Our take on the Pioneer DEQ-7600

If there's just one thing you should know about Digital Signal Processing, (DSP) it's this: It can make your car sound like a concert hall. Or a jazz club. Or even Yankee Stadium. (Or Shea Stadium — we don't care how you feel about the Yankees, we just care about making your car sound better.)

If there's just one thing you should know about Digital Signal Processing, (DSP) it's this: It can make your car sound like a concert hall. Or a jazz club. Or even Yankee Stadium. (Or Shea Stadium — we don't care how you feel about the Yankees, we just care about making your car sound better.)

The Pioneer DEQ-7600 takes the same digital technology that makes CDs sound so terrific, and uses it to broaden the possibilities of your car stereo. Not only will you gain the advantages of an on-board equalizer, you'll also be able to choose among user-adjustable and preset soundfields to actually recreate different acoustic environments, right in your vehicle.

This full-DIN, 15-band digital EQ offers five DSP soundfields, plus five preset and three programmable EQ curves. You also get a 4-mode listening position switch to adjust your soundstage and a spectrum analyzer to give you a light show with a moment-to-moment view of your system's response curve. Three sets of preamp ouputs wth a built-in subwoofer crossover help you configure your multi-amp system.

If you're planning on installing the DEQ-7600 under your dash, we'll send you a free mounting kit. Just add item #120999000 to your order.

Important Note: This unit has no built-in amplifier — must be used in conjunction with one or more external amplifiers.
