How to choose the professional stage audio?

Input Time:[2016-1-30] Read:[102]次

Acoustics, rather, is the integrity of the manufacturers of the stereo set machine, its function as complete as possible, easy to use, look gorgeous. All part of the combined sound, such as speakers, amplifiers, booth and CD are provided by the manufacturer, is to cooperate on the whole, and are more uniform in shape, beautiful; After buying customers don't need to spend a lot of time debugging, generally can be used directly, more convenient in operation, function is relatively complete.

First is to adhere to the principle of practical, strictly speaking, each made up of the quality of products is useful products, but the practical product is not equal to what occasion is practical, it must be in certain circumstances, cooperate with some other equipment can be called a practical, otherwise can only is a waste, idle. For example: design will not, after the confirmation of the acoustic pressure and acoustic power of the power amplifiers and speakers should also on this basis, refer to different USES appropriate to add some. If we do not consider the calculation results, according to high power models to choose, this is not practical.

Second is to adhere to the principle of suitable, also want to say which one specific equipment if applicable, are not quite sure, can only say that the choice of a device is not suitable for a particular occasion applicability depends primarily on two usages and characteristics of engineering, as long as it is compared with the engineering use selection. Are likely to cause shall not apply to the results, and practical is not quite same, selection of practicality is not high, the device may also occasionally need; Applicability is bad, if equipment is basically a waste. For example: for a recreation hall equipped with dedicated to recording use of 8 track recorder, seems is not applicable. For a small set of large stage with a child of the sky that forced light or 1000 w, 500 w lamp, also do not apply. To avoid mistakes, not apply not only to design personnel have comprehensive knowledge of the characteristics of most equipment, and need full to users in the selection of engineering design were introduced equipment performance.

Furthermore is to maintain the consistency of the device class performance, specifically: in a series of audio lighting equipment in coke, basically should make their style is consistent, price, performance and unified, or match ". Because many products have some famous has good collocation of related equipment, and the tie-in way have stood the test of many professionals, so it is not difficult to do "match point" is the designer must have the rich experience, otherwise only by feeling to matching, thus inevitably there is not unified.

Since the use of professional audio place and purpose, so we can preliminary judgment most desktop audio is broadcast radio, pop music, such as voice content, so for the stereo speakers don't require work frequency is too low. Usually sound system the performance of the lowest frequency can be selected in more than 40 hz, of course this is only one unit for each speaker.

If each speaker can ensure that the two units (high and low sounds are coaxial speakers halved together of speakers), the sound effects will improve a lot. As a band like a musical instrument of expressive force is stronger.
