但关于马兰于PM-16功放,本人翻查了大量的音响刊物及上网查讯,却只有大量关于马兰士pm-14及pm-17的评论。
现请主持点评马兰士pm-16功放的声色,特点及与pm-14和pm-17有何不同？达到何等级别？另请推荐一台中低价位的LP唱盘。
望主持先生能抽空解答我的难题。
答：建议用PM-16推奥地利的维也纳的海顿扬声器，此箱的价格约8800元，或者选丹麦的SEK的S11，此箱价格约14800元。
这样的搭配比较合理，声音的表现也比较完美。
LP转盘可以考虑下美国的音乐教堂的唱盘。
问：请问BRYSTON 7Bst 和7Bst Pro ，BP-25前级的价钱，有现货吗？答：这套器材全部大概7万元左右，具体要与代理那边联系下才知道有没有现货，他们的电话是，。
问：本人想查询英国ATC音箱的中国(广州市)代理商是谁? 答：他们的代理的电话是，问：我于今年购得森海塞尔HD580耳机一副，望推荐耳放（国产，进口）及讯号线，现看中科颂U5及VHL 102D，不知此番搭配是否妥当。
另外，不知国产的滤波器效果如何望指点一二，平日喜欢听人声和小的作品，如钢琴、小号的小段，听感要求细节丰富，富有音乐感和层次感，对低频要求不高答：耳放可以用英国瑟顿SUGDEN或者意大利的BLUE NOTE的产品。

Registrationenables us to keep you posted onour latest advancements, andhelps us to better understand ourcustomers and build productsthat meet their needs andexpectations.3CHAPTER 1 –LEGACY:THE HISTORICAL DEVELOPMENT OF THE JBL PROJECT LOUDSPEAKERSOf those few who seek perfection in sound reproduction, only a handful have actually achieved it. The price is always high. It is a rare occur-rence indeed when an individual or group is able to triumph over the constraints of economic and tech-nological reality even once.At JBL, this has happened eight times. In each case, its engineers were told to build the speaker sys-tem they had always wanted to build. Whatever resources were required would be made available. Thus began an ongoing investiga-tion into new frontiers of sound reproduction, beginning in 1950, and continuing to the present day. The products that have resulted from this venture are now known as the JBL Project loudspeakers. Each represents the absolute peak of every technological, material and engineering innovation availableat that time, combined into a single system. They are Hartsfield, Paragon, Everest, K2 S9500/7500 and K2 S5500.The newest models are the K2 S5800 and K2 S9800. Although differing in performance details and physical attributes, each of the Project loudspeakers has shared a common objective: to ele-vate sound reproduction to levels defined only by the limitations of existing materials and technology. And despite a spread of nearly 50 years, all Project loudspeakers have shared many common features – testimony to their foundation on the technology and manufacturing techniques upon which JBL was built.DEFINING THE PROJECTCONCEPTThe Hartsfield began a tradition atJBL that continues today. First, engi-neer a product as close to perfectionas possible. When it reaches thatlevel, it is time to make it better.In 1954, the Hartsfield was signifi-cant in that it represented not newtechnology, but rather a new levelof the all-technical manufacturingapproach pioneered by James B.Lansing some 20 years before it.Like its Project series successors,it was a high-efficiency systemincorporating compression drivertechnology, one combining thequalities of high output, low distor-tion, exceptional stereo imagingand fatigue-free listening. Mostimportant, it was the first consumer-available listening system to do so.In this respect, Project K2 S5800is at once the most advanced andsophisticated loudspeaker in theworld today (save for the ProjectK2S9800) and a speaker whosetechnology is deeply rooted in morethan 50 years of tradition. JBL’spresident in 1954, William Thomas,described the Hartsfield as “...thespeaker system we have alwayswanted to build...the finest compo-nents ever made available to seri-ous listeners.”He went on to describe the processbehind his creation: “Most peoplewho own and appreciate fine soundreproduction equipment look for-ward to the day when they will beable to assemble a system withoutlimitation in just exactly the waythey think it should be done.“Periodically, a manufacturer getsthis same feeling....The science ofacoustics has provided us withbasic principles – available to all forachieving precision reproduction.It is only a matter of incorporatingthese methods into a system design,and then taking every bit of troublenecessary to build a system pre-cisely to the design. It isn't easy, butthat’s the way it is done.”The Ranger-Paragon,JBL’s secondProject system, was the first seri-ous attempt at a reflecting speakersystem, and broke new ground inthe concept of stereo imaging.Essentially two independent full-range speaker systems installed ina handsome curved cabinet nearly9 feet long, the Paragon’s enclosurewas treated as an extension of itstransducers. In essence, the systemhad its own “built-in acoustics.” Inmany respects the Paragon antici-pated loudspeaker developmentsthat would occur years – and evendecades – later.For nearly 30 years, the Paragonremained the most acousticallyviable sound system for the home.Today, along with the Hartsfield,it is still the most sought-afterspeaker in the world.In 1986, JBL introduced a newProject system that retained theParagon’s overall