A500监听级Hi-Fi功率放大器
A500监听级Hi-Fi综合式功率放大器特点:
Reference A500 Integrated Amplifier Specifications
● 前后级独立供电(双变压器:前级150W、后级800W),高达80000UF大水塘(8只10000UF ELAN专用电容)
The separate power supply for pre-amp at 150W and amplifier at 800W by two power transformer, eight big 10000UF ELAN capacitor as filter purpose.
●后级采用场效应管(K1529、J200)电流推动,每声道六对山肯大功率管(2SA1295、2SC3264)并联功率输出
MOSFET of K1529 and J200 as current drive for the amplifier, six pairs of Sanken power transistor of 2SA1295 and 2SC3264 in parallel as big power output.
●可设置为全平衡单声道状态输出及前后级独立使用方式
Available to set full balance as single channel output, and the pre-amp and amplifier can be
used separately.
●动态偏流控制:输出小于20W时为甲类、大于20W时为甲乙类
Dynamic bias control: It will be Class-A amp when the power output is lower than 20W, and it will be Class A.B when the power output is higher than 20W.
●顶级专用散热器、独特前级全屏蔽结构、手感一流的主控旋钮
Hi-End heat sink in a custom-made, the special construction in full shield for pre-amp, and the main control knob have a good feel in operation.
