PRODUCT DESCRIPTION
- Enhance any System The DF1000 is the ultimate choice for improving the performance of your sound system. When you get rid of feedback you can effectively turn up the output gain by as much as 10dB. This in turn gives you plenty of additional headroom without potentially destructive feedback getting in your way. Its ideal for use as a dedicated stereo front-of-house feedback eliminator or use a single channel for front-of-house and the second channel for your stage monitors. With two balanced/unbalanced inputs utilising line-level XLR/TRS combo sockets and 3-pin Euroblock connectors as well as balanced XLR and Euroblock outputs you have plenty of options to fit your system. Fully-Automatic Operation Intuitive and versatile. The Klark Teknik DF1000 automatically detects feedback and rapidly applies up to 32 precision notch filters per channel to eliminate it. Each notch filter is extremely narrow ensuring that the rest of your signal is left almost completely untouched. This instant feedback protection is perfect for both speech and music giving you a feedback-free performance for a significantly-improved overall sound. This plug-and-play processor is installed between your mixing console and your power amps. Once installed you can simply switch the power on press the front-panel Active button and youre ready to go.
