DK3000 is high-ended professional digital power amplifier. excellent working with subwoofer - Deep sound for subwoofer, powerful, high power, very stable / very reliable.

DK3000 Legendary productivity：

1. Save space and weight: only one rack space (1U) and 12 kg

2. Green audio power: most power consumption is converted to audio output power, up to 92%

3. Standby sleep mode, ultra-low idle power consumption

The DK300 is very powerful, with a total output power of 12700W and only one rack installation space, making it one of the most powerful and technologically advanced power amplifier products on the market.

The efficiency is over 92%, low calorific value means stable and reliable performance, more durable.

Extremely wide power supply adaptability, built-in power regulator of 20000W, can adapt to the worst power supply environment, completely solve the problem of voltage instability in remote areas.

Select all kinds of top components carefully, each power amplifier components more than 4000, a large number of imported raw materials, such as the United States Fairchild, Ansenmei, Germany Infineon, Japan TDK, stmicroelectronics, the selection of HIFI level chip, timbre reached an unprecedented height of digital power amplifier.

The protection circuit of each sound channel is independent, even if a certain sound channel cannot work, it will not affect other sound channels, providing higher security for each performance.

Each power amplifier has passed more than 100 comprehensive tests of AP audio instrument, ensuring that each power amplifier achieves the optimal parameters and performance and

maintains a high degree of product consistency.

The DK3000 is the perfect choice for a place that requires relatively high continuous power and high requirements. The emphasis on timbre and high efficiency, while achieving good stability, portability and adaptability, make the DK3000 a perfect choice.

DK series amplifiers are the first choice of first-class system designers, sound engineers, and system technicians to provide the most reliable and highest level of power and dynamic margin in the smallest size possible.

POWER UNIT

1. Advanced switching mode power supply technology worldwide enables high performance and compact size. 

2. Power factor correction technology, the realization of very low power consumption and very wide power operating range, power factor up to 0.99, the power range of 90V- 270V.

3. Low surge limits reduce the ac surge current and eliminate the need to purchase expensive power sequesters.

4. Full bridge switching power supply topology, strong current conversion ability, more stable, more reliable.

5. Soft power start, boot anti surge ability, to achieve the real meaning of safe boot.

6. Power short circuit protection

7. EMC electromagnetic compatibility

8. Double thermal protection of power supply, overload intelligent modulation power, so that the power supply is always in the safest state

 Audio amplifier unit

1. Fixed frequency switch mode output level, to achieve high quality of sound accuracy, strong bass, clear and fine treble, music detail performance Incisively and vividly. 

2. Three groups of closed-loop gain loop control. 

3. Each channel circuit is independent of each other

4. The core module goes through three anti-corrosion treatment, anti-corrosion, anti-moisture and anti-dust. 

5. HI-FI chip produces unique sound quality

Comprehensive protection design

1. AC protection: when the AC power supply voltage exceeds the operating range, turn off the power supply

2. Clipper limiter: prevents severely clipped waveforms from reaching the speaker while still maintaining full peak power output.

3. DC protection: prevents infrasound signal from reaching the speaker at the output end

4. Overhigh frequency protection: prevents strong, non music, inaudible high frequency signals from reaching the speaker

5. Short circuit protection: automatic protection reset function, prevent short circuit or other stress failure of power amplifier

6. Long term amplitude: prevents stable long term RMS (non-audio) signals from reaching the speaker, reducing the maximum output

7. Thermal protection: the maximum normal operating temperature of output level and power supply is 75℃

Temperature controlled continuous variable speed fan, front to back tunnel cooling system

Temperature warning: when the temperature reaches 70℃, the LCD screen will give warning, the yellow temperature lamp will be on, the output power will be compressed according to the temperature variable, until the overheating warning is removed, so that the power amplifier will not appear after the overheating protection without sound phenomenon

8. Switch machine mute: prevent the power amplifier switch machine produce impact sound.

9. Overload protection: prevent overload damage of components

10. Signal line hot plug protection: prevents the power amplifier from damaging the power amplifier due to the excessive surge generated by the hot plug input Canon wire when the power amplifier is on.
