The number of channels indicates how many different frequencies, i.e. communication paths, are available to the wireless system. Each channel represents one specific frequency on which the microphone, i.e. the transmitter, communicates with its base, i.e. the receiver. In order for two wireless systems not to interfere with each other, each must operate on a different channel. If they were to run on the same one, interference would occur, which would manifest itself as unwanted sound, noise or complete loss of signal. Systems with fewer channels, such as up to sixteen, are suitable for simpler applications where only a few wireless devices are operating simultaneously. Conversely, systems with a large number of channels, which can reach into the thousands, are designed for professional deployments at large events such as concerts or conferences. Here, many wireless microphones and eavesdroppers are in use. The high number of channels gives the user the confidence that they will always find a free and clear frequency without interference from other equipment or local TV broadcasts. A higher channel count therefore means greater flexibility and reliability in challenging environments with high concentrations of wireless signals.
