3.1 Level setting
Take care to set levels properly on the FEEDBACK DESTROYER PRO! Low levels deteriorate the dynamics of the music signal, which results in a poor, weak and noisy sound. On the other hand, excess levels overdriving the converters in the FEEDBACK DESTROYER PRO should also be avoided. Digital distortion is (unlike its analog counterpart) very unpleasant to hear as it does not occur gradually but abruptly.
Use the input level meter of the FEEDBACK DESTROYER PRO to adjust the input signal so that the Clip LED flickers only rarely. Make sure that it never lights up all the time!
3.2 Using the FEEDBACK DESTROYER PRO in the monitor path
Inserting the FEEDBACK DESTROYER PRO 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. It has therefore proven useful to protect the monitor paths against feedback. An agreeable side effect when using the FEEDBACK DESTROYER PRO 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).

3.3 Using the FEEDBACK DESTROYER PRO in the main mix bus
The FEEDBACK DESTROYER PRO can also be used to process main mix signals. Please consider the following remarks:
Using the FEEDBACK DESTROYER PRO 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 PRO. However, this also means that “wanted” feedback (e.g. guitar feedback) will be suppressed, too. Furthermore, the FEEDBACK DESTROYER PRO could cause a slight manipulation of the main mix sound in extreme
