Company Advantages1. Gisen 1u digital power amplifier is manufactured with high-quality materials. The materials have to be tested under professional machines for their mechanical properties, such as hardness, brittleness, tensile strength, and so forth. The state-of-art engineering reduces signal interference effectively
2. Chemical-free and certified to the highest standards available today, this product allows users to sleep and to breathe naturally. The product can be applied to such scenarios as KTV, club, and conference
3. The product is corrosion resistance in extreme conditions. Its parts have been electroplated with a layer of metal membrane to resist the chemical influence. The built-in loudspeaker protection circuit protects high volume bursts of audio
4. The product has great surface quality. The destruction of the surface will be not easily susceptible to wear such as cracks, notches, holes or even broken off. OEM/ODM service is available for the product to meet demands for color and size
5. The product has become renowned for its energy efficiency. The ammonia-based refrigeration system can achieve great cooling effect while using less power. Each channel has independent limiter and compressor, ensuring no interference caused by other channels
