Active Speaker Exploration (1) Talking about the Advantages and Disadvantages of Electronic Frequency Division and Power Frequency Division
The frequency divider used in the audio circuit is actually a filter in the electronic circuit. The filter is an electronic device that can pass the useful frequency signal to suppress (or greatly attenuate) the unwanted frequency signal, classify and filter according to the processed signal type. The device can be divided into two categories: analog filter and discrete filter. The analog filter can be divided into three categories: active, passive and heterogeneous. The discrete filter is divided into three categories: digital, sampling and mixing. The majority of the dividers used are analog filters.
Electronic frequency division is also known as pre-stage frequency division and active frequency division, and is widely used in audio products. In the past two years, the number of civilian 2.0 speakers using electronic crossover has increased, and the electronic crossover technology has become a hot topic. In the cognition of electronic crossover, many people have certain misunderstandings and deviations. Here we Focus audio puts forward its own views, and hopes to throw a brick into the jade, which can lead to everyone's discussion.
In the past two years, the civilian 2.0 speakers using electronic crossover have gradually multiplied D1080MKII
Dividers for active speakers can be divided into traditional power dividers (between the amplifier and the speaker unit, processing power signals) and electronic crossovers (before the amplifier circuit, processing small signals). The electronic frequency division is essentially a high- and low-pass filter. The electronic filter is not a new technology or a cutting-edge technology. It has been widely used in the 1960s and has achieved remarkable development with the development of operational amplifiers. Today, electronic filters have been widely used in every corner of our lives.
The common electronic crossovers on active speakers are generally high- and low-pass filters or band-pass filters, divided into active and passive. Power dividers are passive filters composed of L, C, and R. Device.