sense of musicalitywhile upgrading its character byincorporating three decades’ worthof continuous development in everyfacet of its design. Its name reflectedthe pinnacle of achievement it rep-resented: Project Everest.For the first time, the rest of thesound reproduction chain – and notthe loudspeaker or its transducers –would impose limits on overall sys-tem performance. Like the Paragonand Hartsfield, Project Everestwas built around compressiondriver technology and addresseda more refined stereo image thanwas previously consideredtechnically feasible.45In order to re-create the extremely high dynamic range provided by today’s audio sources, a new low-frequency transducer was used, incorporating a ferrite magnet, 3-inch edge-wound voice coil, and an Aquaplas™-coated 12-inch cone made of Kevlar®composite, a mixture of Kevlar fiber and pulp material that provides increased rigidity. An EPDM rubber sur-round was chosen for both its flexibility and long life. The Symmetrical Field Geometry™(SFG) magnetic structure mini-mizes second harmonic distortion by providing a uniform flux field that avoids uneven cone move-ment. The rigid cast-aluminum frame is also designed to mini-mize distortion, as aluminum has no effect on the magnetic field. Extensive computer-aided engi-neering and design effort made to develop the optimized port tuning employed in Project K2 S5800has resulted in a significant advance in the concept of state-of-the-art bass reproduction. This proprietary align-ment method offers the best damp-ing characteristics and provides extremely fast alignment, eliminat-ing the typical “bass-reflex” sound of a ported system.All three transducers are built using the most advanced materials and precision manufacturing tech-niques refined from renowned JBL professional sound systems.High power-handling capability results in no limitations on the types of source material. Project K2 S5800 has very high input sensitivity;even a relatively small high-end amplifier can provide full dynamic range without compression.Despite its power and sophistica-tion, Project K2 S5800is a marriage of tradition and technology. It reflects the design, engineering and manufacturing expertise derived and refined through nearly six decades of experience that are the exclusive province of one loudspeaker builder: JBL.678910CHAPTER 5 – AMPLIFIER RECOMMENDATIONSNo single type of amplifier is specified for use with the Project K2 S5800 system. The speakers are highly efficient and will operate adequately with an amplifier or receiver of 70–100 watts. However, the transient response and audio definition of a high-end system such as Project K2 S5800 will pick up all inefficiencies and distortion in an amplifier system. For full-range operation, the Project K2 S5800system can be used with an amplifier/receiver of as little as 30 watts. Amplifiers/ receivers of 100–300 wattswill ensure optimum system performance.There is no effective limit to the power handling capabilities of the Project K2 S5800 loudspeakers when driven by consumer audio amplifiers. No damage will occur when used with high-powered components. Source impedance is an important criterion in selecting an appropriate unit; the selected amplifier(s) should have a very high current capacity and must be capable of driving a low impedance load.For bi-wiring or bi-amplificationapplications, four identical ampli-fiers or two dual-channel units maybe used, although specialized low-frequency and high-frequencyamplifiers offer clear advantages.(If four amplifier channels are used,the high-frequency amplifier maybe up to 6dB less powerful thanthe low-frequency amplifier. Dueto the power versus frequencydistribution of the music, the low-frequency section requires approxi-mately four times the power of thehigh-frequency section.)Project K2 S5800specialist dealerscan recommend amplification tobest suit individual needs. In allcases, the left and right amplifiersfor each section must be identical.Make sure that the input sensitivityof the two amplifiers is equal or thatinput level controls are provided tomaintain the proper low to mid/highbalance. If two identical stereoamplifiers are chosen, each amplifiermay be located near a loudspeakerand drive low-frequency and high-frequency sections through shortwire runs.111213¡Bias Battery:The bias battery supplies constant DC bias to the crossover capacitors, eliminating crossover distortion at zero electric potential. Replace the test battery supplied with your system with a9-volt, 006P rectangular battery as soon as possible. Thereafter, although the speaker will function without the battery, JBL recommends that you replace the battery every two years for best performance. Access the battery by unscrewing the cover. Make sure to observe proper polarity when installing the replace-ment battery.