运放型号后不同的后缀是什么意思
[基础知识] (转)经常看到运放型号后不同的后缀是什么意思!买家：经常看到运放型号后不同的后缀是什么意思？比如OPA2604AP和OPA2604AU AD827JN和AD827AQ有什么区别呢？专家：一般来说IC型号的后缀代表同一型号产品，不同的封装和性能上的一些差异。
买家：哪常见的后缀是什么意思？*** 对于BB公司的运放（通常以OPA字母开头比如OPA2604AP）常见的有AP、BP、AM、BM、SM、KP、AU(UA)、KU、SG，其中第一个字母A、B、K、S代表运放的性能等级(温漂，零漂等等)，可以简单的理解为，K是低温低精度，S是高温低或高精度(具体型号定义不同OPA111SM是高温标准精度、OPA620SG是高温低精度，OPA627SM是高温高精度)，A是标准精度，B是最高精度。
第二个字母，P、M、U、G是封装形式，P代表DIP双列直插塑封，M是TO-99金属封装，U是SOIC双列贴片塑封，G是双列直插陶封金顶。
*** 对于AD公司的运放（通常以AD字母开头，比如AD827JN）常见的后缀有JN、JR、KN、KR、AN、AR、BR、AQ、BQ、CQ、SQ、TQ，其中第一个字母J、K、A、B、C、S、T代表精度性能等级跟BB公司的含义是一样的，其中按性能排列 J<A<S<K<B<T<C。
第二个字母，N、R、Q代表封装形式，N代表DIP双列直插塑封，R代表SOIC双列贴片塑封，Q代表双列陶瓷封装。
一些分析和思考通过以上介绍有心的烧友可能会发现，两个公司的封装代码并不尽相同，对于BB公司的运放来说其并没有常说的所谓陶瓷封装运放，只有G型的金顶陶瓷封，而该封装现在已经被金封代替，像OPA627BM（To-99金封最高精度）OPA111SM（T0-99封装金封最高耐温标准精度）。
而市场上常见的陶封OPA2604AQ显然就是假货了，因为BB公司没有Q型封装，它是AD公司的封装形式。
声卡打磨的各类运放终极教程
声卡打磨的各类运放终极教程第一篇：听感1、运放这东西还是不错的，玩起来比较简单又很有效果2、实际上到了2604这一级别，解析力、音场、音乐性等各项指标也都相当不错了，高档运放都很有特点，主要还是看自已的音乐口味来选择3、先后去了几个地方测，不同的功放测的感觉不全一样，看来电路设计还是最重要的，我朋友的一台英国CD机声音很好，就是用八片5532组成运放的。
4、搭配很重要，我自已有个斯巴克CD机和AD10的耳机（声染很重），又浑又厚高频还刺耳平时怎么听都不是味，已闲置很久了，于是把手上的运放挨个组合测试，拆腾了一晚上，最后CD机的两个2604换成了DY649，耳放上5532换成了712（1057也可以），再听耳机，清淅、透明，细节丰富、低音有力，特别是人声部份非常突出。
感觉变了一副耳机。
借了朋友的K501试，则感觉827+DY649组合最好。
5、总想找更高档的运放，试试更好一点的效果，为了这种感觉而导致付出实在太多的精力。
呵呵，没人能说明原因，如果真要说给个理由的话，那只能告诉这是一种精神上追求。
一种心境渴望。
一种灵魂寄托。
一永恒永恒的感觉。
高品质的享受。
第二篇：简介热门运放：近段时间身边几个朋友玩了音响又开始迷上了磨机换运放，CD机、功放，连电脑上声卡也弄个827、275什么的。
所以周末，特意去拿了堆运放回来测试，简单谈谈感受吧。
NE5532：确实有点胆味，解析力一般，高频比较燥，低频比较糊且肥。
价廉物美足已弥补一切!op275：和5532比，胆性还重一点，解析力、低频、音场更好一点，可以买贴片的来打磨声卡用（特别是创新的），可以改善硬冷的数码声。
EL2244：音色中性，音场比较宽，高频还可以，中频音乐味差，有人说解析力很高，其实是因为低频量感少，中频薄，高频显得突出而已。
要用好比较难。
LT1057：两端延伸不错，速度、动态和解析力也挺好，就是属冷色调，放出的音乐好象有种不食人间烟火的味道，让你可以静静的听，却燃不起对音乐的那份激情。

System Requirements◊ The UCA202 is PC and Mac-compatible. Therefore,no installation procedure or drivers are requiredfor the correct functioning of the UCA202.To work with the UCA202, your computer must fulfillthe following minimum requirements:2.1 Hardware connectionUse the USB connecting cable supplied with the UCA202to connect the unit to your computer. The USB connection alsosupplies the UCA202 with current. You can connect a varietyof devices and equipment to the inputs and outputs.3. Operating Elements and Connections3.1 Front panelFig. 3.1: Front panel UCA202(1) The LED indicates the status of the USB power supply.(2) DIGITAL OUTPUT : The Toslink jack carries an S/PDIF signalwhich can be connected via a i ber optic cable, for example, to the digital input of an effects device.(3)Use the jack to connect a standard pair of headphonesequipped with a 1/8" TRS connector.(4) The VOLUME control adjusts the volume level of theheadphones output. Turn the control fully to the left before you connect the headphones. This helps you avoid the damage that is caused by high volume settings.3.2 Rear panelFig. 