Now, on to the top 10 considerations for selecting a sound system or public address system (PA) for your church:

Start with Coverage:

First, let’s start with a bonus:

Endlessly debated in the church world is the difference, preference, and advantages of a Line Source system compared to a Point Source system. The simple answer is, no solution is perfect for every situation. However, depending on measurable, arguable metrics such as coverage, performance over the frequency spectrum, and budget, a clear advantage will emerge.

When considering a new sound system for a church, one crucial decision to make is whether to opt for a point source system or a line array system. Each system has its own advantages and considerations that need to be evaluated based on the specific needs and characteristics of the church. Let’s explore the key factors when comparing point source and line array systems:

Sound Dispersion and Coverage:

Point Source System:

A point source system typically consists of a single loudspeaker enclosure that radiates sound in all directions. This configuration provides even sound dispersion and coverage across the entire audience area. Point source systems work well in smaller churches or venues where the audience is relatively close to the speakers.

Line Array System:

A line array system comprises multiple loudspeaker elements vertically stacked or flown together. Line arrays offer more precise control over sound dispersion, allowing for better coverage over long distances and in larger venues. They can project sound evenly and reach a wider audience area, making them suitable for churches with larger seating capacities or challenging acoustic environments.

Vertical Sound Control:

Point Source System:

Point source systems typically provide limited vertical control over sound dispersion. Sound spreads both horizontally and vertically, which can lead to potential challenges in venues with high ceilings or balcony areas. Proper positioning of point source speakers is crucial to mitigate these issues.

Line Array System:

Line array systems offer superior vertical sound control. By adjusting the angles and aiming of individual loudspeaker elements within the array, the coverage can be tailored to match the vertical distribution of the audience. This capability allows for more precise targeting of sound and better control over potential reflections and reverberations in complex venues.

Intelligibility and Clarity:

Point Source System:

Point source systems can deliver excellent sound quality and intelligibility, especially in smaller venues. With the right speaker placement and acoustic considerations, they can provide clear and articulate speech reproduction, making them suitable for churches that prioritize sermon intelligibility over long distances.

Line Array System:

Line array systems excel in providing consistent intelligibility and clarity over a larger audience area. Their precise sound control minimizes echoes, reflections, and variations in sound levels, resulting in improved speech intelligibility and enhanced musical performances. Line arrays are ideal for churches with larger seating capacities or venues where consistent sound quality is critical.

Architectural Considerations:

Point Source System:

Point source systems are generally more discreet and visually less obtrusive compared to line array systems. They are easier to integrate into the architecture of the church without compromising the aesthetics. This makes them suitable for churches where preserving the visual ambiance of the space is a priority.

Line Array System:

Line array systems, due to their multiple loudspeaker elements, can be more visually prominent. They may require flying or suspending the loudspeaker arrays, which can impact the aesthetic appeal of the church interior. However, advancements in line array design have made it possible to achieve more visually appealing and compact line array configurations that can blend seamlessly with the architectural elements.

Budget and Scalability:

Point Source System:

Point source systems are generally more cost-effective and simpler to implement compared to line array systems. They require fewer components and can be a more budget-friendly option for smaller churches with limited resources. They are also easier to scale up or down, making them adaptable for future growth or changes in the church’s needs.

Line Array System:

Line array systems often come at a higher cost due to the multiple loudspeaker elements and the associated hardware required for their installation. However, line arrays offer scalability and the ability to accommodate larger venues or growing congregations more effectively. They provide greater flexibility for future expansion or changes in the church’s audio requirements.

Choosing between a point source system and a line array system depends on several factors, including the size of the church, seating capacity, acoustic characteristics, budget, and aesthetic considerations.

1 – System Goals and Requirements:

Clearly defining the goals and requirements for the sound system is fundamental. Consider factors such as the size of the congregation, types of services and events held, musical performances, and any future expansion plans. These aspects will help shape the system design and equipment choices to meet the specific needs of the church. For example, a larger church with a strong musical emphasis might require a system capable of delivering high-quality music reproduction, while a smaller church may prioritize speech intelligibility. Additionally, when comparing point source systems and line array systems, factors such as sound dispersion and coverage, vertical sound control, intelligibility and clarity, architectural considerations, and budget and scalability should be taken into account. Choosing the right system depends on the specific characteristics of the church and its desired audio outcomes.

2 – Budget and Long-Term Cost:

Establishing a realistic budget is crucial for a successful sound system installation. For a small system, 100-200 congregants, a quality sound system may exceed $20,000 USD (2023). For larger facilities, the cost can balloon to well over $1 Million USD (2023) for a concert class PA. When attacking the budget conversation, consider not only the initial costs but also the long-term expenses for maintenance, upgrades, and training. It is critical to remember that you will never out suck your PA. If you install a bad stereo, you will never achieve quality beyond what your sound system can produce. This is an essential trade off to understand when selecting a PA. If you select cheap, then you will receive cheap results.

While it may be tempting to allocate a significant portion of the budget to the sound system itself, remember, there are other elements of the system that must be considered:

  • Room Treatment
  • Audio Mixer
  • Band Microphones, Inputs and Drums
  • Wireless Microphones and Monitor systems
