评述: | 上海出中道PA-5II后级 每边8欧150W
上海出自用中道PA-5II后级 每边8欧150W,价格4800,或可交换带DTS、每边功率8欧100W 以上的AV功放。电源已换成日本古河插座,可玩线。内部结构与美国精神后级相似(同美国 精神工程师设计),有两只大滤波发烧电容每只47000薇法,一个大的全封闭环形变压器, 内部设计很高贵。中道本是美国工厂,后被日本收购。新机前后级要25000多。电话 1391616785 后级指标: continus average power output(new ihf):150W*2(an 8ohms,both channels driven,20- 20000 Hz,0.05%THD) dynamic pewer per channel:225 W(8 ohms) dynamic head room (new ihf):1.7db(8 ohms) power bandwidth (half rated power,0.05% thd):5Hz-50Hz damping factor (new ihf)20hz/1khz/20khz:Greater than 60/60/60 input sensitivty/impedance (new ihf):1.6V/50 k ohms(1 W output) frequency response (1w,new ihf):20-20000 Hz +0, -0.2db; 7-150000Hz +0, -3db signal-to-noise ratio(input shorted power,ihf A-WTD):better than 120 db RESIDUAL NOISE LEVEL (ihf a-wtd):less than 30毫伏 total harmonic distortion(rated power,20-20000hz):Better than 0.05% stereo separation(lnput shorted)100hz/1khz/10khz:100/90/70 db output complement:12 transistors per channel output current capability:18 A continuous, 70 A peak (per channel) power supply:470 VA toroidal transformer,94000 mf toter capacitance power source:120,220,240 or 110/120/220/240 V AC; 50/60Hz(According to country of sale) power consumption:650 W max dimensions*:435(W)*157(H)*421(D) mm approximate weight:21.5kg;47lbs;6oz. |
