性能特点 前面板功能
A30电子管功放最大特点是取消了传统胆机的输出变压器，使用了功率半导体晶体管来取代输出变压器，
好处是消除了传统输出变压器所带来的各种附加失真;如频率失真、相位失真、瞬态失真、方波失真等，从而令
A30的频响范围可达10Hz-60KHz±1dB，输出功率可达200W×2(8Ω)，远远超越了传统KT88(6550)胆机的输出功
率(100W以内)，对驱动低效率的书架式音箱轻松自如、对高效率的大型落地式音箱也轻易驱动。
由8支大功率晶体管组成功率输出级，也可切换为4支大功率晶体管输出级来进行阻尼系数调整,以方便搭
配各种不同灵敏度音箱的要求。还加上可切换偏甲类或甲乙类偏置开关以方便调整音色。
前置放大部分采用ECC83电子管初级放大，6N11电子管作第二级电压放大，KT88(6550)大功率电子管作
甲类输出驱动电路，令本机具有传统胆机优美的音色表现。
电子管交连电容器为德国Mcap品牌铝箔油浸系列高级音响专用电容器。晶体管功放电源所用的滤波电容
为日本ELNA品牌FOR AUDIO系列10000uf/80v规格, 无论音色和音场都有上佳表现; 对整机的音质和音色提高
起重要作用。
电子管与场效应管混合型精密高压稳压电源，电压稳定性极高。交流纹波系数低，音色表现更有“胆味”。
采用日本ALPS大型遥控式音量电位器,具有噪声低，无音染，两声道间误差小的特点。
附加有等响度开关功能,可在小音量时提升高低音表现。
可与手机、手提电脑、平板电脑等设备进行蓝牙(5.0)数码音频连接。也可与iPod、iPhone、iPad、CD、DVD、电
视高清机项盒进行数码或模拟音频连接。附有光纤、同轴、USB数码信号输入接口，并具用24Bit/192K数模转换
精度,支持DSD512格式。还设有一组模拟信号平衡输入端子。
功率输出采用大型镀金接线柱可方便与众多音箱线良好连接。
铝合金多功能红外线高级遥控器,令操作手感更佳更时尚。 3音频输入选择旋钮

CHARACTERISTICS CHARACTERISTICS
A30(Integrated Tube Stereo Amplifier) is the biggest feature is to cancel the output
transformer of the traditional machine, the use of power semiconductor transistor to
replace the output transformer, the benefit is to eliminate the traditional output
transformer brought by various additional distortion; Such as frequency distortion, phase
distortion, transient distortion, square wave distortion, etc., so that the frequency
response range of A30 can reach 10Hz-60KHz±1dB, the output power can reach
200W+200W(8Ω), far beyond the traditional KT88(6550) tube amplifier output power (within
100W). To drive the Bookshelf speaker of low efficiency easily and freely, to the large floor
speaker of high efficiency also drive easily.
The power output stage is composed of 8 high-power transistors, which can also be
switched to 4 high-power transistor output stages to adjust the damping coefficient, so as
to facilitate the matching of different sensitivity speakers. It also adds the switch of partial
class A or class AB offset switch to facilitate the adjustment of timbre.
The pre-amplifier part adopts ECC83 electron tube for primary amplification, 6N11
electron tube for the second stage voltage amplification, KT88(6550) high-power electron
tube for the class A output driver circuit, so that the machine has the traditional tube power
amplifier elegant timbre performance.
The electronic tube interconnecting capacitor is a special capacitor for advanced audio
of German Mcap brand aluminum foil oil immersion series. The filter capacitor used in
the transistor power amplifier power supply is Japanese ELNA brand FOR AUDIO series
10000uf/80v specification, no matter theTimbre and sound field have a good performance;
It plays an important role in improving the sound quality and timbre of the whole
machine.
It adopts a hybrid precision high-voltage stabilized power supply. The voltage stability
is extremely high, while the AC ripple coefficient is extremely low. The tone performance
is more "electronic tube flavor".
Japanese ALPS large remote control volume potentiometer is used, which has the
characteristics of low noise, no sound dyeing and small error between two channels.
Equipped with an loud function, which can improve the performance of high and low
voice when the volume is small.
Bluetooth (5.0) digital audio connection with mobile phones, laptops, tablets and other
devices. It can also be connected with iPod, iPhone, iPad, CD, DVD, HD TV set-top box for
digital or analog audio connection. With optical fiber, coaxial, USB digital signal input
interface, and with 24Bit/192K digital-to-analog conversion accuracy, support DSD512
format. There is also a set of XLR input terminal for analog signals.
The power output terminal adopts large gold-plated terminal, which can be easily
connected with any speaker wire.
Aluminum alloy multi-function infrared a remote control, make the operation feel
better and more fashionable.

BLUETOOTH RECEIVER
Used for digital devices and "Bluetooth" transceiver interconnect signals.
Operation example:
1.After the power of the audio combination is turned on, the Bluetooth
enters the waiting state for pairing.
2.Enter the phone settings, turn on the phone’s Bluetooth function, scan
to find the device; the phone will find the word "ShengYa", operate the
phone to connect with it (you don’t need to enter a password to connect).
3.After connecting, turn on the mobile music player, press the play button,
and the sound will be broadcast on the speaker on the audio combiner.
Notice:
1.If the Bluetooth of the mobile phone has not been turned off, and the
Bluetooth of the speaker is in a state of pairing, when the speaker
combination is turned off, the next time it is turned on, the Bluetooth will
enter the reconnecting state; after 10 seconds, it will enter the waiting for
pairing state.
2.After the Bluetooth of the audio combination device and the mobile
phone is out of the receiving distance or disconnected, if it returns to the
normal distance within 60 seconds, the Bluetooth can automatically
connect back to the connection, otherwise the Bluetooth of the audio
combination enters the waiting state for pairing.
3.After the speaker combination is connected with Bluetooth, it is
necessary to turn off the Bluetooth function of the current phone before
connecting with the Bluetooth of another mobile phone, and then operate
the Bluetooth search of another mobile phone to connect.
4.The speaker combination Bluetooth can be connected with bluetooth
products of digital products such as laptops, mobile phones, IPDA and
other digital products.
