JEF

Overview

JEF converts microphones directly to Dante with low noise mic preamps, onboard DSP, and full network and power redundancy. Remote microphone control. Simplified.

Designed for boardrooms, stadiums, and broadcast environments, JEF integrates seamlessly into any Dante or AES67 workflow. Signal processing is handled onboard, reducing reliance on external DSP and simplifying system design.

TAA compliant and backed by a 5 year advance replacement warranty, JEF is built for long term deployment in professional AV and broadcast systems.
