Here is a plug-in for those of us in the Pro Tools Expert community that also work in live sound. Whether you’re an FOH engineer mixing for thousands or a singer performing with your own compact PA system, with X-FDBK plug-in Waves have designed this plug-in to enable you to get a loud, clear and feedback-free mix in seconds.
X-FDBK is designed to identify the precise frequencies that cause feedback and surgically cut them, with the intent to dramatically shortening the setup time of monitors and PA speakers.
Waves say that X-FDBK is the first plug-in ever to provide a complete automatic feedback suppression solution. This way you have one less thing to worry about and you can focus on what’s really important – your mix.
One of the most important steps before any soundcheck or show is “ringing out” the wedges and PA – pushing them to a volume that produces audible feedback, then identifying the feedback frequencies and cutting those frequencies using a graphic equalizer. Doing this by ear is slow, painful, imprecise, and hence not completely effective. Moreover, to avoid feedback the monitors are often being tamed; as a result, the performers can’t hear themselves loud enough.
X-FDBK is designed to dramatically improve 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 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.
The normal price for the Waves X-FDBK is $149 but for a limited period you can get it for $99
