The Lectrosonics CR187 is a professional-grade, true diversity wireless receiver engineered for mission-critical audio applications in broadcast, film, and live production. Operating within a selectable frequency range, this single-channel receiver is designed to deliver exceptional audio clarity and unparalleled transmission reliability in the challenging RF environments typical of major productions. It employs Lectrosonics' proprietary Digital Hybrid Wireless technology, which transmits an analog FM carrier for robust RF performance while modulating it with a digitally encoded audio signal. This innovative approach yields the range and interference rejection of analog systems alongside the low distortion and precise frequency response of digital audio, effectively bridging the strengths of both methodologies. The unit is a cornerstone for sound mixers who require absolute confidence in their wireless audio links for talent microphones, critical plant mics, or IFB feeds.

The receiver features a sophisticated dual-antenna true diversity system with industry-leading front-end selectivity to reject off-frequency interference, even from nearby transmitters on adjacent frequencies. Its scanning and frequency coordination tools are integral, allowing users to rapidly identify clear frequencies within a crowded spectrum and manage multiple wireless systems efficiently. The chassis is constructed from a durable aluminum alloy, providing robust shielding against electromagnetic interference while effectively dissipating heat for stable operation. The intuitive front panel includes a high-contrast LCD screen that displays real-time information such as RF signal strength, audio level, frequency selection, and battery status of the paired transmitter, offering immediate situational awareness at a glance.

For integration into professional audio workflows, the CR187 provides balanced analog audio outputs via XLR connectors as well as a digital AES3 output for direct connection to digital recorders or consoles, preserving the pristine audio quality throughout the signal chain. Comprehensive networking capability via the Lectrosonics Wireless Designer software allows for remote control, monitoring, and configuration of entire wireless systems from a central computer. Built to the exacting standards for which the manufacturer is known, the receiver exemplifies a commitment to audio fidelity, RF robustness, and operational resilience, making it a trusted tool for top-tier audio professionals worldwide.
