The Sennheiser EM 3532-U is a high-performance, dual-channel UHF diversity receiver module from the esteemed Mikroport series, designed for mission-critical wireless audio applications in broadcast, major live sound, and large-scale theater productions. Operating within the 674 to 698 MHz frequency range, this unit provides a stable and robust operating band, offering excellent performance in environments with significant RF activity. Housed in a substantial 3U rackmount enclosure, it incorporates two completely independent, true-diversity receiver channels, allowing for efficient and reliable management of two separate wireless microphone links—such as two lavalier microphones or a combination of handheld and bodypack systems—within a single, professional unit.

Each channel employs a sophisticated true-diversity reception system, utilizing two separate tuners and antenna inputs to continuously compare and select the strongest RF signal. This advanced architecture is highly effective at eliminating audio dropouts caused by multipath interference, which is critical when talent is moving on a stage or within a television studio. The front panel provides comprehensive controls and status indicators for both channels, enabling precise adjustment of parameters like squelch, frequency selection, and audio output levels. The audio path is engineered to broadcast standards, delivering a wide dynamic range, transparent frequency response, and very low noise through Sennheiser's advanced companding technology of its era.

Built for durability in both fixed installations and mobile racks, the receiver features a heavy-duty all-metal chassis. Its rear panel offers extensive connectivity, including balanced XLR and unbalanced 6.3 mm jack audio outputs for each channel, along with dedicated antenna inputs and loop-through outputs for daisy-chaining multiple units in large, complex systems. The Sennheiser EM 3532-U represents the pinnacle of modular wireless receiver technology from its generation, offering broadcast engineers and live sound professionals a reliable, high-performance solution for managing multiple critical wireless channels with uncompromising audio integrity and operational security in the most demanding professional environments.
