Sound of fever: energy

Audio fever
??????????????????Of: energy
????????????????? Original starting in 2008-11-17?? Popularity: 26019

sound here is not interested in a fever or do not understand, do not read, because maybe you will probably find boring. No meaning.
However, in order to tastes, there is little detail as possible generation. Friends within the line, do not too long-winded article.

audio equipment is a voice device. Fever is usually referred to their illness. But the fever audio is not \For example: audio equipment usually requires a power output of 10W is enough, to have chosen to do their 100W; Another example: spend 100 dollars to make a sound device to release \enough, however, have chosen to spend on this basis, 200, the \More fever will add 500 on this basis,[link widoczny dla zalogowanych], calling for \For the sound became muddled fever requires: the same \... ... They each note in order to seek accurate and bright, has at all costs. They do not take into account the energy and the audio equipment is also the proportion of their inputs, only blind pursuit of perfect sound quality stereo fever. This is the sound of fever.
in the audio, the sound like a fever, the fever came together like a fever group. The title of fever each other enthusiasts. They do sound out of the device to a fever.
However, these are just a fever above the level or intermediate. Really high-energy enthusiasts are often very particular about sound quality. Their behavior is also very crazy.

enthusiasts roughly divided into three categories, although they act very different, but the fans have a good ear. High level of the gold ears title. Where:
welding school: their own hands to build equipment. The circuit must know, understand acoustics, and have enough ability. What these groups in the enthusiast level of both. About entry-level to carry out some soil Own Mic; senior has foothold in the world and unambiguous.
purchase school: they proficient with a variety of equipment, which is generally difficult to master. They are proficient in acoustics, pay attention to the complementary quality, with excellent equipment, and financial strength.
nobility to listen to local school: These are often very rich, they often do not understand audio equipment, but ignored the audio equipment required is very high. The principles of their election equipment is: do not consider the equipment with only select the most expensive. Monument or spend lots of money hiring the best fans to help achieve their aspirations. Always wanted to work the equipment as high as their first-class. But they spent 10 million yuan a set of audio playback equipment, the purchase sent to spend 100 million to spend 20 million in basic welding school can achieve the same effect. Fortunately, listening, and do not care about the money sent.
I is an audio equipment enthusiast. Hands of their own kind. Something like his own design manufacturing, those who can do their own, generally physical line. Find yourself ample food and clothing, and fun-filled.
sharp decline in the unit cost, to the later, the company in addition to the two managers and I, the rest can not get even the wages. Ultimately, all home managers simply let Everybody fend. Advantage of this opportunity, I took a job in Zhongguancun, South Korea and Taiwan to the design of the products they need. Although very hard, can not imprisoned. Monthly salary is not bad. Not only income was ten times the original unit, but also a lot of time can be disposed of. This is the sound of fever, the to the I great financial support. I sound this time is in the era of development began to prevail.
With these, you can I made the original soil Own Mic to a big change, determination Yat Ming scared. Although still soil Own Mic, but the great emperor Hanako a sudden change from begging the same feeling of Emperor Ming.

determined to their own devices in large-for-all, the device is relatively easy to mix. In general, all from the back step by step according to their own listening preferences. First select the speaker; then select the speaker line; then select the power amplifier; then select the level before the signal line; final choice of preamp.

