With a prestigious heritage extending back to our heralded 30 Series equalizers, the dbx 2231 easily lives up to the reverred dbx reputation. Besides including two 31-band channels of 1/3-octave equalization, the 2231 empowers you with flexible features like our PeakPlus™ limiter circuit, and our amazing Type III™ Noise Reduction system. It also includes +12 dB input gain range; switchable + 6 or + 15 dB boost/cut range; XLR, Barrier strip, and 1/4” inputs; nonconductive nylon sliders; and an intuitive user interface with comprehensive output and gain reduction metering. As always, the inevitable result of our meticulous attention to detail and top-quality componentry is exceptional sound, performance, and reliability.
