The Sabine FBX-2400 is a 2-channel digital notch filter feedback suppressor wit twelve bands per channel. It can control feedback during the program, not just at setup time. This means that if feedback occurs during a crucial moment, the FBX places a filter that eliminates the feedback - without adversely affecting sound quality. This is done through its SMARTFilter technology, which quickly, precisely, and automatically locates the exact frequency band that is feeding back and removes it. Perfect for getting the sound you want without compromising quality.
