If installed in the rack case, you need to leave enough gap in the power amplifier all-around, to ensure that air circulation without difficulty to facilitate the machine cooling. Using this amplifier near the heat source for long time will affect its performance, please donot use it near heat source. Please leave the amplifier away from the tuner and TV as far as possible in installation, because too close installation will cause noise and TV images instabllity.OPERATION WARNINGSPlease check if the supply voltage is same with the rear amplifier marked, because the damage caused by the supply voltage error is not covered under warranty. So make sure that the supply voltage is same with the rear amplifier marked when using the amplifier. Please turn off the power before you connect the input and output cables to the amplfier.More delicate modelBased on pulse width modulation technology (PWM) which has been 30 years in the field of power converters, adopting full digital circuitry pulse width modulation to provide high reliability, this amplifier features small size, low weight, easy installation, transport and storage.Higher efficiencyOne of the most significant features is that the efficiency of this amplifier is almost independent from the output level. Conventional amplifiers achieve their best efficiency only at full rated power output.Compared to a conventional amplifier, this amplifier offers very high efficiency and delivers more power to the loudspeakers with much reduced heat dissipation. And the higher efficiency reduces dimension, weight and power consumption to a large extent. Moreover, the power conversion efficiency of this amplifier is more than 80%.More accurate soundCrystal-clear high frequency, compact powerful excellect low frequency, the most accurate reproduction of an audio signal, professional design ensures high performance parameters such as distortion, frequency response, conversion rate, power bandwidth and damping rate. The PWM converter works like high-frequency signal sampler, converting variable amplitude (sound) signal into equivalent pulse sound signal output, the amplifier uses a higher frequency conversion to obtain high-resolution audio source.Better protection functionWhen the amplifier works, it will prevent / correct every possible error, you can feel free to use in various conditions. It provides your audio system maximum power and the most secure guarantee and increase the long-term reliability.1. Intelligent temperature control fan:Intelligent temperature control amplifier circuit can detect the actual temperature, constantly adjust the fan speed to make the parts inside of the machine to keep a good working environment according to the need. It is to achieve the effect of low-noise, low rotation and long-term reliability, at the same time it meets the cooling needs of amplifier as well.2. Temperature Protection:If the temperature of the amplifier is too high or the cooling condition for amplifier around is bad, amplifier protection circuit monitors the MOS-FET temperature: When the the temperature is too high, it will reduce the amplifier output power, the THERMAL light twilight in the front panel;if the temperature exceeds the power amplifier’s affordable temperature, the amplifier will start over-temperature protection and cut off the output of the amplifier. Now the THERMAL light in the front panel will light up. The amplifier automatically return to work when the temperature falls.3. Short circuit, Over current protectionWhen the amplifier is in lower load than rated impedance or short circuit, when the output current exceeds the maximum limit current, the protection circuit will start. It cuts off the output of the amplifier and step into the protection status. If the short circuit fault removes, the amplifier will automatically return to normal operation Status in 3-5 seconds. The FAULT light will light up in the front panel when the Short-circuit protection works.4. DC-fault protectionIf the internal components of the amplifier are abnormal and the amplifier output appears DC signal,loudspeakers.5. Over-voltage protectionWhen the input voltage exceeds the allowable range, amplifier will go into protection state until the supply voltage returns to the normal.FRONT PANEL1. Power Switch:Control the on and off of the amplifier, "∣"is power on , "○" is power off.. 2. Gain:Two input control knob in the front panel can adjust the Gain of the amplifier A,B channel.

天龙功放设置大全

天龙功放设置大全

天龙功放设置大全随着近年来高清,HTPC和次世代音频的流行,很多新烧友第一次购入了功放。

而很多资深的发烧友也借着这波次世代的浪潮升级了自己的功放.在几个功放厂商中,天龙以其合适的价格,强劲的功能和火爆的影院效果吸引了很多烧友. 然而天龙的说明书读起来相对晦涩,而设置菜单不但往往为英文,而且做得也不够人性化,以致于很多烧友在新机器到家以后摸索半天,也往往还不能发出美妙的声音。

