Relacart systems installed across the redeveloped Hungaroring, Hungary's F1 circuit
Relacart is a wireless audio manufacturer founded in 1994 in China, known today for three things: the country's first microphone with a built-in transmitting antenna, its first Dante microphone (TDN1), and a conference and performance product range that now runs government halls, universities and Formula 1 venues across Asia, South America and Europe.
Thirty-two years is a long time in audio, and most of it happened before "wireless" became the industry's favorite word. This is the short version of how a microphone workshop became a system maker - and why the milestones still matter when you are choosing who builds your meeting room.
1994-2000: The Antenna Goes Inside the Microphone
The company's first product, the MR-280, was China's first wireless microphone with a built-in transmitting antenna - a packaging decision that quietly became an engineering philosophy: the radio and the microphone belong in one design, not one bolted onto the other. In 2000 the firm shipped a 32-channel four-group professional console that was the first of its kind in China, putting the company on both sides of the stage and the desk.
That dual identity - radio plus audio - still shows up in the catalog: receivers with built-in spectrum analysis, and mixers with Dante networking such as the MIXX series.
2015: Dante, Early and Deliberately
In 2015 Relacart became one of the earliest Dante adopters among Chinese audio manufacturers and launched the TDN1, the country's first Dante microphone. The same year brought the WAM-432, China's first four-channel true diversity wireless mixing system - the ancestor of today's UR-D line.
The bet aged well. Networked audio is now the default in conference AV, and Relacart's current conference lines - the UR-2Q quad-channel true diversity receiver, the WDC-903 wireless discussion system, the CS-302 wired system - all carry Dante interfaces, so a venue can start analog-simple and grow network-first without replacing the microphone layer.

2021-2023: Systems, Not Boxes
The recent milestones read as a shift from products to systems. In 2021 came the CS-302 Dante hand-in-hand conference system and the PM-320 true diversity in-ear monitoring system. In 2023, the HR-32 series added a built-in spectrum analyzer to a wideband digital wireless platform, with the RWW3.0 management software behind it.
The engineering base under all of it: 11 national patent certificates spanning design, utility and invention patents, 25 software copyrights, ISO quality management certification, and FCC, CE, RoHS and CB certifications on the export lines.
Where Those Systems Work Now
The reference list has gone global in the last two years. A XXIII ASSAL/IAIS insurance regulators' summit in Latin America ran on UR-2Q receivers with Dante recording; a presidential address in Peru used the same true diversity platform; nine UR-2Q receivers and twenty-two R-32AU directional antennas now serve Hungary's Hungaroring F1 circuit; and government offices in the Philippines run CS-302 wired discussion systems in daily service.
The pattern across them is the one this story has traced since 1994: radio done seriously, audio done seriously, and the two designed together. See the Hungaroring F1 deployment and the ASSAL/IAIS summit deployment for the engineering details.

- A catalog where wireless microphones, discussion systems, ceiling arrays and Dante mixers are designed to interoperate, not just coexist.
- Patents and certifications you can verify: 11 patent certificates, 25 software copyrights, ISO, FCC, CE, RoHS, CB.
- Milestone hardware still in service: TDN1 descendants on Dante networks since 2015.
- Reference sites on four continents, from government halls to F1 grandstands.
- A company that publishes its deployment templates - because repeatable engineering, not one-off heroics, is the real product.
When was Relacart founded?
In 1994, which makes 2026 the company's 32nd year of wireless audio.
What was Relacart's first product?
The MR-280, China's first wireless microphone with a built-in transmitting antenna.
Does Relacart support Dante?
Yes - since 2015. Relacart was among the earliest Chinese audio manufacturers to adopt Dante and launched TDN1, the country's first Dante microphone. Today's UR-2Q, WDC-903 and CS-302 all include Dante interfaces.
Where are Relacart systems installed?
Recent public deployments include the ASSAL/IAIS regulators' summit in Latin America, a Peruvian presidential address, the Hungaroring F1 circuit in Hungary, and the Philippine Charity Sweepstakes Office, among university and enterprise sites.
