Those who work in high-end reception scenarios such as enterprise exhibition halls, museums or government service centers all know that the zoned interpretation system is no longer an optional thing – whether multiple teams can visit simultaneously without fighting, whether the interpretation content can be delivered accurately, and even the professional feel of the venue all depend on it to support. However, there are too many manufacturers in the market doing this, and their levels vary greatly: some devices are not accurately positioned, and one side speaks Chinese while the other suddenly switches to English. Some people just don’t care about after-sales service after purchasing, and when problems occur, you can’t find anyone. Some don’t even have overseas compliance certifications, and they get stuck directly during customs clearance. Overseas users who want to choose a reliable one often feel overwhelmed: the parameters are like a mysterious book, the quality is uncertain, and the service is not guaranteed.

Our Yingmi MC200 multi-channel zoned interpretation system?has been sent to Europe, America and Asia all year round. Many overseas venues have been using it for several years without any problems. Today, based on our practical experience of over a thousand projects both at home and abroad, we will sort out for overseas friends how to make choices without falling into traps from the aspects of technology, quality and service.

I.?Check if the technology is solid: If these three indicators are not good, don’t take it no matter how cheap it is

To put it simply, the core of a zoned explanation system?is to “make sound when it should and mute when it should, and ensure that different areas do not disturb each other”. If the technology is not up to standard, buying it will just be a nuisance. When overseas friends are making a choice, don’t be fooled by the exaggerated promotions of the manufacturers. Just focus on these three practical indicators:

1. Accuracy of positioning: Centimeter-level positioning is sufficient.

A good system should achieve the goal of “wherever the person goes, the explanation follows”, as the positioning accuracy directly determines the experience. Nowadays, the technologies in the market are divided into three grades, and it’s easy to tell the good from the bad at a glance:

The best ones are UWB ultra-wideband or LD high-precision multi-frequency positioning, with an accuracy of ±10 centimeters. They have a fast response and are resistant to interference. Most high-end exhibition halls use these. Our MC200 uses our self-developed LD technology. After testing over 200 projects, in an exhibition hall with a large number of exhibits and a diverse crowd, the false trigger rate is less than 0.5%. It is basically impossible for the situation where “the explanation starts before the person arrives” to occur.

The medium one is Bluetooth AOA positioning, with an accuracy of about 1 meter. If the exhibition area is large, it’s okay to use, but it can get chaotic when there are many people.

The worst option is the regular Bluetooth or Wi-Fi positioning, with an error of up to 3 to 5 meters. Cross-zone and delay are common issues, and they can only be used for temporary exhibitions.

When overseas friends are making a selection, don’t just listen to what the manufacturer says. You must ask them to provide actual case videos or apply for samples to test yourself – for instance, simulate two or three teams crossing paths to see if there will be any crosstalk and explain whether the switching is smooth during movement. We offer overseas customers a 3-day free sample test. You can simulate real scenarios on site as you like. Whether it’s good or not, you’ll know best after experiencing it yourself.

2. Is the sound good? Only when it can be heard clearly without any crosstalk can it be considered qualified

The environment in the exhibition hall is already complex: the exhibition areas are close to each other, there are many people and it’s noisy. If the sound is not handled well, the experience will be directly disappointing. A reliable manufacturer should make sufficient efforts in these three aspects:

– Non-interference: Dual noise reduction of “physical isolation + digital algorithm” should be adopted to ensure that sounds in different areas travel independently. Our MC200 is equipped with an SOC embedded noise reduction system that can filter out 85% of the noise. Even if two teams visit side by side within 5 meters, listening to Chinese on one side and English on the other, they won’t interfere with each other.

– Smooth transition: When moving from one area to another, the sound should transition gradually and not suddenly cut off or explode. We set the fade-in and fade-out to 0.8 to 1.2 seconds. Some small manufacturers, for the sake of convenience, directly force it on. Not only do tourists get startled, but they are also likely to miss the content.

The sound quality must be clear: Digital wireless transmission should be used, and the power amplifier circuit should be adjusted properly to ensure that the sound is not distorted and has no delay. Previously, in a noisy exhibition with 85 decibels, we tested that the voice clarity of our MC200 could still remain above 89%, allowing visitors to hear clearly without getting very close.

