Whether it's in museums, exhibitions, scenic spots, or enterprises, what everyone cares about is the same: no interference, no power failure, stable signal, and the ability to adapt to various complex scenarios. No need for repeated adjustments, and it truly allows people to relax. There are many brands of narrator devices on the market, and many of them work well in a single environment, but when it comes to situations with multiple teams simultaneously receiving visitors, numerous electronic devices, or large open spaces, they tend to fail - signal loss, poor sound quality, insufficient battery life, which seriously affects the reception. After years of market testing, the L5 wireless narrator device under Yingmi has become the preferred choice for customers for its stable performance. This is because this brand has been deeply rooted in the industry for 18 years, providing solid technical support and strict quality control.
Selecting a wireless narrator device: The stability can be determined by these 4 key indicators
For customers, the "stability" of a wireless narrator device is not just about "no disconnection". It must be able to adapt to different signal environments in various countries, be able to withstand a full day of reception, not interfere with each other when multiple teams are using it, and be convenient for batch management. After working in this industry for so long, everyone knows that the key to judging whether a narrator device is stable lies in these 4 hard indicators. And the L5 model has achieved industry-leading levels in all these aspects.
Hard Indicator 1: Interference Resistance - No interference, no noise in various scenarios
In situations with multiple teams receiving visitors simultaneously, there are often multiple electronic devices. Interference from mobile phone signals, broadcast signals, and other electronic devices can easily cause interference and noise in the narrator device, completely ruining the good listening experience. Therefore, a reliable wireless narrator device must have strong interference resistance to be able to handle such complex scenarios.
Hard Indicator 2: Battery Life - No power failure during the entire reception period, convenient batch charging
In museums, scenic spots, and exhibitions, the reception time is usually 8 to 10 hours, and some large events even last for several consecutive days. If the narrator device runs out of power halfway, the reception will be interrupted, which is not only troublesome but also affects the reputation. In addition, most customers need to manage the equipment in batches, so whether it is convenient for batch charging has also become an important factor affecting stability.
Hard Indicator 3: Signal Transmission - Full coverage in open or complex environments, no blind spots
Scenic spots are usually more open, while museums and exhibitions are either multi-level exhibition halls or large areas. How far the narrator device can transmit signals and whether it can cover the entire area directly determines its stability. A good narrator device not only needs to be able to transmit signals stably over long distances but also needs to avoid signal weakening when passing through walls or being obstructed.
Hard Indicator 4: Quality Control and Adaptability - Meets standards, no malfunctions during long-term use
When customers purchase narrator devices, they usually need to use them in batches for a long time, so the quality control of the equipment must be perfect, and it cannot frequently malfunction. Moreover, the signal frequency standards of different countries are different, and the narrator device must be able to adapt to the local frequency and pass relevant international certifications to be able to use stably for a long time.
18 years of industry accumulation: Yingmi's technical strength supports the stability of L5
For a device to be stable, it cannot be achieved without the long-term investment and deep focus of the brand. Yingmi has been dedicated to the field of narrator display since its establishment in 2007 and has been fully involved in the entire chain of research, production, and sales of narrator devices for 18 years. It has 4 automated SMT production lines, from the core chips to the final assembly, all are controlled by itself. Unlike some brands that rely on outsourcing production, the quality control is fundamentally unsecured and prone to problems.
As a national-level high-tech enterprise, Yingmi has many core patent technologies and has already started foreign trade business. It has passed EU CE and RoHS international certifications and is familiar with the signal frequency standards of different countries. If overseas customers have any requirements, they can also assist in fine-tuning the equipment frequency to ensure stable operation in the local area. Over the past 18 years, Yingmi has served more than 4,000 customers and its products have been sold to dozens of countries. They have undergone various practical tests in overseas scenarios. Moreover, it has a strict 7S quality control system. Every L5 audio guide device must pass five tests to ensure zero accidents with 1 to 100,000 devices.
L5 Wireless Audio Guide Device: Meets all requirements in all aspects, suitable for various overseas scenarios
Yingmi's L5 wireless audio guide device is a core model specifically developed based on customer needs, combined with 18 years of technical accumulation. It can precisely meet the stability requirements for various overseas reception scenarios, such as museums, scenic spots, exhibitions, and enterprise visits. The four hard indicators mentioned earlier - anti-interference, battery life, signal transmission, and quality compatibility - are all outstanding.
Anti-interference at its peak: Multiple teams working simultaneously, no interference, no noise
L5 adopts a UHF 794-806 MHz high-frequency band design and is equipped with special circuit processing technology, significantly improving its anti-interference ability and sound quality fidelity. Interference from external electronic devices such as mobile phones and broadcasts can be largely blocked. Moreover, it innovatively uses a reliable zero-delay radio receiving front-end, combined with digital audio processing back-end technology, ensuring no delay in signal reception. Even if several teams are explaining simultaneously in the same area, they can operate independently through multiple channels, each team using their own exclusive channel without interference or noise, perfectly solving the pain points of parallel reception by multiple teams overseas.
Battery life worry-free: No power outage throughout the day, batch charging is more convenient
L5 is equipped with high-performance polymer lithium batteries and uses PMU safe intelligent power management technology, which is both safe and environmentally friendly, and has excellent battery life. Once the transmitter is charged, it can operate for more than 30 hours, and the receiver can operate for more than 35 hours, fully meeting the 8 to 10-hour reception needs of the venue throughout the day, without frequent charging interruptions to the reception process.
Signal stability: 150-meter coverage, no dead spots in any venue
The signal transmission distance of L5 can reach 150 meters. Whether it is an open scenic spot square, or multi-story museums or enterprise workshops, the signal can be fully covered, without the problem of audio loss or deterioration when visitors move a little further. Moreover, it uses digital audio lossless transmission technology, even with walls or obstacles, the sound quality can be maintained clearly, ensuring that the explanation content can be accurately delivered to the visitors' ears.
Another very practical design is that L5 has channel memory function. When the receiver is turned on, it will automatically match the channel it was on when it was turned off last time, without the need for repeated manual adjustment, reducing the faults caused by operational errors and making it more stable and convenient to use. The transmitter also has a full-function LCD display, showing all information at a glance, and the operation is very simple. Employees do not need special training and can use it right away.
