When it comes to audio rigging for all the sound engineers and event-organizers out there, a line array PA system delivers quite an impressive set of benefits. Line array PA system design provides uniform coverage to a wide area, so it is suitable for large venues in which audience has more than 1000. It is designed with multiple speaker cabinets in a vertical arrangement, which ensures much more balanced sound distribution and less influence from the reflection or interference of sounds.
The line array PA systems feature high quality speaker that offers perfect well as distortion less sound. With the aid of advanced technology, including waveguides and phase-correction techniques for a clear and accurate sound reproduction. As a hint, an optimally-operated line array PA system has the potential to output sound pressure level (SPL) of around 140 dB @1m which is just enough for covering large concert halls and outdoor playing.
A line array PA system are capable of controlling the dispersion. However, sound emanating in different directions hardly affects zones approximately 30 cm away due to electro-acoustic principle by altering the angles of individual speaker modules so as to reduce spillover. This directional control reduces feedback and increases sound reinforcement efficiency. In industry terms, a line array has a uniform sound coverage pattern shaped like 120 degrees horizontal and maybe as much as 20-degrees vertical.
There is also the scalability of line array PA systems. The performance of these systems can be extended to larger venues or higher output requirements by adding more speaker modules. For example, a typical line array system may have 8-16 speaker modules per side, but can be expanded for larger events or reduced to smaller size systems according to the specific application. The modular system therefore provides the flexibility and adaptability needed to be implemented in different settings.
The line array PA system also enhances the visual beauty of an event. Stands now less obtrusively thanks to their slim and vertical design compared with traditional speaker setups. This is especially crucial for a large data show or other high-visibility applicationigs in which the appearance of sensitive visuals are paramount.
One of the most prominent areas line array PA systems have proven themselves in is large musical festivals and live concerts. The prestigious Glastonbury Festival is a prime example where line array PA systems are deployed to deliver high-fidelity and low-distortion sound reinforcement for crowds exceeding 200,000 people. This performance characteristic illustrates the strength and reliability of line array systems, as they can deliver clear sound over such great distances.
