IFB (Interruptible FoldBack) transmitter base station, the IFBT2.0: B1 (537-614 MHz). The new unit is in a ½ rack chassis and features two independent transmitters, equaling the rack density of the older T4 unit. 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.
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.
