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.

Description

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.

The most revolutionary feature of the 2231 is our proprietary Type III™ Noise Reduction system, which enables you to boost signal-to-noise ratios by up to an incredible 20dB. The result of this instant encode/decode process is that you’re no longer forced to employ drastic EQ settings in effort to reduce system noise. Instead, you’re freed to dedicate all EQ bands to the most important thing, the music. Further, our PeakPlus™ limiter technology allows you to easily safeguard your gear against hazardous dynamic surges in program material. In addition to these formidable tools, the 2231’s front panel provides at-a-glance insight as to gain reduction and output level status via its four-stage LED ladders. With such power and finesse built into such a reasonably priced package, it’s easy to see why dbx 20 Series equalizers are relied upon by studio and touring professionals the world over. With such affordable quality, there’s no longer any excuse for compromising your sound.

Features

  • Revolutionary dbx TYPE III™ Noise Reduction capable of restoring up to 20dB S/N ratio.
  • Proprietary patent-pending PeakPlus™ Limiter for system protection.
  • Switchable range between ±6dB and ±15dB.
  • Balanced inputs and outputs.
  • XLR, Barrier Strip, and 1/4” TRS connectors.
  • -12dB/+12dB input gain range.
  • 18dB/octave 40Hz Bessel Low-Cut filter.
  • Chassis/signal ground lift capability.
  • Internal power supply transformer.
  • Power-off hard-wire relay bypass with 2-second power-up delay.
