Sanmenxia where where there sell KTV microphone monopoly wholesale Jiaming Yang 1503 +71780 +75 www.69139139.com 1399 +229 +631 Zheng * City Market Milan sun, Unit 2, Building 208 infrared wireless microphone KTV rooms are now commonly used The device, which is based on the infrared light as a carrier of the voice signal, to achieve launch, the received radio pickup system. The basic principles and is similar to the RF system, and also need to be in a wireless transmitting and receiving process of the sound signal modulation and demodulation process. Infrared light infrared wireless microphone carrier frequency much higher than ordinary wireless systems, the ordinary wireless microphone frequency 200-900MHz, that is commonly referred to as RF (radio stations, television stations, wireless communication chosen band); infrared microphone frequency over 3G frequency environment is clean, there is little the device radiation interference wave. Infrared wireless microphone often following questions. ①, KTV private room is not mirror the more infrared wireless microphone to accept the more favorable? Jiaming Yang 1503 +71780 +75 www.69139139.com 1399 +229 +631 Milan sun, Zheng * City Market Building 5, Unit 2, 208 people often think KTV private room mirror more, infrared microphone accepted effect the more Well, in fact, this is a wrong understanding. Facts have proved that the the KTV room mirror package is more, infrared microphone to accept the worse the effect. The mirror in the light of the reflection process energy loss is very small, but the mirror will light signal is reflected in one direction, objectively hinder the formation of relatively sealed space within dense optical network, leading to the formation of blind spots within the space. Large area mirror interior spaces, can be overcome by increasing the number of receiving head, in order to achieve satisfactory reception.

Due to the the infrared microphone superiority and versatility, any set of microphones can be used in any relative independence * established space, without having to consider the problem of frequency interference; Hatsumi is generic, any pair of A B channel transmitter may work with any one receiving host system consisting of, without considering the emission accepted between corresponding to the frequency, it can greatly reduce the number of provincial alternate microphone, but also reduce result in open room low due to the microphone failure occurs . (3) the infrared microphone will not interfere with each other? The infrared spread in a straight line, and therefore will not interfere with each other in various relative independence * established space between the infrared wireless microphone. But if the same frequency infrared microphone is placed in the same space, it is due to mutual interference can not be used normally. Infrared microphones generally have two separate * established distinction frequency, A, B channels (in the transmitter, there are obvious distinctions) A, B channel signal of a microphone, an infrared receiver host can accept, but A channel can not accept two or more; two or more of the B channel signals.
