Line array speakers are a powerful kind of loudspeaker system for large audiences. They produce clear, strong sound over a large area. E.V. or Electro-Voice line array speakers are well-known for their smart design and good quality sound.
On the E.V. Line Array Speaker Systems, engineers set the units in a line. This setup makes the sound waves from each unit join together as one big wave at any angle. It allows the speaker to deliver the same clear sound throughout a large space, whether in the front row or back.
There are several types of line array speakers available for various situations and needs. Here are a few of the main types:
These speakers have built-in amplifiers. No external amp is needed. This makes setting them up much easier and faster. They also automatically adjust sound levels for a better experience for people at events.
These speakers need external amplifiers to work. While this takes more time to set up, it allows for greater flexibility in mixing options. Different kinds of amplifiers can be used with these speakers.
These arrays are for low-frequency sounds like bass, meant to hang straight down from ceilings or stages. They are usually much shorter than horizontal arrays, as they take up less space in height than width.
These are for mid-range and high-range frequencies, intended to mount on walls or be set up on the floor/ground. These arrays are typically much wider than they are tall, as their width is important for covering a wide area.
These speakers are specifically designed for voice amplification and for use in smaller venues. They are very compact and portable, making them easy to take from place to place.
These speakers are a special type of horizontal or vertical line array designed just for low bass sounds. They work with the other line array speakers to give the full range of sounds - both high and low.
Unlike the subwoofer line arrays which only amplify low bass sounds, these line arrays can amplify all frequencies of sound from the lowest bass to the highest treble. This allows them to provide complete sound for music and other audio uses.
Choosing the right line array speaker system depends on many factors, including the specific needs of the event or venue, the budget available, and the desired sound quality.
A few key considerations include:
The size of the concert or event will dictate the appropriate speaker system size. Larger events, such as arena or stadium concerts, will require a larger system to adequately cover the space, while smaller events can make use of a more compact system.
The number of drivers in a line array speaker system can also impact its performance. More drivers generally allow a wider range of sound, helping the system deliver both deep bass and high treble. However, more drivers also increase the system's cost and complexity.
The shape and materials of the venue will also impact the sound. For example, a system with stronger bass drivers may be needed for an outdoor space, as the bass tends to fade in open air. Indoor spaces with reflective surfaces may require a system more focused on mid and high frequencies.
What is available within budget will impact the final choice of system. While top-of-the-line systems can deliver exceptional performance, many more affordable options still provide ample sound for smaller events.
How loud the system needs to get will also factor in. If a concert requires quite powerful sound, a more powerful system will likely be needed to deliver the desired decibel levels without distortion.
Different systems have other equalization options. Some provide greater control for tuning the system to the space and the needs of the concert. These controls help shape the sound to better match the requirements for the music or the acoustics of the venue.
Array speakers are designed to provide even coverage over a large area. Ev speakers achieve this through precise vertical and horizontal alignment of the drivers to control the sound dispersion pattern. Full-range Array systems that combine wide horizontal coverage with deep vertical reach can ensure that every listener, no matter where they are seated, experiences the same high-quality sound.
Many array systems are designed to allow for greater flexibility in their placement. This can enable the speakers to be deployed in various orientations or configurations, such as flown above the stage or stacked on the floor, depending on the event space and the needs for coverage. Having greater placement flexibility can be an important factor for production teams who must quickly adapt to different venues and their unique requirements.
Here are some of the key specifications related to an ev line array speaker:
Power output
Powerful line array speakers can put out up to 1500 watts of peak power. This allows them to get very loud without losing sound quality or becoming distorted. Speakers with more powerful outputs are better for larger concert spaces.
Frequency range
Line array speakers can produce nearly all musical ranges in sound, from very low bass notes to high treble. This range typically spans from 20 hertz to 20,000 hertz. Some specialized models can reach even lower or higher ranges.
Maximum SPL
The SPL means sound pressure level. It measures how loud the speaker can get. Many line arrays can reach 135 decibels or higher. This allows them to fill large spaces with clear, powerful sound.
Connectivity
Many line array speakers have other inputs and outputs for connecting to audio equipment. These include options like XLR and 1/4-inch jacks. Some modern models use wireless connections through Wi-Fi or Bluetooth, making setup easier without messy cables.
Speaker drivers
Line arrays use different-sized cones inside the speakers called drivers for short and long sounds. A large subwoofer handles deep, low bass sounds. Smaller tweeters manage higher treble. This combination allows the array to cover all sound frequencies fully.
Driver materials
Manufacturers commonly use lightweight but strong materials like Kevlar, carbon fibre, or aluminum metals for the driver cones. These durable substances ensure the speakers can produce powerful sound levels without damage.
Line arrays are beneficial for many activities. They help sound systems work well indoors and outdoors. Here are some examples:
Musicians can use line arrays at concerts to reach large crowds with clear sound. The speakers ensure that no matter where people are - near the stage or far back - they hear every note perfectly. This is especially important when the music has a wide range of sounds from low to high.
Speakers use line arrays in auditoriums and conference halls so everyone can hear clearly. The even coverage means the speaker's voice is just as loud and clear in every row of seats without 'hot spots' or dead zones. This allows important talks and presentations to be understood fully.
Theatres use line arrays to ensure spoken dialogue and sound effects are heard crisply across large viewing areas. The precise directionality of the speakers allows the sound to project beyond even complex stage arrangements.
Places of worship use line arrays to amplify sermons, choirs, and other performances throughout their large, high-ceiling spaces. The systems enable full, clear sound that envelops everyone attending the service.
Fans at stadiums benefit from line arrays that provide announcements, music, and commentary with even sound, no matter where they are seated. The speakers overcome outdoor challenges like wind and distance.
Line arrays are widely used at corporate functions, including seminars, training sessions, and events with multiple speakers. The technology provides clear, professional-quality sound that supports effective communication in varied-sized venues.
Nightclubs and acoustic music venues rely on line arrays to fully capture dynamic music performances. The systems provide powerful bass and crisp treble so all musical elements are experienced throughout the dancing crowd.
Array speakers are effective for many activities. They work well in both small spaces, like a chapel, and large arenas. The speakers cover the area well so everyone hears clearly at the same volume level. They're good for music and speech events, helping people hear without straining.
The primary role of line array speakers is to give even, clear sound across large spaces. Their tall, narrow shape allows the sound to go straight out and minimize the amount of sound that goes up or down. This keeps the sound level consistent from front to back of the area whether in a small room or a big stadium.
Line array speakers work by placing many small drivers in a column. This focused the sound waves together as they traveled out. The sound stays clear even in large spaces because the waves stay in sync. The drivers overlap each other like a curtain, covering the area with even sound.
PA (public address) speakers and line array speakers differ mainly in their design and purpose. PA speakers are made to amplify voice clearly in small to medium areas, like classrooms or small venues. Line array speakers are meant for larger spaces, like arenas, with their column shape to give even sound coverage far distances. The line arrays are more complex and better for music and larger events because they control the sound wave patterns more precisely than PA speakers.
