1. Introduction
The Boston Acoustics currently offers an enormous variety of products, since the installations acoustics for automobile, until systems with certification THX, passing for a rigorously conceived article line for use in small spaces and personal computers.
Of this making, I had the happiness of being able to hear the Digital Boston Theater 6000 [ DT6000 ], that it consists of five small columns of one alone altifalante, and in subwoofer that integrates descodificação and amplification for modalities stereo, Digital Dolby [ DD ], and Dolby ProLogic [ DP ]. The DT6000 includes all the necessary handles, one telecomando very easy one to use, and supports who will be interested in fixing the columns in some surface.
One of the five supplied columns is different of the others, and for being destined there to make of central canal, also it makes the reception of the signals of telecomando and gives indication of the active configuration: volume of hearing, which the source of signal seleccionada, which the way of ambiência in functioning, and until illustrates which the active columns at the moment.
Telecomando supplied is said universal, in the direction of that using the code correcto of the equipment to control, will be able to function with hundreds of devices, the most diverse manufacturers! The entrance of the code of 3 digits that defines the manufacturer is trivial, consisting of not more of the one than five pressures of keyboard key... (beginning/code/end).
It has many situations where the physical space limits and determines the options that if take. For example, no matter how hard somebody if feels fascinated by the involving sound of the calls hearings home-cinema , to usufruct of this allure in the comfort of the home, it has months behind, it did not have another solution, that not to invest it in the voluminous hardware.
It happens that this solution was not permissible in many scenes, and the massificação of the home-cinema was being postponed until recently, when they had started to appear proposals that do not admit excuse, and that the necessities cover all rigorously, since the one of the customer that are only interested in most good, without the minimum restriction, until the a of the customer who will finish for having to use radio headphones surround .
The Digital Boston Theater 6000 demands little space, but it does not make transmission without wires, what it means that they always go to be necessary handles of linking. The supplied handles are very generous in the extension, and will have to be adjusted to all the circumstances - in case that some of these handles it seems short, perhaps, for its space, make sensible other género of equipment...
Two analogical entrances are available stereo [ VCR IN, AUDIO IN ], and two digital entrances: one for electric Digital Dolby signal [ RCA ], and another one for optic digital signal [ Toslink ]. The exits for the columns become for independent taking RCA, what it means that, in theory, this Boston can be used as only descodificador, sending the signals identified for dedicated external amplification. I did not arrive to try this possibility.
Finally, to relate that all the columns have magnetic shield, of form not to intervene with sensible equipment the magnetic fields, as it is the case of conventional television sets.
The DT6000 is not considered a product Boston Audio Desktop , but it seems me evident that particularly audio-video is indicated not only for installations AV [ ], where if looks an involving sound without complications and demanding a minimum of physical space, but also for installations where if it wants to give a quality voice, to the audio one of personal computers.
I tried it in both the scenes...
2. Opinion
Boogie Nights - the such film 1997 surprise, that it designates the return [ ] of Burt Reynolds, and that counts the history of a set of personages of the industry of Cinema XXX , in the end of the decade of 1970, and in the beginning of the decade of 1980 - was heading DVD that more contributed for my opinion of the DT6000, in uses home-cinema .
Boogie Nights is pejado of saudosos musical moments and dialogues invulgares, as it would be to wait. But despite the radically different argument, happily that P.T. Anderson filmed sequências more typical, that involve, for example, detonations of firearms and accidents of automobile. Happily, because the 155 minutes of Boogie Nights finish for really including a variety acoustics that is not easy to only find in films very tipificados by one género.
The manual of the DT6000 advises to locate subwoofer in one sings, of form to maximize the serious ones, and of this making it will be exactly important to follow the advice, because this Boston is not immediately generous in the low frequencies.
While the volumes of hearing are modest, subwoofer obtains to be obviously present, because it is the only component of the set, theoretically capable to go down to the 50 Hz, while that the altifalantes remains will have difficulties in second making it below of the 100 cycles/. Thus, the not altruistic volumes, have a certain espectacularidade in the low frequencies, that if detach and that they become to feel, in glad coherence with the remaining units, grace of the little directional nature of the raised wave lengths.
But when the volume if becomes less discrete, our direction of hearing tends to be more alert to the frequencies highest, and the serious ones have to grow more of the one than proportionally, to keep the presence prominence, that before assured. It is this growth that can not verify, what it becomes the system "levezinho" in some tickets, if the user will not have been strengthenn for optimizar the position of subwoofer .
