600W subwoofer audio amplifier with 20 channel mixer and parametric

This picture below is about my setup subwoofer amplifier with 20 CH mixer and parametric. This amplifier use transformer 10 ampere to supply the power and 3 ampere transformer use to supply mixer and parametric.Elco capacitor that i use for the transformer 10 A, only 10000uF numbered 2. The circuit of amplifiers that i use which is 600 watt mono subwoofer amplifier . And booster amplifier only use 2 Sanken transistors. See picture subwoofer amplifier assemblies below :

Inverter Circuit 12VDC to 220V 50Hz 500W

This is circuit Inverter 12VDC to 220V 50Hz 500W.
It easy to make and Low cost. Friends favorite circuit about the the inverter, because like working outdoors, or to backup storage to use when necessary. Most of this is circuit low power, which is not suitable for practical applications. My friends said that he would be about 500 Watt.

It is a good size. Use with television receivers and light bulbs as well. When looking for circuit. I get headaches. If you are a beginner or I can not buy expensive good quality circuits. Requires only one transistor. Or if you have free time. I want to build old circuit is alive again. This circuit will accommodate all your needs. It is a simple circuit. 

Inverter 12VDC to 220V 50Hz 500W
Inverter 12VDC to 220V 50Hz 500W

The same principle, I take battery voltage 12V to produce a oscillator about 100 Hz and pass to a two frequency divider circuit is only 50HZ. And drive a 10 ampere transformer with 10 x 2N3055 transistor in parallel. By a single transistor has 2A, when I use 10 transistors or 5 pairs of drive high current output. The complexity of circuit, but the principle is not it, and it is the number of transistors on a basic, easy to buy. You may be modified 100 watt power inverter To the size of transistors and transformers as well.

High and quality audio power amplifier with MJ15024G and MJ15025G

Spesification of this amplifier is high enough , and require a lot of expense to make this super-power amplifier. In the transformer using 20A and manufactered / branded ERA , ERA trafo is one of the best transformer , in addition to the power amplifier as well as power supply adapter , regulator , stabilizer , charger , etc. Because copper is intact , a strong iron and did not issue a frequency so that when the amplifier is turned on , output sound amplifier no buzzing. So if you in choosing a transformer , do not hesitate to use the transformer branded ERA.

Above and below the picture is the end of the amplifier circuit, so-called booster amplifier. Picture above using 14 pairs of transistor MJ15025G and his partner MJ15024G . Transistor price range of $5 - $6 , has power output of 250W on each transistor , for more details , see datasheet of each transistor.

Installed transistor with resistor but still a mess
Transistors MJ5025G and MJ15024G very fith with power amplifier 300 Watt subwoofer , 450 Watt , 600W , 750 Watt , 1050 Watt , 1200 Watt , and higher. The buffer and its driver using transistor not ic. For power schematic diagram can be found here.

3000W Stereo 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 keperlun for outdor. In the final image can be seen a series of power amplifiers using 10 sets of power transistors for the ending.

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

In the above series of power amplifer 1500W is equipped to control a DC Offset function to set the power amplifier is turned on at the moment and with no input signal then the output should be 0VDC. Then also equipped with a flow regulator to the power amplifier bias. Final part of this power amplifier requires adequate cooling to absorb the heat generated. Power amplifier is not equipped with a speaker protector, therefore it is necessary diapsang protector on the speaker output so that when the power amplifier is not the case turned on the beat to the speaker that can damage the speaker.
