Line array systems are a type of sound reinforcement system that are commonly used in live music venues. They are made up of a number of loudspeakers that are arranged in a line, and they work by creating a directional sound field that can be focused towards the audience.
The main advantage of line array systems is that they can produce a very tight, focused sound beam which can be directed towards the audience with great precision. This means that the sound quality is usually much better than traditional PA systems, which often struggle to evenly distribute sound across a large area. Line arrays also have the ability to create very high SPL (sound pressure levels), making them ideal for use in loud environments.
There are some disadvantages to line array systems, however. They can be quite expensive to purchase and set up, and they often require specialist knowledge to get the most out of them. Additionally, because they rely on destructive interference to work effectively, line arrays can sometimes produce strange “comb-filtering” effects if not used correctly.
Overall, line array systems are a great option for live music venues looking to improve their sound quality. While they may be expensive and require specialist knowledge to set up properly, the advantages far outweigh the disadvantages for most applications.
