Design
The IFB300 is a ZaxNet™ transmitter that sends high-quality, fully encrypted IFB audio, timecode, and remote control commands to Zaxcom Digital Recording Wireless transmitters and ERX receivers. The signals are carried on a single RF channel ocer 2.4 GHz which can be used license-free in almost any country.
Weighing 7.3 oz, it’s constructed from an impact-resistant metal casing that’s cool to the touch. A bright OLED display provides easy menu navigation.

New on the IFB300 is an RS422 port for direct connection to the Zaxom GUI Bridge so you can easily setup URX50/100 and remote control your wireless via any device that can access the internet.
Encrypted Audio

Audio can be simultaneously transmitted and internally recorded to a microSD card using MARF (Mobile Audio Recording Format) which eliminates file corruption common to recordings due to loss of power or early card removal.
