### DESCRIPTION

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.
