Choosing wireless microphones for a church is one of the crucial decisions to make. Wireless microphones are essential for worship, preaching, musical performances, and various events, and selecting the right wireless microphone plays a vital role in determining the audio quality, reliability, and convenience. This blog will cover the key factors to consider and some recommendations when choosing wireless microphones for a church.

Types of Microphones

Handheld Microphone: Common Type: The handheld microphone is one of the most commonly used microphone types, characterized by being held in the hand. It is primarily used for speech or vocal recording but can also capture various sounds, including musical instruments.

Lavalier Microphone: The lavalier microphone features a small and discreet design, typically clipped to a necklace or clothing for hands-free operation. It is commonly used for voice recording, offering convenience for speakers, actors, etc., as it can be discreetly clipped and positioned close to the mouth. However, it's not recommended for situations where the user's mouth is not in close proximity.

It is commonly used for voice recording, particularly convenient for speakers or actors recording their voice. Its clip allows for inconspicuous installation.

Headset Microphone: This is worn over the head and is suitable for environments with a lot of movement and performance. Positioned near the user's mouth, it provides high-quality voice recording.

It is used when musicians need to move freely while playing their instruments. Various types of microphones are available to suit different instruments, and they can be fixed to the instrument, allowing for consistent sound capture at a certain distance.

Types of Microphones

A wireless microphone is a device that transmits audio signals using radio waves, and depending on the frequency used, some may require licenses while others can be used without. The frequency band requiring a license is between 470 and 698 MHz, and to use wireless microphones in this frequency band, you need to obtain permission. The frequency band that can be used without a license is between 925 and 937.5 MHz, allowing you to purchase and use wireless microphones in this range without additional authorization.

Even when used in different spaces, wireless microphones may experience interference if the distance is not significant. If using 20 channels or fewer within the same building, it's advisable to choose the 900 MHz band (unlicensed frequency range). If the number of channels exceeds 20, it's recommended to utilize additional channels within the licensed frequency band.

Wireless Microphone Antenna

Antennas come in various types depending on their directionality, signal amplification, and available frequency range. When selecting antennas, it's crucial to verify the available frequency range.

Depending on the installation location and distance, wireless signal attenuation may occur. To minimize such signal loss, you can utilize boosters. Boosters amplify the wireless signal to extend its reach. It's generally recommended to use a maximum of two boosters, offering either +6dB or +12dB amplification options.

Antenna boosters should be used based on calculations of signal loss due to cable type and length. Excessive signal amplification can induce signal loss, so careful adjustment is necessary.

Using wireless microphone management software allows convenient control of the wireless microphone status and settings. It is mostly applicable to high-end products equipped with a LAN port.

Wireless Microphone Battery Charger

Using disposable AA batteries in wireless microphones is not recommended for safety and environmental reasons. Instead, it is advisable to use dedicated rechargeable batteries and their respective charger.

Integration of Digital Audio Mixer and Wireless Microphones

Using wireless microphones and digital audio mixers that support DANTE allows for convenient multi-channel monitoring as the mixer displays key wireless information such as mute status, signal level, and battery bar viewing in a glance.

Selecting the preamp tab on wireless channels displays more detailed information including RF frequency, device name, and peak indicators. Receiver gain and mute can also be directly controlled from the console or console software.

Wireless Microphone Manufacturers

When choosing a wireless microphone, it's important to select products from reliable manufacturers. Popular wireless microphone brands include Shure and Sennheiser. These brands offer high-quality wireless microphones and provide a variety of options with different types and models. The difference between the products of these two brands is minimal.
