放大部分的核心为积累多年经验而开发研制的电子管全平衡放大电路，令你体会到电子管放大器特有
的优美音色。
采用双单声道全平衡放大电路高级设计，两声道完全独立；为了减小动态串音干扰，每声道各用一只电
源变压器，而且特制了变压器屏蔽盒消除电源噪声干扰。
使用ECC83(12AX7)和ECC82(12AU7)及5814(12AU7)音响专用电子管及配套镀金管座，音色表现甜美自
然，动态庞大。
高达30V不失真输出电压的电子管甲类输出缓冲器，轻易匹配众多后级功率放大器。
音量控制器为日本制造ALPS品牌大型四联高精度电位器，声道误差小，寿命长，而且确保音质和音色
表现优美。加入了遥控音量和音频信号输入选择系统，令使用者倍感方便。
机内大量使用音响专用高级元件，如使用德国WIMA品牌MKP音响专用薄膜无极电容，德国Mcap品牌
音响专用油浸金银箔及铝箔无极电容，高精度低噪声电阻，场效应晶体管伺服式高压精密稳压电源，令音质
和音色表现达到相当高的水准。
不平衡信号输入和输出端子均为镀金高级品，2个平衡信号输入及4个平衡信号输出端子均采用瑞士
NEUTRIK品牌产品,使音频信号得到更理想的传输。
本机具有光纤，同轴，USB数码输入端子。USB使用美国“XMOS”方案，解码芯片采用ES9038Q2M芯片。
电源输入插座采用日本FURUTECH(古河)品牌镀金产品，保险管采用进口发烧级产品。

CHARACTERISTICS CHARACTERISTICS
The core of the amplificationpart is a fully balanced tube amplifier circuit
developed for years of experience. Let you experience the better sound quality and
timbre charm of the tube balance preamplifier.
The advanced design of dual mono full-balanced amplifier circuit is adopted, and
the two channels are completely independent; in order to reduce the dynamic
crosstalk interference, each channel uses a power transformer to operate
independently, and a special transformer shield box is used to eliminate power noise
interference.
Using ECC83 (12AX7), ECC82 (12AU7) and 5814 (12AU7) audio-specific tubes and
matching gold-plated tube sockets, the sound performance is sweet and natural, and
the dynamics are huge.
The class-A tubeoutput buffer with up to 30V undistorted output voltage can easily
match many power amplifier.
The volume controller is a large-scale quadruple high-precision potentiometer
made in Japan ALPS, with small channel error, long life, and ensure beautiful sound
performance. The remote control volume and audio signal input selection system are
added to make users feel more convenient.
A large number of high-end audio components are used in the machine, such as
WIMA MKP audio specific film infinite capacitors, German Mcap brand oil-immersed
capacitors, high-precision low-noise resistors, field effect transistor servo-type
high-voltage precision regulated power supply, make the sound quality and timbre
performance reach a very high level.
The unbalanced signal input and output terminals are gold-plated high-grade
products, and the 2 balanced signal input and 4 balanced signal output terminals are
made of Swiss NEUTRIK brand products, so that the audio signal can be transmitted
more ideally.
This machine has optical , coaxial, USB digital input terminal. The USB uses the
American "XMOS" solution, and the decoding chip uses the ES9038Q2M.
The power input socket adopts Japanese FURUTECH Furutechgold-plated , and
the fuse adopts imported fever-grade products.

Function Description
NOTE:
1. The remote control should not be near overheated or humid places,and should not be exposed to direct
sunlight or strong light.
2. Do not subject the remote control to strong collisions or fall from a high place, otherwise it will damage
the remote control and make it impossible normal work.
3. Please use CR2032 button batteries; do not mix new and old button batteries or different types of button
batteries.
4. When the remote control is not used for a long time, please take out the battery and do not throw the
battery into the fire.
5. If the battery bursts, please clean and wipe the battery compartment dry, and then install a new battery.
6. Under normal use, replace the battery every 6 months.
GAIN
The user can choose the 0dB or -8dB gear according to the output level of the audio source;
when the output level of the audio source is too high, please select the -8dB gear (the GAIN light on
