音響怎么煲機--煲機的秘訣

admin 2018-03-28 23:39:08 無損音樂交流 0℃
煲機有如打通奇經八脈  本刊間中都會收到不同讀者的來電詢問有關煲機的種種問題,例如器材是否都要煲?又如何煲才對?到底為什么要煲機?不經過煲機程序的器材是否不能發揮出十足水準?這些已經不是什么新鮮話題的疑問原來令到新近加入發燒行列的朋友仍然頗感迷惑,希望可以獲得較為圓滿的答案,而我留意身邊為數不少具有獎歷的音響發燒友原來都不大重視煲機,他們重視的焦點放在其它方面,卻原來,煲機乃達至靚聲的根源之一,很多人都知道新器材需要經過Run-In,如果只以政黨聆聽當然假以時日也能夠達到Run-In的效果,不過,有效率的煲機方法一方面可大大縮短Run-In時間令器材更快進入最佳狀態,另方面也可以更全面、平均地運動器材或喇叭的全頻,關于這點,可以解釋因何已經使用了一段頗長時間的器材明明應該已經煲夠了吧,但在經過煲機程序之后卻仍有明顯的改善,這便是因為最常聆聽的音樂其頻率大多未能涵蓋由超高至超低的每一段頻率,即使有,播放的次數及時間亦難平均,所以站在煲機的角度而言是未竟全功,另外還有一個情況是久未使用或最近甚少使用的器材均可以透過煲機令其盡快回復狀態,以人為比喻,經過一定的身體鍛煉以后,再經常運動保持身體在最佳狀態,自然工作效率也會大大提高吧,因此,掌握正確的煲機方法實際上對玩HIFI的得益相當大。煲機三部曲  要進行煲機首要者是選擇合適的軟件,這主要可分成兩類,首階段煲機應用第一類訊號碟進行,訊號碟記錄的Pink Noise最重要是頻率夠齊全,由20HZ至到20KHZ具備,連續地由最高而至最低不斷播放,這類訊號碟并不難找到,雨果金碟1、Stereophile Test CD 及部份測試碟都具備,而Sheffield Lab所出的舊版XLO測試碟其中第8段更為煲機訊號中的經典作,其一段訊號中交錯包含了各段頻率,雖然開大聲時相當吵耳難聽,但煲機的效果卻相當理想,只可惜此碟經已停版,讀者唯有向身邊的朋友打聽相借回來使用吧。踏入第二階段的第二類碟乃用頻寬兼顧較全面的音樂碟進行煲機,首階段是開通全頻,次階段著重的是煲音樂感。選擇的CD碟可以考慮Unplug2或3,Unplug2中兩段寶森多夫演奏用鋼琴錄音及三段古典名琴片段便十分\'正斗\',用以煲機的確一流,而碟中還有教導不同樂迷著重古典或爵士樂等的不同煲法;Unplug3的煲機片段亦屬上選,而且既是測試片段也可作為煲機(Track 11-20)的音樂,不會令人煩厭。接著讀者也可自行進入第三階段的煲機,乃以自己最喜愛的音樂軟件類型進行,使器材在播放此類型的音樂時更能發揮盡致。  當預備好合適的CD后,煲機程序便可以展開,先以煲齊系統的所有器材計算,在放入CD碟后 program 所要重覆播放的片段,然后按Repeat不斷重播,前級音量掣調節到平常的聆聽位置,不過大亦不宜過小,過小便煲不到喇叭的低音單元,而為安全計,可先行聽聽最高及最低頻段時喇叭有否不勝負荷的情況,播放用的訊號碟聲音基本上不作欣賞用途,多聽會令人感到心煩甚至頭痛,因此用其煲機的初階只適宜在離家外出、家中沒有人時進行,一般而言便會是你的上班時間,這樣每天大約可進行十小時的煲機,要進行時有些要點是要留意的,一是使用膽后級的話便不宜離家外出進行煲機,瞻開著了在安全性、穩定性始終不如原子粒,安全第一,還是不要冒險,要煲的話,用其它原子粒后級好了,又或者只用不會令人煩厭的音樂碟待有人在家中的時候才煲;其次是噪音問題,可能會引起鄰居的不滿或投訴,解決的方法是將左、右兩只喇叭以面貼面方式的相位相反,活動動作變成一只向出時另一只卻向入,面對面便會抵消了大部分的聲音,換句話說噪音會大大降低而單元活動幅度卻仍然有同接正相時一般大。不過,假如在將喇叭面對面時噪間仍覺得擾人又如何解決呢?特別是大喇叭高音特別響亮,解決的方法有二,十分簡單,可用咭紙卷成圓筒狀(或索性用衛生紙筒裁短),放在兩只喇叭的高音單元之間,再將喇叭推貼令紙筒位置固定,吵耳的高音便會減少了,至于兩只喇叭面貼面的距離可移近至兩、三寸,越近越能夠抵消聲音。另一個方法是用棉被之類覆蓋在喇叭之上便可以蓋掩噪音了,但要視乎情況留下疏氣空間,以防萬一音量調得太大時長時間下來單元溫度會上升,預留空隙可讓其有需要時疏氣散熱也。功夫、耐性換靚聲  那使用訊號碟煲機一般需時多久呢?其實可以自行每隔兩、三天便比較一次以 解進度,通常在進行了最初的一、二十小時之后已經可以聽到分別,至于要多久才足夠可以視乎自己的條件及耐性,一般初階以訊號碟三百小時已經十分理想,然后再以音樂碟煲一百小時左右,這數百小時的時間一般乃指需時較久的全新開箱喇叭而言,其它CD機、前、后級需時較短,線材也不用太花時間,總言之是視乎耐性吧,硬要規定多久容易令人心灰,難以堅持,反正短短數天的煲煉也可以見功,多煲一點得益便會越大,對于久未使用或少用的器材也可相應以短時間的煲煉使回復狀態。  那么在煲機以后的分別會在那方面呢?我想讀者們也必心里有數,可以預計得到吧!不錯,便是高、低頻去得更盡,聲音更從容暢順,弱音部分分外清晰、精細,而低頻輕易下潛得得更低、量感也更為豐滿等。煲前與煲熟后的分別一句形容便是\'開了聲\'進入了狀態,對從未進行煲機程序的朋友的確值得留意如何正確地選擇軟件去嘗試及體會一下煲機所帶來的音效改善,不過受到家人或其它條件所限制的人士只好另想辦法,或許可將音量妥協地調低一點或造好隔噪音的功夫才煲機吧!  還想補充一點有關煲機的問題,只單一件器材煲煉會比較容易,如果只煲CD機最方便不過,只要按Repeat由它唱個七日七夜不關機也沒有問題;而CD機至前級的訊號線也會一同煲,前級扭開正常音量則前級也可煲煉,而前去后級訊號線、后級、喇叭線在不接喇叭的情況下仍可以連接燈瞻或自砌電阻來煲,最重要是有Loading便成,喇叭要煲便無可避免要開聲了,其造成的噪音問題會是煲機過程中最令人困擾的事情,宜小心處理,勿因此機時惹起與家人或鄰居因此而爭執,而熱量高的后級也要留意散熱是否足夠,否則長時間工作令溫度上升會有引致危險的可能性,讀者若在進行煲機期間務須注意安全問題,特別是在離家外出的情況下去煲機,也再一次提醒各位瞻后級不宜在無人看管下長時間開機,因為萬一市電供應有突然意外的變化便有可能會令燈膽出現不穩定的變化,后果難以估計,這情況就如同使用熱水爐或煲湯睇火般,不怕一萬,只怕萬一。較激烈的煲法  有一派資深的發燒友認為煲大喇叭時音量可以盡量調大,細喇叭則在最初的一百小時以正常音量,其后照樣加大音量,約比正常聆聽再加大一到兩格令訊號落至低頻時低音單元瀕臨拍邊邊沿而仍未拍邊為止。這樣煲喇叭在約十小時后單元旁邊及背后的接線柱位都會產生熱力,外部手感溫暖,內里則已發熱了。該派同道有感如此煲喇叭為最撤低、最有效及最快捷,正是各師各法,本人也嘗試過這種方法,喇叭在進行大音壓煲煉之后,起初聲音會很sharp,大概是高音放得很盡的緣故,在完全煲透以后便會一切聲音肯定是去得最盡,但這種煲機法需要對HIFI具有較深入的認識,一不小心留神容易對單元、分音器做成傷害,要認真考慮是否要冒險去獲取最、最撤底的煲煉效果?條件上又是否容許呢?因為即使將喇叭面對面一只接反相后噪音仍然會相當巨大及令人吵耳難耐,我只想告之讀者有這么一派一理論卻不建議各位奉行之,還是依照溫和的煲機程序去進行比較穩健,而成效上亦足夠令人滿意了。 Bao machine is like get through strange classics 8 arteries and veins between this print in a variety of questions that the incoming message that can get different reader asks concerned Bao chance, for example whether does equipment want Bao? How Bao just is opposite? Why to want Bao chance after all? Whether cannot the equipment that does not pass Bao engine order develop dye-in-the-wood standard? These are not what the doubt of fresh topic makes be joined recently so any more have a fever the friend of cavalcade still feels quite puzzle, the hope can achieve relatively satisfactory result, and I am advertent beside the sound that amount to has award one by one not less has a fever friend values Bao engine not quite so, the focus that they take seriously is put in other respect, original however, bao machine amounts to one of germ to beautiful tone therefore, a lot of