Waves Audio is now shipping the Waves X-FDBK feedback eliminator plugin. The Waves X-FDBK claims to be the first plugin to provide an automatic feedback elimination solution. Whether you’re an FOH engineer mixing for thousands or a singer performing with your own compact PA system, Waves claims that you can now get a loud, clear and feedback-free mix in seconds. This way you have one less thing to worry about and you can focus on what’s really important – your mix.
Apparently, the X-FDBK identifies the precise frequencies that cause feedback and simply cuts them, shortening the setup time of monitors and PA speakers. This plugin improves the “ringing out” process and shortens it to a matter of seconds. It identifies the feedback frequencies quickly and precisely and cuts them with a narrow notch, preserving the fidelity of the wedge or PA and enabling you to maximize the gain without getting feedback.
All you need to do is turn up the levels on your wedges and PA until they start to give feedback. Then activate the plugin and wait a few seconds until you hear the feedback disappear. The plugin’s graphic frequency spectrum shows you all feedback frequencies and the degree to which they were cut, letting you tweak them manually if you wish.
