LM-512CA 前级放大器

产品特点:

●采用四只优质镍片/坡膜合金宽频响高音质EI输入输出变压器作输入输出音频信号耦合

●使用专门为本机设计的EI型双电源变压器(左右声道独立)

●使用6KZ8作电压放大输出级用6922作推动管、美国RCA整流胆22DE4作高压整流

●左右声道完全独立设计,力求两声道音色一致

●不惜成本采用Multicap音频电容,美国IRC电阻,飞利浦BC轴向电容,松下继电器,

镀金CMC电木管座,优质RCA端子、平衡插座

●红外功能遥控器可作音频输入选择、音量大小和静音遥控操作

●成功地将直观别具一格的音量刻度盘设计融入古拙大气的设计理念

●开机静音延时功能(约30秒)

●选用日本ALPS高档马达电位器

●方便安装的拔插式真空管防护罩

Product features:

●With four high quality nickel sheet/POE film alloy high quality wide rang EI as input and

output of audio signal input/output transformer coupling

●Using specially designed for the native EI type double power supply transformer

 (independent) around a track

●Use 6KZ8 as voltage amplifier output stage in 6922 as drive pipe, the RCA 22DE4 as

high voltage rectifier rectifier bravery

●Left and right channels completely independent design, and strive to two channel tone

●At the cost of using Multicap audio capacitor, the IRC resistance, axial capacitor, philips

BC panasonic relay, gold-plated CMC electric woodwind, high-quality RCA terminal,

balance the socket

●Function of infrared remote control can make audio input selection, volume and mute

remote control operation

●Successfully to the intuitive having a unique style into the volume dial design like that

design idea of the atmosphere

●Boot mute delay function (about 30 seconds)

●Selects the Japan ALPS high-grade motor potentiometer

●Convenient installation drawing plug-in valve cap
