On August 19, 2026, the 33rd Beijing International Radio, TV & Film Exhibition (BIRTV 2026) officially opened at the China International Exhibition Center in Beijing.
Relacart showcased a range of key new products and system solutions. The booth attracted strong interest, drawing numerous professionals from the broadcasting, film and television production, and sports broadcasting industries for demonstrations and discussions.
Portable Location Sound Recording Solution
The core of the Portable Location Sound Recording Solution is to integrate a multi-channel wireless recording setup—which traditionally requires multiple standalone devices, numerous cables, and multiple power supplies—into a single portable unit.
Rather than changing the professional workflow of sound recordists, the solution simplifies system deployment through integration, keeps on-site cabling more organized, and makes equipment easier to carry when moving between locations, allowing sound recordists to focus more of their attention on the sound itself.
4 Port Go Portable Multicoupler
The 4 Port Go Portable Multicoupler is designed specifically for field production. It can easily connect four HCR-30D True Diversity ENG Wireless Receivers, making multi-channel audio transmission and management more convenient when working with recorders, cameras, mixers, and other equipment, while reducing complicated cabling.
Key Features
8-channel mini XLR output
Compatible with receivers from multiple brands
Long-lasting rechargeable battery
Intelligent power-source switching
