dynamic EQ feature in what A/V receivers?
Hello,
I am looking for receivers that have the Audissey Dynamic EQ feature, Denon AVR-1709 has it, do you know any other A/V amplifiers that have it? DO the other brand of A/V amplifiers have similar feature? what is it called? Its a feature that at low level volume: ( in order not to disturb neighbours ) http://www.audyssey.com/technology/dynamicEQ.html Have any of you used this feature? its good? thanks Mario |

Denon, Onkyo, Integra have it but the best info is at the Audyssey website. DO the other brand of A/V amplifiers have similar feature? what is it called?

I've heard it but I don't use it. Kal |

Have any of you used this feature? its good? They have another feature called MultEq which supposedly corrects for room acoustics. My studies* to date have led me to believe that there is no decent electronic solution to the problem of room acoustics that has been discovered, and that any product which claims to be that solution is bogus. I'd hesitate to put much faith in a feature designed by the same company that touts MultEq. *Frequency response varies based on location in the room. If you use EQ to flatten frequency response at one point in a room, you make it worse in most other points, and you can also add phase distortion to the signal due to the EQ filters. |

Spoken by someone unfamiliar with Audyssey MultEQ, as it is not simply an amplitude/frequency EQ. They acknowledge the points in your last paragraph but have solutions. (Yes, I know, no solutions, other than correct acoustical design and treatment, are perfect.) Kal |

(Yes, I know, no solutions, other than correct acoustical design and treatment, are perfect.) The problem is that everybody and his brother claims to have solutions... last year's AES show had a dozen or so companies with magic room equalization devices, from JBL, Genelec, and Equator down to Coneq and IK Multimedia, and the only thing they all had in common is that they all sounded bad. It's possible to fudge some low end problems in small rooms a little bit with EQ, and it's possible to fudge speaker problems that cause frequency response problems that are position-independant, but beyond that the physics just don't work. I don't ask for a system to be perfect, but in the case of most of the systems I have seen they sounded substantially worse with the magic box turned on. The exceptions were systems like the JBL which worked only below around 200 Hz and made only mild correction. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I'd hesitate to put much faith in a feature designed by the same company that touts MultEq. The problem of what speakers sound like in a room has several aspects, some of which can be addressed with electronic equalization, and some of which cannot. The big, big issue that can't be addressed very well by electronic means relates to slap echoes and standing waves. Those are best addressed by room design and/or room treatments. *Frequency response varies based on location in the room. True, but there are also overall trends. For example, if you put a bookshelf speaker in a corner, there will be a build up in the bass region due to the corner's effects on the speaker. The room will tend to be bass-heavy all over. If a speaker is designed for a very large room, it will be bass-heavy in a small room. If a speaker is designed for reverberant rooms, it might have a dip or a peak in a crossover region in a dead room, or vice-versa. Some speakers can be a little light on the bass end, but take well to electronic equalization. A speaker may be voiced for use in a very dead room, and then be overly bright everywhere in a live room. If you use EQ to flatten frequency response at one point in a room, you make it worse in most other points, Please see former comments about overall trends. and you can also add phase distortion to the signal due to the EQ filters. Pretty much a "fear of the dark" issue. Phase response in most of the room is soup. Its so bad it can hardly be hurt. |

Did you look on the Audyssey website? http://www.audyssey.com/products/index.html -- -S I know that most men, including those at ease with problems of the greatest complexity, can seldom accept the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have proudly taught to others, and which they have woven, thread by thread, into the fabrics of their life -- Leo Tolstoy |
