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, agonizing, imprecise, and not completely effective. Moreover, in order to avoid feedback, the monitors are often being tamed; as a result, the performers can’t hear themselves loudly enough.
Waves X-FDBK is the first plugin ever to provide an automatic and fully effective feedback elimination solution. Whether for a FOH engineer mixing for thousands or a singer performing with its own compact PA system, the plug-in can be a precious tool to get a loud, clear and feedback-free mix in seconds.
X-FDBK identifies the precise frequencies that cause feedback and surgically cuts them, dramatically 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 the user to maximize the gain without getting feedback.
All the user needs to do is turn up the levels on the wedge monitors and PA until they start to feedback. Then activate the plugin and wait a few seconds until the feedback disappears. The plugin's graphic frequency spectrum shows all feedback frequencies and the degree to which they were cut, allowing the sound engineer to tweak them manually if it so wishes. Inserted in the live mix during a performance, the plug-in allows monitors and PA to be feedback-free.
