The XXIII Annual Conference on Regulation and Supervision of Insurance in Latin America (ASSAL/IAIS) brought together leading industry authorities and government officials, who delivered key speeches on policy interpretation and cross-border cooperation. With such a high-level agenda, the event placed extremely strict demands on the stability and clarity of the audio system. To guarantee a smooth conference, the organizer chose the Relacart UR-2Q quad-channel true diversity digital wireless microphone system.
Requirements and Solution
To meet the standards of the ASSAL/IAIS conference, the Relacart team designed the audio solution around the UR-2Q, whose core technologies precisely match the demanding scenario of an international conference. The UR-2Q also supports antenna cascading: multiple units can share a single pair of antennas without an additional antenna distributor. With more than three units, however, a distributor is still recommended to keep the signal stable.
Fault-Tolerance Requirement: No Room for Interruptions
At an event of this level, any audio drop-out or noise interference would undermine its seriousness, so the system had to keep transmitting reliably despite a complex on-site RF environment.
Strong RF anti-interference: the UR-2Q features advanced quad-channel electronic tuning with a 130 MHz switching bandwidth, providing plenty of usable frequencies even in the complex electromagnetic environment of a large international venue. The system scans the RF environment in real time, automatically calculating and assigning clean, unoccupied frequencies, achieving zero interruption throughout the conference.
Requirement for Accurate Expression
The conference covered numerous technical terms and policy details, requiring excellent speech intelligibility and fidelity, so that every speaker's tone, emotion and linguistic nuances were reproduced faithfully, free from distortion or ambient noise.
High-fidelity audio: the UR-2Q uses Relacart's proprietary DSP audio expansion algorithm to reduce noise introduced during wireless transmission and delivers 96 kHz / 24-bit audio quality. Its built-in Magic EQ digital equalizer presets shape the frequency response directly, significantly improving speech clarity, while the cardioid microphone capsule suppresses lateral ambient noise and keeps every detail of the human voice intact.
Rapid Deployment and Centralized Management
For an international high-end conference, the deployment window is extremely limited, and the event was to be livestreamed and recorded end to end, which placed clear demands on fast setup, centralized management and compatibility with livestreaming equipment.
Dante network audio protocol: the whole system is built with nothing more than network cables. Audio is routed directly to a computer through Audinate's Dante Virtual Soundcard for livestreaming and backup, while the Dante Controller software provides real-time monitoring and tuning of every device.
Results and Client Feedback
Throughout the conference, the Relacart UR-2Q system experienced no signal loss and no feedback, and its RF performance remained extremely stable. Delegates praised the speech clarity: voices stayed clear even against a noisy background. The conference technical director also highlighted the fast deployment, which greatly reduced preparation time for audio tuning, livestreaming and recording despite the scale of the event.
The successful application of the Relacart UR-2Q at the ASSAL/IAIS conference demonstrates the technical competitiveness of Chinese audio systems at high-end international events, and provides a standardized deployment template for future cross-border summits and government-level conference projects.
