How to Create 1000 Watt Power Amplifier

Power amplifier has up to 1000 Watt power, this circuit made one channel only so if you want to create a stereo in it must be made one again, actually this is more suitable power amplifier in use for Sound System or outdoor, so if only in use for the house I think is less suitable.
Maybe you've seen or even have an active speaker and there is written 1500 watts PM PO (Peak Music Power Output), make no mistake this is different from Power Amplifier Active Speaker, I often dismantle such Active Speaker in it only a power with power no more than 150 watts by using the transformer 2-3 Ampere. PM PO is not a real power which is issued by the Power Amplifier, but counting all the speakers that there is, for example: if there are 5 pieces of speakers on each channel and each speaker has a power of 10 W then it is 100 W PM PO.

While this 1000 Watt Power Amplifier minimal use transformer 20 Ampere. And the output of Power Amplifier DC voltage contains approximately 63 volts, with currents and voltages of this magnitude, this 1000 Watt Power Amplifier will not hesitate hesitate to destroy your woofer speakers to connect. To overcome that then before the speaker on connects to 1000 Watt Power Amplifier must be in pairs Speaker Protector.

Actually if you want to create a Power Amplifier with great power does not have to make a Power Amplifier with great power. Example: you want to create a Power Amplifier with 10,000 Watt power. You do not have to assemble a Power Amplifier with power of 10,000 watts, but you assemble the power Power Amplifier Small but many, such as you assemble the Power Amplifier with 1000 Watts of power for as many as 10 pieces, it will produce 10 000 Watt Power Amplifier helpless.

Circuit uses power transistors pair of 5 x 5 x 2SA1216 and 2SC2922 and 2SC1583 use a differential amplifier that actually contains 2 pieces of transistors that are in containers together. see Booster Amplifier Circuit Why use such built-in amplifier differential so identical / similar, could have uses 2 separate transistors but can result in amplifier so it is not symmetrical.

Tips combining speaker.

To get the speakers with great power combining techniques can be used in parallel series, combining each group of speakers should speaker they will have the same impedance, the same type (Woofer, Mid Range or tweeter) and the same power. Number of merging these speakers should consists of 4 , 9, 16 ff, see picture

Speaker wiring

Example: The number of speakers have 4 pieces each of its 200 Watt power generated will be a speaker at = 200 x 4 = 800 Watt. If there are 9 speakers 200 W then the result = 9 x 200 W = 1800 Watt.

Can i use 2SC5200 and 2SA1943 for final transistor?

yes you can use it, but it affect for power output amplifier

Do you have a PCB layout file for this?

its ocl mode amplifier class ab.

i dont have the pcb layout design for this amplifier.

i never know the use of adobe shadow until i saw this post. thank you for this! this is very helpful.

What Is in put power supply means (In put dc current(what AMP and input dc voltage) this circuits diagram)

Please told me what is dc power supply circuits are used and what Watts/Ampere transformer are use in system.....and please shared this link.....

Great Article! Nice information you shared about how to create 1000 Watt Power Amplifier it is so helpful to me. Keep sharing.
