The circuit incorporates an on board power supply; therefore, only centre tapped transformer is required to power the circuit. It has very good quality sound. More: You can use it with your Home Theatre, your PC, etc. You can also use it as a Subwoofer Amplifier. It is a compact package for THIN-TYPE audio sets. Easy heatsink design to disperse heat generated in THIN-TYPE audio sets. Constant-Current circuit to reduce supply switch-ON and switch-OFF shock noise. External supply switch-On and switch-OFF shock noise muting, load short-circuit protection, thermal shutdown and other circuits can be tailored-designed.

The audio power amplifier described utilizes the STK4050 hybrid integrated circuit, which is renowned for its low noise characteristics and high fidelity audio output. The design supports a maximum output power of 200W, making it suitable for various applications, including home theater systems and personal computers.

The amplifier features an integrated power supply, simplifying the setup process by requiring only a center-tapped transformer. This design choice not only reduces component count but also enhances reliability by minimizing external connections. The compact nature of the circuit allows it to fit into thin-type audio setups, addressing the trend for space-saving electronics.

An essential aspect of the design is the incorporation of a volume control, enabling users to adjust audio levels according to their preferences. The amplifier's performance is optimized for high-quality sound reproduction, making it an excellent choice for both casual listeners and audiophiles.

Thermal management is addressed through an easy heatsink design, which effectively dissipates heat generated during operation. This is particularly important in thin-type audio sets, where space constraints can lead to overheating issues. The constant-current circuit design further contributes to sound quality by reducing switch-on and switch-off shock noise, which can be disruptive in audio applications.

Additional features include external supply switch-on and switch-off shock noise muting, load short-circuit protection, and thermal shutdown mechanisms. These safety features ensure that the amplifier operates reliably under varying conditions, protecting both the circuit itself and any connected audio equipment. Furthermore, the design allows for customization, enabling engineers to tailor specific circuits to meet unique application requirements. Overall, this mono audio power amplifier presents a robust solution for high-quality audio amplification in a variety of settings.This complete high quality, low noise mono audio power amplifier is based around the Hybrid Integrated Circuit STK4050 manufactured by Sanyo.
