Product Description
The UR-D1 represents Relacart's latest fully self-developed digital wireless microphone system, combining powerful performance with user-friendly operation. With a 64MHz operating bandwidth and low intermodulation distortion, the system supports up to 20 simultaneously operating transmitters within an 8MHz bandwidth and accommodates over 60 compatible channels in a single frequency band, ensuring stable wireless transmission even in congested RF environments.
Featuring 24-bit/48kHz digital audio resolution, the system surpasses all analog alternatives in reproducing nuanced sound details. With a total system latency of <3ms and a flat frequency response across 20Hz–20kHz, it accurately captures the full spectrum of vocal characteristics—from deep resonances to high-frequency details—delivering transparent, high-fidelity audio. A dynamic range exceeding 120dB ensures exceptional signal-to-noise performance.
The system incorporates intelligent predictive diversity reception technology, which proactively monitors signal quality and utilizes algorithmic optimization to maintain uninterrupted transmission stability. This makes it ideal for complex multi-channel and large-scale audio applications.
For secure communication needs, AES-256 encryption is available to protect privacy in confidential settings such as classified meetings. This encryption also eliminates RF interference by restricting reception to authorized encrypted signals.
Designed for seamless integration, the system can be easily expanded via existing Dante networks—from small conference rooms or classrooms to large-scale campus and enterprise installations. Advanced functionality allows detailed configuration management while simplifying complex channel and audio setups. Additionally, the WireMicX Wireless management system enables effortless remote maintenance, monitoring, and control for streamlined system operation.