甚至有些烧友在未能找到最佳设置之前就提前放弃,这样器材就不能发挥所有的潜力,殊为可惜。

本文将从天龙功放简单的连接及设置说起,然后再对某些设置进行详细解释,希望能起到攻略的作用,让各位接触天龙功放不久的烧友们都能合理的设置自己的功放,使其表现能对得起花下去的银子.本文所涉及的设置适用于大多数的天龙功放,然而不同型号之间总有细微不同,如果您发现文中所述与您的功放不一致,只能请您自行钻研说明书了.一、连接新机到家后,不要马上插上电源,先看看机器的背面,是不是类似于下图,只是插口少了一些?什么?您的功放后背和图里的一模一样?先让俺拜一下买得起天龙的旗舰型号的米人!连线时您可能会注意到功放上有很多"DVD”,"HDP”,"AVR"等字样。

这些其实不用理会,在以后是可以在设置里随时更改的.唯一要注意的就是模拟信号不要插错了,比如色差的Y,Cb,Cb等.对于一般的应用,这一步应该是比较简单的。

二、音箱参数设置确定音箱等都连接好了,并且极性无误以后,就可以插上电源线并开机了。

记得把电视机也打开,在进行设置时,看电视机上的OSD 比看功放上的小屏幕要舒服多了。

这一步可以通过两种方式来做,一是自动设置(Auto Setup),二是手动设置(Manual Setup)。

某些初次使用功放的玩家可能不会信任自动设置功能,事实上这是一个相当强大的功能.天龙功放使用的自动设置功能来自于第三方的Audyssey公司.使用方法为将机器带的麦克风置于听音位置,机器发出测试音,然后对麦克风收到的声音进行分析计算后得出适合各声道音箱的设置.对于大多数没有声压计的烧友,笔者都建议至少跑一遍Auto Setup然后手动进行微调。

功放机按键说明书

功放机按键说明书篇一:音响操作说明音响操作说明针对于本系统,具体操作如下: 1. 话筒及音乐输入连接:调音台可以接入有线话筒、无线话筒、DVD、电脑音频等;有可种可以接入的插口,方便进行连接(如下图所示)。

第1路到第8路一般接入话筒,第13到16路为DVD等音乐信号输入;第9路到第12路比较特殊,即可以接入话筒,也可以接入DVD等音乐信号(已经标明L、R声道),只是接口不一样而已。

注:1、如果上面的卡侬口已经接入设备,就不要再用下面的单插插口,也就是说,这一路里面只可以接入一路音源;下面的INSERT插口,本系统用不到。

2、如果要接入普通的会议话筒,可能需要48V供电,那么本调音台具备此功能,只需要把调音台的48V供电开关打开即可,如下图所示;2. 开启系统:先打开第一台电源时序器,电源时序器会依次给所接设备供电;等第一台电源时序器的8路电源依次打开完毕,再打开第二台电源时序器,同样,等8路电源全部打开方可进行其他操作。

注:专业音响设备具有开关顺序,开启时顺序为:音源设备(如DVD、话筒接收机等)、周边设备(如调音台、均衡器、效果器等)、功放。

否则的话,可能会产生“嘭”的声响,以至于损坏设备。

3. 播放音频、视频:首先把调音台右下角总音量的推子调整到合适的位置(如图一所示),高度最好不要超过0刻度;然后打开DVD 机,把光盘放入,让DVD处于读碟播放状态;找到调音台对应DVD接入的那一路,把方块透明的开关按钮按下,使其处于点亮状态,再按下下方的红色ST按钮;然后轻轻从下方往上推长方形的音量推子,直到音量足够为止(如图二所示)。

高中低音调整:正常情况下,无需调整音乐音频,因为DVD或电脑放出来的都是原始音频,如果想调整音乐的高中低音,可以通过调音台自带的简单均衡器进行调整(如图三所示),上面的为高音旋钮,中间的为中高频旋钮,下面的为低音旋钮。

音视频矩阵切换:如把第1路音频、视频切换到第2路输出,那么操作方法是:按AV键然后从右侧上边的一排(输入键)按下1键,然后再从下面一排(输出键)按下2键,最后再按下ENTER 键即可。

