What is active and passive?

The words active and passive often appear in front of us. What are the terms such as active speakers, active preamps, active components, active crossovers, and passives? The so-called initiative has the meaning of autonomy, we separately study what is the difference between active and passive.
Active speakers are used by many people. The small speakers of the Walkman are active speakers. In addition, a set of amplifiers is added to the general speaker box. When we want to use it, we only need the front stage and not the rear. level. Like ATC's speakers, the active and passive models are produced. The active internal use of electronic sound distribution, and the need to match the appropriate post-level troubles; passive speakers are general speakers, which only have a sound network.
The active preamplifier is the IC, transistor, and vacuum tube pre-stage that we generally see. When the input signal is output, it has amplifying effect. This preamplifier can play a high dynamic performance, and the characteristics of each model are different. Tone. The passive preamp is the simplest, it is a volume control attenuator, its output will be smaller than the input, but the sound rendering is less, usually only a slight difference, not like the active preamplifier difference is quite large .
The active components, that is, the semiconductors we see in crystals, vacuum tubes, ICs, etc., have amplifying functions, and the passive components are components such as resistors, capacitors, and inductors. In the past, passive components were still underdeveloped. Everyone said that the quality of active components has the greatest impact, but today there are many types of passive components, Wima, ROE, Philips, Dale, Vishay..., just replace a capacitor, perhaps this preamp Or the sound of the latter level is completely different from the previous one. Do you say that the active component is important or is the passive component important?
The active split is the electronic split, the whole structure uses the electronic circuit to divide the full range into as many segments as the horn sound, and then separately zoom in; the passive split is simpler, which is the crossover inside the speaker. . No matter which one, the most important thing is to be able to divide the sound just right. The active splitting is to divide the signal into the high, medium and low grades in the original stage, and then input the independent post-stage amplification to each unit. The important thing is that the splitting circuit must achieve the efficiency of each section with the gain of the single unit. Flat, otherwise it may be worse than passive split.

Food Processors are multifunction kitchen appliances that can process food, vegetables into various desired states by matching different accessories. The more accessories, the more function of the food processors have. Usually, food processors including Plastic Jar Food Processors and Glass Jar Food Processors. According to the function, food processors can be divided into 4 in 1, 7 in 1, 10 in 1 and 15 in 1 food processors. 

Generally speaking, food processors have the following functions: Blender, Juicer, Filter, Grinder, Mixing, Chopping, Citrus, Dough making, Egg whisk, Slice, Shred, Mash, Frech fries making, etc.