3.2: Back of the UCA202(5) Use the jack to connect a standard pair of headphonesequipped with a 1/8" TRS connector. (6) Use the LINE-OUT jacks for audio cables with RCA connectors.(7) Use the LINE-IN jacks for audio cables with RCA connectors.(8) The OFF/ON-MONITOR switch activates the monitorfunction. In this case the input signal is routed directly to the headphones output.4. Working with the UCA2024.1 Application example ArrayFig. 4.1: Common version with the UCA202To provide a professional recording interface between mixing console and computer, you can use the UCA202 in combination with a suitable mixing console that includes subgroup outputs. This type of setup allows you to record several signals in the computer at the same time, to simultaneously play back several takes or playbacks which have been recorded, and to listen to the whole recording via loudspeakers (or headphones). Figure 4.1 shows a possible setup with one UCA202.Connect the outputs of the subgroup (in this case ALT 3-4 OUT)with the inputs of the UCA202 (6). You can choose to connect the outputs (5) of the interface either to the TAPE INPUT sockets or to your monitor speakers. You can connect control headphones to the socket (3) of the UCA202 or to the headphones output of your mixing console. Use the USB cable supplied with the unit to connect your PC or MAC via the USB interface.By routing each channel that you want to record through the ALT3-4 subgroup, you can now use the input channels of the mixing console to record different signals (e.g. microphone, guitar, sound module, etc.) in the computer. If you connect the OUT jacks of the UCA202 to channel inputs 7/8 (not via TAPE INPUT), make sure that the signal is not switched to the subgroup but instead to the main output of your mixer (MUTE key on the UB1204FX-PRO in channel 7/8 not pressed). Otherwise feedback can occur. Make sure that you use the SOURCE section on the mixing console to select the correct monitoring paths (ALT 3-4 and MAIN MIX or ALT 3-4 and TAPE).If you lead the UCA202 back via a channel input (not TAPE INPUT), you can also use the aux path in the channel to set up a monitor mix for live musicians. To do this, use the Aux Send (e.g. Aux 1) in this channel input. If the musicians want to hear themselves as well as the playback or previous recording takes, use the Aux Sends in the recording channels to mix in the recording signals with the monitor mix.5. Audio ConnectionsAlthough there are various ways to integrate the UCA202 into your studio or live set-up, the audio connections to be made will basically be the same in all cases:5.1 WiringPlease use standard RCA cables to connect the UCA202to other audio equipment. You can also use an adapter cable.Fig. 5.1: RCA cableFig. 5.2: Adapter cable with ¼" jack5.2 Headphones connectionThe UCA202 is provided with a headphones jack. Here, you can connect any standard pair of stereo headphones with a 1/8" TRS connector. 6.