™Network Mode Switch:This switch should be left in the “Normal/Bi-Wire” position unless you are connecting the speaker in a bi-amp configuration using two power amplifiers and an external electronic crossover. Access the switch by unscrewing the battery cover. The switch may be adjusted using a flat-head screwdriver.£HF Trim Switch:This switchallows you to adjust the output of thehigh-frequency transducers to com-pensate for the acoustics of yourroom. The +1dB position increasesthe output, the 0dB position is a flat-level position, and the –1dB positiondecreases the output. Each positionwill affect the tonal balance over awide frequency spectrum. Experimentby placing the switch in each positionwhile listening to familiar programmaterial and choose the position thatsuits your room acoustics and listen-ing preferences. You may find thatafter a few months, once the trans-ducers have settled in, that anotheradjustment is necessary. This isnormal. Access the switch byunscrewing the battery cover. Theswitch may be adjusted using aflathead screwdriver.¢Mid/High-Frequency InputTerminals:For bi-wire or bi-ampconfigurations, connect the speakerwires for the mid- and high-frequencyranges to these terminals.∞Shorting Bars:Leave the short-ing bars in place only if you are usingthe passive single-wire connectionoption described on page 15.Otherwise, remove the bars to pre-vent possible damage to the speakersor your electronics.§Low-Frequency InputTerminals:For bi-wire or bi-ampconfigurations, connect the speakerwires for the low-frequency range tothese terminals.14Figure 9. K2 S5800controls and connections.1516CHAPTER 8 – PROJECT K2 S5800CARE AND MAINTENANCEThe Project K2 S5800loudspeaker system is sprayed in a poly-urethane finish and requires no maintenance other than an occa-sional dusting with a soft, dry, lint-free cotton cloth.The horns may also be wiped with a soft cloth. Treat the surface very carefully to avoid scratching the finish. To remove fingerprints and smudges, apply a small amount of ammonia-free window cleaner to the cloth and gently clean the surface.Never use any abrasive cleaners or chemicals to clean the enclo-sure. If the enclosure becomes perceptibly scratched or other-wise damaged, consult a qualified furniture repair shop.The grilles should never be washed in water, which might cause discoloration or sagging. The grilles may be cleaned using a vacuum cleaner with the suc-tion set extremely low.Should you wish to clean thewoofer surfaces, use a soft, drypaint brush to carefully sweep thedust away. Never use a damp cloth.JBL’s unique Charge-CoupledLinear Definition system is usedfor the crossover network, inwhich a direct (DC) bias current isconstantly applied to the capaci-tors in the network circuit to acti-vate the elements, eliminatingcrossover distortion at zero elec-tric potential.The battery has a life of about twoyears. Even if the battery voltagedrops, the network will continueto function. However, in order tomaintain superior sound quality,we recommend that you test andchange the battery once a year.Note that the battery may leakand damage the holder and otherparts if it is left in the speaker for along period after exceeding thesuggested duration.To access the battery, unscrewthe battery cover at the top ofthe terminal board and remove it.Always use a 9V, rectangular006P-type battery and install itwith the proper polarity.The battery included in theshipped system is for testingpurposes only. We recommendthat you replace it as soon aspossible.All wiring connections should beinspected and cleaned or remadeperiodically. The frequency ofmaintenance depends on the met-als involved in the connections,atmospheric conditions, and otherfactors.

Wiring Precautions●Ensure that the positive (+) and negative (-) bare wire or spades DO NOT touch each other when connected to the binding posts as this will short out the amplifier channel.●Ensure that the appropriate polarity is maintained from amplifier to speaker to ensure proper phase for both speakers.4 Post Terminals / Dual Sets of Binding Posts Terminal Wiring Options2-Wire ConnectionsBasic single-wire connection from amplifierWe recommend using HF Positive and LF Negative.B-Wire ConnectionsTwo-wire connection from single amplifier Remove terminal straps before connecting.Bi-Amp ConnectionsTwo-wire connection from multiple amplifiers Remove terminal straps before connecting.+-Positive + Red Negative - Black+-+-Positive + Red Negative - BlackControls and AdjustmentsThis speaker features a HF level control that can be used to adjust the HF level independently from the level of the woofer.
