A line array is a speaker system designed to project sound in a controlled manner over long distances. Unlike conventional speakers, which radiate sound in all directions, line array speakers are arranged in a vertical line, allowing for:
- Controlled sound dispersion: Concentrating energy towards the audience and minimizing unwanted reflections.
- Consistent SPL (Sound Pressure Level): As the sound travels, the level decreases more gradually compared to traditional systems.
- Customizable coverage: Adjusting the angle and arrangement of the modules to match the space’s characteristics.
How Do Line Arrays Optimize Sound Coverage?
Constructive Interaction
Line array modules work together to create a coherent sound wave. This increases system directivity, ensuring that sound reaches even the farthest areas with clarity.
Frequency Control
Line array systems are designed to maintain uniform coverage across the entire frequency range. Low frequencies often require additional support, such as subwoofers, to ensure even distribution.
Reduced Sound Loss
In traditional systems, sound levels decrease by 6 dB with each doubling of distance. In a line array, this loss can be reduced to 3 dB, resulting in much more efficient coverage.
Advantages of Line Array Systems in Live Events
✅ Uniformity: The entire audience, regardless of location, experiences a similar sound pressure level.
✅ Versatility: They can be adjusted to cover anything from small theaters to open stadiums.
✅ Reduced environmental noise: By concentrating sound towards the audience, dispersion into unwanted areas is minimized.
Featured Tecnare Line Array Models
Cla208: Compact and Versatile
🔹 Key Features:
- Designed for sound reinforcement in medium-sized venues.
- Offers excellent vocal clarity and controlled dispersion.
- Ideal for theaters, churches, and conference halls.
📌 Practical Example: In a corporate event held in a medium-sized hall, the Cla208 can be configured in linear arrays to ensure clear coverage without requiring high sound pressure levels. Its compact size makes it perfect for installations where space is limited.
Cla21Plus: Power for Large Events
🔹 Key Features:
- Modular line array system suitable for medium to large-scale applications.
- Optimized for outdoor events and concerts.
- Compatible with subwoofers such as the SW218V, providing additional low-frequency support.
📌 Practical Example: In an outdoor music festival, the Cla21Plus can be installed in configurations of up to 12 modules per side, ensuring that sound reaches every corner of the venue. Its modular design allows for angle adjustments to prevent over-coverage or dead zones.
Cla312: Power and Clarity for Large Venues
🔹 Key Features:
- Designed for large-format applications such as stadiums and large auditoriums.
- Delivers excellent low-frequency response without requiring additional subwoofers.
- Robust construction optimized for high sound pressure levels.
📌 Practical Example: In a stadium concert, the Cla312 is configured in large-scale arrays to ensure uniform sound distribution throughout the venue. Its power and clarity make it ideal for high-profile events.
Tools for Optimizing Line Array Configuration
Proper installation of a line array system requires planning and specialized tools:
Acoustic Prediction Software
Tools like EASE Focus allow users to simulate how sound will behave in the space before installation. This is crucial for adjusting module orientation and angles.
DSP Processors
Tecnare systems include DSP processors that enable precise equalization, delay, and phase adjustments to maximize system coherence.
Real-Time Measurement
During the sound check, spectrum analyzers ensure the system performs as planned, allowing for real-time adjustments if necessary.
Case Study: Concert in an Auditorium
🔎 Preliminary Analysis
Using EASE Focus, determine the best arrangement for a Cla208 system in two columns of four modules each to cover the entire audience.
🎛️ Subwoofer Support
Add SW115 subwoofers to reinforce low frequencies, ensuring a balanced listening experience.
🎚️ Final Adjustments
Fine-tune module angles and delay settings so that distant areas receive the same sound quality as the front rows.
