
