Product Description:
J Series Wireless Conference Microphone with quartz oscillator circuit has a very high frequency stability; multi-level narrow-band high-frequency filter, fully eliminate the interference signal. Traditional wireless microphone for use with low frequency noise suppression circuit, by analyzing the RF signal strength, noise and they can not distinguish the desired signal; in a noisy RF environment (such as CD / VCD / LD and other digital devices emit a large number of harmonics) used in the transmitter signal is weak or closed, may suddenly open the squelch circuit, the receiver will send a strong burst noise. To solve this problem, the company has designed this professional grade wireless conference microphone. Multi-level narrowband frequency filtering, first a high-frequency transmitting and receiving digital noise reduction circuit, which analyzes the signal quality rather than signal strength, signal strength when the transmitter, the sound system's noise levels low, so the sound receiver by a transmitter signal is weak or no signal, the system's noise level is high, the receiver will suppress circuit muffler, which has ruled out the annoying noise of blasting through your receiver possibilities.
