Wireless Microphone
The 5000 Series wireless microphones systems are ideal for houses of worship, schools, fitness clubs and many other applications. The new 5000 Series operates in the 576-698mHz bands (on bands E01, F01, G02 & H01) with up to sixteen simultaneous systems possible within each group and even more with combined groups. Transmitter options include the WM-5225 condenser handheld, WM-5265 dynamic hand-held, WM-5270 dynamic hand-held & WM-5325 body-pack (which accept any of several lapel & headset mic options). All transmitters can be set to any of 64 UHF frequencies and are powered by a single AA battery for ten hours of continuous operation. Most (except for WM-5270) can also work with rechargeable NiMH AA batteries which can be charged directly inside the mic with optional charging stations. Receiver models include the rack-mountable WT-5800 true diversity 64-channel wireless tuner & WT-5805 space diversity 64-channel wireless tuners, as well as the portable WT-5810 space diversity 16-channel wireless tuner. All 5000 Series receivers feature a frequency scanning function and transmitter battery status indicator.

Others Microphones
We also selling different type microphones such as desktop type microphone, Clipped type microphone and lavalier type microphone and more as per our clients requirements.
Desktop type microphones for use in public address, paging and radio Communication systems. Ideal applications include restaurants, offices, warehouses, transportation terminals, dispatch centers and entertainment facilities.
Clipped type microphone is High intelligibility for speech and vocal applications.
A lavalier microphones or lavalier (also known as a lav, lapel mic, clip mic or personal mic). This type microphones is designed with a focus on clear, accurate voice reproduction with maximum intelligibility, making it ideal for such applications as lectures and religious services. It is equipped with an electret condenser microphones element that has a hypercardioid pickup pattern, and which rejects undesirable off-axis sound, to minimize potential feedback.
