6. APPLICATIONS
The Behringer FEEDBACK DESTROYER features a high level of flexibility not only in the field of feedback
elimination. The following chapter describes some other possible applications for your FEEDBACK
DESTROYER.
6.1 Using the FEEDBACK DESTROYER in the monitor path
Inserting the FEEDBACK DESTROYER into the monitor path of your mixing console gives you maximum
protection against annoying feedback. Monitor systems are particularly susceptible to feedback because on
stage there are usually lots of microphones and speakers located in close proximity to each other. Vocal mics
are especially critical in this context as their levels must be relatively high to be able to “compete” with other
instruments. Additionally, vocal mics are not always used at fixed positions (see 1.1.1). It has therefore
proven useful to protect the monitor paths against feedback. An agreeable side effect when using the
FEEDBACK DESTROYER in the monitor path is the positive influence on both sound and loudness of the
monitors, because filtering interference makes the monitor sound more transparent and feedback suppression
enables you to increase the volume level of the monitors (which is usually highly welcomed by the musicians
performing on stage).

6.2 Using the FEEDBACK DESTROYER in the main mix bus
The FEEDBACK DESTROYER can also be used to process main mix signals. Please consider the following
remarks:
Using the FEEDBACK DESTROYER in the main mix bus gives you the advantage that any feedback occurring
in the individual microphone channels can be eliminated with just one FEEDBACK DESTROYER. However,
this also means that “wanted” feedback (e.g. guitar feedback) will be suppressed, too. Furthermore, the
FEEDBACK DESTROYER could cause a slight manipulation of the main mix sound in extreme situations.
Before applying the FEEDBACK DESTROYER, it is therefore advisable to remove the condition causing the
feedback problems. For example, try different microphone positions! Use the FEEDBACK DESTROYER in