one. It-yourself design and manufacturing
the bass speaker unit is the Swans top-level speakers F8 (a pair of speakers more than 1,[link widoczny dla zalogowanych],000 of the money only, not expensive); tweeter diaphragm is HuiWei top belt R2, fast frequency response . Divider design of their choice, do it yourself.
surprise since we Yat Ming, their traditional speaker design is not only the impact of routine and restraints, seen the world nearly a thousand speakers of the design section, and the gathering around the world house long, and then design according to their preferences about hundreds of models speakers. After re-screening, the design of the selected sample 8 processing Love. And then improve them, and then lyrics. Finally determined.
fact that the new speaker box design prototype theory than the volume (23 liters) is much greater, this wall has inside and outside speaker three. Around the innermost wall design theory is the volume of space; others are anti-resonant space, anti in the structure and occupied a separate sound-absorbing material. Speaker of the inner wall has many holes. Irregular arrangement of their inclination is to prevent internally generated low-frequency speaker in radio (the meaning of some bold theory); design of the middle layer of the cavity structure, the internal speaker sound of main harmonic reducing shock (preparation of more than 300 small Hai Muhuo hereby cavity), the outermost layer is what we see. This speaker design is complicated enough, right? Or a fever?
friends of expert speakers generally able to guess what it is a structure. When designing the number of speakers also master of foreign material from this speaker design bass Lang get some inspiration (but it is still the Helmholtz resonance, but should be \Helmholtz resonator with a totally different). The Helmholtz resonance theory is not so good applications, in addition to the bass speaker cone vibrating mass or weight, the stiffness coefficient of cone, cone diameter, the first and second cavity volume ratio of choice, but also and the speaker structure is closely related to specific materials. Especially the latter, this requires a lot of time and money, to span the actual situation, in any case be found. Therefore the speaker is to selectively build a prudent use of the Helmholtz theory of acoustic resonance. The speaker uses the overall acoustic resonance of Helmholtz theory, the low-frequency speaker big downward. As incredible as sparrows give birth to a goose! It greatly exceeded those of the classic speaker fame to the low-frequency limit of physical acoustics. According to I check the website, currently in the world, using the same specifications of the speaker, the appearance of the same size, has not a special low-frequency speakers can be compared with the I's, and are far less. Just know that eight-inch woofer, 23-liter effective volume, can release 20Hz (-3dB) frequency is not distorted, definitely would stare knot. I own of course, is overjoyed.
I second layer spatial structure of the speaker a good solution to the Helmholtz acoustic resonator for material defects. Well attached to prevent the undesirable low-frequency resonant dive to stop a low-frequency stretching and hysteresis. The actual situation shows that: The following audio clean and pure in 80Hz. The speaker design is very good.
speakers are floor standing. Outermost wall to prevent bursting in the speaker vibration generated when the moment, the internal speaker is also set to strengthen the three bulkhead. Inside and outside the three-way speaker, the next five, greatly enhance the stiffness and strength of the speaker. Surface will not put a truck speaker distortion.
speakers make is entirely their own hands, do not trust a professional manufacturer of manufacturing. The speakers use MDF for a total of 102 large and small (some very complex parts.) Now the company has no classes, Jiu use of the company's milling process them out piece by piece, cumbersome and troublesome. Then do the bonding fixture, to 102 boards a little bit careful bonding together. Finally, install the speakers and crossover polished paint.

II. The choice of speaker wire
speaker unit used in all the Swans products, they feature speakers, accurate. However, less mellow sound. So are the speakers voice. Speaker wire should be chosen so mellow type. I passed the double comparison, select the Fan Denghao speaker wire. Five two-meter-long wire 3600 silver buttoned bid was okay. Listen to, it does change the speaker made a little wood defects.

III. Super PA speaker box
sound quality not as sweet, so paired with a tube amplifier. Manufacture of the equipment I really really a fever. Almost at all costs.
I remember the biggest ever single tube power amplifier is designed for the U.S. company Western Electric design and manufacture of sports venues. They use 8 production 6L6G-GT to the U.S. B output amplifier tube, rated power 240W, maximum power 300W. I want to make their own side of a power rating 500W, 800W maximum power amplifier, to overtake the United States. This requires a more powerful tube. However, the source tube was very difficult, plus the computer network was also developed, could not find I need to power products. To find out no results.
After much deliberation, I finally remember that when the side of the Ussuri River in the Great Northern Wilderness and Construction Corps, when he saw the river opposite a former Soviet radar station, then strained Sino-Soviet border armed conflicts, where the Soviet and from the very trouble. At that time we have several good friends also rode on a dark and stormy to swim across the river to house ducks raised under the Soviet eggs. Attached to it several times have not been found. Now Sino-Soviet relations had thawed, Riverbanks has long been open trade. I do not know that the radar station is still not in? Thought of this, I excited, immediately contact the comrades still remain there, tell him I want to do, and then wait for him messages. Did not take long to receive the other letter: that the radar still has not been for many years. Swim across the Ussuri River a few days before his comrades, take stone smashed into several pieces of glass radar station, which is really something. He came back to take the telescope a few days, did not go, of course, there is no discovery.
\high-power tube station.
The Great Northern Wilderness trip I was a rewarding experience, hold back a box of tubes.

