Why Audio Professionals Choose Relacart: 32 Years of Proof

Delegates at the XXIII ASSAL/IAIS insurance regulation conference in Latin America, running on Relacart UR-2Q systems

Every procurement shortlist eventually asks the same question in a different costume: why this brand and not the other five on the spreadsheet? For Relacart - the wireless audio manufacturer founded in 1994 in Guangzhou - the answer is not a slogan but a stack of verifiable things: self-developed radio technology, an in-house test system most competitors rent time on a bench to approximate, a certification portfolio that survives tender committees, and a deployment record that includes a Formula 1 circuit redevelopment and a presidential speech.

This page collects that evidence in one place, with links to the primary sources. It is written for the integrator, the rental house and the consultant who has to defend a choice in writing.

Engineering first: self-developed since day one

The company’s first product, the MR-280, was China’s first wireless microphone with a built-in transmitting antenna - a packaging decision that set the tone for three decades: radio and microphone designed as one instrument, not bolted together. That philosophy shows up in the milestones that followed. In 2015 Relacart shipped the TDN1, its first Dante microphone, joining the Audinate ecosystem years before Dante became a checkbox on conference tenders. More recently, the CONFER X digital automatic mixer - 64 inputs and 16 outputs - was developed in-house from silicon to software.

The same depth runs through the current catalogue: quad-channel true diversity receivers with 130 MHz switching bandwidth in the UR-2Q, digital wireless platforms in the UR-D series, and the ACM series of AI-assisted ceiling array microphones. A practical guide to Dante microphones in conference rooms shows how these pieces behave as a system rather than as a shelf of boxes.

The 30-item test nobody outsources

Wireless reliability is not negotiated at the factory gate - it is engineered on a test bench. Relacart runs its own RF test system, the "WIRELESS MICROPHONE TESTSYSTEM BY RELACART", covering more than 30 items: equipment current draw, antenna feed voltage, VCO voltage, local oscillator frequency, IF signal, audio response curves, weak-signal behaviour across low, mid and high bands, and XLR output verification on both channels.

Why does this matter to a buyer? Because the failure modes that embarrass installations - the drift on a hot stage, the squelch tail on a quiet panel, the channel that collides only when the LED wall powers up - are exactly the parameters this bench measures before a unit ships. It is also the reason the company can stand behind dense multi-channel racks, such as the nine UR-2Q receivers planned into a congested RF environment during the Hungaroring Formula 1 circuit redevelopment.

Certifications, trademarks and intellectual property

Tender committees do not accept enthusiasm as evidence; they accept documents. The Relacart portfolio includes:

• Certifications by market: CE (European Union), FCC (United States), CCC (China) on conference systems including WDC-903, WAM-432, CS-302 and CONFER X, plus RoHS compliance and CB-scheme test reports.
• Trademarks: registered Relacart marks in the United States and Canada, protecting buyers and authorized dealers alike.
• Patents and software: 11 national patents across design, utility-model and invention categories, and 25 software copyrights covering the DSP and control software in current systems.
• Quality management: ISO quality-management certification over the manufacturing process that turns all of the above into shippable boxes.

Deployments that answer for themselves

References are where marketing stops and evidence starts. A short selection, each with a public case study:

Selected Relacart deployments with published case studies

The full archive lives in the project section - from the Philippine Charity Sweepstakes Office council chamber running CS-302 wired discussion units to the Buddhist university in Myanmar where the same Dante philosophy drives a wireless system. Different rooms, same RF discipline.

One ecosystem instead of five vendors

A less advertised advantage: breadth. Conference discussion systems (wireless WDC series and wired CS series), Dante and analogue conference microphones, performance wireless, AI intelligent audio, antenna distribution, mixers and DSP - all under one brand and one support channel. For an integrator that means one compatibility matrix instead of five, one firmware portal, and one phone number at 9 p.m. when the room must work tomorrow.

The official FAQ and the product documentation cover the operational details; the strategic detail is that every product above shares the same test bench, the same quality system and the same RF heritage.

What this means for your next tender

How does Relacart compare with the established European brands?

On RF stability and Dante integration, the honest answer is: on par where it counts, and ahead on price-to-channel-density and support responsiveness. The 32-year record and the certification portfolio exist precisely so this comparison can be made on documents rather than impressions - start with the deployment table above.

Which series should we shortlist for a council chamber or university hall?

For wired fixed installations, the CS series (as deployed at the Philippine Charity Sweepstakes Office); for wireless flexibility, the WDC-903 (as deployed in Myanmar); where RF congestion or large stages are involved, the UR-2Q true diversity platform. Send the room drawings through the contact page and the engineering team will propose a frequency plan.

Where can we verify the brand before specifying it?

Start with the About page and the official channels listed there, then read the guide on identifying genuine Relacart products and official channels - it exists so that procurement teams can verify every claim on this page independently.
