UR-D1

Relacart UR-D1 - single-channel digital receiver of the wireless system, Dante, AES-256

The Relacart UR-D1 is a single-channel digital receiver of the next-generation wireless system, based on Relacart's proprietary digital architecture. The device is designed for demanding professional AV installations, such as conference rooms, educational spaces, broadcast studios, and advanced corporate systems. With a bandwidth of 64MHz and low intermodulation distortion, the receiver supports up to 20 simultaneous transmitters within 8MHz and over 60 channels in a single frequency band, ensuring stable transmission even in heavily loaded RF environments.

The UR-D1 offers 24-bit/48kHz digital audio quality, latency <3ms, and a flat frequency response of 20Hz-20kHz ±1dB, guaranteeing natural and transparent voice reproduction. A dynamic range of >120dB and total harmonic distortion <0.1% enable precise signal processing in applications requiring the highest sound purity.

The receiver utilizes intelligent predictive diversity reception combined with True Diversity architecture, which analyzes signal quality in real-time and automatically selects the best reception path. This solution minimizes dropouts, multipath interference, and signal fluctuations, ensuring stable transmission in multi-channel installations. In applications requiring security, the UR-D1 offers AES-256 encryption, guaranteeing protection for sensitive data transmissions and the ability to operate only with authorized encrypted signals.

The receiver is designed for seamless integration with network infrastructure - thanks to Dante, it allows for flexible signal routing and easy scaling from single rooms to extensive campus installations. The WireMicX Wireless system enables remote management, monitoring, and configuration of channels, simplifying the operation of multi-channel AV environments. The compact 1U Half-Rack housing facilitates integration into rack and mobile setups.