关于车载电台的选购
关于车载电台的选购一、车载电台的选购原则：1、车载电台的特点：关于车载电台与手台的区别以及车载电台的分类，我们将在另外的帖子里详细讨论。
在此，我们只简述一下适合我们车腿使用的车台的特点：A、功率大，通联距离远。
目前市场上适合我们车腿使用的车台在70厘米波段的发射功率一般在25-50W之间，比手台要大很多倍，通联范围也相应增大很多。
B、功能强大，技术指标好，坚固耐用。
一般车台都具有很多的实用功能，使用上方便灵活。
同时他们的技术指标和质量也高于一般手台（主要指国产手台），使用寿命很长。
C、固定安装，可以在车辆、家庭和办公场所使用。
车载电台不便于随身携带使用，适于在车辆和房间内固定安装使用。
D、需要大功率专业电源供电。
车载电台一般需要专业通讯电源提供13.8V的直流电，供电电流一般应大于20A。
在车内安装时可以直接接在12V汽车电平上使用。
E、车载电台自身不配备天线，但可以接驳任何类型的天线。
F、双段和多段车载电台一般具有很宽的接收范围和双段/多段发射能力，可以监听许多频段。
同时他们中大多数还具有双监听/双显示功能。
G、新一代的车载电台一般都具有机身/面板分离功能，可以方便地在车内任何地方安装、使用。
2、我们车腿的一般选购原则：A、具有业余无线电爱好者可以使用的收发频率范围。
比如，单段车台要能够在430-440MHZ的频率范围内收发。
当然如果是双段车台要可以在U/V段具有收发功能。
B、接收灵敏度好。
C、操作简便、使用灵活。
可以手制频。
D、适合的发射功率，一般在25W以上。
E、在较高的性价比范围内，具有尽量多的使用功能和好的应用口碑。
F、最好支持上中继、亚音、差转功能。

音箱运放分类
入门级：ne5532:曾经被誉为的运放之王！声音温暖.有多个版本选择其中大S的5532an最好ti的5532P最差！最基本的声音高音暗色.中频比较宽但肥.厚低频干而且实!声音略糙一点。
听过好的运放再听它就不想再用了！但是唯一的优势就是音乐味道很浓且价格便宜这样的经典比烂4558好太多了。
无什么要求的一粒大s解决问题！tl072，TL082D:来自久远历史的运放！高频明亮且有点失真！中频醇厚。
低频稍少音色一般对机子要求较高！三频分不清。
没有层次jrc2114：同tl82d差不多个人觉得效果比tl82还差点！醇厚圆润，但高频有衰减，没有明显的延伸，听起来有点不自然，而且2114最大的缺点是大动态混，正是这点让人感觉非常不爽。
音色不错有一点点点甜的味道。
低频少！三频乱！听耐了会觉得是噪音而不是音乐！jrc4580：和ne5532音色相差不大.个人认为效果一般不作详评！lm833n：开始听这个效果不错啊。
底蕴是所有运放中最厚的听起来三频有点干的感觉。
声场宽！中音还不错。
高音明亮且粗（相对好的来说）！细细听下找不到其他缺点！便宜的好东西跟ad712差不多。
声音比较耐听！pmi op07cm：这是一颗用作缓冲上的运放用在音色上好像还不错、单运放。
声音有点粗三频中低频很厚！高频一般！像是运放op42aj的降频版本！比起其他的入门好一点。
美国味道的声音。
相对这个价位的运放比较值得！pmi op275g：这个有两个版本1996年前pmi货和之后的ad货！各有特点，暖暖的声音人声亲近。
像是5532的开阳版本！ad出产的高低音不错特别是低音厚中音有点薄但是影响不大！空气感好！pmi的高音甜美中音与高音配搭不错！低音稍少！声音清晰！机子材料用得好的话和ne5532搭配出来效果比opa627出来声音还好听！属于入门级比较耐听的运放！无大要求够用了！pmi op285g：网上有些资料说它跟op275G效果一样！只是op275是高失真的版本而而。

计算机网络常用端口
计算机⽹络常⽤端⼝⽬录（20190525添加：Linux系统nftables防⽕墙的端⼝映射章节）传输层的端⼝计算机之间依照互联⽹传输层TCP/IP协议的协议通信，不同的协议都对应不同的端⼝。
