This frequency agile IFB transmitter is designed for use in broadcast, motion picture, theater, and stage applications where extended operating range and high quality audio are essential. Delivering 250 mW of output power, it works as either a stand-alone device or patched directly into popular intercom systems.256 UHF frequencies in 100kHz steps provide exceptional flexibility in coordinating frequencies in multi-channel wireless systems and avoiding interference from external RF signal sources and noise.Lectrosonics Digital Hybrid Wireless systems overcome channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor but a technique that can be accomplished only in the digital domain, even though the inputs and outputs are analog.Because it uses an analog FM link, Digital Hybrid Wireless enjoys all the benefits of conventional FM wireless systems, such as excellent range, efficient use of RF spectrum, and resistance to interference. However, unlike conventional FM systems, it does away with the analog compandor and its artifacts.This model is available in each of the following frequency blocks. Please specify when ordering.
