    VB series Four channel professional amplifier

    Model:VB2004、VB4004

    Suitable for mass selling KTVs, bars, nightclubs, multi-functional halls and other engineering series. The sensitive overheat management system of this series of amplifiers adopts a unique circuit for real-time monitoring to adjust the temperature of the amplifiers. When it endangers product use, the circuit does not need to be closed and the output power is reduced. When external factors are eliminated, the equipment automatically recovers, ensuring that it can work normally in high temperature and harsh environments. This machine is equipped with a fully intelligent protection system, which ensures the stable and reliable operation of the sound reinforcement system, ensuring the smooth and peaceful progress of the entire performance project.

    Description

    ★ The appearance is simple and beautiful, the overall structure is safe and firm, and it has a professional and technological image of high-end products.
    ★ The entire machine is equipped with multiple sets of high-capacity DC power supply systems, ensuring stable DC power supply voltage and strong power amplifier thrust ability. All components are carefully selected, matched, and crafted to ensure dynamic sound, clear hierarchy, wide sound field, and sweet sound quality.
    ★ The entire machine generally uses SMD components with the shortest circuit transmission distance, eliminating interference, improving audio performance, and greatly reducing manual intervention, ensuring better product reliability and long-term stability.
    ★ The power supply part of the entire machine is equipped with excellent factor correction regardless of cost, completely eliminating harmful harmonic currents and meeting the power factor requirements of electrical appliances in Europe and America.