并且，利⽤数据报⽂的UDP也不⼀定和TCP采⽤相同的端⼝号码。
TCP和UDPTCP（Transmission Control Protocol，传输控制协议）是⾯向连接的协议，也就是说，在收发数据前，必须和对⽅建⽴可靠的连接。
UDP（User Data Protocol，⽤户数据报协议）⾮连接的协议，传输数据之前源端和终端不建⽴连接，尽快交付，不保证可靠交付。
> TCP就好⽐打电话: 可靠，相对消耗资源也更多.拨通电话，且对⽅接听了电话，才算建⽴连接成功，这时候就可以聊天了。
TCP数据才开始发送。
电话拨通了，但对⽅没接，建⽴连接失败；需要重拨...若中途掉线，即连接断开，聊天也中断了。
连接断开；需要重拨...> UDP就好⽐发送短消息: 快速节能但不可靠.只管发出去，不管对⽅能不能看到。
更不会考虑对⽅是否有拦截短信等软件。
对⽅没带⼿机，⼿机没电关机...与我⽆关，我已发送完成。
端⼝号的分配端⼝号基于三个范围以各种⽅式分配。
这些范围的差异⽤途描述于[RFC6335]。
根据[RFC6335]的8.1.2节：系统端⼝:（0-1023）是由“IETF审查”或“IESG批准”程序分配[RFC8126]。
⽤户端⼝:（1024-49151）由IANA使⽤“IETF审核”流程分配，根据“IESG批准”流程或“专家审核”流程[RFC6335]。
动态端⼝:（49152-65535）或称私有端⼝, 根据定义，没有端⼝可以被正式地注册占⽤。
⼴泛公认的端⼝列表1. ⼴泛公认的端⼝，是⼤部分⼴泛使⽤的程序或协议的默认端⼝，但实际使⽤时，由于安全等原因，系统管理员可以⾃⾏指定端⼝号。
2. 这⾥的端⼝号通常指的是服务器端的端⼝号。

PAC2M主机快思聪
PAC2M主机相对于P A C2主机而言是一款紧凑形的，低成本的灯光控制和自动化控制主机。
尺寸是PAC2主机的一半，PAC2M主机非常适合于公寓和家庭使用，也适合于单独的会议室和演讲会堂。
2系列控制系统——基于可靠的快思聪2系列控制引擎，基于快思聪强大的开发软件和海量的设备驱动和软件模块数据库，PAC2M具有广泛的应用编程空间。
PA C2M可以和快思聪全系列灯光调节模块、窗帘控制模块、按键面板、触摸屏、温控器、无线网关和扩展模块进行无缝连接。
整体家居的集成——通过P A C2M主机的控制功能，PAC2M提供了非快思聪的设备和子系统集成功能。
内置的4个独立的继电器和4个数字输入端口可以用于移动探测器、接触器、门控器和其它低压控制。
通过可安装在居住和商业环境任意位置快思聪扩展模块，可增加附加的继电器、I/O端口、RS-232、RS-422、R S-485、IR、MI DI、串口、D T MF（双音多频D ual Tone Multi Fr equency）界面和窗帘控制器。
模块式安装——PAC2M是被设计安装在快思聪CAE N自动化安装箱内的，并且提供一个直接的系统总线给C LXI系列灯光控制模块。
在没有快思聪自动化安装箱的条件下，PA C2M也能直接的安装于合适的板面。
每个快思聪灯光系统完全模块化和规模化，允许实际性的无限配置和灵活扩充。
C re sn et分配——C re sn et是快思聪灯光模块、墙面调光器、温控器、按键面板和其它许多设备通信的主干线。
快思聪灯光控制系统采用灵活的4线制总线。
PAC2M主机通过32个独立的Cresn et 端口和众多的Cre snet设备相连接。
内置的C resne t集线器提供8个独立的段，每个段的布线距离可达到900米，大约可以连接25个C re sn et总线设备。
两段Cr es net端口通过两个独立的电源组进行供电，供给洁净的、稳定的24V DC电源。
常见的网络服务端口
常见的⽹络服务端⼝常见的⽹络服务端⼝⼴泛公认的端⼝列表1. ⼴泛公认的端⼝，是⼤部分⼴泛使⽤的程序或协议的默认端⼝，但实际使⽤时，由于安全等原因，系统管理员可以⾃⾏指定端⼝号。
