WS-300 UHF Wireless Set

WS-300

The WS-300 includes a lavalier wireless microphone and a diversity tuner. The lavalier wireless microphone has been manufactured for use with a UHF system. It employs an omni-directional electret condenser microphone element and has been designed for use in speech reinforcement applications. The built-in compressor-expander circuit minimizes the influence from ambient noise. The diversity tuner is a PLL-synthesizer controlled double superhetrodyne diversity tuner designed to be used with a UHF wireless system. It employs a compander noise reduction circuit to minimize the influence of ambient RF noise.
