dbx 2231 Graphic Equalizer

The dbx 2231 Graphic Equalizer is a dual channel 31 band equalizer with type III noise reduction designed to deliver exceptional sound, performance, and reliability. With useful audio signal processing tools and the new noise reduction stuff in the box, the dbx 2231 Graphic Equalizer delivers all the flexibility and power that professional users demand.

The dbx 2231 Graphic Equalizer is amazing. One little button. It has so much effect. The Type III® Noise Reduction is an entirely new concept... virtually instantaneous encode/decode within the circuitry of the box. The dbx started out to build the finest EQ's possible, boxes with the heritage and performance to rival their famous 30 Series EQ's. And to no one's surprise they came out awfully darn good. (Ask to see the Audio Precision plots compared to the competition.) But then, Roger (dbx chief engineer, a nice guy, as far as engineers go) got the crazy idea of putting this new noise reduction stuff in the box. The dbx listened to it and were amazed. The EQ's sounded great without it but with dbx 2231 Graphic Equalizer 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 new 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 new 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.

You used to have to settle for second best in a reasonably priced EQ but not any more. With the new dbx 2231 Graphic Equalizer you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary new design of the Type III® Noise Reduction. Check out this dbx 2231 Graphic Equalizer and you'll see, you get both More..!!!
