Schematic Circuit of 500 Watt Power Amplifier
500-watt power amplifier circuit apex can be used to drive the speakers with impedance of 4 ohms to 32 ohms with a diameter up to 18 inches.
500-watt power amplifier, works with push-pull transistor configuration 4 sets. Transistors are used as final in the 500-watt power amplifier is 2SC5200 and 2SA1943. Image sequence and a list of components to create a 500 watt power amplifier apex shown in the picture.
Forward amplifier 500 watt power amplifier circuit using IC NE5532 as early amplifier audio signal, then the audio signal is divided into two positive and negative sides to amplified separately using the circuit configuration trasistor Q1, Q2, Q3 and Q4. Signal which has been divided into two parts are then amplified respectively using transistor driver MJE15032 and MJE15033 as power amplifier driver.
Amplified signal from the driver for the last time with a push-pull configuration transistore 2SC5200 and 2SA1943 are arranged parallel 4 sets. MJE340 transistor Q5 serves as the base bias voltage control power amplifier.
500 watt power amplifier circuit apex using a DC voltage source ± 90 volts with a current 20A. 500 watt power amplifier circuit must be equipped with a series of speakers protector for procrastinators and DC current detector before being connected to the speakers.
