Introduction to professional power amplifier application scenarios and features
The XL-350 and XL-550 are ideal for home theaters, conference rooms and restaurants.
The circuit handles very high frequencies and is suitable for the sound of conference rooms and the music output of restaurants. And professional power amplifiers are relatively small in size and easy to carry and transport.
◆ Cooling system
The professional power amplifier uses a continuously variable speed fan and a T-type radiator. The power tube is directly mounted on the radiator. Using the principle of wind dynamics, the heat dissipation is fast, and the power is operated at the most suitable temperature.
◆ Protection
Full range of fully equipped protection circuits: DC, short circuit, overvoltage and overcurrent protection, soft start, power amplifier tube overheat protection, distortion limit.
❈ Product Details
part.1
The circuit board, power tube and heat sink are closely attached to double the heat dissipation effect, maintaining the most suitable operating temperature and improving the stability of the power output. It is equipped with two stepless speed-regulated cooling fans to ensure that the entire machine is operating at optimum temperature.
part.2
High purity oxygen free copper cycle transformer. Really high power, true high fidelity. Low temperature, long life and strong anti-magnetic interference. Ensure adequate power output.
part.3
The XL series professional power amplifiers use Class AB circuits to increase output efficiency and reduce losses. The American Anson power tube is designed with a full board, which greatly reduces the wiring connection. Use advanced placement technology to provide better electrical performance and reduce failure rates. Four 100V 4700μF and multiple aluminum electrolytic chip capacitors are used to extend the working life of the circuit.
