Equalizer for home stereo?
I would like to play around with an equalizer (cheap) in my home stereo to
see for myself what frequency balance "appeals" to me. Whether it's the effects of the room or the speakers, I sometimes feel that I would like a little more "punch" (bass) and/or "bite" (mid/high) which I think can be provided by altering the overall response. From what I understand (very little) about equalizers, a graphic equalizer has fixed center frequencies that can be either increased or decreased - is the "Q" of the peak or dip fixed also? I'm thinking that with a parametric equalizer, I would be able to use much sharper peaks and dips within a narrower band of frequencies than what I could with a graphic equalizer, but from what I've seen on ebay, they seem to be designed more for professional use and are commonly only a single channel device - they are also much more expensive than a graphic equalizer. Any comments? John |

Any comments? The price difference is largely due to the economies of scale and because, being marketed to professionals, are built with more expensive components that provide the higher quality and reliability that pros require. -- ================================================== ====================== Michael Kesti | "And like, one and one don't make | two, one and one make one." | - The Who, Bargain |

Probably. The adapters should take care of balanced/unbalanaced interface issues. You will be giving up the advantages of the EQ's balanced I/O, but it won't matter with the short cable runs you're likely to use. Your preamp and power amp probably use -10 dBV nominal levels and the EQ's max level is +23 dBu so you will not overdrive the EQ and it will have plenty of headroom. The EQ is designed to use voltage transfer, rather than power transfer, and your preamp and power amp probably also use voltage transfer so impedance mismatch is not an issue unless you connect 10's of power amps to the EQ's output. Thanks for the help, You're welcome.

I think you'll find it depends on the source material typically. I.e. - not a constant. Whether it's the effects of the room or the speakers, I sometimes feel that I would like a little more "punch" (bass) and/or "bite" (mid/high) which I think can be provided by altering the overall response. From what I understand (very little) about equalizers, a graphic equalizer has fixed center frequencies That's normal. that can be either increased or decreased Very rarely - only on some pro type equipment. - is the "Q" of the peak or dip fixed also? Sometimes, sometimes not. I'm thinking that with a parametric equalizer, I would be able to use much sharper peaks and dips within a narrower band of frequencies than what I could with a graphic equalizer, Yes you could, but that's not typically a good example of 'room EQ'. It can be used creatively though. but from what I've seen on ebay, they seem to be designed more for professional use and are commonly only a single channel device - they are also much more expensive than a graphic equalizer. Any comments? A parametric is *way* more flexible but you need to know how to use it. Marketing ppl find it easier to sell graphic EQs. Personally I loathe them - a great way to mush up the sound. Have you considered bass and treble controls ? Graham |

Connector 'adaptors' made by the likes of Neutrik ( Swiss ) are fine but expensive. Cheaper ones aren't ( fine ) . Far better still is to buy a simple purpose made RCA jack to 1/4" lead for example and avoid any adaptors. There will be no impedance 'mismatches'. Modern gear ( even oldish ) is designed by ppl who know what needs to connect to what and why and they don't screw up like that. More relevant is the fact that 7 bands of graphic EQ is a truly awful 'blunt instrument'. You can *never* hit the frequencies that you're looking for, since each slider controls a whole *octave* ! Pros use *31* band graphics if you're aiming to emulate them ...i.e. each slider controls a 1/3 octave. To make a simple comparison - if you're into photography - a 7 band EQ is like using a throway camera while a 31 band is like a single lens reflex. I still don't like graphics though ! They don't address the real issues. If you just want to play and try it out - please don't agonise about it. You'll soon realise your bad purchases from their sound. Graham |

There are a few local dealers so I think I will see what I can find out. Thanks for the lead. John |

Any comments? If you want to fool around with an equalizer that works well in a home environment, let me recommend the Behringer PEQ 2200. You'll need some 1/4" to RCA adpators or cables to use it in a home stereo, but they are under $5 a pair at Radio Shack. If you want stereo, you'll need two PEQ 2200s as they are mono. Last time I wanted one, I found one new-in-box on eBay for under $60 shipped. It showed up in perfect shape. In use, and on the test bench its actually a pretty fine unit. |

A parametric is *way* more flexible but you need to know how to use it. Agreed. I have and routinely use a number of both parametrics and graphics. However, if you use either a lot, the hand-and-eye coordination builds up, and the greater flexibility of a parametric becomes clear. A 5+ band parametric is a good "Desert Island" tool. Marketing ppl find it easier to sell graphic EQs. The graphic is easier to use at first as the graphic layout is more intuitive - its like looking at a frequency response curve. Personally I loathe them - a great way to mush up the sound. Its the guy who pulls the trigger, not the gun. However, if there are less than about 15 sliders per channel, needed resolution will clearly not be there. I ugess I'm too used to 30 band boxes. Have you considered bass and treble controls ? Now, there are some blunt sticks! ;-) |

It's all digital, has two 31-band equalizers and multiband parametric equalizers, a visual display that can be driven by their microphone, plus other goodies.

But can it make coffee? ;-)
Seriously, after looking at the description it seems like a no-brainer for less than $250, but the lowest price I could find on the net was $318 for a new unit - could you tell me where I can get one for less than $250? Though it still looks like a great deal at $318, my original idea was to pick up a cheap used equalizer on ebay for under $100. As the price of the new "toy" keeps going up, the less appealing the "toy". Another issue with the DEQ-2496 is the serious overkill - it would be nice to have all the features available but how many will I actually use and how much of a learning curve will there be? I will definitely consider it, especially if I can get it at the price you mentioned. Thanks for the suggestion, John "Stu R" wrote in message m...
