dbx 2231 Dual 31 Band Graphic Equalizer / Limiter with Type III

 
The DBX 2231 Dual 31-Band Graphic Equalizer gives you 2 channels with 31 bands each 1/3 octave to achieve the most precise tone control you can get. The DBX-2231 equalizer combines a superb EQ circuit a powerful limiter and revolutionary Type III noise reduction that increases S/N ratio by 20dB. The PeakPlus limiter's threshold ranges from 0dBu to +20dBu and can transparently tame the wildest hits or subtlest nuances of any signal. A 4-segment LED bar graph for both gain reduction and output level offers the most comprehensive visual feedback available. XLR barrier strip and 1/4" connectors; 45mm nylon sliders; and 12dB input gain stage provide pro flexibility and performance. DBX also includes status LEDs for all settings on the front panel of the 2231 Dual Graphic Equalizer.
 
DBX 2231 Dual 31 Band Graphic Equalizer Features:
  • Revolutionary instant encode/decode Type III® Noise Reduction in-circuit at the push of a button. Increases S/N ratio by up to 20dB
  • Patent-pending PeakPlus™ Limiter threshold range from 0dBu to +24dBu (off) can transparently tame the wildest hits or the subtlest nuances of any signal
  • Four segment LED bargraph for BOTH Gain Reduction AND Output Level
  • Status LEDs offer visual feedback for all settings on the front panel
