DBX 2031 Single Channel 31 Band Graphic Equalizer

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. Extremely high quality EQ patent-pending Type III Noise Reduction and the elegant new PeakPlus Limiter all in one great sounding box. Four segment LED bar graph for BOTH Gain Reduction AND Output Level offers the most comprehensive visual feedback available. Status LEDs offer visual feedback for all settings on the front panel.