It is suggested that overseas friends ask the manufacturer to provide a test audio or video connection to observe the effect in the actual venue – focus on listening to the sound quality when there are many people and it is noisy, as well as whether there will be crosslink when multiple teams use it simultaneously. Don’t just look at the parameters and talk on paper.

3. Stability: Whether it can be used for a long time depends on the details

Once overseas venues are put into use, they basically operate non-stop. 7× 24-hour operation is a common occurrence. If the system keeps having problems, it will greatly affect the work. Whether it is stable or not mainly depends on these three points

– Anti-interference capability: There are a bunch of electronic devices such as mobile phones, computers and interactive screens in the exhibition hall. The system must be able to avoid these interferences. Our MC200 supports 16 independent channels and can automatically skip frequencies. Even if hundreds of devices are used together at the exhibition, there will be no lag.

– Durability of the equipment: The casing must be made of strong materials and also be waterproof and moisture-proof – after all, the climate overseas varies greatly. Southeast Asia is humid and Europe is cold in winter. The equipment must be able to withstand it. Our equipment is made to the IP54 waterproof standard and has passed high and low temperature tests ranging from -20℃ to 50℃. You can use it with confidence wherever you want.

– Is the battery life sufficient? The receiver needs to last for a whole day after a single charge. Otherwise, the visit would have to be interrupted at noon to charge it, which is too troublesome. Our MC200 adopts PUM power management technology, which can last for 12 hours at a time. The accompanying charging case can charge 50 units at a time and also comes with ultraviolet disinfection, saving time and being hygienic.

II.?Let’s look at quality compliance: If these two points are not met in overseas markets, even if you buy it, you won’t be able to use it

When overseas friends are making a choice, don’t just focus on the technical parameters. You also need to pay close attention to the quality and compliance. Otherwise, the product you buy might not even be usable

1.Whether the certifications are complete or not

Different countries have different requirements for electronic devices. Without key certifications, they can’t even pass customs clearance, let alone be used.

In Europe, both CE and ROHS certifications are required. One ensures electromagnetic compatibility, and the other guarantees environmental protection. In North America, FCC certification is required to avoid interfering with local radio.

If you want to choose a reliable manufacturer, it’s best to check whether they have ISO9001 quality management system and ISO4001 environmental management system certifications. This can show that their production processes are standardized and they won’t make good equipment today but bad ones tomorrow.

All of our products from Yingmi have all these certifications. Overseas customers can directly clear customs upon receiving them without having to spend extra money on rectification, which saves a lot of trouble.

2. How well are the details done: Is it the small things that show the truth

Whether the quality is good or not, don’t just listen to what the manufacturer says. Just look at a few small details and you’ll know

– Equipment workmanship: A good device has a shell that feels free of burrs, the interfaces are firmly screwed on, and the feedback when pressing the buttons is clear. The casing of our MC200 is made in one piece. It can be pressed 10,000 times and dropped 500 times without any problem. We are also not afraid of the bumps during long-distance overseas transportation.

– Special scene adaptation: If it is a museum or a cultural relic museum, the equipment must have antibacterial and dust-proof designs. The earphone cases we provide are made of food-grade silicone, and the outer shell has also undergone antibacterial treatment, meeting the hygiene requirements of overseas public venues.

– Language and compatibility: The system must support multi-language interfaces and be able to connect to commonly used mobile phones and computers overseas. Our system can switch to 12 languages including Chinese, English, French and German, and is compatible with mainstream overseas devices. There will be no problems such as “incomprehensible interface” or “unable to connect to the device”.

III.Let’s look at the service: In overseas procurement, service is more important than the product

For overseas users, service is extremely crucial – time differences, distances, and language barriers are all troublesome issues. If the manufacturer’s service fails to keep up, problems can drive people crazy. When making a choice, pay close attention to these three points.

1. Is it managed throughout the entire process: Don’t leave no one to take care of it after you buy it

The zonal explanation system is not just about buying a machine. It needs to help you survey the site, set up points, and adjust parameters. All these tasks require professionals to handle. A reliable manufacturer will manage the entire process

– Pre-sale: We will help customers survey the site. For overseas customers who cannot visit in person, please provide a 3D venue map. We can then come up with a plan remotely and clearly write in both Chinese and English: how much equipment is needed, where the locations are, and how long it will take to install.

