Ashly FX系列DSP功能强大的音频放大器说明书
FX 500 Front PanelFX 60 and FX 125 Front PanelThe FX series is a range of multi-purpose installationDSP-equipped amplifiers. The FX series amplifiers feature a built-in Wireless-Access-Point (WAP) for simple connection and configuration via WiFi as a well as an intuitive web-based software UI. With 6 models to choose from starting at 2 x 60W in a half rack unit to 4 x 500W in a two rack unit, there’s an FX that will fit just about any project.Naturally, they have the rugged reliability that Ashly is known for…including a 5-year warranty.TECHNICALSPECSonPAGE FOURFX SeriesDSP Power A mplifiers with intuitive web-based software UI and built-in WiFi for convenient connectivity and configuration.❚Conference/Huddle Rooms ❚Classrooms ❚Retail Stores ❚Hotel Lobbies❚Inside Displays & Kiosks ❚Bars and Restaurants ❚Trade Show Exhibits ❚HoW & AuditoriumsFX 60 and FX 125 Front PanelFX 500 Front PanelFX 500.2 – Back FX 500.4 – Back – Amplifier operational.– Standby Mode.– GPIO triggered Standby Mode– No input signal present.– Signal present on one or more inputs.– Signal limiting/clipping on one or more inputs.Off – No output signal present.Green – Signal present on one or more outputs.Amber – Signal limiting/clipping on one or more outputs.Red – One or more channel pair is in overload/protection mode.4-Channel Models– WiFi disabled. – WiFi enabled– No Ethernet network detected. – Network enabled– Ethernet network detected.AnalogAnalog AC receptacle100-240VAC 50/60HzInput/Output 2-Channel ModelsEach FX model offers a healthy compliment of IO (include Digital SPDIF In & Out) and programmable integration ports for remote Volume Control, GP triggers and more.FX is networkable via Ethernet for wired LAN connection, or via its built-in WiFi hotspot.

All of that is in one box.Page 3 of 4FX SeriesHigh-Density DSP Power AmplifiersIntelligent DSPTo control FX’s powerful DSP, you’ll find easy access to its intuitive and user-friendly interface via a simple web browser (similar to AquaControl). No software to install (it’s built into the FX unit).Just connect using the Ethernet port or built-in WiFi and you’re ready to Rock & Roll. The WiFi connection allows secure ID and password protection from unauthorized use and for more advanced users, Ethernet allows custom IP settings for use on a more complex wired LAN.The FX Series features a powerful DSP engine that canconfigure to suit virtually any task, without the need for additional equipment. From processing input sources, routing and output DSP that can fine tune the sound of any speaker. Everything you need is right there.

简洁20W单端纯甲类功放的制作电路图
简洁20W单端纯甲类功放的制作电路图这款20W单端纯甲类功放电路图，电路十分简单，所用元件很少。
符合“简洁至上”的原则,用料普通，易于仿制。
看到好多的发烧友对单端纯甲类功放感兴趣，不敢独享，与广大的音响发烧友交流。
原理图如下所示：电路原理和设计思路，整机电路可以分为四部分：输入级:核心电路是由两只BC559组成的差分放大电路，22K对地电阻为三极管的偏置电阻，它的大小同时决定了整个功放的输入电阻。
8.2K电阻是差分对管的公共发射极电阻，决定了差分电路的共模抑制比和本级的静态工作电流。
经过输入级放大的电流在流经1K可调电阻时产生的电压信号，直接输送到下一级。
1UF电容是整机的输入电容，其容量的大小和制造材料对音质的影响很大。
根据理论计算，1UF的电容与输入电阻22K组成了一个高通滤波电路，它的低端转折频率可以用下式计算：f=1000/(2*3.14*22*1)=7.2HZ。
（在过去将放大器的低端频响定位在20HZ时，还是可接受以的。
现在数码音源大行其道的今天，看来还是高了一些，低端转折频率定在1HZ以下还是可以接受的。
）由于该电容的重要性，一定要选择品质优良的进口音频专用耦合电容，在国产的电容中，新德克的品牌还是值得信任的，经过笔者和朋友的试用，效果令人满意，只是体积稍大了些，在设计电路板时要考虑是否能安装得下。
8.2K电阻决定了输入级的晶体管静态工作电流，可以由下式进行估算(两管值）：VCC/8.2K=20/8.2=2.4MA。
由于输入级的晶体管静态工作电流对音质有较大的影响，可以调整该电阻的大小来满足自己的要求。
（晶体管静态工作电流小，信噪比高，但是音质发干，低音单薄。
如果电流大一些，音质温暖，低音厚实，但是晶体管特有的高频噪声和反映在音频内的电流声也会增加，使信噪比下降。
本机取2.4MA还是比较合适的。
电压放大级：为了简化电路，本机使用一只三极管BD139，采用共射放大电路，还采用了自举电路。

雅马哈861功放说明书
雅马哈861功放说明书装载有只在{dj0}机型才被应用的ABT专业级视频处理组件、和ADI编码影像处理电路，能将普通DVD视频升级到720p/1080i高清格式而实现逐行扫描输出。
此晶片内含有很多崭新技术，光是处理隔行至逐行扫描过程便是以点(pixel)为转换单位，画面亦有效减少狗牙现像出现。
而且该I/P转换电路更是基于精密视频缩放引擎，它能够独立进行图像的水平和垂直缩放，以达到高清晰分辨率视频显示的优秀的图像质量。
功率放大器部分，为105 W×7 ch(6Ω )的定额输出，采用了新的"高驱动力"放大电路的组件设计，提供有效的喇叭驱动能力。
在放大器的部分加入了众多新鲜的元素，例如特别装置了动态声道分配DSP，但用家不需要用到7声道放大那么多、只需要5.1声道的时候，用家可以将辅助环绕的输出连接到前置喇叭的高音、原来前置的输出连接到喇叭的低音，做"双功放"的高音质输出，让声音效果更佳。
除了对应7.1声道的放大电路更配合有平衡功率分配设计，让用家在使用2声道欣赏立体声音响的时候，获得更充足的功率驱动能力和更好的声音品质。
作为一台中高级的AV机，除了AV重播效果的出色外，HIFI音响的播放也提供不俗的配置。
对应现在的宽频DVD-A及SACD的高音频播放要求，频率特性为10 Hz-100 kHz（0/-3 dB）。
而且特别加入了对应MP3、WMA等压缩音乐的高低音扩张校音电路，能让MP3、WMA的播放音质更好，听起来更舒服。
具有"纯直通"的设计，这里说的直通除了CD播放的模拟信号直接进入功率放大输出部分外，在数码输入如SACD的DSD或者PCM 数码信号的时候，同样会直通，会停止所有不需要的DSP芯片组、视频处理电路等的电源，而且用作缓冲记忆的RAM组也会停止工作，以防止存储/读取过程中使误码率增加。
数码信号直接传输到DAC解码部分做解码能避免信号经过不相干的缓冲内存、环绕、解码等电路而产生的微小损失，让数码信号直接解码后直接进入功率放大输出部分，以提供高品质的HIFI重播能力。