people know new material needs to pass Run-In, if with political listen respectfully false of course the result that also can achieve Run-In with time, nevertheless, businesslike Bao chance method can shorten greatly on one hand your equipment enters Run-In time more quickly groove, other side also can move on average the complete frequency of equipment or horn, about this bit, because why had used a paragraph of quite long material,can explain obviously should already Bao became enough, but there still is clear improvement however after passing Bao engine order, because,this is most the music that Chang Ling hears its frequency fails to cover mostly come by freeboard exceed each paragraphs of low frequency, although have, the number that broadcast and time also difficult average, it is the angle that stands in Bao machine so not unexpectedly full result, still having a case additionally is long the material that was not used or uses very less recently all can make his reply as soon as possible through Bao machine condition, with factitious analogy, after taking exercise through certain body, often move again maintain the body to be in groove, natural work efficiency also can rise greatly, accordingly, master accurate Bao chance method to comparative to enjoying the benefit of HIFI actually big. The person that Bao machine trilogy should undertake Bao prow wants is the software with right choice, this basically can divide two kinds, head level Bao machine applies dish of mark of the first kind of question to undertake, the Pink Noise that question mark dish records is the heaviest if frequency is enough all ready, come to be had to 20KHZ by 20HZ, continuously by highest and broadcast ceaselessly to lowest, dish of mark of this kind of question is found not hard, dish of pluvial fruit gold 1, Stereophile Test CD and halfway test dish are had, and the old edition XLO that Sheffield Lab place gives checks plate among them the 8th paragraph more in mark of Bao machine question classical make, the crisscross in one of Duan Xun date included each paragraphs of frequency, although leave aloud when quite noisy side is offensive, but the effect of Bao machine is quite ideal however, regrettablly this dish classics already stopped edition, the reader asks to borrow to the friend beside only use. The 2nd kind of dish that steps the 2nd level uses the musical dish with frequency wide more comprehensive give attention to two or morethings to have Bao opportunity therefore, head level is to open complete frequency, what second phase emphasizes is Bao music feeling. The CD dish of the choice can consider Unplug2 or 3, senduofu performs two paragraphs of treasure in Unplug2 to reach part of 3 paragraphs of classic name musical instrument with piano recording very \' is fighting \' , machine of Bao of in order to is top-ranking really, and still have in dish teach different happy fan emphasize classic or jazz the different Bao law that wait; The Bao plane part of Unplug3 also is belonged to on anthology, and since test extract also can serve as Bao machine (Track 11-20) music, won't make a person irritated be disgusted with. Then the reader also can enter the Bao plane of the 3rd phase by oneself, therefore with oneself most the musical software kind that like undertakes, make equipment can be developed more when the music that broadcasts this type send. After the CD with very appropriate provision, bao engine order can spread out, calculate with all equipment of Bao neat system first, after putting CD dish Program place wants to weigh the extract that Fu broadcasts, press Repeat ceaseless rebroadcast next, class volume pull adjusts before common listen respectfully position, also should not be too small greatly nevertheless, cross pee Bao to be less than the bass unit of the horn, and it is safety plan, but go ahead of the rest listens highest reach lowermost frequency Duan Shila to have deny lose the case of carry