The Lectrosonics IFBT4 UHF transmitter is designed for use in broadcast, motion picture, theater, and stage applications where extended operating range and high-quality audio are essential. It can be used as a stand-alone device or patched directly into popular intercom systems.

Lectrosonics Digital Hybrid Wireless systems overcome channel noise in a new way, digitally encoding the audio in the transmitter and decoding it in the receiver while sending the encoded information via an analog FM wireless link. This proprietary algorithm is accomplished only in the digital domain, even though the inputs and outputs are analog.

Because it uses an analog FM link, Digital Hybrid Wireless benefits from excellent range, efficient use of the RF spectrum, and resistance to interference. Unlike conventional FM systems, it eliminates the analog compandor and its artifacts.

Microprocessor control provides user-friendly operation and eliminates transients at turn-on and turn-off. The transmitter output is muted in TUNE mode to avoid generating interference in other wireless systems while scrolling to change frequencies.
