Wireless Microphone Solutions: Equidistant Frequency Spacing


This article explains the term "Equidistant Frequency Spacing", an important procedure used wireless microphone systems

Wireless microphones are devices that capture audio and transmit it wirelessly, offering greater mobility than microphones that use a physical cable connection. They are extensively used in diverse fields such as event venues, conference facilities and educational institutions. Wireless microphones function by converting the sound waves into an electronic signal. This signal gets transmitted over radio waves to a receiver unit, which then converts the signal back into an audio output.

What are the benefits of Equidistant Frequency Spacing?

Intermodulation-free wireless microphone systems allow for equidistant frequency spacing. As the name implies, frequencies are arranged at equal intervals in this procedure. This allows transmitters to be positioned evenly across the spectrum resulting in more channels of wireless audio within a limited available spectrum. Equidistant frequency spacing thus allows for high spectral efficiency of the RF service.

Sennheiser’s Business Solutions offers several wireless solutions that take advantage of equidistant frequency spacing to deliver high-quality, reliable audio performance. For example, EW-DX is a scalable digital wireless system that provides a robust solution for UHF congested settings that uses equidistant frequency spacing to maximize channel density.
