三洋STK442-090定制先锋标PAC014厚膜功放模块80WX2@6欧 全新原装假一罚十。先锋公司找三洋定制的厚膜功放电路，凡是先锋公司的定制产品必定是经过精挑细选反复比较才确定的电路结构和声音特点。PAC014A等同于三洋STK442-090，推荐工作电压正负48V，输出功率80WX2@6欧，失真度THD0.2%。本系列产品声音细节、解析力、人声、低频力度均好于其他系列。模块拆解图上可以看到巨大的保护芯片，而且芯片关键部位均涂透明胶保护。只有后期的高端产品才会这样做，不可多得，买到就是赚到 三洋STK俗称三洋厚膜。经过调校的声音和高精度半导体工艺生产过程控制下，不是一般业余DIY玩家可以达到的水平。除了声场和解析力更好以外，低频力度强很多，完全是职业运动员和一般玩家的区别！这些厚膜电路是一直是专门给大品牌音响厂家的定制产品。早期许多著名的工厂用它们来制造功率放大器，如K + H，索尼SONY，松下PANSONIC、建伍KENWOOD ,杰伟士JVC、山水SANSUI、夏普SHARP、先锋PIONEER、爱华AIWA等差不多全部日本的音响厂家选用，而且沿用了超过二十年，整整影响了一代人，也是我们整整一代人年轻时候听到的带有强烈时代烙印的声音。每每听起都难以忘怀。三洋专门生产功放模块的公司后期被美国安森美公司（ON  semiconductor)收购，收购以后集成了三洋的传统工艺，再加上ON的独特设计，后期的产品更加出彩，至今仍被美国的大公司采用，如 BOSE，如欧洲的真力Genelec!          PAC014A厚膜实际听感很耐听，声音细节、解析力、人声、低频力度均好于其他系列。   基本参数：   供电电压：交流双25V-38V   输出功率：50W+50W  8Ω   110W+110W 4Ω 实测持续最大输出功率   频       响：20Hz-50kHz   输入灵敏度：700mV   输入阻抗：50K   放大倍数：32倍   失       真：0.2%   尺       寸：155 x...