amplifier tube amp make more trouble, here on behalf of the more clearly it is not easy. I would not describe friends.
This amplifier uses the 2 × 8 annual output of the former Soviet Union 60 (equivalent to producing 845) B power tube output.
output transformer output transformer dedicated people in Taiwan - \The hexagonal cross section 8N use of oxygen-free copper enameled wire, and the secret system of different density and direction of magnetic transformer core system with a combination of stack, plus home-made high-frequency wax casting, low loss, excellent dynamics,[link widoczny dla zalogowanych], frequency response extremely wide, the sound quality is excellent. These unique offerings made his audio transformer Cheats brand in the international community magpie cries of fever, firmly standing in the forefront of the world's audio transformers. I was such a transformer for the custom really took a lot of energy, spent most of the silver.
mix of hard and debugging through the power amplifier distortion is not less than 2 × 500W. After testing, the signal to noise ratio to 98dB; dynamic to 103dB; distortion (20? 20000Hz) is less than 0.4%,, 1000Hz when the distortion is less than 0.07%. Split

tube preamp with the former Soviet MiG-25 aircraft using high-fidelity tube 6922, Kurt Wimmer high-speed capacitors, the United States Western Electric produced no bleaching, no sense of resistance , Switzerland, the volume of the potentiometer; signal line all use relatively soft beauty \

10 split tube power level U.S. 5R4WGY antique parallel rectifier; filter capacitor to all the luxury no sense to use the U.S. veteran Sibi capacitor (12 47 dollars per capacitor) ; multiple giant British built classic drop of liquid from the circulation of large D card choke (5 chokes per 195 pounds) ... ... there is only 50 kg of the transformer! Internal power supply including transformer included, lead to all levels of oxygen-free copper with silver plated wire 4N.
power reserve due to a power stronger, at full load,[link widoczny dla zalogowanych], the supply can meet the continuous super Congrong 110 dB dynamic output amplifier; and full power output (750V voltage) case, the pattern coefficient is less than 1mV (generally shown device can not see the power of action). The purity of the DC power output current of the battery is almost the same. All the military than the current (including missiles and aircraft) equipment,[link widoczny dla zalogowanych], professional audio, and other power supply is much better.

I learned from the East Sichuan Daxian Network has a food enthusiast with a pair of giant speakers. 1200W power rating of up to two meters of its single speaker, the bass unit with four 30-inch De Weisha through professional speaker redundancy fever; 8 De Weisha through midrange driver and the 8 ball top tweeter breakdown Dan Maidan on both sides, it is truly powerful. The total sensitivity of 118dB! Terrible sound quality.
118dB sensitivity speakers you know the concept? Voice of the efficiency of its ordinary speakers of the two times in a fever! In a room of 100 square meters, with MP3 headphone jack of the power output is directly connected to the speakers, the sound of it, you can cover all the loud noise and indoor!
Even so speakers not to resist: its own set of hand audio equipment, had to be found all over the world looking for a pair of speakers to meet with them. He now has a pair of speakers so if together, we do not know how earth-shattering? I immediately contacted him,[link widoczny dla zalogowanych], the other is excited. I made a special trip to drive to an appointment to meet.
I Baan whole set of equipment packed a car trunk full to the brim, with a total weight of 300 kg.
(see \
ado, the same evening, the moment the two sides showed the guy. Wow! What a perfect pair of Big Mac!

the Sichuan fans have a British Masatoshi FMJ CD23T the CD drive. Price is not high, can the British authority \He usually listen to music using the CD drive directly 1V signal, plus an impedance converter, directly to the speakers (without any amplifier), sound very pretty. Just to listen to shed the feeling that some can not.
noisy with people incredibly excited, finally to determine: the source and the speaker to use his remaining devices all use the middle part of I's.

