【 Weak current College 】 e-mail divider roles and features

(A), roles and features

1. basic frequency tasks: because now there are many kinds of sound, what you want to use the system functionality, some spectrum of electronic dividers or flexible configuration, the nowadays usually use of e-modulus 2 crossover, 4 3 frequency, frequency, etc., more than 4 frequency becomes too complicated and no practical significance. Of course, now the electroacoustic technology advances, there are still some divider in the frequency of the audio signal can also be some other aspects of treatment, but no matter what type of e-modulus prescaler of key features and tasks of course or frequency.

2. protection of sound equipment: we know the different speakers working frequency is not the same, in General, the larger the diameter of the speaker, the better low-frequency characteristics are, the lower the frequency dive also. As if in the same circumstances, 18-inch speaker bass General than the 15-inch bass and some of the speakers; on the contrary a tenor part is small-caliber speakers, because normally it's cone of vibrating speaker diameter smaller sound frequency is higher; and so on treble section of vibrating diaphragm should also give a very small to very high frequency sounds. Since the speaker so complicated, kind and so many, so how do you protect them to safe and effective work becomes very important. E-modulus prescaler can provide different speakers are their needs best operating frequency, so that various speakers are smarter and more secure work. Imagine: If the system in the treble speakers without electronic frequency divider ratio, but directly using a full range of audio signal, then these treble speaker on the impact of the low-frequency signal is easily damaged, therefore, in addition to electronic divider dividing tasks, the normal use of its more important features include: protection of the sound device.

3. increase the level of sound: If a sound system, there are many different types of speakers only, do not use electronic dividers, different types of speakers are used without the full-frequency signal frequency, between the different speakers there will be many frequency overlays, repeating section, acoustic interference becomes very serious, the sound will become blurred, sound field also is very poor and microphone also prone to acoustic feedback. If you use electronic dividers are reasonable frequency for different speakers in top working condition, such as between the different speakers sound frequency range almost never repeated, this reduces the acoustic phenomenon of mutual interference, voice will become more clear, the tone will be better and more layered!

(Ii), shortcomings and weaknesses

1, too many frequency selection will cause the ideological confusion: as the saying goes, enabling it has its advantages and disadvantages, and other professional audio peripheral equipment, electronic frequency divider is not perfect, there are times when the system needs a lot of sound frequency will appear very complex because different speakers would need a different frequency point, a different frequency, for horizontal General Audio Division, in such cases the use of electronic frequency divider ratio will let them know that start. Therefore a careful careful adjustment is very important, we also can use 4-n, 2 3 crossover or frequency of method, which can be as simple as some would make our adjustment becomes more clear.

2. After using the e-modulus prescaler can cause sound reduction: Although the use of electronic divider has many advantages, but because of its rigid provides different speakers working frequency range, thus also makes these speakers of effectiveness was limited, not fully realized, wasted a large portion of the resource. For example: a pair of 15-inch full-frequency sound without electronic dividers can be issued very normal and larger voices, but if you go through the e-modulus prescaler crossover frequency above after 200Hz work, then the only speaker of fullness and shocking is all gone, because the sound of the bass to the e-modulus prescaler cut off. The same situation we use electronic dividers also cut off most of the treble section sub-woofer, although this timbre may sound good, but it is undeniable that bass speaker also wasted a lot of energy. This number for speaker and kotsuzumi audio system also does not matter, but if a sound system of the small number in the box without paying attention to timbre just louder, that you still don't use electronic dividers reality.

3. assigned frequency unreasonable can cause damage to the equipment: the above said the rational use of e-modulus prescaler can protect equipment, electronic frequency divider or a double-edged sword, used incorrectly, it will damage the equipment: for example we take in from electronic divider separating the treble signal to the subwoofer speaker, due to the bass Horn not so high frequency sounds, so that the phenomenon is: treble speakers and subwoofer speakers will have a voice. If some sound reasons, not seen merely increase after the former level signal and power amplifier's volume level, then the result is increased and a large volume. You also can easily damage the amplifier, and if level signal to distortion is also easy to burn out the speaker, don't think that bass speaker no sound no matter, after all, you already have a lot of current in the coil through the Bass trumpet. Other speakers are by the same token, the improper use of e-modulus prescaler is to damage the device, in the following pages will have a examples for your reference.
