LECTROSONICS IFBT2.0

This Lectrosonics Dual Channel IFB Transmitter is designed with broadcast studios and location sound mixing carts in mind with a ½ rack, dual-channel transmitter, equalling the rack density of the older T4 units. The Lectrosonics IFBT2.0 is the modern successor to the venerable IFBT4 – a dual-channel package in a 1/2 rack enclosure, offering the same rack density (4 channels in 1RU) with modern, menu-driven connectivity including analog mic and line level, Dante™ and AES digital, RTS, and ClearCom, a rich interface with colour LCD and tactile buttons, Wireless Designer compatibility, and a wide range of menu-selectable RF power settings.

Features: 

• RF power settings at 10, 25, 50, 100, and 250 mW (North American versions), and 10, 25, and 50 mW (International versions).
• AES and Dante digital connectivity
• Analog mic level, line level, ClearCom and RTS inputs, including DC blocking for “wet” signals
• Menu-driven control for RF power, frequency, compatibility modes, transmit status, input type, test tone generation, and more
• Wireless Designer compatible (WD v2.1.10 and higher for both Mac and PC)
• USB-C for Wireless Designer connection and firmware updating
• Ethernet connection for control/programming via Wireless Designer software
• Circulator/Isolator for high RF power with minimal intermodulation products generated
• ½ rack enclosure with two independent transmitters – equals rack density of shelf-mounted IFBT4 (4 channels in 1RU).
• Uses same rack hardware as M2T and DSQD
• Hirose 4-pin DC power connector (DCR15/1A8U-H power supply included with unit)
• Ultra-quiet fan cooling for use in difficult environments
• Ideal as a point-to-point audio transmitting using NU/EU Hybrid modes for full fidelity

The IFBT2.0 has enhanced, menu-selectable input connectivity including analog line and mic level, Dante™ and AES digital, Clear-com, and RTS. The inputs are compatible with “wet” signals, allowing for use with connections where DC is present on the audio lines. The new unit also includes USB-C and Ethernet connections for use with Wireless Designer software for system monitoring, frequency coordination, and setup.

The IFBT2.0 offers IFB, NU Hybrid (North American units), and EU Hybrid (export units) compatibility modes so that the unit can be used in IFB and other applications including point-to- point audio where sound quality is critical. The next-generation transmitter unit is fully compatible with the existing line of IFBR1B, IFBR1C (IFBlue), legacy IFBR1 and IFBR1A receivers; and all Digital Hybrid Wireless® and current digital Lectrosonics receivers from the Venue 2 to the LR, DSQD, DCR822, DSR, and DSR4.

Three tuning ranges are available for the new IFBT2.0: A1 (470-537 MHz), B1 (537-614 MHz) and C1 (614-692 MHz). These versions exactly match the currently available IFBR1B and IFBR1C (IFBlue) receiver packs and together cover the available UHF TV frequencies for most regions.

The IFBT2.0 offers user selectable RF power settings at  and 10, 25, and 50 mW. A circulator/isolator is employed on each channel, allowing RF signals to pass through to the antennas, while blocking external signals from entered the transmitter output sections. This greatly reduces the generation of intermodulation products.

Future firmware updates can be installed in the IFBT2.0 in the field via the USB-C jack on the front panel of the unit. The unit comes standard with rack mounting hardware and can be co-racked with Lectrosonics M2T or DSQD units or racked singly with the optional RMPRM2T-1 kit. The front panel features a colour LCD for menu navigation and monitoring, and tactile buttons for ease of use and longevity.
