Development of Transistor Power Amplifiers and Intermodulation DistortionWith the gradual maturity of semiconductor technology, the varieties of high-current and high-voltage transistors are increasing day by day, and more and more power amplifiers use OCL circuits or OTL circuits without output tra

Is it better to choose active speakers or passive speakers?The difference between active speakers and passive speakersFirst of all, let's figure out the concept of active speakers and passive speakers. Active speakers refer to speakers with built-in power amplifiers, also known

1. 成本低，价格极易被接受 独立的外置功放的机壳应该具备足够的机械强度并有良好的屏蔽性，一些制造精良的机壳的成本往往达到总成本的15～20%。有源音箱的功放设置在音箱内部，比功放要少一套机壳，成本得以大幅降低。在功放电路方面，外置功放一般采用分立元件，音质较好但成本较高，且安装调试复杂，生产难度较大。而有源音箱一般采用功率集成电路，价格低，设计简单，一般无须调试，而且保护功能齐全，容易大批量生产。这使有源音箱的成本进一步降低。在线材方面，优质音响线材的价格是相当昂贵的。有源音箱只需一根喇叭线，而普通音箱至少需要一对，这又使有源音箱的成本降低不少。 2. 连接简单，使用方便 有源音

Advantages and disadvantages of active speakers and passive speakers1. What is an active speaker? What is a passive speaker?Active speakers: Active speakers are also called "active speakers". It usually refers to speakers with power amplifiers, such as multimedia computer speakers, active subwoofer

active speaker1. The price is relatively easy to acceptThe casing of an independent external power amplifier should have sufficient mechanical strength and good shielding performance. The cost of some well-made casings often reaches 15-20% of the total cost. The power amplifier of the active speaker

How to use active speakers correctly1. connect Before purchasing an active speaker, you need to see the input interface on the back of the speaker. For civilian-level active speakers, generally only RCA interfaces are provided, and a few high-end m
