ATTENTION:
Normally rating power should be Amp-power x 1.5 times compared to the power of the top speaker and Amp-power x 2 times for the subwoofer. To protect and extend your amplifier's working life, please don't use this amplifier under 2 ohms. K series amplifiers are suited for Middle and High speaker, but not good for Subwoofer. |
| K4-1000 DSP Class D Amp Amplifier: K4-1000 1U 4-channel power amplifier, 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, adapt to the global scope, can carry higher power. |
| 1U Digital Amplifier K4-1000 DSP Feature: 1. Use a 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. The DSP module of K4 includes the basic functions of the processor, so you don't need to purchase an additional processor. 7. K4-1000 can be used for dual 8-inch line array. Not Recommend for Subwoofer! |