on one's shoulder deeply, broadcast voice of used question mark dish to basically do not make appreciation use, listen more can make a person feel be perturbed has a headache even, use its Bao machine accordingly first rank be in aptly only leave home go out, when there is a person in the home, undertake, generally speaking can be your time going to work, can have the 10 Bao opportunity of the hour about everyday so, when wanting to undertake, some points are to want advertent, the word that is the class after use bravery shoulds not be leave home go out have Bao opportunity, look up was leaving to be inferior to atomic bead from beginning to end in security, stability, safety first, still do not want adventure, want the word of Bao, the step after using other former bean is good, perhaps use only again won't make a person irritated when the musical dish of be disgusted with waits for somebody to be in the home ability Bao; It is noise problem next, may cause the dissatisfaction of neighbour or complain, settlement method is will left, right what two horns stick range pattern with the face is phasic and contrary, mobile movements becomes to when going out another however to into, can offset face-to-face major voice, in other words when noise can be reduced greatly and mobile extent still has unit to receive positive together however general big. Nevertheless, if be in the horn face-to-face when how to still feel faze person is solved again between a confusion of voices? Especially big horn is high and special resonant, settlement method has 2, very simple, shape of cylinder of roll into of usable Ji paper (or cut into parts with bumf canister simply short) , put between the high unit of two horns, push the horn again stick position of your paper tube to secure, noisy of ear high can decrease, the distance that sticks a face as to two horns face can move to come nearly two, 3 inches, can support noise elimination tone more nearly more. Another method is to use quilt and so on to enclothe can build noise of attack by surprise on the horn, but should inspect the circumstance leaves scanty air space, be ready for any eventuality when volume is moved too greatly come down for long unit temperature can rise, when obligate space can let his have need, scanty gas comes loose hot also. When kongfu, endurance changes beautiful tone to use machine of Bao of question mark dish to need commonly then how long? Actually can proper motion every other two, compare 3 days in order to see plan, undertaking normally original one, can have heard after 20 hours respectively, as to should how long ability is enough and OK inspect oneself condition and endurance, general first rank with question mark dish 300 hours already very ideal, next again with musical dish Bao 100 hours are controlled, time of these hundreds hours points to therefore commonly when needing longer brand-new horn opening box, other CD machine, before, hind when class needs shorter, wire also need not too beautiful time, in sum is to inspect endurance, extortionary regulation makes popular feeling how long easily grey, hold to hard, anyway the Bao refine of short number day also can see result, a bit benefit of much Bao can be jumped over big, to long the material that was not used or uses less also can make reply with the Bao refine of short time accordingly condition. So in Bao machine the following can you be in respectively that respect? I think readers also need the know exactly about sth in the heart, can predict to get! Pretty good, it is tall, low frequency goes more all, easier free arranges sound, weak tone part especially clear, careful, and low frequency easily submergence must get lower, quantity to feel more plump also etc. Before Bao as ripe as Bao after respectively look of one sentence pattern is \' opened acoustical \' to enter state, go trying to reach the phonic effect improvement that experiences Bao machine place to bring to never