Line Array Speaker System

Line Array Speaker Rental

We recommend you should take a setup with line array speaker rental.
Line array speakers aren’t one single tap unit, but rather are made up of loudspeaker cabinets.
Sound can be focused on the audience and won’t reflect on surfaces.
Sound keeps its level consistent as it travels. That way, the audience members at the back of the venue are served equally as those at the front.
The longer the array, the more tightly directional within the vertical dimension sound will be.
Well-paired individual cabinets into the array might need to all be small vertically in order for the beam of sound to be more controllable from the array

Line Arrays

While column loudspeakers performed well back in the day, they didn’t have adequate scale or science. levels drop by 6 decibels for each doubling of distance. But the level does not drop at all with the plane source. However, the line source drops by 3 decibels for each doubling of distance, which theoretically can generate a cylindrical wave instead of a spherical wave of the point source. True cylindrical waves would have 360° dispersion in the horizontal dimension, and no dispersion in the vertical dimension.

In order to achieve focus, a sound source must be in the vicinity of around four times the wavelength. Wavelengths of audible sound reach 17 meters (20Hz) and more. However, a lower frequency of 170Hz with a wavelength of two meters will require line sources to be eight meters high.

To make loudspeakers many meters high, stacking many loudspeakers on top of each other is often necessary. However, rather than stacking 10–inch loudspeakers with poor HF response, every loudspeaker features LF and HF drive units that cover the entire audio range. In addition, instead of making a very tall cabinet, modern line arrays feature many smaller cabinets. The advantage here is that a line array can be assembled as large or small as you desire. The shape of the array can also be modified.

Line arrays aren't one single tap unit, but rather are made up of loudspeaker cabinets. Individual units will need to be paired together, but only when the drive units are separated by under half a wavelength. While simple for lower frequencies, it’s more challenging as wavelengths shorten. As a general rule of thumb, 400Hz wavelengths are approximately 85cm.

Make It Easy

Sound Should Always Be Directed Towards the Audience

An important rule when it comes to PA systems is to ensure that the sound is always directed towards the audience, and nowhere else. But this often doesn’t happen for whatever reason.

The most important rule in the world of loudspeakers is to point them directly at the audience. It’s also important to think about how much sound is being ricocheted off the walls and ceiling. The audience members will absorb just about all the sound that is directed at them; sound won’t necessarily bounce off them towards other parts of the venue. But walls and ceilings are much more reflective in nature; therefore, the more sound is directed at them, the more sound will bounce off them and distort sound.

EAW CLA37 column loudspeakers use seven 3–inch drive units to cover 120° horizontal x 30° vertical, thereby helping to tightly control the vertical dispersion. It’s perfect for speech reinforcement in spacious environments if many units are distributed to the audience.

When speech content is of main importance, the best solution would be to make use of a variety of small loudspeakers and keep them close to the audience members. However, this option isn’t adequate for a musical performance because we expect the sound to come from the stage, which is typically where the performers are. If the sound came from a small speaker sitting at a short distance away up and to the side, it would conflict with the visual and the audio.

Since having many small speakers doesn't work for musical performances, it’s necessary for the sound to seem as though it is coming from the stage as much as possible. For this reason, it’s best to have the loudspeakers positioned at the sides of the stage. Yet there are still possible issues with this.

For starters, directivity can be a problem. Loudspeakers naturally have a directional response, so anyone that’s sitting right in front of the loudspeaker will hear a rather flat frequency response. On the other hand, those who are sitting further to the side will hear less high frequencies, making the sound seem very dull. Big stereo systems will suffer because they spray the walls and ceiling with low frequencies that reflect too much, and only a few people in the audience will be able to hear sound with well-balanced frequencies.

Another issue is the lack of directional control. Since most of the sound is spread out a great deal past the audience, energy is lost. Sound sources get quieter as they become more distant because of the energy that is spread out. Distance can ruin everything; members of the audience that are sitting far away from the loudspeakers will hear a distant and quiet sound, while a person close to the speakers are experiencing sound that is far too loud.

Setting Up Line Arrays

PA systems need to be assembled at stage level, with the entire system hoisted up. Luckily this can be done without having to touch it through the use of remote controls. Line arrays can be set up by only a couple of people, in fact. However, when any component needs to be airborne at any point, much more responsibility is warranted. The most dangerous part messig up the system is when the equipment is at stage level.

When setting up a PA system, you need to make sure that you position it right. The height and horizontal angling needs to be right, and the array should take up a J–shaped curve in order for sound to be distributed evenly from the front to the back. Software can simplify this process, which can be used to calculate all parameters.
