An amplifier circuit is depicted, utilizing two TDA2030 integrated circuits as power amplifiers. Additionally, a TT.082 is incorporated to form an active servo circuit for the TDA2030. The circuit features internal protections against overheating, overvoltage, and output short circuits, with fewer peripheral circuit elements for easier alignment. The active servo circuit enhances stability while minimizing distortion. The input section consists of resistors R1, R2 and capacitors C1, C2, which together create a high bass boost circuit. At lower volumes, this configuration is suitable for enhancing both high and low frequencies.

The amplifier circuit is designed to deliver high-quality audio amplification while ensuring reliability through built-in protective features. The use of two TDA2030 integrated circuits allows for significant power output, making it suitable for driving speakers in various audio applications. The TDA2030 is known for its ability to provide efficient amplification with low distortion, which is further enhanced by the active servo circuit implemented with the TT.082. This active servo mechanism continuously monitors the output, adjusting the amplifier's performance to prevent damage from conditions such as overheating and overvoltage, thereby extending the lifespan of the components.

The input stage of the circuit is critical for sound quality, where the resistors (R1 and R2) and capacitors (C1 and C2) form a high bass boost circuit. This configuration allows for the adjustment of frequency response, particularly at lower volume levels, to ensure that both high and low frequencies are adequately enhanced. This capability is particularly beneficial in environments where audio clarity is paramount, such as in home theater systems or public address systems.

Overall, this amplifier circuit is a well-rounded solution for audio amplification needs, combining power, protection, and sound enhancement features in a compact design. The careful selection of components and their arrangement in the circuit provide a robust platform for delivering high-fidelity audio output while maintaining user-friendly operation and maintenance.Amplifier circuit shown in Figure r) 100 shown, with two TDA2030 integrated circuit as a power amplifier; the other with a TT.082 constitute active servo circuit o TDA2030 inte rnal overheat, overvoltage and output short circuit protection, its periphery circuit elements less alignment 1..
