Lectrosonics T4 Frequency-Agile Compact IFB Transmitter. The Lectrosonics IFBT4 UHF transmitter was designed for use in broadcast, motion picture, theater, and stage applications where extended operating range and high quality audio are essential. The IFBT4 can be used as a stand-alone device or patched directly into popular intercom systems.

Outstanding features include -
   Digital Hybrid Wireless™ technology
   256 UHF frequencies in 100kHz steps
   Microprocessor controlled operation
   250 mW power output for long range use
   Pilot tone squelch control
   Multi-use XLR input jack
   Built-in microphone preamp
   DIP switch programmable intercom input
   Tx mute for frequency scrolling
   Multi-function LCD display
   Compact size for use anywhere
   Rugged machined aluminum construction

    And 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.
