Tube amplifiers work under high voltage and low current conditions. The plate voltage of the final power amplifier tube can reach 400-500V or even thousands of volts, while the current flowing through the tube is only tens to hundreds of milliamperes. The input dynamic range is large and the convers

The difference between tube power amplifier and transistor power amplifierAccording to the different types of power amplifier tubes, power amplifiers can be divided into tube power amplifiers and transistor power amplifiers. As early as the 1960s, tube power amplifiers had been popular al

The power amplifier was independent before, and later, the power amplifier was integrated into the speaker. Now, the power amplifier is independent again!The development of each product has its own trajectory. Understanding the development process of the power amplifier is very helpful for us to cho

Questions about vacuum tube amplifiersVacuum tube amplifiers are a fascinating thing, as many old audiophiles like vinyl systems, they are very flexible. We sort out the questions that most people have and share them with you! Tube machine to warm up?In fact,

Know what is a power amplifier from scratchA power amplifier is a machine that amplifies a small signal to drive a speaker to emit sound. In the field of home audio, it can usually be divided into a preamplifier, a power amplifier and an integrated amplifier.After receiving the signal amplified by t

立体声，就是指具有立体感的声音。自然界发出的声音是立体声，但如果我们把这些立体声经记录、放大等处理后而重放时，所有的声音都从一个扬声器放出来，这种重放声(与原声源相比)就不是立体的了。这时由于各种声音都从同一个扬声器发出，原来的空间感(特别是声群的空间分布感)也消失了。这种重放声称为单声。如果从记录到重放整个系统能够在一定程度上恢复原发生的空间感(不可能完全恢复)，那么，这种具有一定程度的方位层次感等空间分布特性的重放声，称为音响技术中的立体声。 组成成分直达声直达声是指直接传播到听众左右耳的声音反射声它是指从室内表面上经过初次反射后，到达听众耳际的声音，约比直达声晚十几到几十毫秒
