UHF wireless microphone


The UHF wireless microphone WM series has 144 individual channels. The channels are divided into 12 groups, each with 12 different frequencies. The WM series can work with 16 individual channels active at the same time. Using extremely performance antenna, the WM3 receiver allow getting a very wide radio cover. The internal display show different information’s such as: frequency, audio signal level, radio signal level, mute and battery level. The diversity circuit and the squelch control complete the high level functions and specification of the WM series wireless microphone system. WM3 kit consists of: -- a WM3 receiver (with AC / DC adapter, 2 antennas and a 1.5 m cable with 1/4” jack plugs) -- a WM3 transmitter / handheld dynamic microphone
