DPA series adopt the latest technology; it is high performance professional amplifier, it can suitable for difference occasions with complete functions.

1、DPA series amplifier contains the mode DPA200, DPA450, DPA650.

2、Adopts the high-efficiency and large transformer, big capacity power supply

3、With the function of Low-cut and half-parameter equalizer. Special low-cut can cut off the harmful low frequency to loudspeakers, half-parameter equalizer can adjust mid-frequency

4、Equalizer can adjust frequency to high, mid and low.

5、Dynamic condensation function.

6、Mode selector switch for stereo, parallel and bridged-mono operation.

7、Reserve power is adequate, make sure never overload.

8、Balanced left/right volume channel design to minimize the crosstalk

9、Safe and convenient grounding system to make sure there is not any noise.

10、AC Voltage: 110-220V/±20% 50HZ。

11、Panel equipped with power supply indicator light, signal indicator light, protection indicator light and peak value indicator light.

12、Equipped with professional input/output, the input processed by balanced circuitry, connect line has no influence to the timbre

13、Standard tank, high quality panel and simple operation, 4Ohm high efficiency, long-term stability and excellent timbre make DPP amplifier the customer best choice.

14、Turn on delay protection, midpoint deviate protection, output shortcut protection, temperature protection, DUAL Variable Speed Fan Cooling.