undertaking the friend of Bao engine order is worth how to choose software correctly alertly really, be forced to think way additionally nevertheless by the personage of family or restriction of other condition institute, can move volume compromise ground probably a bit lower or had made the time that lies between noise ability Bao machine! Still think complement concerned the issue of Bao machine, only onefold an equipment Bao temper with fire will be lighter, if Bao CD machine is the most convenient nevertheless, should sing a 7 night of 7 day not to close by it by Repeat only machine also do not have a problem; And the question mark line of the class before CD opportunity comes also is met together Bao, it is normal that class is twisted before the class before volume criterion also but Bao refine, and before line of mark of question of the class after going, hind still can join below the case that line of class, horn is not accepting a horn lamp look up or come from resistor of build by laying bricks or stones Bao, the heaviest if Loading is become, the horn wants Bao to be not had can avoid to want voice, the noise problem that its create can be the issue that the person makes perplex most in Bao machine process, appropriate tread lightly, not because of the occasion when this machine and family or neighbour because of this conflict, and quantity of heat is high hind class also should come loose alertly heat is enough, work for long otherwise ascendant meeting has your temperature leave the possibility that incurs risk, if the reader is undertaking Wu must note safe problem during Bao machine, be in especially leave home the situation that go out continues Bao machine, the class after also reminding each look up again is unfavorable switch on the mobile phone for long below unmanned guard, because in case the variation that town report offers due and abrupt accident can make likely the change that lamp bravery appears to be not stabilized, consequence estimates hard, this circumstance looks askance as using hot water furnace or Bao boiling water like fire, do not be afraid of 10 thousand, be afraid of only in case. More intense Bao law has one to send elder to have a fever friend thinks the volume when Bao big horn can be moved as far as possible big, fine horn is in 100 original hours with normal volume, increase volume all the same ever since, increase the one bass when to two case your question mark falls to low frequency to unit is close to taking Bian Bian edge and still did not take a side again than normal listen respectfully about till. The wiring column that such Bao horns reach backside by the unit after about 10 hours metropolis generation heating power, exterior feel is warm, inside in calorific already. This clique is fellow have move is such Bao horn is most remove reach the lowly, most effectively the quickest, be each division each law, oneself also had tried this kind of method, after the horn is undertaking big news suppresses Bao temper with fire, at first sound is met very Sharp, it is high probably put very the cause that use up, everything is met after be being appeared in complete Bao sound is to go for certain most all, but need of method of chance of this kind of Bao has more thorough knowledge to HIFI, it is careful and easy to do not take care sound of pair of unit, cent implement make it harm, whether should consider to want to take a risk to get seriously most, most the Bao refine effect that removes a ground? On the condition whether concessional? Because although receive the horn only face-to-face,turn over the noise after the photograph,still can comparative tremendous reach your person to make a noise ear is intolerable, the reader that I think to accuse only has so one clique does not suggest everybody is pursued however theoretically, still be according to gentle Bao engine order goes undertaking comparative dovish, and on effect also enough satisfactory.
