Wireless conference microphone

Product parameters:
Built in frequency search function, infrared frequency matching, digital processing, 10 sets of overlapping machines can be used at the same time, 40 rooms can be installed in a single frequency band, the operating distance is 40-100 meters, 600 megabytes to 800 megabytes can be customized, S2/S4/S8 universal
Wireless infrared frequency matching, 100 frequency points per channel. Two channels of 200 frequencies are suitable for multiple computers to use at the same time. There are built-in multi band selectable frequency bands (the specific frequency band is subject to the factory default, and the maximum number of frequency points is 640). With its own advanced frequency scanning function, it can effectively prevent serial frequency and external interference. Debugging truly realizes intelligent operation and easily completes project debugging. Three section receiving distance conversion, effective distance 30 meters/60 meters/90 meters optional, suitable for various occasions: KTV private rooms, outdoor performances, campus hosts, etc. The most stable transmission mode in the current radio is UHF signal frequency band transmission.
Features:
*Two channel UHF wireless network, each channel has 400 built-in frequencies for selection (each channel has four band frequency conversion, subject to the actual factory band)
*Built in advanced frequency sweep function, which can automatically skip the frequency being used and other clutter frequencies to avoid serial frequency interference
*Built in three-stage power regulation, with the distance of each stage increasing by about 30 meters, which is convenient for engineering installation
*Equipped with LCD display to feed back the working state of the system in real time
*Microphone supports one button mute replacement without delay
*Infrared automatic frequency matching, ACT automatic frequency selection
*Microphone aluminum alloy shell, durable, 2 microphones can be interchanged
*The power memory function can be controlled by a sequencer
*Built in moderate howling suppression function, which can effectively reduce the degree of howling
*Built in battery monitoring function, real-time display of battery power in the conference seat, low battery flashing prompt function, dual power supply design with 4500 mA lithium battery, four No. 5 batteries, pluggable charging bank, direct power supply through Huawei Type-C port, fast charging function, optional intelligent fast charging box, 5 minutes of charging, 2 hours of operation (80 minutes of charging, 28 hours of operation)
*Handheld microphone and conference unit can be mixed
*Anti cell phone battery wave interference
*Frequency range: 520MZH-570MZH, 531MZH-590MZH, 612MZH-672MZH, 634MZH-692MZH, 715MZH-762MZH, 735MZH-782MZH, 795MZH-845MZH, 850MZH-890MZH multi band, each interval frequency is 250HZ (the specific frequency point is subject to the factory default)
*It supports the use of multiple stacked machines, and at most 20 stacked machines can be used with one driven by two. At the same time, more than 100 stacked machines can be used without serial frequency interference
*Transmission power: 10db
*Working range: 40-100m, switch touch type (factory default)
