The dbx 2231 boasts two 31-band channels of 1/3-octave equalization and offers a PeakPlus limiter circuit, Type III Noise Reduction system, +12 dB input gain range and switchable +6 or +15 dB boost/cut ranges for exceptional sound quality and flexible performance. It also sports XLR, Barrier strip, and 1/4'' inputs, nonconductive nylon sliders, and an intuitive user interface with comprehensive output and gain reduction metering.

Its proprietary Type III Noise Reduction system lets you boost signal-to-noise ratios by up to 20dB. This instant encode/decode process means that you're no longer forced to employ drastic EQ settings in effort to reduce system noise. And its PeakPlus limiter technology allows you to easily safeguard your gear against hazardous dynamic surges in program material. In addition to these powerful tools, the 2231's front panel provides at-a-glance monitoring of gain reduction and output level status via its four-stage LED ladders.
