The Sennheiser EM 3732 is a professional, dual-channel UHF true diversity wireless receiver, representing a high-tier solution within the evolution wireless 3000 series for demanding broadcast, large-scale touring, and major installed sound applications. Operating across an exceptionally wide frequency range from 470 to 638 MHz, this unit provides unparalleled flexibility for global frequency coordination, allowing system engineers to navigate congested RF spectrums and find clear channels reliably in any region. Housed in a robust 3U rackmount chassis, it incorporates two completely independent receiver channels, each equipped with its own sophisticated true-diversity system utilizing dual tuners and antenna inputs to ensure maximum signal integrity and eliminate dropouts caused by multipath interference and signal nulls.

Each channel of the EM 3732 is built to the highest broadcast and touring standards, featuring high sensitivity and exceptional selectivity to reject adjacent channel interference. The front panel provides comprehensive monitoring and control for both channels, with detailed metering for RF and audio levels, and intuitive navigation for frequency selection and system configuration. Advanced professional features include an integrated spectrum analyzer display for visualizing the RF landscape, automatic frequency scanning to identify open bands, and full compatibility with a wide range of Sennheiser handheld and bodypack transmitters. The audio path is engineered for absolute transparency, employing the manufacturer's proprietary wide-band companding technology to deliver a wide dynamic range, full-frequency response, and exceptionally low noise and distortion.

Constructed with a heavy-duty metal chassis for durability in touring racks and 24/7 broadcast facilities, the receiver offers extensive connectivity on its rear panel. This includes balanced XLR and unbalanced 6.3 mm jack audio outputs for each channel, along with dedicated BNC antenna inputs with loop-through outputs for daisy-chaining multiple units. The Sennheiser EM 3732 represents a benchmark in modular wireless receiver technology, providing audio professionals with a reliable, sonically pristine, and highly adaptable solution for managing two critical wireless channels in situations where absolute performance, signal stability, and operational flexibility are non-negotiable.
