Our take on the Pioneer DEQ-7600

Pioneer

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.

Pioneer EQ - more bang for your buck!

Written By Eddie, Atlanta, GA on Monday, April 28, 2008
Crutchfield Customer Review (What's this?)
 
I once owned a Sound Field Processor- EQ from Alpine which looked similar to this Pioneer EQ. The Alpine Unit actually had a few more options and could change color from a red to a greenish. If money is no object, I recommend the Alpine roughly $700-$800. But if you just want to tweek your sound and have a unit that looks just as good as the Alpine for about $400-500 less, then this is by far your best choice. I am very pleased with it, and didn't go broke buying it! And Crutchfield always sends you all the information and adapters you need to get it hooked up right.

If you want to control everything in your music, and make your dash look pretty at night this is for you!! This thing can control everything, and anything.
Even though you can buy a head unit with the EQ all ready into it, this thing would still come in handy with some of the options it has. I control this more then the head unit... Simply beautiful!

this is the best sound quality equalizer i've ever seen. the sound is out of this world. if you like to hear everything in your music, this is the way to go. i've had this product for 2 years and messed up the sub output. gave it to my cuz and he's enjoying it. you can fine tune everything to the finest pin drop. i just purchase my second one, can't wait to get from iraq to hook it up in my 94'mustang gt. pioneer is one of the best salers out their for head units,eq's and inside sounds. buy this here and you will enjoy sound for the rest of you life. takes a while to fine tune everything, but it's worth every min. of it.
