The J.D.POLARDIO brand series amplifier design is mainly used for high-demand performances, theaters, multi-function halls, music bars, KTV private rooms, clubs, radio conferences and other occasions. The product has the high technology content, the stability is good, the operation is humanized, each product all considers the technology and the art synthesis performance! Polar engineers have adopted a more forward-looking digital design concept, with products with high-tech content and sound performance surpassing their competitors.
Product features:
J.D.POLARDIO polar all-digital integrated broadband amplifier, the world's first integrated all-digital circuit structure. Power utilization rate is more than 95%, small volume, light weight, small temperature rise, high damping coefficient, high and low tone adjustable, can be combined into nine tone styles. There is no extra connection line in the cabinet, and the stability is higher. The frequency response is wider than analog amplifier, which completely overturns your understanding of digital amplifier and leads the development direction of future digital power amplifier.
Applications: performance, entertainment clubs, conferences, multi-function hall and other sound amplification systems
