       On March 20, 2009, Shenzhen Guanguan Technology Development Co., Ltd. officially released its new-generation digital wireless audio-video tour guide system at its headquarters, with the system code named SOYO-WTGAV2009. Samples were displayed on site for guests to watch and listen to.
During on-site testing, the transmitter locator and the wireless audio-video tour guide device could both locate and accurately play corresponding video, audio, or images at distances ranging from 50 cm to 100 meters. Guests wearing Guanguan's wireless tour guide prototype and ear-hook headphones watched DVD-quality videos on the device and listened to the娓娓道来的 narration through the earphones, with the video and audio quality maintaining Guanguan's consistently high standards.
The complete success of this test marked that Guanguan Technology, while current tour guide systems still used button-based manual selection, was the first in the industry to successfully run an all-in-one wireless tour guide system compatible with video, audio, and images simultaneously. The realization of this technology also provided the most advanced digital system implementation solution for the upcoming upgrade and replacement of tour guide services in museums and tourist attractions.
The atmosphere at the release event was lively, and the guests attending were very satisfied with the system's performance over such long distances.
                  
The seventh-generation digital wireless video tour guide system solution officially released by Guanguan Technology this time has the following features:
1. Flexible transmission distance: The digital wireless tour guide system provided by Guanbiao Technology offers a variety of tour guide distance options within the range of 1 meter to 100 meters, facilitating customers to complete various tour guide tasks.
2. Provides the most complete digital wireless tour guide series solutions in the industry, combining automatic tour guide + manual wireless tour group explanation.
3. The latest technology adopts the 2.4G digital wireless transmission technology that can be used free of charge worldwide, effectively ensuring that our wireless tour guide system can be installed and used anywhere in the world without requiring any radio management approval, bringing maximum convenience to customers.
4. The 7th generation wireless tour guide device features a 2.8-inch full-color, 16:9 large-screen LCD display with QVGA image quality.
6. Provides 32-bit volume adjustment and display function: Guanbiao Technology consistently provides customers with uncompromising high-quality services. The channel display/volume display and adjustment necessary for wireless products allow customers to clearly understand the status of the product they are using, providing a true high-quality digital product experience.
7. 32-level digital volume control: Tourists and listeners can independently operate Guanbiao's wireless tour guide receiver to control the volume level. All volume control is digital, with up to 128 levels of digital volume control, allowing guests to accurately hear the voice of the tour guide/explainer.
8. Shortest delay: The audio delay transmitted wirelessly is less than 0.5ms, which is the highest standard in the industry.
Note: The minimum requirement for sound delay in a high-quality audio system is 2ms. Our products can achieve a standard of less than 0.5ms, which is the highest standard for current digital wireless audio transmission. Products currently on the market generally have a delay of 2-25ms, making them unable to be applied in the field of high-quality audio.
　　9. The highest audio sampling rate, 256k sampling rate, and HDCD sound quality with high-fidelity effect: The sampling frequency breaks through previous limitations, adopting the most faithful 64K digital audio sampling rate with 16-bit sample quantization level, ensuring sound quality from the source. After special technical processing before and after transmission, the received signal is guaranteed to maintain high-fidelity effect.
　　10. Up to 80 selectable frequency bands, easily avoiding interference frequencies: This product operates in the 2.4GHz ISM (i.e., Industrial, Scientific, and Medical) band, with 80 selectable frequency points, expandable up to 120, meeting the needs for multi-frequency and frequency hopping. To avoid the impact of interference that is prone to occur in the 2.4GHz public band on sound quality, this product provides a frequency point selection function. If strong noise occurs during operation, indicating interference at the current frequency point affecting output sound quality, a new working frequency point can be selected to maintain the product's good performance.
Note: The number of channels is determined by the program. The reason why tour guide products from other companies have fewer channels is mainly because these companies basically adopt solutions from solution providers. The most common solution can only provide 8 channels, and the channel frequencies are fixed and cannot be changed, greatly limiting customer applications.
11. Support multiple transmission modes including point-to-point and point-to-multipoint, supporting an unlimited number of receivers
12. Provide random pairing mode with Crown's unique algorithm: customers can easily perform point-to-point and point-to-group pairing according to the operation instructions. The system automatically generates random pairing codes of over 20 million, with a possible repetition probability of one in 20 million, easily ensuring that customers' privacy is not violated.
13. Encrypted transmission method: Crown's unique audio coding combined with unique encryption means ensures that the audio transmitted by our products can only be received by our customers themselves.
14. 20Hz～20KHz frequency response: Please note that this data is actual instrument test data, and should be distinguished from the exaggerated product claims of some products on the market that do not meet this specification.
15. Unique ultra-low power consumption design, providing the industry's lowest power consumption and ultra-long standby power management technology:
Crown's wireless positioning system adopts Crown Technology's unique power management technology with extremely low power consumption. In battery-powered omnidirectional wireless positioning systems, it can achieve the industry's highest record of continuous operation for more than half a year without battery replacement. At the same time, for outdoor applications, Crown can also provide solar energy storage power supply systems using solar technology, ensuring that outdoor wireless positioning systems can work continuously 365 days a year without additional power supply, effectively solving the following installation problems that have long troubled museums and tourist attractions:
Question 1: During the exhibition, the placement of display cases and exhibits sometimes cannot provide power, and traditional power-supplied wireless guide systems cannot be installed:
Answer: Using Guanbiao Technology's battery-powered omnidirectional wireless guide system positioning host, it can work continuously for 6 months without changing batteries.
Question 2: When installing wireless guide systems at tourist attractions, especially mountains, ancient buildings, etc., due to cultural relic protection or the large area of tourist attractions, it is inconvenient or impossible to provide power. Traditional wireless guide system solutions cannot work without power and cannot solve this problem.
Answer: Using Guanbiao Technology's solar power supply and energy storage system, all power relies on solar cells, and surplus electricity is stored in rechargeable batteries at any time. Combined with Guanbiao Technology's unique long-lasting power management technology, it can effectively ensure that the wireless guide system host can work continuously 365 days a year without any mains power supply. This greatly solves the shortcomings that have plagued tourist attractions and museums for many years, such as difficult power installation for wireless guide systems, poor positioning accuracy, short positioning distance, directional positioning, and unsuitability for outdoor or mobile applications.
                  
　　We sincerely welcome domestic and foreign customers to jointly explore the broad market of the new generation of all-in-one audio and video guide systems.
