HONGDENG DM200是上海无线电二厂为开拓国产高级音响市场而开发的一款高质量后级功率放大器,以欧美极品级功率放大器的性能、音质、结构以至用料要求为设计的参考依据,采用了真正的双单声道(DUALMONAURAL)程式,两路放大器完全独立。该放大器的设计对供电系统非常重视,以两只600vA的高质量环型电源变压器分别为左右路供电,滤波电容总容量高达10万微法,输出级用
HONGDENG DM200 is a high-quality rear-stage power amplifier developed by Shanghai Radio II to exploit the domestic advanced audio market. It is based on the performance, sound quality, structure and material requirements of Europe and the United States for the most advanced power amplifier. Dual-channel (DUALMONAURAL) program, two-way amplifier completely independent. The amplifier design attaches great importance to the power supply system, with two 600vA high-quality ring power transformers were left and right supply, the total capacity of the filter capacitor up to 100,000 micro-law, the output stage with
