J. D.POLARDIO is committed to producing high-quality professional products. After years of research and development and rigorous testing in numerous locations
Through testing and experimentation, we have launched a brand new JD series dual-purpose amplifier with fixed resistance/voltage. It has outstanding performance and can effortlessly drive full range and low-frequency speakers. It has two tone selection switches, comprehensive protection facilities such as voltage limit, short circuit, overcurrent, overheating, DC output, etc. It also has a parallel bridge selection switch, two sensitivity adjustments, a more beautiful front panel, and a filter screen added to minimize the adverse effects caused by dust. Carefully tested electronic components combined with advanced and reasonable circuit design make the sound quality more perfect; The front-end amplifier is powered by a wide voltage regulator circuit and is independently separated from the back-end amplifier, which increases the dynamic clarity of the sound; This series of products has the characteristics of low noise and small on/off impact.
The DP series is a high-performance high-power amplifier designed specifically for systems with extremely high sound requirements. Inheriting the style of J.D.POLARDIO, the DP series amplifiers perform even better, with a strong and powerful low frequency, magnetic texture in the mid frequency, clear and natural high frequency, and unparalleled resolution. They are essential equipment for performance venues with high requirements for power and sound quality.
