Description

Top quality 231 31-Band Graphic EQ Graphic Equalizer for sound performance enhancement

Product Features

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 EQ's sounded great without it but with it the performance was nothing short of incredible.

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 new 20 Series from Professional Products you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary new design of the Type III® Noise Reduction. Check out the 20 Series graphic EQ's at your pro audio outfitter. You'll see, with the 20 Series EQ's you get both MORE!!
