Used Lectrosonics IFB System T4 Transmitter + R1A Receiver Block 25

  

Used Lectrosonics IFB System: T4 Transmitter + R1A Receiver - Block 25. This used IFB system has been tested and verified working to spec by our service department. T4 includes AC power supply and antenna; R1A receivers comes with Leather Pouch. Block 25: 640.00 - 665.500 MHz. 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. 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. Microprocessor control provides user-friendly operation and eliminates transients at turn-on and turn-off. The transmitter output is muted in the TUNE mode to avoid generating interference in other wireless systems while scrolling up and down to change frequencies.

256 UHF frequencies in 100kHz steps. 250 mW power output for long range use. DIP switch programmable intercom input. Tx mute for frequency scrolling. Compact size for use anywhere.

The IFB R1a receiver provides simplicity and flexibility in a package that is intuitive for untrained users to operate. The receiver is housed in a rugged machined aluminum package. An optional spring-loaded belt clip (shown at right) provides a secure mounting on a wide variety of belts, pockets and fabrics. The belt clip is removable to reduce its size and allow mounting into other types of bags and belt worn mounting systems common in field production. Preset frequency can be set without power or transmitter signal.

Scan mode stores up to five additional frequencies. Multi-color LED and rotary control for programming and operation. High sensitivity for extended operating range indoors or outdoors. 8 hours battery life (alkaline). 20 hours battery life (lithium).

256 frequencies in 100 kHz increments. This particular wireless microphone device operates in portions of the 617-652 MHz or 663-698 MHz frequencies.

Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee's wireless operations on these frequencies.
