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. 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.
