Product Description

With a prestigious heritage extending back to dbx's heralded 30 Series equalizers, the dbx 2231 easily lives up to the revered dbx reputation. Besides including two 31-band channels of 1/3-octave equalization, the 2231 empowers you with flexible features like the PeakPlus limiter circuit, and the amazing Type IIITM 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 the meticulous attention to detail and top-quality componentry is exceptional sound, performance, and reliability.

The most revolutionary feature of the 2231 is the proprietary Type IIITM 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 2 EQ bands to the most important thing, the music. Further, the 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:

- dbx's revolutionary Type IIITM Noise Reduction system, which increases S/N ratio by up to 20dB
- PeakPlus limiting technology with threshold range from 0dBu to +24dBu (off)

Product Description

It's amazing. One little button. It has so much effect. The Type III Noise Reduction is a cool concept -- virtually instantaneous encode/decode within the circuitry of the box. dbx started out to build the finest EQ's possible, boxes with the heritage and performance to rival our famous 30 Series EQ's. And to no one's surprise they came out awfully darn good. But then, Roger (dbx's chief engineer, a nice guy, as far as engineers go) got the crazy idea of putting this noise reduction stuff in the box. They listened to it and were amazed. The EQ's sounded great without it but with it the performance was nothing short of incredible. Check it out yourself and see.

But hey, Roger wasn't about to stop there. PeakPlus Limiter. Who knows more about limiting than the folks at dbx; nobody, that's who. So when the guys were developing this series of EQ's they wanted something that would be unique to these EQ's. That's when Roger got another one of his bright ideas and said "I bet they'll work a lot better if there's a cool limiter built in." Next thing you know, all the guys are in the studio amazed at the limiter Roger had designed specially for the 20 Series. Once again, hearing is believing.

With a threshold range of 0 to +20dbu, the PeakPlus limiter is designed to tame your program material from the subtlest nuances to the rowdiest hits. Also, the four stage LED ladder gives you a great visual indication as to what the limiter is doing.

20 Series EQ's. You used to have to settle for second best in a reasonably priced EQ but not any more. With the 20 Series from dbx Professional Products you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary design of the Type III Noise Reduction. Check out the dbx 20 Series graphic EQ's at your pro audio outfitter. You'll see, with the 20 Series EQ's you get both -- more.

Features

- Revolutionary patent-pending instant encode/decode Type III Noise Reduction increases S/N ratio by up to 20dB.
- PeakPlus Limiter (also patent pending) threshold range from 0dBu to +20dBu
- Four segment LED bargraph for both Gain Reduction and Output Level.
- Status LEDs offer visual feedback for all settings on the front panel.
