Installing a quality church sound system requires comprehensive research for a setup that will last. Taking shortcuts can result in a system with inadequate or incompatible components, affecting the audio quality of services and possibly resulting in extra costs for repairs or replacements. Here’s a guide to get started on the right foot.

Essential Equipment for Any Church Sound System

Microphone

There are two types of microphones used with sound systems: dynamic and condenser microphones. Dynamic microphones are ideal for vocals and other close-distance applications, while condenser mics work best for distant use.

Dynamic mics are durable workhorses. They don’t require a power supply to work, making them affordable options. At the other end of the spectrum are condenser microphones, which cost more. Unlike dynamic mics, they are more sensitive and better at picking up a wider range of sounds. They require phantom power, which comes from the mixer to power up the electronics inside the mic.

Cables & Snakes

The electric signal from mics and other electronic pickup devices travel through the cables. Church sound systems generally use two types: XLR and instrument. A balanced XLR cable has three pins that allow it to connect to the ground, as well as the plus and minus signals to minimize the problems with radios and other types of interference. An unbalanced instrument cable has a 1/4 inch diameter with a single tip, so the ground is also carrying signal. It is important to minimize the lengths of unbalanced 1/4” or RCA stereo cables to reduce the chances of interference.

A snake is a component that keeps the cables together. It’s comprised of several input and output jacks housed in one box. Multiple snakes are often used to manage and run the signals from the source to the mixing board, and then to the amplifiers and speakers.  

Mixers

As its name implies, the mixer combines all audio signals and balances them out to make sure the sounds won’t be too overwhelming to the audience. It comes in three forms: analog, digital, and powered. Analog mixing boards often have multiple dials and sliders to adjust the sound, while digital mixers come with several presets and tweaks, which can be confusing for operators. Powered mixers are a variety of analog types with built-in amplifiers.

Amplifiers & Speakers

Amplifiers boost the signal coming from the microphones and sends it to the speakers. Without them, the sound produced wouldn’t be loud enough for everyone inside the room to hear. Speakers are either passive or powered. To create a loud sound, passive speakers need a stand-alone amplification unit, while powered types have a built-in amplifier.