This is clearly a wealthy enthusiast, Sichuan. Specifically requested in their design and construction of villas next to a three-story building listening. Blocks east of the West. Into the south, internal lift, external staircase outside the secure channel. Entered into each layer, there is a lounge. In addition to locker room, the sofa table placed inside, wine cabinet refrigerator and articles. Noise inside the room through the heavy door (a door 150 kg), was his concert hall. The three friends are more than 100 square meters Office:
a ballroom floor. Triangular arrangement around the leather sofas along the wall, just north of there is a small raised stage, the top pressure pressure Ukraine lighting a large blocked off with a decorative plate. The middle is the gorgeous ballroom chandelier; sofa slip surface of the shell of a legal ceiling specified ceiling. Walls are copies of famous paintings, small stage, a Law School Herald Angel \Look closely to find the ballroom ceiling speakers are hidden behind the edge of the wall decoration. Inverting all building design acoustics. Swans EQ-10 woofer (in a treble unit is unknown.)
second floor is the AV room. The layout and equipment was much less than the layer. Office of the middle three rows of AV sofa; sofa in front of the projector on the DVD counter, next to a Pioneer DVD of this production and the \disdain in the eyes of fans (fans respected around the world: the British sound of the first place, followed by the United States following the sound, French sound, the sound of Denmark, Taiwan and the German acoustic sound. and even the Dutch are like the sound and the sound. The sound system Inside, each have their own special, not like the sound alone. This is mainly because the sound of commercial flavor too strong, too much flavor of digital sound, smell less, reluctant to spend money to get rid of this himself so hated the taste of those) . but these two devices are the top products, and are not used to listening to music, for the AV should still be acceptable. at least it's unique dynamics and surround effects.
AV room of the speakers also can: a full set of the German \Visit the music room. This room has no window. indoor floor, carpet, fabric sofa among a few. All of the walls and ceiling all use thin strips of wood arranged along the direction perpendicular to the sound of the varnish. look exquisite layout, However, comparing the taste of strong acoustic laboratory. Those thin strips of wood covered with sound-absorbing wood tip below; in the following tip muffler shop for acoustic resonance box of room. opened the sofa in front of two cotton curtain, a pile of audio equipment is impressively, about four pairs of speakers on both sides of breakdown. speakers across the back wall hung a carpet of a factory in Shandong Weihai, super-wide master Wang XX design process, \The tapestries, the brother did not expect to buy. a full 100 million of silver).
four pairs of speaker pair is cut the middle of Italy's new \speaker can handle without 40000. is a little outside the United States by JBL, I really do not like appearance, a bit old, is the main second-hand goods bought twenty thousand flowers, is said to sell the new fifteen thousand U.S. dollars. Beyond Daxian side of this trip is I want to be a Big Mac will be the speaker. The most outside Denmark's \I seduce Yueyue test, in the main agreement obtained, respectively, I connected the device, one by one some comparison.
Nautilus 805 sound quality when playing female and an excellent violinist. overtone violin soft female voice vividly rendered . only the sound field in the hall seemed more focused, small.
Italy plays the United States JBL speakers treble Pavarotti, \dynamic full, just and powerful effect that is simply bursting with earth-shattering! but slightly less sweet and soft.
say four pairs of speakers sound the best, non-\flavor. above the strengths of two speakers, she can be competent, without dragging mud belt. The only drawback is too much food she had. not seven, eighty watts of power to drive, she could not show vividly, as if even the Some of the sound is gone. In particular, to promote the use of transistors machine, this problem is particularly acute: \: two million below the level of transistor amplifiers do not deserve to promote the speaker. However, there is little within the tube amplifier and the power of 50W. It must be a good horse on the box with gold saddle. with the equipment I post, that old song put eyes light, rolling in the audio current to \\, who are all public Shaoyou one eyebrow micro-lock, the eyes do not know at what focal length (see what I do not know.) Tsai Chin has said that he was standing about 4 meters away; some said Tsai stations did not face him, and He is a departure from 15 