D20KQ 4 Channel Class D Digital DSP Amplifier 16000W for Subwoofer

Overview:

D20KQ 4 channel class d amplifier is the innovative technology achievement of Sanway Audio. It integrated with reliable power supply, compact class-d design circuit and high efficiency and unique cooling system.

 

The D20KQ consists of 4in&4out digital processing with 20 factory preset configurations enable user can modify and store the presets conveniently.

The built- in DSP including a crossover, parametric EQ filters, limiting and alignment delay, it eliminates the need for outboard loudspeaker processors.

 

The D20KQ combines four channels of extremely powerful amplification with networking, 4in&4out digital processing, amplifiers, power supply and connected mains supply resulting in unique operational benefits.

 

Features:

1.4x2100W at 8 ohms, 4x4000W at 4 ohms.

2. innovated  high-efficiency  cooling system with special design for fast cooling

3. DSP function: Mute, Polarity, Gain, EQ, Xover, Limiter. 

4. Ethernet function (Wi-Fi):to control many D20KQ amplifiers with one computer 

5. Super power; compact circuit inside, high efficiency and lightweight