In all the case, to little when advantage of its localization is taken off, the serious box of [ and descodificação + amplification ] of the Boston is in harmony with the columns satellite, and obtains to reproduce impressive tremors, who to believe that the same ones have origin [ only ] in the small altifalantes. If to everything this to add a mannering linearity, and - above of everything - one very good descodificação Digital Dolby , then the DT6000 constitutes a proposal much more serious, of that the first moments can suggest!
The quality of descodificação DD of the DT6000 starts to be evident, in fílmicas sequências of some literal movement, as when the producer of Boogie Nights , "sweeps" the party of farewell of the decade of 1970. During the visual displacement, the equivalent happens displacement acoustics, folloied of rotation, will be the case! The level of the information frontal, the dominant sensation, is of that somebody is to push the columns of sound of the party, in the contrary direction to the one of the movement, what in the case concrete means that the sound runs away for the right, while we have right to see what it is transferred to the left; but the level of the posterior columns, the reproduced information has more interest, because she is more complex, corresponding to a scene where they change the characteristics of reverberation of the environment, a time that, the certain height, is jumped of the interior of a habitation, for an exterior garden, with swimming pool, not aired. However the Digital Dolby of the Boston identified the simple displacement, rotations, intensities and reverberações, with the severity the one that completely dedicated equipment to this strict intention, had accustomed me!
With Dolby ProLogic [ DP ], already does not meet reasons for great compliments: the separation between canals does not have pararelo with the best dedicated descodificadores, having a certain extreme promiscuídade, between the central canal and the canals left and right, and the inevitable adormecimento of the posterior columns, puts in charge of one alone information channel, normally little asset. The posterior behavior is inevitable, for nature of [ des]codificação ProLogic , but the canals frontals could more be contrasted.
It is remembered that in DD if they identify 5,1 total independent canals normally: left, center, right, posterior-left, posterior-right and LFE [ Low Frequency Effects ]; while that in DP if they identify 4 canals, that never are completely independent, a time that if they get for operations of phase on analogical information stereo - these canals are: left, center, posterior right and.
Although one very good positional severity, descodificação DD of the Boston finishes for being slightly engaged for the limitations of the small used columns, mainly to the level of the sharps, and particularly when it has that to reproduce high quickly changeable frequencies, as metallic plates of battery, or glasses that if estilhaçam. In these occasions, it lacks a certain naturalness to set DT6000.
Sequências seleccionadas of other films, had helped it to me to be with the following opinion of the DT6000, when used for home-cinema :
- it compensates to lose time to choose the best possible localization to subwoofer it ! It has a very great difference in its performance, when arranged to one I sing "solid", and when arranged in an open space...
- the descodificação Digital Dolby guarantees a reproduction positionally very needs, what it means that the share films go to enjoy themselves with a maximized espectacularidade!
- they are possible very generous volumes of hearing, but the sessions most qualitative, happen the "half gas", when still it is easy to perceive the breath of the serious ones, and when the columns satellites are in conditions of never exceeding the sharps.
- the central column will not have to be very moved away from the columns left and right, duly warned to be necessary greater sonorous pressure, of form to have full perception of all its information. Of this form, a more natural reproduction is still guaranteed, less strengthenn and better complemented for all Boston equips it.
One of the uses most probable of Digital Theater 6000 , will be however with personal computers, now that audio 3D is present in t *** TRANSLATION ENDS HERE ***odo o software de entretenimento, e agora que diverso hardware já disponibiliza saída digital directa, compatível com os fluxos de dados que o Boston sabe descodificar.
Não resisti a sujeitar o DT6000 a títulos como Roller Coaster Tycoon , Hidden and Dangerous , System Shock 2 , Thief , e Unreal , todos muito rigorosos na acústica, seja para recriacção de um ambiente de suspense ou de diversão, seja para realismo e para localização de outras entidades no mundo. Foram sessões de entretenimento muitíssimo agradáveis, que merecem exactamente os mesmos elogios e sugestões, que as sessões de home-cinema !
Alguns dos jogos foram experimentados em estéreo, com muito bons resultados. Só não percebo porque é que foi a coluna central a fazer de coluna esquerda, nessas ocasiões, quando todas as ligações estavam bem feitas e confirmadas pelo sinal de teste...
Ainda assim, o DT6000 deverá ser das propostas mais interessantes para utilização em computadores, que disponham de hardware com saída de áudio digital.
