Explanation of 450W Amplifier Circuit 2SC2922 & 2SA1216

The 2SC2922 and 2SA1216 Sanken transistors are high-quality transistors that are commonly used in power amplifiers. These transistors are known for their reliability and excellent performance in high power applications. The 2SC2922 is a PNP transistor, while the 2SA1216 is an NPN transistor. When used together in a power amplifier circuit, they provide a powerful output with low distortion.

In the power supply circuit, it is important to have accurate voltage regulation to ensure stable and consistent power delivery to the amplifier. This is achieved by using electrolytic capacitors with a voltage rating of 80V or higher and a capacitance of 20000uF or higher. These capacitors help to prevent voltage drops when the amplifier is operating at high bass levels. Additionally, a diode bridge with a minimum rating of 35A is used to regulate the current input voltage.

Moving on to the buffer circuit, PNP transistors such as a pair of 2SA1266 is used along with an NPN transistor MJE340. These transistors help to amplify and buffer the input signal before it is passed onto the driver circuit.

The driver circuit utilizes PNP transistors MJE340 and NPN transistors MJE350 to further amplify the signal from the buffer circuit and prepare it for the amplifier output stage.

Finally, the output amplifier circuit uses two sets of 2SC2922 and 2SA1216 transistors. This configuration allows for a high-power output of 450 watts mono. The use of Sanken transistors in the amplifier output stage ensures that the sound output is of the highest quality, with minimal distortion.

Conclusion

In conclusion, the 450W power amplifier circuit using 2SC2922 and 2SA1216 Sanken transistors is a powerful and reliable solution for high-power audio applications. The use of quality transistors and accurate power supply circuitry ensures that the sound output is of the highest quality, with low distortion. Whether used for events, field applications, or closed environments, this amplifier is suitable for driving various types of speakers, including woofers, full-range speakers, and subwoofers.
