For MF/HF speakers, K4-1400 power amplifier should be 1.5 times than your speaker rated power.
K4-1400 is not recommended for working at 2ohms. Also not recommended for subwoofer.
1U Digital Class D Power Amplifier K4-1400 Feature:
1. Use the Class D 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 lightweight and very small space occupation rate.
5. It is widely used in large and medium-sized bars, banquet halls, and outdoor performances.
6. Create SUPER sound quality, good for dual 8-12 inch line array or pa speaker.
6. The bridge-mode operation for Touring Applications
Small size, lightweight, 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, adapts to the global scope, can carry higher power.