– During the sales process: Our technical team will install the equipment on-site, adjust the parameters, and teach the staff how to use it. We have cooperative service points in major regions around the world and can respond within 1-3 days.

– After-sales service: Operation manuals and video tutorials will be provided to ensure that overseas teams can quickly get started.

2. How fast is the after-sales response: Don’t be unable to find someone when problems occur

What overseas users fear most is that when their equipment breaks down and they contact the manufacturer, no one pays attention. A good manufacturer should do

– 7×24-hour availability: We have launched bilingual customer service in both Chinese and English. You can reach us via email, online chat or phone. When customers report problems, we will definitely reply within 30 minutes and provide solutions within 2 hours.

We have a cloud platform that enables real-time monitoring of equipment status. Over 90% of minor issues can be resolved remotely without having to wait for technicians to travel across countries.

– Spare parts can be delivered quickly: We have spare parts warehouses in Europe and Southeast Asia. Commonly used accessories can be delivered within 3 to 5 days, so the equipment won’t be left idle once it breaks down.

3. Are there any overseas cases? If you haven’t done any overseas projects before, choose with caution

To assess the strength of a manufacturer, the projects they have completed are the most practical.

– Have they served similar venues before? For instance, if you are a museum, check if they have provided services to other museums. We have worked for the British Museum and the National Museum of Chinese Nationalities before, so our experience is definitely sufficient.

– Are there many overseas projects? The more overseas projects a manufacturer has done, the better it understands the standards and demands of different regions. We have cases in over 20 countries, from museums in Europe to scenic spots in Southeast Asia, and we know how to adapt them.

– Good reviews from old customers: You can ask at industry exhibitions or third-party platforms. The satisfaction rate of our overseas customers can reach 98%, and over 60% of them will repurchase. The word-of-mouth is there.

IV.The three most common pitfalls in Overseas procurement that must be avoided

1. Only seeking cheapness and ignoring hidden costs

Some overseas users think that “it’s fine as long as it’s good enough” and buy cheap devices. However, they end up with a bunch of problems later on: there is no certification clearance, and they have to spend extra money to find connections. The equipment is old and broken, and the losses from maintenance and shutdown are even greater. There was a Southeast Asia exhibition hall before. They bought equipment that was 30% cheaper than the market price to save money. However, due to the lack of ROHS certification, the customs clearance was stuck for three months. The cost of repurchasing was several times more than what was saved, and the project was also delayed. It was really not worth it.

2. Just looking at the parameters without conducting actual tests

The numbers on the parameter table can be faked, but how it performs in actual use can be known just by testing. It is highly recommended that everyone ask the manufacturer to provide samples and test them in real scenarios themselves: for instance, simulate multiple teams visiting simultaneously to see if the positioning is accurate and if there will be any crosstalk. Listen to the sound quality in a noisy environment to see if it is clear. We offer our customers a 3-day free sample trial, aiming to let everyone experience it for themselves and only purchase if they find it useful.

3. Forgetting content adaptation will cause trouble in later operation

Most overseas exhibition halls require multilingual explanations. If the manufacturer does not provide content editing tools, if you want to add an exhibit explanation or modify the copy later, you have to contact them, which is both costly and time-consuming. We have specially developed a cloud platform. Overseas customers can modify the content in multiple languages and add a new exhibit explanation by themselves. It only takes 10 minutes to complete the task without bothering the technical staff.

In fact, when choosing an exhibition hall zoning explanation system, the essence is to find a reliable partner with which you can cooperate for a long time – technology determines whether the experience is good or not, quality determines whether it is durable or not, and service determines whether it is worry-free in the future. We, Yingmi, have been in business for 15 years. We have always been committed to making products with the mindset of “compliance, stability and usability”. From product selection consultation to after-sales maintenance, we aim to save overseas customers a lot of trouble.

Yingmi enables overseas tourists to “immerse themselves” in the stories behind the exhibits. Whether you are in charge of a museum, running an enterprise exhibition hall, or organizing an international exhibition, if you need a customized zoned explanation plan, choosing us, Yingmi, is the right choice. We aim to ensure that people from different languages and teams can clearly hear what they want to know. This is the original intention of developing this system.
