TOA WS-5325H UHF Headset Wireless System with WH-4000H Microphone

TOA WS-5325H G01/D04 UHF Headset Wireless System with WH-4000H Microphone


The WS-5325H includes a wireless transmitter WM-5325, a headset microphone WH-4000H, and a diversity wireless tuner WT-5810. The WM-5325 wireless transmitter has been manufactured for use with a UHF system. Thanks to the PLL-synthesizer system, 64 different operating frequencies are made available. A high output power ensures stable radio signal transmission. The WH-4000H employs an electret condenser microphone element and has been designed for use in speech reinforcement applications. The WT-5810 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.
