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 K4-800 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. Attention! Normally rating power should be amp-power x 1,5times comparing power of tops speaker and amp-power x 2times for the subwoofer. To protect and extend your amplifier's working life, please don't use this amplifier under 2 ohms. K series amplifier are suit for Middle and High speaker, not good for Subwoofer.    Company Profile Our AdvantagesWhy choose us?1.Three years warranty.If there are quality problems, provide pictures or video, engineers judge the problem and provide after-sale support Products with CE ROHS certification.2.We are 10 years manufature about professional audio speaker and power amplifier.3.Our engineers have 10 years work experience, very professional.4.The product is light and suitable for performance and conferences.5.There is no minimum order quantity limit ,you can choose to order 1pc or 1000000pcs.No limit about quality.6.Products with CE ROHS certification.If you are interested in our products, please contact us/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
