Wireless Audio Solution for a Luxury Sedan Launch in Guangzhou

A leading event agency partnered with Lexus to unveil its newest flagship sedan at a high-end automotive showcase in Guangzhou. The event combined a VIP reception, a live product reveal stage, and a guided media walkthrough — all running at the same time.

Pain Points

At past events, the agency's consumer-grade wireless microphones suffered signal interference from dense smartphone and Wi-Fi traffic, causing audio dropouts during press conferences. International guests from Japan and North America also needed real-time interpretation, but earlier systems required bulky equipment that clashed with the venue's minimalist design. Guides leading VIP groups likewise found older devices too visually heavy for a premium brand setting.

Solution

YingMi provided its L8 tour guide system with multi-channel interpretation receivers, enabling simultaneous English, Japanese, and Mandarin interpretation during the keynote. Strong anti-interference performance kept audio stable even at the peak moment of the unveiling, when the venue was most crowded. For the walkthrough segments, presenters used lightweight, discreet transmitters and earpieces that matched the formal dress code, letting guests move between zones without losing audio clarity.

Outcome

The four-hour program ran without a single reported audio interruption. Lexus's event team noted that the system's compact design and reliable transmission helped preserve the brand's polished presentation standard. The agency has since adopted YingMi equipment as its standard for future luxury automotive launches.
