This high-tech processor is versatile, offering dual mode operation. It can serve as a stereo Front Of House (FOH) feedback eliminator, or you can use channel 1 for FOH (mono) and channel 2 on your monitors, making it a single unit feedback control center.

The DF1000 comes equipped with all the connectivity options you need, including 2 balanced/unbalanced inputs on combination Line-Level XLR/TRS sockets and 3-pin Euroblock connectors. Outputs are provided in the form of balanced XLR and Euroblock connectors.

In summary, the DF1000 Ultra-Fast and Fully Automatic Dual-Channel Feedback Suppression Processor is more than just a feedback suppressor. It's an advanced, high-tech solution that enhances overall audio system performance, making it an invaluable tool for any audio professional. Say goodbye to feedback forever with the DF1000.
