Stage sound manufacturer
★ precision two-stage AB type is adopted in the circuit.
★ delayed startup "soft start" function, closed-loop controlled peak limiter, soft start, overheating protection and short-circuit protection; It has perfect protection circuits for short circuit / overcurrent, overvoltage, overtemperature and amplitude limiting.
★ in terms of power supply, class a iron core of transformer and oxygen free copper enamelled wire are used to make the energy more sufficient and the working temperature lower.
★ the power filter capacitor adopts special audio capacitor, which has less distortion, lower internal resistance, faster and stronger charge and discharge current.
★ the front panel is equipped with power indicator, protection lamp, signal lamp and clipping lamp to display the current working state of the equipment.
★ it adopts fluid mechanics design, reasonable natural air cooling and forced air cooling, ultra silent operation, and can work in a relatively harsh environment.
★ the installation method adopts the standard 19 inch rack width and 2U 9-inch chassis design.
