In scenarios such as overseas business receptions, scenic area tours, factory visits, and study tour teams, clear communication in a "one-to-many" format is the key to enhancing efficiency and experience. Traditional amplification equipment has issues like noisy sound, limited coverage range, and susceptibility to interference, while ordinary wireless narrators often encounter problems such as one-way transmission, insufficient interaction, and poor battery life. This has made "Which wireless narrator is better for 'one-to-many' scenarios" a core question for overseas users when making purchases. The Yingmi 008B two-way intercom version, as a classic model that has been deeply rooted in the guiding tour industry for 18 years, focuses on "two-way interaction, ultra-long transmission range, high-definition noise reduction, and long-lasting battery life" as its core advantages. After being verified by 4,000+ government and scenic area entities worldwide, it has become the preferred solution for "one-to-many" scenarios.
As the core product of Hefei Humantek. Co., Ltd., Yingmi 008B relies on the R&D strength of a national-level high-tech enterprise and is specifically optimized for the communication pain points of "one-to-many" scenarios. From 796.0-821.0 MHz wideband transmission, two-way intercom function, to SOC embedded integrated digital noise reduction technology, -20℃ to 70℃ wide temperature adaptation, every design focuses on "efficient transmission, two-way communication, and stable durability". The product has passed EU CE and RoHS dual certifications and is compatible with the wireless communication standards of most countries in the world. Whether it is factory visits by multinational enterprises, multi-team guided tours in overseas scenic areas, or the transmission of knowledge in international study tours, Yingmi 008B interprets the core standards of "high-quality one-to-many wireless narrator" with professional performance.
I. Two-way communication + multi-channel design, breaking the barrier of one-way communication
One of the core pain points in one-to-many scenarios is the lack of interaction. Traditional presentation devices can only enable the presenter to provide information in a one-way manner, and listeners cannot promptly provide feedback when they have questions, significantly reducing communication efficiency. Yingmi 008B innovatively incorporates two-way communication functionality, upgrading one-to-many communication from "one-way indoctrination" to "two-way interaction", completely solving the interaction problem.The device is divided into a transmitter and a receiver. While the presenter uses the transmitter to give a lecture, the audience can speak and ask questions at any time through the receiver. After the signal is encrypted and transmitted, all members of the team can clearly hear it, achieving an efficient communication loop of "presenter's explanation + audience's interaction". During overseas factory visits, customers can ask real-time questions about production line details, and engineers answer them immediately through the two-way communication function, without having to suspend the trip for a group discussion; in study tour teams, students can share their observation insights at any time, and teachers respond and guide on the spot, making the learning atmosphere more active. At the same time, the device supports 23 independent channels and uses a GFSK modulation method with an anti-interference chip. When different teams use it simultaneously in the same area, the signals do not interfere with each other. Even if 10 teams are conducting one-to-many explanations simultaneously, they can maintain clear and independent communication. This combination of "two-way interaction + multi-channel anti-interference" makes one-to-many communication both efficient and flexible, suitable for various multi-person collaboration scenarios.
II. Ultra-long transmission + Strong penetration power, covering all scenarios for communication needs
In many one-to-many scenarios, such as open areas or complex building structures, the transmission distance and penetration power directly determine the communication effect. Yingmi 008B specifically enhances signal performance, allowing sound transmission to break through spatial limitations and achieve full-scenario coverage without blind spots.The equipment uses a 796.0-821.0 MHz wideband transmission. In open areas, the effective transmission distance can reach over 250 meters, far exceeding the coverage range of ordinary industry models. It fully meets the one-to-many explanation needs in large scenic areas, factory workshops, and outdoor learning bases. In terms of signal penetration power, the equipment has been specially optimized. Even when facing obstacles such as concrete walls and brick walls, it can still transmit stably. In multi-layer exhibition halls, complex factory areas, or mountainous and forested scenic spots, listeners in different corners can clearly receive the sound without signal interruption or attenuation. The transmission power is up to 15 dBm, and the receiving sensitivity is as low as -110 dBm. This ensures that even weak signals can be accurately captured. Combined with PLL oscillator technology, the frequency stability is controlled within ±2 ppm, avoiding sound lag caused by frequency drift. A multinational automotive factory used feedback. In the vast production workshop, engineers carried the transmitter and moved it along the production line for explanations. The client team 200 meters away could still clearly hear the technical details through the receiver, even when crossing multiple layers of workshop walls, the signal remained stable without interference.
III. High-definition noise reduction + Excellent sound quality, clear transmission in noisy environments
In multiple scenarios, such as factories with loud machinery, crowded tourist areas with noisy crowds, or outdoor wind sounds, complex noise disturbances often occur, making it difficult for ordinary audio equipment to filter out environmental noise, resulting in unclear audio. Yingmi 008B is equipped with SOC embedded integrated digital noise reduction technology and a high-fidelity audio processing solution, allowing high-definition sound quality to penetrate noisy environments.The frequency response range of the device is 20Hz - 16KHz, with a signal-to-noise ratio of up to 80dB and a distortion rate of less than 1%. It can accurately reproduce the details of human voices. Whether it is professional technical terms, delicate cultural explanations, or vivid educational knowledge, it can be clearly conveyed without any noise or broken sounds. Through intelligent noise reduction algorithms, it can effectively filter out environmental noise below 75 decibels. In an automotive manufacturing plant, even with the loud machinery, the audience can clearly hear the details of "This production line produces one car every 90 seconds"; in a popular tourist area with dense crowds, the sounds of shop speakers and tourists' noise will not interfere with the explanation content. Team members can focus on receiving the core information. The transmitter is equipped with a 3.5mm microphone interface and supports external professional microphones, further improving the clarity of the recording. The main speaker does not need to speak loudly; normal volume can achieve full team coverage, protecting the voice while making communication more comfortable and natural.
