问:我有一自制的放大器,采用了美国NS公司的LM3886功放块。我想配一对天朗水星M3音箱,不知能不能推得动?放音效果好不好? (太原 许中原) 答:用LM3886功放电路的额定输出功率为50W,但实际应用时因考虑电源波动和可靠性的问题,电源电压一般用得稍低一些,所以输出功率只能达到40W左右。如果听音室的面积不太大(如20平方米以下),推天朗的水星M3音箱是不会有什么问题的。天朗水星M3的灵敏度较高,达90dB,额定阻抗为8欧姆,故很容易推动。据一位音响爱好者实际制作
Q: I have a homemade amplifier, using the United States NS LM3886 amplifier block. I would like to match a pair of Celestial Mercury M3 speakers, I do not know can not move? Sound effect is good? (Taiyuan Xu Zhongyuan) A: LM3886 power amplifier circuit rated output power of 50W, but the actual application of power fluctuations due to consider And the reliability of the problem, the power supply voltage is generally used slightly lower, so the output power can only reach about 40W. If the listening room area is not too large (such as 20 square meters below), push the sky’s Mercury M3 speakers will not have any problems. Tencent Mercury M3 high sensitivity, up to 90dB, rated impedance of 8 ohms, it is easy to promote. According to an audio enthusiast actually produced
