Advantages and Disadvantages of Having an Infrared Microphone System

Wireless infrared microphone systems are ideal for public speakers, musicians, actors, and other performers. Most wireless infrared microphones allow for hands-free operation and the ability to move freely about the stage or platform. 

Sound quality is comparable to hard wired models and certain models can be used in environments where radio frequency (RF) signals may not be allowed. Performance is enhanced as there is no need to worry about tangled cords or cables.

The infrared wireless system has a transmitter and a receiver. The transmitter connects to the microphone via a cable and the receiver connects to the sound system with a cable. The two units communicate using invisible light waves generated by the transmitter, which are picked up by the receiver. The unit requires an unobstructed line of sight for proper operation. Here are a few advantages and disadvantages of having an infrared microphone:


A major advantage of an infrared microphone is its ability to communicate wirelessly. This allows the use of these microphones when cabling is unavailable or impractical.

Infrared microphones are covert devices because they use infrared light to transmit sound. Infrared light is invisible to the naked eye, as it is at a higher frequency than visible light on the electromagnetic spectrum; therefore an infrared microphone system is hard to detect by visual inspection alone.


A major drawback of the infrared wireless microphone system is that these devices can only work within a limited range of about 30 feet. They do not work well in multi-room settings or large hall rooms.
