Dual Audio Amplifier Power Supply Circuit

Description: A dual audio amplifier that delivers 50 W per channel is illustrated in the schematic. It features a preamplifier and tone controls, as well as a headphone amplifier. The circuit also shows a power supply providing 38.5 V and 15 V regulated outputs for the dual 50-watt configuration.

The dual audio amplifier circuit operates with an output power of 50 watts per channel, making it suitable for driving speakers in various audio applications. The preamplifier section is designed to boost low-level audio signals to a level suitable for further amplification. Tone controls allow for the adjustment of bass, midrange, and treble frequencies, enabling users to tailor the sound to their preferences.

The headphone amplifier included in the design ensures that users can listen through headphones without compromising audio quality. This feature is particularly beneficial for personal listening experiences, allowing for a more intimate sound reproduction.

The power supply section is a critical component of this amplifier design, providing the necessary voltage levels for optimal performance. The main supply voltage of 38.5 V is essential for the output stage of the amplifier, ensuring that it can deliver the required power to drive speakers effectively. The additional 15 V regulated output is typically used for powering the preamplifier and tone control circuits, ensuring stable operation and minimizing noise interference.

Overall, this dual audio amplifier schematic represents a well-rounded design that combines power, versatility, and user control, making it suitable for both home audio systems and professional audio applications. A dual audio amplifier that will deliver 50 W per channel is shown in the schematic. It includes preamp and tone controls, and also includes a headphone amplifier. The circuit depicts the power supply that supplies 38.5 V and 15 V regulated for the dual 50 watt.
