Give the whole stage a voice. Voice without limits. The MUSICMATE MM-850 OpenStage wireless microphone system gives you the freedom to run a performance, event, or broadcast without the hassle of tangled cables. Four handheld microphones allow you to cover multiple vocalists, hosts, or karaoke participants simultaneously, while the digital UHF system in the 530-694 MHz band supports a stable signal on stage, in the hall, and throughout the event. A range of up to 100 m, four antennas, a 30 Hz-20 kHz frequency band, and a dynamic range of over 105 dB help maintain a clear, powerful voice, allowing the audience to hear every word, announcement, and chorus better. This is the equipment for operation from rehearsal to finale. Stable connection. ID Lock Code technology automatically pairs the transmitters with the receiver, making setup quick and predictable. Users don't waste time manually searching for settings, and the microphones can immediately support a performance, lesson, conference, or event. Up to 60 frequencies per channel and the ability to simultaneously operate multiple sets reduce the risk of interference, which is crucial in venues with numerous audio devices. This means greater peace of mind for the presenter and a smoother event, without the need to nervously check the signal every few minutes. Four Voices at Once: The four-channel design allows the MM-850 OpenStage to simultaneously support four wireless handheld microphones. This is a practical solution for duets, vocal ensembles, panel discussions, school academies, entertainment, and karaoke nights, where voices need to move quickly between participants. Each participant can move more freely, and the organizer benefits from fewer reconnections and technical interruptions. The omnidirectional pickup pattern helps pick up voices naturally, even when the microphone changes position in the hand or moves directly to another person. On-screen Control: LCD displays on the microphones and receiver show the channel, frequency, battery level, and RF and AF signals, so operators have the information they need at their fingertips. You can quickly detect low power, check the active channel, and react before a disruption occurs. The microphones have a battery life of up to 8 hours, enough for numerous rehearsals, presentations, events, and performances without frequent battery changes. XLR and 6.35mm MIX outputs make it easy to connect to a mixer, speaker, or PA system for various live events. Expand your setup. The kit includes a wireless receiver, 4 handheld microphones, 4 AA batteries, 8 anti-slip rings, a 6.35mm audio cable, a power supply, and an instruction manual, so you can quickly get your sound system ready for use. By purchasing additional MUSICMATE products, such as lighting effects, a karaoke system, an additional microphone, stands, speakers, or music gadgets, you can create a more engaging event environment. Lighting will emphasize the rhythm, karaoke will facilitate the fun, and accessories will help improve stage organization and enhance the performance experience during shows and events.
