Do you know the difference between different stereos? The stereo manufacturer tells you
Here the explanation of the field acoustic operation, it and recording technology is a lot of different places, there are a lot of people think that the highest state of sound is recording technology, which is not comprehensive. In recording technology, there is basically no feedback, because when operating in a recording room, all peripheral factors can be controlled, but in the replay of the site audio, we cannot avoid many problems of the site audio, so the site audio and recording audio are two different knowledge.
The requirements of live audio and studio audio are different, so there are many different equipment. For example, the mixer used in the recording room has multiple parameter equalization for each input channel, so that the sound engineer can do the most precise fine-tuning for each input channel to achieve the best sound source effect. A mixer used to make a live sound, usually in each of its input, the equalization is relatively simple. Because most of the time, the field tuners do not have a lot of time to fine-tune the sound source of each channel very carefully, while in the field sound mixer, the volume control push rod of each channel can not only attenuate the volume, but also gain 10-14db. If you are making a sound mixing platform for the recording studio, you don't need to gain the putter in many cases, so the English name of this putter is fader, which means attenuator. For high-power amplifiers used in field acoustics, they all have fans as cooling purposes, because the power amplifiers of field acoustics often work at the maximum power output, and there are many times when doing field acoustics outdoors, the surrounding temperature may be quite high. If be in recording room, usually certain meeting has air conditioning, temperature won't be too high of course, and the power amplifier of recording room, basically be used to push to listen to speaker to use, do not need to output very big power of course, so power amplifier needs to use common radiator only, can scatter very small quantity of heat. If the amplifier is equipped with a fan, the sound produced by the fan will cause noise, so the amplifier in the recording room basically does not need a fan.
Different speakers are used
The stereo speakers, used by to take a lot of pressure spread painting at a distance of the audience, so they are need to be very efficient, but used in the recording room listening to the speaker, is the engineer to be used to monitor the sound source or the end of the recording as a result, the engineer is sitting in the very near from listening to the speaker to listen to, so listening to the speaker is a near sound field of the speaker, don't need high sensitivity, with the stereo speakers is completely different.
