Description

FEATURES :

preamp and power amp is a sub-structure, reasonable layout, lower noise.
Before the class is “SRPP” circuit, and increase the cathode output device, wide frequency response, low output impedance.
After amplification for low-level resistance of the power transistor (845), and A single-ended amplifier, the sound quality is good.
After the circuit level to promote the “SRPP” circuit, and for the dual parallel, wide frequency response, pushing strong.
Japan imported the audio output transformer using dedicated oriented silicon steel Z11 (0.35mm thick) and oxygen-free high strength enameled wire and special winding process multi-group production, so that the machine wide frequency response, to ensure that the machine high, medium and low frequency sounds good , transparent and powerful.
This machine adopts foreign name Factory sound dedicated enthusiast and non-polarized electrolytic (MKP) Need for high-quality imported French Suren gold blocking capacitors and manufacturing, the main audio channel dedicated to use imported from Japan (ALPS) volume motor potentiometer, with quiet background music, low noise, no sound pollution and durable.
High-voltage power supply for the automatic delay control, can effectively extend the tube life, and with remote control function.

特征 ：

前置放大器和功率放大器是一个子结构，布局合理，噪声较低。
之前的类是“ SRPP”电路，并增加了阴极输出装置，频率响应宽，输出阻抗低。
在放大功率晶体管（845）和单端放大器的低电平电阻后，音质良好。
后级电路提升为“ SRPP”电路，并为双并联，频响宽，推力强。
日本进口的音频输出变压器采用专用取向硅钢Z11（0.35mm厚）和无氧高强度漆包线及特殊绕组工艺进行多组生产，使机器的频响范围大，确保了机器的高，中低频听起来不错，通透而有力。
本机采用国外名厂发烧专用发烧友和非极化电解（MKP）优质进口法国苏仁金阻隔电容器并制造，主要音频声道专用于日本进口（ALPS）体积电机电位器，具有静音背景音乐，噪音低，无声音污染，经久耐用。
用于高压电源的自动延迟控制，可以有效地延长灯管寿命，并具有遥控功能。