ELECTRONIC MUSIC AMPLIFICATION SYSTEMOperating Instruction ManualModel KD-1Toa Electric Co., Ltd.KOBE, JAPANPrecautions (1)General Description (2)Features (2)Front Panel: Names of components & their usage (3)Rear Panel: Names of components & their usage (4)Block and Level Diagrams (5)Specifications ........................................................................... 5~6 Appearance . (6)1. Power SupplyThe KD-1 is designed to operate on local AC (50/60Hz) Mains, ±10%.2. XLR Type Audio ConnectorThe connectors are wired as follows.The pin 1 is ground (shield), the pin 2 cold (low, minus), the pin 3 hot (high, plus).3. Phantom Power SupplyThe phantom power switch on channel 1 input permits the user to supply 48V DC through the input connector to a condenser microphone. If phantom power is not required, the switch must be in the "off" position.4. Description of components and functions of the KD-1Various descriptions are applied, depending on each manufacturer. In our Operating and Instruction Manual explanation of components and functions is made according to Toa's usage for them.The TOA KD-1 is a complete electronic music amplification system in a single portable package, consisting of a mixer, spring reverberation unit, power amplifier, and full range speaker system.The mixer section provides four input channels, and an effects patching loop with crossfade and level controls. Each input features 2-band active EQ, and level control. Input channels 1 and 2 feature Effects on/off switches, while channels 3 and 4 feature input sensitivity switches. Channel 1 also features an electronically balanced XLR mic input connector with switchable 48 volt phantom power, for use with condenser-type microphones.The 50 watt RMS internal power amplifier features Auto Comp compression circuitry, with an LED indicator, to ensure distortion-free performance and protection for the internal 12-inch heavy duty speaker system.The KD-1 is covered in a durable and attractive high tech gray vinyl fabric.System FeaturesFour input channels50 watts power amplifier outputAuto Comp compression circuitry w/indicatorPower amplifier protection circuitry w/indicatorBuilt-in heavy-duty 12"(30cm) two-way loudspeakerBuilt-in spring reverberation unitEffects patching loop, returnable to system mixing buss with crossfade and level controlsEach Input ChannelTwo band EQInput channel 1 has electronically balanced XLR mic input connector with switchable 48 volt phantom powerInput channel 1 and 2 has Effects ON/OFF switchesInput channel 3 and 4 has Input Level Selector switchesLow Equalizer Control [LOW] The low EQ control alters the low frequency response of the input channel, providing ±15dB at 20Hz of continuously variable ac-tive shelving equalization. The "0" detented position provides flat audio response.High Equalizer Control [HIGH] The high EQ control alters the high frequency response of the input channel, providing ±15dB at 20kHz of continuously variable active shelving equalization. The "0" detented position provides flat audio response.Input Channel Level [LEVEL]The level control provides con-tinuously variable adjustment of the channel output to the mixing busses, thus determining the level of the channel in the main sound system mix. The nominal level of the input level control is at the "0" dB position.System Level Control [SYSTEMLEVEL]This control determines the over-all volume level of the KD-1 sys-tem.Headphone Jack [PHONES]The headphone jack will acceptany stereo headphone with 8ohms impedance, or higher. Thisjack provides the same signal asthe speaker output. When a plugis inserted into the jack, thespeaker output is automaticallyswitched off.Power Amp CompressionIndicator [COMP]The Comp LED lights when theinternal compressor is activated.The compressor is provided toprotect the speaker system bycompressing the input signallevel of the power amplifier whenclipping occurs in the outputstage. Frequent flashing of theLED is not reason for alarm.However, a constant or steadylight indicates that the KD-1 isbeing overdriven and that theinternal power amplifier is poss-ibly "under powered" for thatapplication. The output level ofthe KD-1 should be decreaseduntil the LED only flashes inter-mittently.Power/Protect L ED I ndicator[POWER/PROTECT]The LED indicator lights greenwhen the power switch is "on".The LED turns red when thethermal protection circuit is acti-vated, or the internal fuse (foroverload protection) is opened.Reverb/Effect Level Control[REV/EFF LEVEL]This control governs the amountof reverb signal through the rever-beration unit (built in), and effectsignal returned through the effectreturn jack (EFF RET) to the sys-tem mixing buss. The singal ofReverb signal and EFF RET iscontrolled simultaneously.Cross-fade Control for Reverband Effect [REV/EFF X-FD]When this control is in the centerposition, the Reverb signal (thusthe internal reverberation unit)and EFF RET signals are equallyassigned to the System mixingbuss. Rotating the controlcounter-clockwise decreases theEFF RET signal level, keeping theoriginal level of the Reverb Sig-nal. Rotating the control clock-wise decreases the Reverb signallevel, keeping the original level ofthe EFF RET signal.Effect Return Jack [EFF RET] This 1/4" phone jack is used in conjunction with the Effect Send jack to connect an outboard effects device (i.e, delay or re-verb) to the KD-1. The Effect Return jack should be connected to the output of the effect. Nomin-al input level is -20dB with an impedance of 10k ohms.Aux Input Jack[AUX IN]The unbalanced 1/4" phone jack have a nominal input level of -20dB and an impedance of 10k ohms.Effect Send Jack [EFF SEND]This 1/4" phonejack is used inconjunction with the Effect Re-turn jack to connect an outboardeffects device (i.e, delay or re-verb) to the KD-1. The Effect Sendjack should be connected to theinput of the Effect. Nominal out-put level is -l0dB with an impe-dance of 1k ohms.1/4" Phone Channel Input[INPUT]This jack is a standard, unba-lanced 1/4" phone jack, with anominal level of -30dB and animpedance of 100k ohms. When aplug is inserted into the 1/4" inputjack, the corresponding RCA pinjack is automatically switchedout of the input circuitry.RCA Channel Input[INPUT]The RCA pin input jack is unba-lanced, with a nominal level of— 30dB and an impedance of 100kohms.Phantom Power On/Off switch[PHANTOM]This switch alternately turns"on" and "off the phantom pow-er (48V DC) for the XLR connectorassigned to Channel 1. Theswitch should remain in the offposition when a condenser typemic is not in use.Power Switch [POWER]The power switch is a three-position type with the middle position being the "off' position. The KD-1 should be operated in the switch position which pro-duces the lowest amount of sys-tem hum.AC Power CordThe power cord is of the three-wire type with proper grounding facilities built-in. (6ft.)Caution — The ground pin should not be removed under any circumstances. If the KD-1 must be used without proper ground-ing facilities, a suitable grounding adapter should be utilized. Op-eration of the KD-1 with proper grounding techniques will result in less system noise and greatly reduced shock hazard.AC FuseWarning: To avoid possible equipment damage and/or per-sonnel injury, the fuse should always be replaced with same type and rating. Using improper fuses will also void the warranty. The KD-1 should always be dis-connected from AC outlet prior to changing fuses. If fuse repeatedly fails, the unit should be referred to qualified service personnel for repair.Recording Outout Jacks[RECOUT]The unbalanced RCA pin jackshave a nominal output level of-10dB and an impedance of 1kohms. The Recording Outputs arepre-fader signals for connectionto tape recorders. Any change inthe level of the System Levelcontrol will not alter the level ofthe recording outputs.Speaker Jack [EXT. SP]The external speaker output is astandard 1/4" phone jack. Speakercables (recommend at least #18gauge wire) should be connectedbetween the KD-1 and the speakersystems prior to applying ACpower to the unit. When a plug isinserted into the external speakerjack, the internal speaker is auto-matically switched off.Caution — The KD-1 should nev-er be operated into less than an 8-ohm speaker load.Input Level Selector [PAD]The slide switch provides 30dBattenuation for the 1/4" InputJack, and RCA pin Input Jack atthe "30dB" position.

