Product Introduction:
YINGMI L8 Many-to-many tour guide device redefines collaborative
group communication with its innovative multi-speaker interaction
design. Operating in the UHF 663-694MHz band (customizable
frequency available), it supports seamless switching between 3-5
guides/speakers while connecting to unlimited receivers, breaking
the limitation of single-speaker traditional devices. With a 300m
long communication range, 150 adjustable channels, and a 16g
ultra-light earhook receiver, this Many-to-many wireless tour guide
device solves difficulties like rigid communication and signal instability in multi-expert
collaborative scenarios.
