2800W High Power Amplifier Circuit [Updated!]

Mono high power amplifier circuit is actually powerful, output about 1400 W, but if this high power amplifier circuit is doubled and you want to create stereo power amplifier, this high power amplifier circuit the necessary components and PCB requires two-fold. So if the stereo high power amplifier 2 X 1400W Power Output ( 2800W ).

Power Amplifier Circuit Diagram is still less by looking at the circuit that was so below, the finished circuit has been added with gains, using two JRC4558 IC  the picture IC where it can be seen below. For circuit buffers, drivers, and booster use multiple transistors and other components (can be seen listed component). And high power amplifier project that is so below is just part of the buffer and driver while the booster has not been made. For additional transistors in the booster or high power amplifier, end scheme can be found Booster output power amplifier. For bass booster using this circuit:

1600W Power Amplifier + Speaker Protector

Power amplifier with high power output that is greatly needed by many audiophiles. Especially for field or concert, and in addition to the SPL car audio designation. Eg for controlling the use of extreme subwoofer speakers. So it takes a lot of power.

And the following is a power amplifier circuit that can generate output power up to 1600Watt at 4Ohm speaker load. In addition to having a large power, the power amplifier is already equipped with the protection of speakers. The function of the protection speakers is that the speakers are protected by DC voltage which can damage the speakers. It also can cut off the output current when the circuit occurs, so the power amplifier circuit remains safe.

Back to the discussion of this power amplifier. This power amplifier uses 4 final sets of 2SC3264 and 2SA1295 transistors. Where each transistor can flow current up to 18A and has power 200W.

To get a large power, the role of power supply amplifier is very important. Power supply for this amplifier at least 20A with max voltage 100V.
