AFB-250 is designed to modulate radio signals from two receiving antennas to one optical Neutrik Duo APC output. Any passive or active antenna can be plugged in as it provides DC feed. DC feeds are protected from short circuits. An RF peak led indicates if the RF field is too strong. A built-in 10dB RF attenuator can be activated at the start-up of the device. With its rugged housing and 12V on XLR4 power, it is designed for a location or live market.

Use AFB-250 with the following products: AFR-200, ACH-642, and ACH862.
