Product Features
Every element of the A8 tour guide system is designed around one goal: making sure the guide's voice reaches every listener, every time, regardless of crowd size or ambient noise.
Anti-Interference Transmission
Operates on the 2.4GHz high-frequency band, maintaining a clean, stable signal even in venues dense with Wi-Fi and other wireless devices.
One-to-Many Pairing
A single transmitter pairs with multiple receivers simultaneously, so one guide can lead large groups without cross-talk from nearby systems.
Long-range battery design
Transmitter offers over 12 hours of working time, while the receiver runs over 10 hours on a single charge - enough to cover a full day of touring without a mid-tour recharge.
Long-distance stable transmission
Signal reaches up to 250 meters between transmitter and receiver, keeping the group connected even when tourists spread out across larger venues.

Product Details
A two-part system built around simplicity: the guide speaks into the transmitter, and every listener hears through a dedicated receiver.
Transmitter
Held by the guide, the transmitter turns a single voice into a stable broadcast on the 2.4GHz high-frequency band, pairing with every receiver in the group at once. It's built for one-way, live explanation - the guide speaks, and the whole group hears the same clear feed, free of interference from nearby wireless devices. Housing, logo, and frequency can all be adapted to your brand.
Receiver
Worn by each tourist, the receiver picks up a clean, interference-free signal straight from the transmitter. Light enough to wear all day around the neck or clipped on, it's built for comfort during long tours without ever pulling attention away from the experience itself. Battery capacity and housing material can be adjusted to fit your order.

Q: What does "anti-interference" mean for the A8's 2.4GHz band?
A: It means the system is engineered to hold a stable, clear signal on the 2.4GHz high-frequency band even in environments with many other wireless devices operating nearby, such as busy museums or trade show floors.
Q: How many receivers can one transmitter support?
A: The A8 transmitter is built for one-to-many pairing, allowing a single guide to broadcast to multiple receivers at once without cross-interference from other nearby systems.
Q: Is the A8 a one-way or two-way communication system?
A: The A8 is a one-way system: the guide speaks through the transmitter and tourists listen through their receivers, which keeps the audio channel focused and clear for explanation-style tours.
Q: Can we customize the A8 with our own branding?
A: Yes. Yingmi offers OEM/ODM services covering logo, frequency, battery capacity, housing material, and additional functions, with in-house prototyping and testing before mass production.