天乐功放说明书篇一:功放使用说明书功放使用说明书该说明书为东莞市奇声电子实业有限公司版权所有目录一.面板按键功能说明---------------------------------- 1二.功能特性------------------------------------------3三.设置--------------------------------------------- 2四.播放----------------------------------------------3五.连接----------------------------------------------3六. 配置----------------------------------------------4七. 附录----------------------------------------------5八.使用注意事项---------------------------------------5篇二:功放的说明书说明书一、面板布置:1、本功放由功放、播放器、电平指示器、扬声器四个模块组成。

其中功放有放大音频信号的功能,可把播放器音频、外接音频、话筒音频信号放大,通过调节旋钮可改变信号的大小。

播放器有读取内存卡里的音频文件并转化成音频信号(另有收音机功能)的功能。

电平指示模块是通过计算音频信号,获取音频里音调的高低信号,再通过led灯显示出来,具有装饰的功能。

扬声器是把音频信号转化成声音信号的作用。

2、正前方:电平指示 1314⑥⑦⑧⑨⑩11 12①②③④⑤左声道右声道①电源指示灯、②音频输入、③音量旋钮、④话筒音量旋钮、⑤话筒输入、⑥播放器电源开关、⑦上一曲/音量-、⑧播放/暂停、⑨下一曲/音量+、⑩播放模式、11数据线插孔、12 usb插孔、13播放器显示屏、14 sd卡插孔(注:11、12、14插孔都是输入插孔,不能输出)3、正后方:变压器变压器线散热器遥控器电源线耳机插孔扬声器插头注意:1、使用前检查电源线和变压器线是否完好,外层绝缘皮是否有破损,若有破损则需要用电胶布粘住,防止皮肤接触而触电。

