About the Sennheiser BF1083-UHF mikroport Transmitter HiDyn plus (674-698 Hz)

The Sennheiser BF1083-UHF is a professional bodypack transmitter designed for the SK 1083 mikroport UHF series, operating in the specific UHF frequency range of 674-698 MHz. This transmitter is engineered for critical wireless audio applications in broadcast, film, and theater where reliability, sound quality, and discreet form factor are paramount. It is designed to be worn on the body, typically under clothing, and connects to a lavalier microphone (not included) to provide hands-free, high-quality audio capture for presenters, actors, and talent. A key feature of this model is Sennheiser's proprietary HiDyn plus technology, an advanced companding system that delivers an exceptionally wide dynamic range and very low noise, ensuring that audio is transmitted with broadcast-grade clarity and fidelity, capturing both subtle nuances and loud passages without distortion.

The transmitter is built for durability and ease of use in demanding production environments. It features a robust metal casing, a clear and informative LCD screen for monitoring settings such as frequency, battery level, and audio gain, and intuitive controls for power, frequency selection, and audio level adjustment. The unit includes a locking 3.5mm mini-jack input for secure connection to the lavalier microphone and supports phantom power for electret condenser lavalier capsules. Power is supplied by a single AA battery, providing extended operational time. The BF1083-UHF is designed to work seamlessly with compatible Sennheiser receivers, such as the EM 1046 or other units in the 1000 series, forming a complete, high-performance wireless system.

This transmitter is a tool for audio professionals who require uncompromising wireless performance. Its operation in a defined UHF band requires careful frequency coordination, especially in multi-channel setups, to avoid interference. The combination of robust UHF transmission, the sonic benefits of HiDyn plus processing, and a rugged, user-friendly design makes the Sennheiser BF1083-UHF a trusted choice for capturing clean, reliable, and transparent audio in the most important live and recorded productions.
