The difference between the U segment and the V segment wireless microphone and the better analysis of the U segment than the V segment

In the context of sound reinforcement for live performances or entertainment, choosing between UHF (U segment) and VHF (V segment) wireless microphones is crucial. Typically, VHF microphones are commonly used in environments like hotels, convention centers, and educational systems, while UHF microphones are preferred for broadcasting, television, and theatrical productions. When multiple channels are required to operate simultaneously, true diversity reception is often employed to enhance signal stability. However, experienced technicians usually conduct on-site tests before an event to ensure that the electromagnetic environment is suitable for the chosen wireless microphone system. Understanding the differences between UHF and VHF wireless microphones is essential for making an informed decision. While both have their own strengths, UHF is generally considered more advanced and reliable for professional use. The main distinction lies in how they transmit and receive signals, their interference resistance, and their overall performance in different environments. One key difference is the way the transmitter operates. VHF transmitters typically use frequency multiplication circuits to generate high-frequency signals, with a fixed carrier frequency. In contrast, UHF transmitters often employ phase-locked loop (PLL) technology, allowing for adjustable frequencies. This flexibility makes UHF more adaptable in complex environments. On the receiving end, VHF receivers are usually set to fixed frequencies, whereas UHF receivers can be tuned to different frequencies, offering greater control over signal quality. Additionally, UHF microphones tend to have better anti-interference capabilities. They can avoid interference by adjusting both the transmitter and receiver frequencies. Many professional UHF systems also feature true diversity, where two antennas are used to receive the same signal, significantly reducing dropouts and ensuring a stable connection. In terms of signal transmission, VHF signals can reflect off small metal objects and pass through non-metallic materials like the human body, resulting in lower feeder loss and longer battery life. However, VHF is more prone to interference from sources such as TV channels, pagers, and industrial equipment. Its usable frequency range is limited (around 61 MHz), making it difficult to manage multiple microphones without overlap. The dynamic range of VHF signals is also narrower compared to UHF. UHF signals, on the other hand, reflect more off metal surfaces and suffer greater attenuation when passing through non-metallic objects. This means that UHF systems require closer placement of the receiver to the microphone and higher transmission power, which reduces battery life. However, UHF has a much wider frequency range (500–900 MHz), allowing for more available channels and fewer conflicts when using multiple microphones. The larger dynamic range of UHF also contributes to better audio quality. The reason many professionals prefer UHF over VHF is largely due to its broader frequency range and superior interference resistance. UHF allows for more channels to coexist without conflict, making it ideal for large-scale events. Additionally, higher frequency bands can carry more data, which is beneficial for high-quality audio transmission. Another factor is the cost and technical complexity involved. UHF components are generally more expensive due to the higher performance requirements, but this also translates into better reliability and less interference. Since UHF is less commonly used in everyday devices, the likelihood of interference is significantly reduced, making it a more stable choice for critical applications. In conclusion, while both UHF and VHF wireless microphones have their own advantages, UHF tends to be the preferred choice for professional settings due to its superior performance, greater flexibility, and reduced interference. Choosing the right frequency band ultimately depends on the specific needs of the application, the environment, and the desired level of audio quality.
