The U-3550 is a dual channel, non-diversity, PLL synthesized wireless microphone system that operates in the frequency range of UHF 760 - 950 MHz. It has a built-in sophisticated CPU that can automatically differentiate the receiving signal strength from the 2 antennas of the receiver and adjust the system to the antenna that has the stronger receiving signal to avoid signal dropouts and noise interference. The system is also equipped with the latest “NOISE LOCK” dual-squelch circuitry to prevent undesired random noise interference.
