Digital 24-Bit Feedback Suppressor/Parametric Equalizer

  • 20-bit A/D and D/A converters with 64/128 times oversampling for ultra-high headroom and resolution
  • Automatically and "intelligently" searches out and destroys up to 12 frequencies per channel
  • 24 fully programmable parametric filters that can be set manually or via MIDI
  • "Set-and-forget" default setting enables immediate and super-easy Feedback Destroyer performance
  • Single-shot mode automatically searches and destroys feedback and locks the filter until you reset them manually
  • Auto mode continuously monitors the mix, resetting programmed filters automatically
  • Manual mode allows for setting up to 2 x 12 fully parametric filters including frequency, bandwidth and gain

You know the situation: your system is perfectly set up and carefully equalized. You've done everything possible to avoid problems. Then it happens: a mic too close to a speaker... ear-splitting feedback. Switch on a DSP1100P and you'll hear the difference immediately. Within fractions of a second, the FEEDBACK DESTROYER PRO's ingenious search algorithm locates feedback frequencies and sets extremely narrow, 1/60-octave filters, leaving the desired signal virtually untouched. The result: a rich, full sound without feedback. And without headaches.