2. 这⾥的端⼝号通常指的是服务器端的端⼝号。
⽐如⽹页浏览器会在本机的36406端⼝和远端的80端⼝间建⽴连接。
服务端的80端⼝就是默认的⼴泛公认的端⼝。
⽽本机的36406则只是临时端⼝。
端⼝0-1023是公认端⼝号，即已经公认定义或为将要公认定义的软件保留的，⽽1024-65535是并没有公共定义的端⼝号，⽤户可以⾃⼰定义这些端⼝的作⽤。
那么端⼝号到底有什么作⽤呢？当⼀台电脑启动了⼀个可以让远程其他电脑访问的程序，那么它就要开启⾄少⼀个端⼝号来让外界访问。
我们可以把没有开启端⼝号的电脑看作是⼀个密封的房间，密封的房间当然不可能接受外界的访问，所以当系统开启了⼀个可以让外界访问的程序后它⾃然需要在房间上开⼀个窗⼝来接受来⾃外界的访问，这个窗⼝就是端⼝。
那么为什么要给端⼝编号来区分它们呢，既然⼀个程序开了⼀个端⼝，那么不是外部信息都可以通过这个开启的端⼝来访问了吗？答案是不可以。
为什么呢？因为数据是⽤端⼝号来通知传输层协议送给哪个软件来处理的，数据是没有智慧的，如果很多的程序共⽤⼀个端⼝来接受数据的话，那么当外界的⼀个数据包送来后传输层就不知道该送给哪⼀个软件来处理，这样势必将导致混乱。
源端⼝号⼀般是由系统⾃⼰动态⽣成的⼀个从1024-65535的号码，当⼀台计算机A通过⽹络访问计算机B时，如果它需要对⽅返回数据的话，它也会随机创建⼀个⼤于1023的端⼝，告诉B返回数据时把数据送到⾃⼰的哪个端⼝，然后软件开始侦听这个端⼝，等待数据返回。
⽽B收到数据后会读取数据包的源端⼝号和⽬的端⼝号，然后记录下来，当软件创建了要返回的数据后就把原来数据包中的原端⼝号作为⽬的端⼝号，⽽把⾃⼰的端⼝号作为原端⼝号，也就是说把收到的数据包中的原和⽬的反过来，然后再送回A，A再重复这个过程如此反复直到数据传输完成。
几款发烧运放听感测试报告
几款发烧运放听感测试报告几款发烧运放听感测试报告写在前面的话：5年前写的了，现在翻出来，还是觉得有些小用，正好朋友聊起，就发了。
陆续用了一个月多时间，前后间隔三个呀，写下一些文字，名为运放听感测试报告。
虽然希望尽力给爱摩机的朋友带来一点参考，但是设备极其有限、器材相当匮乏，所以更多的也只能是一种基于爱好的相互交流。
说起来难以使人相信，从2001年入手帝盟S100开始算作发烧初始，但是一直没有真正像样一点儿的器材。
07年6，然后11月入手乐之邦玲珑3纪念版，于是一发不可收拾，接着入手HIFIDIY MINI USB DAC，再接着是甩二——我不可挽回的中毒了，为了使MINI SUB DAC和甩二工作得更好，我玩起了运放……在各类发烧器材店蹭听总计不到10小时算是熟悉器材。
08年8无损成为这次测试的音源。
本次评测目的是理性了解各个运放的特点，因此，测试者的主观认识、测试条件，就像物理学里的参照系一样重要。
所有评测以HIFIDIY MINISUB DAC增强电源打摩版（将数字、模拟部分共7粒nichicon 滤波电解换为思碧轴向钽电解电容）为基准设备，DAC的I/V变换、LPF和放大同时使用相同的两对OP，并参考用作甩二SE输出运放的表现。
基准测试器材是ThinkPadT61+HIFIDIY MINI USB DAC+HD590，参考测试是台电T39+StreetWires ZN73.5toRCA+SXT-2+HD590&foobar0.955+帝盟S100+StreetWires ZN73.5toRC+SXT-2+HD590，搭配性测试器材是森海MX760、达音科S01、舒尔E4C、EC700 by lilelelee。
播放器为foobar0.955中文版，插件为音源为60%的人声、30%的器乐、10%的交响和古典，第一次随机选取，以后每次按第一次播放列表顺序播放。
所有评测均有相当音量（终端输出器材的音量均在8点到11点）以保证足够的声压，并用DT9205A万用表测量，使得每次同一终端输出器材1KHz下开环输出电压一致。
