you will also fade out many music signals which you'd actually wish to keep. Additionally, cutting these
midrange frequencies also means that your P.A. system loses power and performance.
In theory, a parametric EQ can be used to suppress feedback by means of high filter qualities. However, your
tweeters may well have gone up in smoke before you've found the frequency at which feedback occurs and
managed to eliminate it by adjusting the filter frequency, bandwidth and gain accordingly. For this reason, the
FEEDBACK DESTROYER also uses a highly optimized version of the automated, fully parametric filters we
designed for the Behringer ULTRA-CURVE. With the FEEDBACK DESTROYER your P.A. system will be
under your control again!
Unlike many conventional equalizers, the FEEDBACK DESTROYER provides an impressive range of fea-
tures:
If required, the FEEDBACK DESTROYER detects and suppresses feedback automatically by analyzing
the music signal and determining the frequency of the interference signal. Additionally, it calculates the
filter quality and attenuation necessary to fade out feedback. The entire process does not take more than
a fraction of a second and can be performed simultaneously for all 24 filters!
The FEEDBACK DESTROYER calculates the filter quality with such a high precision that nothing but the
feedback signal will be filtered, while retaining the original music signal. This means increased P.A. head-
room and a more balanced, powerful and transparent sound image.
With the FEEDBACK DESTROYER almost all of the power delivered by the amps will reach the speak-
ers, because the precisely set, narrow-band filters reduce energy losses to a minimum.
The filters can be operated both in manual and automatic mode. Naturally, you can combine both modes
in single programs.
Clearly structured entry keys give you direct access to essential parameters, while the jog wheel allows
you to conveniently adjust them as desired. Favorite settings can be stored in 10 preset programs. Of
course, the FEEDBACK DESTROYER fully integrates into any MIDI system.
This enormous processing power is provided by a "software-separated" 24-bit Dual-Engine processor.
The FEEDBACK DESTROYER precisely converts your music with 20-bit AD/DA converters using a pro-
level sampling rate of 48 kHz. The high-grade components and circuitry make sure that the quality of the
24 fully parametric EQ's meets studio standards.
Quick filter settings can be realized by using standard ISO values for the allocation of frequency bands.
Subsequently, you can fine tune the frequency of your choice.
