If you’re in the market for a new PA system, you may have know the emerging category of consumer line array speakers from brands like JBL, TACT Pro audio.Why is line array speakers ideal for indoor and outdoor large-scale events?Let’s take a look.
Sound analysis
Line array systems have been used for huge tours for decades. The reason is that line array sound system are the best way to get clear sound throughout the venue, from the front row to the very back. This is for a few different reasons.
One aspect of line array sound that makes them so efficient is the shape of the dispersed sound. Point-source (non-line-array) speakers project sound in a spherical shape, radiating out in all directions from the speaker. But your audience usually isn’t surrounding the speaker in all directions — the audience is usually more-or-less in front of the speaker.
A line array system projects sound in a shape that is closer to cylindrical. This greatly reduces the amount of sound energy that is projected vertically (to the ceiling and floor). It’s good to reduce vertical dispersion for two reasons. One is that the extra sound energy bouncing off the ceiling and floor interferes with the direct sound from the speaker and creates a more confused, reverberant sound. The other is that it’s inefficient — projecting sound vertically is a waste of watts. With a line array system, you can use your watts wisely, projecting sound more directly toward ears, rather than all over the room.
Powerful
Projecting sound is more efficiently becomes importantly as your venue size increases, especially if the sound are less-than-great. In a big, reverberant room, if using pa speaker ,you have to turn your pa speakers up more to get clear, intelligible audio to the back of the room. But by doing that you end up exciting the reverberant field in the room more, which causes muddy, indistinct audio that is hard to listen to.
With a cylindrical dispersion pattern, the amount of sound energy decreases with distance at a slower rate. That means that as you move away from the speaker, you lose less volume, meaning that you can project sound farther away using less wattage. This is a huge advantage, allowing more direct sound at lower, less-reverberant-field-exciting volumes, which translates to clearer audio all throughout the room, instead of just at the front, without resorting to side-fill (reinforcement) speakers. And you can do that without destroying the ear drums of everyone in the front row.
But you choose to use different size line array speakers in medium-to-large-sized venues and make the same benefits. With more factory(Such as TACT PRO AUDIO) offering line array models that are getting more sophisticated, and easier to set up without professional installation, in the future maybe more clubs, venues, and hall are going to be using line array sound system technology to achieve clearer, more efficient sound.
