The Lectrosonics SRB is a compact, professional-grade dual-channel UHF wireless receiver designed for applications where space is at a premium but audio quality and reliability cannot be compromised. Housed in a robust, half-rack width metal enclosure, it provides two independent receiver channels in a single, space-efficient unit. Operating within a wide UHF frequency band, the SRB offers extensive tunability to locate clear channels in crowded RF environments, which is essential for multi-system operation in broadcast, film production, and live events. It employs Lectrosonics' advanced digital hybrid wireless technology, which combines the robust transmission of digital with the sonic transparency of analog FM, delivering exceptional audio clarity and resistance to interference.

Each of the two channels is a true diversity receiver, utilizing two separate antenna inputs to combat signal nulls and dropouts caused by multipath interference, a common issue in challenging physical environments. The receiver features a clear backlit display for each channel, showing critical information such as frequency, RF signal strength, and audio level. A sophisticated noise-operated squelch system ensures the audio output remains silent when no desired signal is present. Output options typically include both analog XLR and a digital AES3 output on a 5-pin XLR connector, providing flexible integration into both analog and digital audio workflows.

The SRB's half-rack design allows for high-density installations, enabling up to four discrete receiver channels in a standard 1U rack space. Its build quality and proven RF performance make it a reliable choice for critical audio capture where equipment footprint matters. Whether used as a standalone unit for a two-person interview or as part of a larger rack system for a multi-channel production, the Lectrosonics SRB offers a powerful, high-fidelity wireless solution in a remarkably compact form factor.