2、通电时最好不要触碰变压器和变压线。

3、使用时禁止触碰散热器、变压器,防止因温度过高而烫伤。

4、当使用耳机听音频时,只需把耳机插入耳机插孔,但要注意,在使用耳机之前要控制好音量,防止音量过大而损坏耳机。

一般操作是先把音量调为最小,插入耳机后再慢慢增大。

二、使用步骤:1、打开电源:在打开电源前先把音乐音量,话筒音量④调为最小,并确定自带播放器开关⑥处于关闭状态。

然后把电源线接电,则电源指示灯会亮①。

2、接音频:音频有两种,一种是外接音频输入②,另外一种是自带播放器输入,其优先级是外接音频输入高于自带播放器音频输入。

(1)外接音频输入需用一根3.5mm音频线与外界播放器连接,另外一端必须接到功放的外接“音频输入”②插孔,注意播放器的音量③应适当,否则将会烧坏功放芯片和损坏喇叭。

(2)自带播放器输入:首先把优盘或sd卡插入相应位置11、12、13,然后把播放器开关打开⑥,启动自带播放器。

利用红外线遥控或播放器上的按钮进行操作。

3、调节音量:找到音量旋钮(处正前方左端第一个旋钮③),顺时针方向旋转即为音量增大。

4、话筒的使用:话筒选用3.5mm插头的驻极体话筒,一般连电脑话筒都可以使用,不可使用其他话筒。

话筒插头必须插到“话筒输入”⑤,注意区分“音频输入”②插孔。

话筒音量也是瞬时针5、遥控器的使用:遥控器是采用红外线技术,通过编码和解码,进行遥控器和播放器之间的信息传递,其主要是遥控器对播放器的控制。

功能介绍:(1)播放/暂停⑧(2)上一曲⑦、下一曲⑨(3)播放器电源开关⑥(4)静音(5)六种音效(7)歌曲的选择(8)模式的切换⑩:播放优盘歌曲11、播放sd14卡歌曲、收音机。

6、能量灯显示:电平指示器采用独家生产的芯片控制,其根据音乐音频的高低而控制各列的显示个数,音调越高,显示的个数越多。

由于各列的敏感系数不一样,所以各列的显示是不一致的。

电平指示器有三种模式,三种敏感度,所以有九种不同的显示型式,通过电平菜单键即可改变显示型式(注:由于制作时间仓促,并没有安装电平菜单键)。

三、维护和开发1、维护:(1)使用前应把音量和话筒音量调为最小,然后再通电(2)使用自带播放器时先插sd卡或优盘,再打开播放器(3)远离水源,尽量不在潮湿的空气中使用(4)环境温度过高时,不可使用过长时间(5)尽量不常时间大音量使用(6)尽量不触摸电平显示灯,防止损坏(7)禁止压喇叭的振动膜(8)轻拿轻放2、各部分模块设计图各图和实物有所偏差,以实物为标准。

2、开发:此功放有很多地方还没完善,其中:收音机功能:添加天线。

电平指示模式的切换:添加电平指示菜单按键,按键两端分别连接电平芯片的6引脚和1引脚。

扬声器指示灯:扬声器指示灯线和扬声器插头并在一起,白色的线是led灯的负极,应接在带c的引脚上,而正极则应接在带r的引脚上。

电源指示灯:重装一个指示灯,把灯夹在孔中。

由于内部布线较多,如要拆卸,请认真研究内部结构后再拆卸!廖黎明制作篇二:3u功放机说明书篇三:功放说明介绍1:功率放大电路的基本要求介绍2:各类功率放大电路的结构特点甲类功率放大电路最初的功放为甲类功放,这类功放的功放管的工作点选在管子的线性放大区,所以就算在没有信号输入的情况下,管子也有较大的电流流过,且其负载是一个输出变压器,在信号较强时由于电流大,输出变压器容易出现磁饱和而产生失真,另外为了防止管子进入非线性区,此类放大器往往都加有较深度的负反馈,所以这种功放电路效率低,动态范围小,且频响特性较差。

