Guangzhou Gisen Audio Equipment Factory stands out among other 4 channel dsp amplifier manufacturers in the industry. Gisen Audio's top 10 power amplifiers series are created based on unremitting efforts. Gisen Audio 4 channel dsp amplifier is manufactured from materials that are sourced from reliable suppliers. Its surface is well processed by a layer of paint to resist rust. The buildup of heat and moisture can contribute to “tossing and turning” as the body seeks to alleviate the issue. And this product can solve this problem. Its compact design is ideal for mounting in low clearance location.
