dbx / DBXAFS2-V

This feedback suppressor responds quickly and accurately. It automatically detects feedback frequencies and suppresses them with natural sound quality. The built-in LCD display not only makes it easier to use than previous models, but also supports quick and easy setup with the wizard function. It's recommended for preventing feedback in PA systems for live concerts, lectures, and other events.

■ Feedback Suppression
Each channel has 24 filters, automatically set to the automatically detected feedback point. A steep 1/80 octave notch filter minimizes changes in sound quality. The fixed filter eliminates feedback caused by the usage environment. The live filter tracks unexpected feedback. The two types of filters combine to effectively eliminate feedback. The latest AFS algorithm has improved accuracy, successfully reducing false detection of instruments such as flutes and keyboards.

■ Wizard Function and Intuitive Interface
The LCD display allows you to check filter settings in real time. The wizard function allows for extremely easy and speedy setup. Operation is performed using the large wheel knob on the front panel. Rotate to select and press to confirm, allowing for intuitive operation.

■ Notch Filter
Three types of notch filters allow you to select the balance between response speed and sound quality to suit the source, such as music or speech. Up to five settings can be saved internally.