输入用电容替代 15w纯甲类功放电路图乙类功率放大电路甲乙类功率放大电路otl的功率放大电路为此人们又推出了一种称为otl的功率放大电路。

这种电路的形式其实也是一种推挽电过是去掉了两个变压器,用一个电容器和输出负载进行藕合,这样一来大大的改善了功放的频响特性。

晶体管构成的功放电路有了质的飞跃,后来人们又改良了此种电路,推出了ocl和btl电路,这种电路将输出电容也去掉了,放大器与扬声器采取直接耦合方式,直到现在由晶体管组成的功放电路,其结构基本上是ocl电路或btl电路。

ocl电路与otl电路不同之处是采取了正负电源供电法,从而能将输出电容取消掉。

btl电路是由两个完全独立的功放模块搭建组成,如图c所示。

ic1放大输出的信号一部分通过ic2反相输入端,经ic2反相放大输出,负载则接在两放大器输出之间,这样扬声器就获得由ic1和ic2放大相位相差180度的合成信号了。

ui 篇四:a-100功放操作使用说明书a-100 多功能立体声音频功率放大器操作使用说明书欢迎选购中大音响的 a-100高保真音频放大器。

经过我们的精心设计,本品能产生无与伦比的超值享受,同时还能高保真的再现您所喜爱的音乐。

为了确保您能熟悉本品提供的功能,我们建议您在安装和使用前,请仔细阅读本说明书的内容。

产品介绍:这个功放的大致架构就是专为了整合pc-hifi而设计,近年来随着电脑和互联网的普及,丰富的网络资源,免费的网络音乐共享,让我们的生活越来越离不开电脑了,然而,普通的电脑硬件加上普通的有源电脑音响也就不能满足人们对高品质音乐的需求了。

pc hifi也就应运而生了。

何谓pc hifi?实际上就是撇开电脑本身的集成声卡,利用数字信号传输音源到外置声卡或者- 2 - 解码器作为高品质音源,再由专门的功放驱动音箱,这样声音效果相比普通电脑的有源音响就有了质的提升。

中大音响的a-100就是在这样的大环境下立项的,这个项目的解码部分将采用最经典的数字芯片加上专门为之独特设计的外围及后续电路,把来自电脑usb的音源转换成高品质高保真音频模拟信号,传送给功率放大电路进行足功率放大后驱动音箱,还原高素质音乐。

功放电路将采用中大独自开发的经典电路,每声道一对大功率irfp240/9240做为后级放大,这个管子非常好声,素有甜美、厚声之美誉,曾经被pass先生在他的很多机型上应用,也被无数pass迷所采用。

本功放的设计最大功率80瓦,峰值功率达100瓦,驱动一般的书架音箱组建高素质的pc hifi非常合适。

中大音响在设计上从来都是不惜成本的,就连一个旋钮都是特殊定做的铝合金喷砂旋钮,非常发烧高档,a-100高保真放大器采用中大音响自主设计并开模冲压的纯铝合金拉丝氧化机箱,非市面那些型材拼凑,底板厚度达到4mm,功率管直接安装在底板上进行散热,热稳定性非常高,这样的设计可以保证整机功放管始终工作在一个非常一致的温度范围上,为充分发挥管子的特性奠定了基础。

变压器是功放的动力之源,他的好坏直接关系到声音的好坏,a-100搭载了国际知名音频变压器制造商伊戈尔特殊定制的环形音频专用牛,并不惜成本加装钢带屏蔽,杜绝丁点漏磁对信噪比的影响。

专用软件仿真设计和多次实际打板调试,完全对称的发烧级pcb布线,紧凑考究的器件摆位将各种串扰降低到最低,更是采用高精度五色环金属膜电阻确保各级工作点的稳定,高达13600uf的大水塘电容确保大动态下仍然稳若泰山,严格配对安装的晶体管确保信号的丝毫不差,发烧级音频专用电容完美校声,全能保护电路采用goodsky音频专用继电器确保输出无瓶颈,具有过载、过压、过流、输出短路、直流输出等保护,特殊定做的音频专用12mm电位器耐用又好声,高质量镀银机内信号线做无损信号传输,无氧铜输出线和高级纯铜镀金输出端子确保功率信号畅通无阻,很显然高质量的元器件确保了线路性能的优良发挥,想不好声音都难! a-100高保真放大器分为标准版和usb版,标准版和usb版所有配置完全一样,只是标准版不配置usb解码版,标准版适合已有外置高品质声卡、解码器或者使用cd机做音源的用户;usb版适合只有一台电脑的用户组建pc_hifi系统。

a-100高保真功放整体声音表现平衡且富有一种贵气,非常全面的一种声音,中高频解析力高,低频干净有力,量感十足,久听不吵,非常适合近场监听,绝非那些炒作的天花乱坠的数字功放所能比拟。

特别搭配以中大自主研发生产的音箱,更是如鱼得水,无论是听人声还是乐器,无论是听舒缓还是劲爆,无论是听古典还是流行,都能给你还原的淋漓尽致。
