Hall Professional Amplifier V400

Features:

V-Series professional amplifiers are high-performance, high-efficiency and high-quality amplifiers in VESIT electronic products. In order to obtain the most beautiful sound, the power amplifier adopts the famous Toshiba high-power metal power amplifier tube; the cooling system adopts high-efficiency stepless speed change, so that the power amplifier can achieve the best protection under effective working conditions:

1. Soft start protection: It can effectively buffer the high current impact generated at the moment of starting up;

2. Overheating protection: when the temperature generated by the power amplifier exceeds 90 degrees, it can automatically cut off the connection between the speakers to ensure that the speaker system can be protected.

3. Excellent short-circuit protection: it can avoid equipment damage caused by misoperation during engineering use;

4. Mute protection: It can eliminate the impact on the speaker at the moment of machine startup and shutdown, and protect the speaker;

5. DC protection: When the power amplifier is in an abnormal working state, it will automatically cut off the connection between the power amplifier and the speakers to protect the expensive speakers, and more importantly, it can make the power amplifier work easily in harsh environments.

6. Limiting protection: When a square wave appears in the output signal of the power amplifier, the working state of the power amplifier circuit will be adjusted immediately to eliminate the square wave and protect the speaker.

8. The power amplifier has excellent signal conversion characteristics. It has very small harmonic distortion (THD), intermodulation distortion (SMOTE-IM), instant intermodulation distortion, pure, natural and natural sound quality to interpret the perfect music.
