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 over 2.4 GHz which can be used license-free in almost any country.

Weighing 207g, it's constructed from an impact-resistant metal casing that's cool to the touch. A bright OLED display provides easy menu navigation.

The TA5 audio input offers balanced stereo line level or sample rate converting AES. The BNC connector provides timecode in. There is a 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.

The IFB300 transmits using 100% digital modulation and audio is fully encrypted to keep transmissions private, just make sure you don't give the director an ERX with your teams private IFB feed.

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.

The IFB300 and ZGB (Zaxcom Gui Bridge) combo gives you the ultimate remote control in the palm of your hand. You can remotely chance frequency, input level gain, output power levels, and record status right from the palm of your hand!
