K4-1400 Digital Power Amplifier
K4-1400 1U 4-channel power amplifier, small size, light weight, easy to install. The circuit uses a Class D power amplifier module, a reliable and efficient R-SMPS stabilized power supply system, which has extremely high efficiency and controllability, and also has extremely high power density, which can adjust the current waveform according to the AC voltage waveform. Wide voltage operation, adapt to the global scope, can carry higher power.

Digital Amplifier K4-1400 Feature:
1. Use ClassD power amplifier module. Unique peak clipping limiter and ripple reduction. 
2. The perfect protection system effectively reduces the losses caused by improper use. 
3. The perfect circuit design makes the bass strong and powerful, and the mid and high frequencies are transparent and clear.
4. 1U design, its light weight and very small space occupation rate.
5. It is widely used in large and medium-sized bars, banquet halls, and outdoor performances.
