Rent line array systems

What a line array is and what you use it for

A line array is a vertical column of identical loudspeaker elements that are linked together and work as a single acoustic source. Instead of each element radiating in its own direction, together they form a narrow, directed beam of sound. That beam is wide enough horizontally to cover the entire room, but tight vertically, so you can aim the sound precisely over the heads of the audience rather than wasting it on the ceiling or the floor.

The great advantage of this is consistency. With standalone speakers the volume drops off sharply the further away you stand: those at the front get too much, those at the back too little. A line array loses far less energy over distance, keeping the difference between the first and last row small. For large or deep rooms, that is exactly the problem you want to solve. A line array is therefore the heaviest category within our sound range, and the logical choice as soon as an ordinary stereo setup falls short.

How the beamforming works

Because the elements hang close together in a gently curved line, their sound waves reinforce one another in the desired direction and partly cancel out where you do not want sound. By varying the angle between the elements, you bend the beam so that it reaches the far rows at the top of the room and the nearby audience at the bottom. Shaping the coverage in this way, in practice building the curve, is the heart of working with a line array and determines whether the system lives up to its promise.

When to use a line array

A line array comes into its own as soon as the audience grows large or the room has an awkward shape. A few concrete situations make this clear.

At a presentation or conference in a large venue, intelligibility is everything. Hundreds of visitors all need to hear the same clear speech, whether they are on the second row or the last. A line array distributes that voice evenly across the depth of the room, without becoming uncomfortably loud at the front. In a long conference hall that is often impossible with standalone speakers.

At a large corporate event with a mixed programme of speakers, music and a closing party, a line array delivers the flexibility and the power to handle it all. Clear enough for keynotes during the day, powerful enough to get the room moving in the evening, all with the same system and without switching gear.

At a large company party in a spacious venue or hall, it is all about full, carrying sound that reaches everywhere. Combined with subwoofers, a line array provides the foundation and the volume for a dance floor that keeps going all night, while the coverage stays even so there are no noisy hot spots.

And at a large wedding with plenty of guests and an evening party, a line array ensures the speeches can be followed clearly everywhere and that the celebration can really let loose later in the evening. From a whisper-soft ceremony to an exuberant dance floor: the system has the dynamic range to cope.

The technology: setup, tuning and operation

Rigging and setup

A line array works best when it is flown. Suspended from a truss or a rigging point above the stage, the elements sit at a height where the beam can carry over the audience into the room. Flying is done with certified rigging and calls for a sound suspension point, which we assess in advance together with the venue, so the setup is safe and fully compliant. Where flying is not possible, we work with a ground stack on subwoofers or a lift stand, although the coverage is then slightly more limited.

When setting up, we determine the height, the number of elements and the angles between them based on the room. We often supplement a line array with separate front fills for the very first rows, which fall just below the beam of the main system, and with subwoofers for the low-end foundation. This gives you seamless coverage from front to back.

Tuning and testing

Once the system is hung, tuning follows, and with a line array in particular this is a craft. We set the levels per zone, use the equaliser to correct the characteristics of the room, and make sure the transition between the main system, the front fills and the subs is seamless. We pay close attention to the timing between the different parts, so everything arrives as a single sound with no echo or delay. After that we run a test with the actual sources, so you can hear in advance how speech and music will sound in the room.

Setup and timing

A line array takes more setup time than a set of standalone speakers. Flying, aligning and tuning it all takes time, which we schedule well before the start so there is room to test calmly before the first guest arrives. Cables are neatly routed and taped down, and the rigging is checked. The exact setup time depends on the size of the system and what the venue allows.

Operation on site

For a line array production a technician stays on site. A large room sounds very different empty than full, and a programme that switches from speech to music calls for adjustment. The technician monitors the levels, keeps an eye on the balance across the entire depth of the room and corrects where needed. That way you get the very best from the system and the sound is right from the first word to the last track.

Points to consider specific to line array systems

A line array is powerful, but that very power means there are things that need extra attention. The suspension is the most important: without a suitable, certified rigging point you cannot fly safely, and that often determines what is possible at a venue. We always assess this in advance, so you are not caught out by surprises on the day.

Also keep an eye on the vertical aim of the beam. A line array that is bent down too little shoots over the audience and bounces off the back wall; too far down and the far rows get too little. Setting that curve accurately is exactly what you rent a line array for, and it is the reason tuning by an experienced technician matters so much.

Think, too, about power and load. A large system with amplifiers and subwoofers draws a lot of current, so we check the available circuits at the venue in advance. And bear the acoustics in mind: a reverberant room with plenty of glass and concrete calls for careful tuning, because a line array reveals both the strengths and the flaws of a space clearly. A line array is therefore not a plug-and-play solution, but a system that only shines with the right preparation.

Combining with lighting, video and effects

A line array rarely stands on its own. At large events it works alongside the other disciplines, which makes coordination all the more important. If you are working with speakers and imagery, the sound from a film or presentation must connect seamlessly to the same system, with no difference in volume or delay. Our video range links up directly with this, and in a large venue the audio from the imagery simply runs through the same line array.

Lighting and sound reinforce one another as well. At a big party the line array and the lighting build the tension together towards the climax of the evening, and at a conference lighting supports the focus on the speaker while the system carries the voice. If you are working with special effects, such as confetti or low fog at a climax, the impact lands most strongly when the sound comes through full and even across the whole room at exactly that moment. A line array often hangs from the same truss as the lighting, too, so we coordinate the setup as a whole.

Practical tips

Share the floor plan, the dimensions and the number of guests as early as possible, because that lets us genuinely calculate the coverage and work out how many elements you need. Ask the venue in advance about the rigging options and the available power; that saves hassle on the day. Think about the most demanding moment of your programme and size the system for that, not for the average. And set aside enough time for the setup and a real test with your own speech and music, because with a line array that preparation pays off directly in the room.

If you want to collect and set up a compact set yourself for a smaller event, you can rent standalone speakers directly online via SpeakerVerhuur.nl. We supply a line array as part of a complete production, because rigging, tuning and operation are essential to a good result. HuurAV is part of Speaker Verhuur Amsterdam and handles the full technical side on site.
