XB series power amplifier enjoys a stable and reliable circuit design, beautiful whole structure. And excellent fine cooling system provides overheating and overload protection, output DC potential protection, ON OFF striking resistant current circuit design, temperature control electrodeless high speed air cooling heat dissipation. Power amplifier adopts the classic Toshiba large power amplifier tube, military-grade large-capacity electrolytic capacitors for current reserve. Output DC voltage protection and self-locking (avoiding damage to the speaker causing by repetitive relay turning on and off under critical state of protection). Overload distortionless compress and limit (when the circuit detects an output overload, it will automatically compress the power amplifier to keep signal output never distorted). Temperature protection, power on delay and temperature control electrodeless speed regulating air cooling heat dissipation.
Application: XB series are applied to multi-functional dancing halls, KTV clubs, theaters and other occasions.
