Home Entertainment Guide BDP-LX71 for More Than 70 Years Our Standard Has Been to Reproduce a Sound That Comes Strikingly Close to the Original
Home Entertainment Guide BDP-LX71 For more than 70 years our standard has been to reproduce a sound that comes strikingly close to the original. Pure, clear, undistorted and complete in all its fine details. From the evocative power of the human voice in song, the fine nuances of a masterfully played violin or the driving dynamics of a rock band to the rich soundscapes, music and sound effects of movies. From the finest detail of today’s high definition video formats to colours of striking vibrancy and purity. We are dedicated to bringing all this right into your home, and giving you an immersive experience you never imagined possible. Whether on Blu-ray Disc, DVD or Super Audio CD, on CD, MP3 player or USB stick. To achieve this, we employ today’s most effective solutions: selected digital technologies that enable us to come closer than ever to the results intended by the artists, performers and directors. At Pioneer, we don’t just develop and manufacture products. We create digital performing artists, who promise you a unique experience that’s true to the original.

Lynn Olson: a Tiny History of High Fidelity
A Tiny History of High Fidelity, Part 1 A Rainy Night in Portland, 1936. Thanks to the restoration movement, much of downtown Portland still looks like this. Where do I come from? Where am I going? Who am I? These ancient questions are with us still. With only the slightest of changes, they can be recast into a form that provides a guidepost to the music lover, the audiophile, the hobbyist, and the artisan-engineer. Where does the art of sound reproduction come from? Where is it going? What do I seek from this art? Radio! 1900-1930 In the first years of Electrical Amplification, engineers had their hands full just trying to master the complex and non-intuitive mathematics of vacuum tube amplifiers and oscillators. It is worth keeping in mind that vacuum tubes were electronics in the first half of the Twentieth Century; before Lee DeForest modified Edison's light-bulb, the only form of "amplification" were relays that could repeat and rebuild telegraph signals. Radio relied on tuned circuits, massive brute-force spark-gap transmitters, large long-wave antennas, and crystal-diode rectification that directly powered the headphones. The faint signal that wiggled the headset diaphragm was a infinitesimal fraction of the megawatts that poured in all directions from the transmitter. Records, of course, were purely mechanical and acoustic, and wouldn't work at all if it weren't for horn-gain in recording and playback. What we now think of as electronic engineering back then was electrical engineering, focussed on keeping AC power transmission systems in phase and specialized techniques for pushing a telephone-audio signal down hundreds of miles of wire without benefit of amplification. -

High-Fidelity Speakers UTOPIA III PREMIUM EVO Ultimate acoustics 4-way floorstanding loudspeaker Grande Utopia EM integrates the Utopia III Evo line, with its legendary technological heritage. This exceptional high-fidelity loudspeaker boasts the latest exclusive innovations from Focal, and remains the ultimate choice... The sound architecture of Utopia III has been preserved, to reduce harmonic distortion in the fragile mid-range register, which is so very crucial for revealing the artist’s emotions. Both loudspeakers are equipped with the very latest Focal innovations: the NIC (Neutral Inductance Circuit) and the TMD suspension. The entire crossover system on the new speaker drivers has been redesigned. The rigidity of the Grande Utopia EM Evo cabinet has been improved using reinforcement rings positioned around the speaker drivers. The best components of their generation have also found their way into the line: cables manufactured in France, a denser acoustic material inside the subwoofer, and the double terminal boards. -
Three Bookshelf Loudspeaker
Three Bookshelf Loudspeaker Classic Series The NHT Classic Three is the best bookshelf we’ve ever built and we’ve built quite a few over the last 22 years. The Three offers great bass response (close to 40Hz in room), plus wide-open, natural sounding mids and highs. While it’s a really good speaker for home theater, the Three is simply remarkable for music playback. Stereophile Magazine’s Robert J. Reina said “...the Classic Three is a superb value, par- ticularly for those listening rooms in which size and cosmetics are important but whose owners are reluctant to give up performance in bass definition and extension and in high-level dynamics.” Soundstage’s Sid Voola said “...in some ways, I would be hard-pressed to discern the Classic Three’s performance from that of a similarly priced small floorstander. Add in the outstanding imaging and soundstaging capabilities and the Classic Three becomes a very compelling value, clearly matching or exceeding the performance of other bookshelf de- signs. The overall neutrality and rich midrange reproduction enhance this value further and lead me to conclude that the NHT magic has been preserved -- and then some -- in the Classic Three.” The Perfect Vision’s (AVguide.com) Chris Martens said: “As I see it, whether listeners are spending $800 or $80,000 on a new pair of loudspeakers, they want the same thing— namely, to get as close as possible to the heart and soul of the music. No other afford- able bookshelf speaker I’ve heard does a better job of that than NHT’s Classic Threes”. -
Sigma DSP for Active Speaker Systems ‐ Application Note Brewster Lamacchia 19‐Aug‐16 Momentum Data Systems
Sigma DSP for active speaker systems ‐ application note Brewster LaMacchia 19‐Aug‐16 Momentum Data Systems http://www.mds.com Introduction The availability of low cost, efficient, high performance class D amplifier devices in the past few years has enabled the use of in‐speaker electronics for better performance in not just subwoofers but also in primary channels of consumer oriented audio components. The availability of A/D and D/A devices with enough dynamic range for high performance home audio has also been a key component in an active (powered) speaker design that uses DSP. While powered PA speakers for “Pro” audio have been available for a number of years, those systems typically lacked sophisticated signal processing and had limited performance parameters. Passive crossovers can be replaced with DSP based filters that allow optimal matching of woofer and tweeters (2‐ way systems) or more complex multi‐band drivers. With increased DSP processing not only can filters be implemented, but extra equalization to flatten the system response (or tune it for a specific sound characteristic) can be performed. That same DSP device can also be used to implement features that protect the drivers from damage due to thermal (overheating) effects of high power levels, as well as prevent hard clipping of the amplifier and/or excessive driver excursion, which have very audible side effects (increased distortion and heating for the former, and popping noise and/or mechanical failure for the latter). MDS has developed hardware platforms for in speaker electronics based on Analog Device’s Sigma DSP. The Sigma DSP integrates a number of useful peripherals and has a very simple and low cost power supply design. -

ULS-15 Subwoofer & HB-1 Mk 2 Speaker
Hsu Research ULS-15 Subwoofer & HB-1 Mk 2 Speaker Gene Pitts UNDER THE “NORMAL operating conditions” prevail- league as car prices. Too rich for my blood or rather my ing in my 13x33-foot listening room, I don’t make a bank account. While I can usually hear the difference permanent change in my reference loudspeaker system achieved by a system with a five-digit price over one very often, however frequently I might drag some with only four numbers to the left of the decimal, if intriguing speaker in for a listening trial. First of all, I am there is one, I’d rather put those dollars into the music, too much of a cheapskate, and the really good systems i.e. the LPs, the tapes, the CDs, and now the downloads ordinarily cost out to dollar totals that are in the same and computer memory banks for tune storage. I have the audiophile voice frequently quipped that the music is more important than the gear and that I can always tell the difference between Bruce Springsteen and Barbra Streisand. However, I am not too arrogant to admit that sometimes two different speaker designs will sound enough alike for me to confuse them if I am not listening closely. This is particularly true if they have been level matched at perhaps 3 kHz and here I do not mean equalized over a broad band. The other main reason I don’t change speaker systems often is that the good ones are big and heavy and I am too lazy and weak to deal with such dif- ficulties if I can think of some sneaky way to get a better result. -
