Sound intensifiers are at the very heart of each home theater framework. As the quality and yield control prerequisites of the present amplifiers increment, so do the requests of sound amps. It is difficult to pick a speaker given the expansive number of models and plans. I will clarify the absolute most basic enhancer structures, for example, tube amps, direct amps, class-AB and class-D just as class-T amps to enable you to see a portion of the terms normally utilized by speaker producers. This guide ought to likewise enable you to make sense of which topology is perfect for your specific application.
Basically, the reason for a sound intensifier is to change over a low-control sound flag into a powerful sound flag. The powerful flag is sufficiently expansive to drive a speaker adequately boisterous. So as to do that, an amp utilizes at least one component which is constrained by the low-control flag to create an expansive power flag. Cylinder enhancers used to be basic a couple of decades back. A cylinder can control the present stream as indicated by a control voltage which is associated with the cylinder. Shockingly, tube speakers have a genuinely high measure of mutilation. In fact talking, tube intensifiers will bring higher music into the flag. Be that as it may, this normal for cylinder amps still makes these well known. Numerous individuals portray tube amps as having a warm stable versus the virus sound of strong state amps.
Another downside of cylinder amps, however, is the low power proficiency. Most of intensity which tube amps expend is being dispersed as warmth and just a division is being changed over into sound power. Likewise, tubes are very costly to make. In this way tube amps have for the most part been supplanted by strong state amps which I will take a gander at next. Strong state amps supplant the cylinder with semiconductor components, normally bipolar transistors or 音響回收. The most punctual sort of strong state amps is known as class-amps. In class-An amps a transistor controls the present stream as per a little dimension flag. A few amps utilize a criticism component so as to limit the symphonious mutilation. Class-amps have the least twisting and as a rule likewise the most reduced measure of clamor of any speaker design. On the off chance that you need ultra-low contortion, at that point you should investigate class-A models. The principle downside is that like cylinder amps class an amps have low proficiency. Therefore these amps require substantial warmth sinks to disperse the squandered vitality and are generally genuinely cumbersome.
Class-AB amps enhance the effectiveness of class-amps. They utilize a progression of transistors to separate the substantial dimension signals into two separate territories, every one of which can be intensified all the more proficiently. 回收黑膠 amps are generally littler than class-amps. Be that as it may, this topology includes some non-linearity or contortion in the locale where the flag switches between those territories. Accordingly class-AB amps commonly have higher mutilation than class-amps.
