That's starting to sound more and more like the Bose 901 system with its active equalizer... Little different approach, the Bose uses the equalizer to make the system itself have something approaching a flat freq response, it is designed to compensate for the fact that 9 small drivers don't have much low or high frequency response. The DSP in the B&O measures the rooms effect on freq response, particularly the bass where standing waves and such are pronounced, and compensated for the room. Back when Bose introduced the 901 there was no way to do the latter, the technology didn't really exist to do it. No more than the words of a goddamned B&O shill. A saw ZERO science in these claims. My ****ing sub-woofer has its own gain adjustment, I do not need some third party reflection analysis done by questionable engineering setups on a questionable DSP process screwing with my pristine feed. Take an acoustical reading of the bass frequencies at your listening seat some day, you'll see just now 'pristine' your feed is, moron. Just because *you're* ignorant of the science behind digital room correction, doesn't mean there isn't any. Hint: B&O is far from the only manufacturer using it. -- -S A wise man, therefore, proportions his belief to the evidence. -- David Hume, "On Miracles" (1748) |

Room correction DSP has been around in various forms at the consumer level for several years how. If you had a clue you'd know that, and you'd know what I wrote is true. You could have read about it in JAES articles, or even this popular source: http://en.wikipedia.org/wiki/Digital_room_correction It also doesn't really work all that well because it's trying to fix a time-domain problem with a frequency-domain solution. It can compensate for some bass problems, but it can't effectively deal with room problems over a wide area because the response is different from one location to another. In the case of the treble, the response may change totally when you move an inch. In the case of the lowest couple octaves, you have enough room to work that you can actually flatten the low band response in the sweet spot. Problem is that you can only remove peaks in the sweet spot, you can't really do anything much about dips. And of course anything you do to improve response in the sweet spot makes everything outside of it even worse. At the last AES show, everybody and their brother were showing off some sort of automated room tuning box, and for the most part they did more harm than good. Some of the demos were so nasty-sounding I could hardly stay in the room. But you're an ignorant, sputtering rantbox, so this is all new to you. I am not sure myself how this bizarre thread came to be crossposted to rec.audio.pro, but I would really appreciate if it ceases to be. --scott -- "C'est un Nagra.

It can compensate for some bass problems, but it can't effectively deal with room problems over a wide area because the response is different from one location to another. Actually it can work subjectively pretty well over multiple locations, depending on how it's implemented...Audyssey being among the best. And for the 'audiophile', where one one sweet spot needs to be 'corrected, they can work very well indeed. And the fact is they *are* aimed at correcting aberrations introduced by the room..which the ranter claims is 'total bull****'. In the case of the treble, the response may change totally when you move an inch. In the case of the lowest couple octaves, you have enough room to work that you can actually flatten the low band response in the sweet spot. Indeed, and this is what the B&O speakers focus on doing. Problem is that you can only remove peaks in the sweet spot, you can't really do anything much about dips. And of course anything you do to improve response in the sweet spot makes everything outside of it even worse. Which is one reason why some devices let you save multuple settings...one for 'sweet spot' and others for 'wide area'. For dips, physical room treatment is required. But treating peaks is better then NOTHING. At the last AES show, everybody and their brother were showing off some sort of automated room tuning box, and for the most part they did more harm than good. Some of the demos were so nasty-sounding I could hardly stay in the room. I'm never much impressed by anecdotal evidence, sorry. My own anecdote is that I've found that to be true in rooms that had no correction/treament whatsover, and I've also found notable improvement from room correction DSPs. Your mileage may vary. I dont' expect you to be impressed by mine. But either way, room correction DSP is far from 'total bull****'. There's good science and engineering behind it. And it's getting better all the time, as the engines get more powerful. But you're an ignorant, sputtering rantbox, so this is all new to you. I am not sure myself how this bizarre thread came to be crossposted to rec.audio.pro, but I would really appreciate if it ceases to be. Responding to it from r.a.p. is not the way to make that happen, then. -- -S A wise man, therefore, proportions his belief to the evidence. -- David Hume, "On Miracles" (1748) |

They'll also try and sell you special digital interconnects for this that have all the electrons aligned precisely so as not to interfere with the digital signal bits. ![]() The problem is getting the power to the speakers. Power over Ethernet is not up to delivering the amount of energy required, so each speaker would require a discrete [mains] PSU - not very elegant. |

No, they use DIN connectors because they are a European company, and for the same reasons companies like Tandberg and Revox and Armstrong and Naim use them, they are the standard in Europe, and they allow for a compact, single connector/single wire bundle approach. They have many advantages over the traditional US RCA connector, and the US is not the primary market for any of the aforementioned companies.

Power over Ethernet is not up to delivering the amount of energy required, so each speaker would require a discrete [mains] PSU - not very elegant. You may not think it's "elegant" but it's the way all self powered, active loudspeakers are implemented, power supplies at each speaker with a "mains" plug. Fortunately there are engineers who aren't as prejudiced with respect to design constraints. The only thing you need to get to the speakers is the signal, by IR, WiFi, BlueTooth, Cat5, whatever. It's a lot easier to send line level signals over long distances without degradation than it is higher power signals, the interface has higher impedance and is a known, stable, and unvarying as opposed to the impedance fluctuations you see at the speaker terminal of most any loudspeaker. |

But Britain's in Europe, and I haven't seen a DIN plug on any new equipment (except for MIDI) for 20 years. |
