The new IFBT2.0 is designed with broadcast studios and location sound mixing carts in mind with a ½ rack, dual-channel transmitter, equaling the rack density of the older T4 units. 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 and NU/EU Hybrid compatibility modes for use with all prior Lectrosonics IFB receivers including IFBR1, IFBR1A, IFBR1B, IFBR1C (IFBlue) units, along with any Hybrid receiver from Venue and Venue 2 to UCR411a, R400a, and LR, and any Digital receiver with Hybrid compatibility including DCR822, DSR, DSR4, M2Ra, and DSQD.

The Circulator/Isolator in the RF output on each channel acts as a one-way valve for RF, preventing external signals from entering the transmitters. This greatly reduces the generation intermodulation products, allowing for tighter frequency coordination, even with higher RF powers. The IFBT2.0 offers user selectable RF power settings at 10, 25, 50, 100, and 250 mW (North American versions), and 10, 25, and 50 mW (EU versions).

While designed for use as a primary IFB base-station transmitter for broadcast studios and film/TV sets, the IFBT2.0 is equally at home as an audio point-to-point audio transmitter with excellent audio fidelity using NU/EU Hybrid compat mode (flat from 40-20 kHz, with no audio companding).

Accessories

Designed as a successor to the IFBT4, the IFBT20 offers two transmitter channels, enhanced connectivity, updated interface, new form factor, and convenience features to the IFB product family. It has been designed to work with the new IFBR1B and IFBR1C receivers and is ideal for Broadcast TV News & Production, Location Sound, and backstage communication. The IFBT20 is also an ideal transmit base station for Point-to-Point audio using the full-fidelity Digital Hybrid Wireless® mode and compatible receivers. The IFBT20 includes a USB-C port for firmware updates and an IR port for fast setup with compatible receivers. A large, high resolution, backlit LCD and tactile push buttons provide an intuitive interface that is highly visible in daylight or dimly lit conditions. The half-rack transmitter provides two audio inputs which can be individually configured to be analog or digital. The input connectors are full size XLR/TRS combo types for balanced mic, line level analog or AES3 signals, and are protected from DC on the signal lines. Input preamp circuits use a special balanced amplifier with very high common mode rejection to minimize hum and noise. The modulated RF signal is filtered before and after amplification to suppress out-of-band noise and spurious signals. Dante inputs are included for installations with audio over IP. The system is designed and developed with the rugged, durable packaging you’ve come to rely on. The transmitter chassis is all-metal. The front panel is an aluminum extrusion with a durable powder coat finish. The IFBT20 half-rack transmitter features user-selectable transmission power to cover a wide varity of applications. DanteTM is a trademark of Audinate Pty Ltd. Firmware updates are made via the USB-C port on the front panel of the housing via Wireless Designer software. The procedure is very simple using a standard USB-C cable connected to a Mac or PC. Setup and adjustment are enabled through a backlit LCD, tactile buttons and an intuitive menu structure. Input gain is adjustable over a wide range in 1 dB steps to optimize modulation and limiting for maximum signal to noise ratio and minimum distortion.
