PA Power Amplifier 2000W

● Standard 19-inch rack design, black aluminum brushed panel, laser cutting chassis, professional appearance and high grade;

● In order to save installation space and better heat dissipation design, the device has built-in 4 independent power amplifier modules, independent input and output, and each channel has a separate volume adjustment;

● 4-channel 6.35 input, supporting large two-core unbalanced input and large three-core balanced input;

● 3-segment LED level indicator: can display output signal strength, distortion status, protection, and easy to observe the working condition of the machine;

● Adopting the most advanced transformer design in the industry, the power amplifier output is cut off when the internal temperature of the transformer exceeds 105 degrees, which better plays an overload protection role;

● Adopting imported power tubes, the output power is strong; wide bandwidth, low noise, high fidelity, perfect restoration of human voice and music;

● Comprehensive protection circuit: DC protection, if there is a DC voltage at the output end of the power amplifier, the output is cut off immediately to protect the speaker; short circuit protection: if the load is short-circuited, the output is cut off immediately, and the fault is automatically restored; thermal protection, if the temperature inside the power amplifier exceeds 70℃, the power control is started; if it exceeds 85℃, the power amplifier is turned off;

● Independent soft-start protection circuit to prevent damage to the equipment caused by high current at startup;

● Professional voltage limiting circuit can detect output signal clipping caused by various situations such as reduced power supply voltage, heavy load, excessive input signal, and increased amplifier temperature, and automatically correct it to avoid output signal distortion, resulting in broken sound, and damage to the amplifier and speaker;

● Tunnel-type air duct, forced air cooling from front to back, with intelligent fan speed management function, low speed operation at room temperature, the fan speed increases when the temperature in the amplifier exceeds 70℃, and the power control is started. When it reaches 90 degrees, the fan rotates at full speed and cuts off the amplifier output, and the temperature indicator light is lit to alarm abnormally;

● Professional modular circuit design to ensure reliable consistency of the product.

● High-strength 1.5MM thickened body to ensure that the product will not be deformed due to harsh transportation environment;
