TDH300

300W professional amplifier

300W professional amplifier


•Aluminum panel, novel appearance design, standard 2U chassis height, suitable for cabinet installation. High-strength structural chassis, symmetrical structure with the rack, fast assembly; •Adopts high-efficiency large-scale transformer and large-capacity capacitor filter power supply to achieve low distortion when the power amplifier outputs at full load, stronger low-frequency control, and clearer sound; •Precise gain control on the front panel, with working status signal lights for power, signal, protection and clipping; •Fully automatic protection circuit design for each channel to protect DC, overheating, overload, and amplitude limiting; •Automatic variable frequency cooling fan, the greater the power used, the higher the speed, high reliability operation and use; •Adopt balanced XLR input and output interface and professional SPEAKON output interface; •The rear toggle switch is used to select stereo or bridged or mono operating modes; •The powerful power output of the machine allows the product to be used in more fields. 8Ω output power 2x300W 4Ω output power 2x500W
