Qt-u700y professional wireless Bodypack transmitter adopts advanced digital phase-locked loop multi-channel frequency synthesis technology. Within 50MHz frequency bandwidth, with 250kHz channel interval, it provides up to 200 channel options, which is convenient for multiple sets of machines to use at the same time, with high frequency stability; multi-level narrow-band high-frequency filtering, fully eliminating interference signals. Traditional wireless microphones can't distinguish noise from human voice signal because they use low frequency noise circuit to analyze the strength of RF signal. When they are used in noisy RF environment (such as CD / VCD / LD mobile phone and other digital devices emitting a large number of harmonic signals), when the transmitter's signal is weak or closed, the noise circuit may suddenly open and the receiver will send out Strong blasting noise. To solve this problem, the company designed this professional class wireless conference microphone. Multistage narrow-band high-frequency filtering adopts the noise digital suppression circuit of high-frequency transmission and reception, which analyzes the quality of the signal rather than the strength of the signal. When the transmission signal is strong, the noise sound level of the system is low, and the receiver lets the sound pass through. When the transmission signal is weak or there is no signal, the noise sound level high suppression circuit of the system will make the receiver muffle, which has eliminated the annoyingness The possibility of blasting noise through your receiver. Easy to avoid all kinds of interference, advanced automatic frequency matching technology even if the frequency of transmitter and receiver is disordered, you only need to press it lightly, the transmitter will automatically track the receiver frequency and adjust the same, easy to use.
