DE Series Digital Power amplifier

DE Series Digital Power amplifier

DE series are the most cost-effective products in the switching power supply amplifier. The chassis is 1.5U height ,With its stable power output, Innocent and natural sound quality and complete power, it is widely used in small and medium-sized theaters, conference halls, hotel lobbies, bars, small and medium-sized mobile performance and karaoke and other occasions.


Product Advantages
1,1.5U height black SECC chassis, fashionable appearance , the weight of the whole machine is only 5 ~ 7kg(4x1200W is 12Kg), It’s convenient for transportation and saving installation space.
2,The front panel is configured with LED display screen, which can grasp the working temperature, volume attenuation and protection status and other information in real time.
3,The professional technology of temperature gain and power control guarantee the stability of long-term full load operation of the machine.
4,The filter capacitor are Hifi-grade special electrolytic capacitors with they can provide super-large current, low leakage, high temperature resistance, and long life, which comprehensively improves the overall performance of the power amplifier
5,There is a sensitivity switch in the back panel, so users can flexibly set different parameters to configure different speakers and occations.
6,The MOS tubes are international famous brand original products, so the output power is sufficient ,and the machine has the outstanding music performance that the sound quality is pure and natural, the HF&MF is transparent, the LF is full and elastic.
7,Blowing cooling system with temperature compensation technology. When the temperature in the chassis exceeds the normal range, the circuit automatically and intelligently detects and adjusts to keep the temperature in the chassis within the normal range, so as to ensure that the machine can work normally in any environment.
8,The internal structure is compact modular design which is independent operation of each channel with non-interference, that’s reliable performance device with green environmentally .