degrees to 30 degrees, the Department of singing in this range when the shaking; also exclaimed: Tsai Chin-shaped singing sounds than their own ups and downs of equipment to larger, more realistic sound! thought she was singing Great shape never used it! even a slight movement of the foot Tsai, left foot or right foot, wearing a slope or a semi-soled shoes with heels, could hear it. ... ... you almost look Tsai used to sing in the ear! are seems to have forgotten is that the set of perfect match of audio equipment and forget how they are a perfect match! it is very accurate positioning of the sound field; very high degree of sound reduction; sound shape description of reality. Bi Yanjing listen, as if the speaker does not exist really can feel Tsai Chin was standing somewhere close to you as if you just walk out his hand to dance with them can pull Tsai Chin. but not where there stands a pair of speakers.
There is no doubt that the equipment connected to the two of us together is more than absolute Ya Zhong Ziqi met. bosom friend is hard to find, once again what a sympathetic acquaintance!
chopper a few hours after a small trial, we are still excited. have requested to open Large volume, high-power want to try it the dynamic power. but because of the power equipment and speakers are the Big [link widoczny dla zalogowanych], as long as the power knob to 11 o'clock, the whole building has changed a huge sound body, probably around the residents of a large not even think about quiet. To prevent nuisance to the public, the public Devil to, interested in the two speakers shipped to an abandoned coal mine train platforms.
the face of the cloud cover of fog around the stretch of verdant Daba, Open full volume, a beautiful \shaking of the ground shook!
near the huge paulownia leaves began to self-motivation was, trembling, they count on from the branch falls down! fluttering triumphantly, the rustling Sasa. What a \
radius around a radius of 50 meters range, rapidly rising gradually from near to far from descending the dust! these dark dust like a huge circular music scene, with the ups and downs of surging melody like the musical fountain, but entirely different ... ...
However, the great bright sound but smooth, soft, such as, without the slightest harsh and heart irritability. everyone's skull in the music when the sudden release of natural expansion, and then start rapid sublimation. seems to take the time space shuttle, and instantly came to a place. as if,[link widoczny dla zalogowanych], under the shady shadow of the moon, the Grand Canyon is at hand: that the howling of the breeze, and that the Qiuchong Qu Qu, and that flows unimpeded That aroma aroma of fire, and the sturdy Indian dance, Indian drums ... one by one to figure hovering at the original of. really Provisional its territory, that was so vast, so thick stupid, it's heavy, is so Bleak! Chujing life, I do not tear Yingkuang!
have heard the tenor of the beautiful melody, heard the high frequency harmonic sounds of nature. But the feeling of ultra-low frequency is rare to experience. powerful amplifier in the I impetus, giant issued a sturdy low frequency: the ear can hear part of the body they can feel more a part of the other low. This is the second sound. powerful very low frequency infrasound will be Indian by the shoulders relative to the sound, red well-developed muscles collision sound, bonfire jumping coerced the empty dance sound and the sound of their full body and not through our ears and our hearts passed, so that every one from within the heart are deeply shocked!
whole a CD is done and then immediately change to the giant sculpture. silence fell face that even a mosquito could be heard. using static, such as children, such as moving from rabbit no longer appropriate to describe the. Properly speaking, it should be static like a Wang Bi pit, moving like dragons dancing sky!
their eardrums at this moment seems to still be heard coming from the distant echo, their eyes seem to still be able to see it gradually blurred the scene, still in their hearts TV drama to surging sounds of nature unrestrained endless. there are no one to speak, but quietly, quietly standing, standing, pondering, pondering ... .... really as Guyun: \is still prevalent \ears to \I leave these devices. Driven to despair, I had four sons back to their door door-law married into their possessions. married the daughter of the size of the two. think about where they will be well care of, I followed all day than running around, back and forth is much easier. This is the only consolation.
Prior to departure,[link widoczny dla zalogowanych], relatives, handing me a bag, which has 30 million, be appointed it. I finally saw I Heart four sons before a tearful goodbye. I will miss them, and never misses!
