Cool (L.V.) LEITOR DE VINiS “um problema!?”

SOM IMPERFEITO E RUIDOS PARASITAS

Convensionando aqui ,(100%) a máxima qualidade sonora obtida por por um L.V..
Aquilo que eu acho , os componentes que são os mais responsabilizados a intervirem no apuramento do som, são na minha opinião:
1-Célula fono-captadora/estilete de leitura MM (30%)
( As células MC são de outro estágio.)
1.1-Técnicamente falando nas características principais para uma boa audição generalizada neste caso de células MM:
( As células MC são de outro estágio.)
Frequências de resposta: 20 a 20.000 Hz
Tensão de saída: 3,5 mV a 1Kz é óptimo
Separação de canais : > a 20dB a 1Khz
Capacitância de carga: 100 a 500pF
Resitência interna, deve ser mínima :~410 ohms
O estilete
Com seu cantilever de Carbono é sempre melhor que Alumínio, o diamante elíptico ou esférico?, depende da intenção. O elípt. vai mais profundo e dura mais,e produz bons pormenores de agudos. O esféricocónico geralmente com a maior força de rastreio teóricamente dura menos, é mais notável em médios e graves se a sua dimensão não for além de R6 micrometros.O elíptico também tem os seus normativos: R/r-18/8, -(havendo o caso dos de luxo , que o R vai aos 70 e o r aos 5 micrometros.)
2-O conjunto ;Prato giratório,mancal, guia de eixo ,base de apoio e pré- amplificador integrado no L.V. (30%)
3-Cabos de sinal(25%)
3.1- Os cabos de sinal que interligam cm o amplificador do sistema é bom que sejam quase balanceados e com fio dreno, se não poderem ser balanceados.
4-braço/cabeçote (15%)
Por ordem de avaliação, devemos caprichar na qualidade da célula/estilete, no equilíbrio e na dinâmica do prato giratório, que são também fundamentais.
Nota «- estes parceres são apenas a minha experiência, sem entrar em “audiofulias” e valem o que valem.

IMPERFECT SOUND AND PARASITIC NOISE

Convening here, (100%) The maximum sound quality obtained by a L.V..
What I think, the components that are the most responsible to intervene in the sound clearance, are in my opinion:
1-Sound-captadora Cell/Reading Stylus MM (30%)
(MC cells are from another stage.)
1.1-Technically Speaking in the main characteristics for a good general hearing in this case of MM cells:
(MC cells are from another stage.)
Response Frequencies: 20 to 20,000 Hz
Output Voltage: 3.5 mV to 1Kz is great
Channel Separation: > to 20dB to 1Khz
Load Capacitance: 100 to 500pF
Internal Resitency, should be minimum: ~ 410 ohms
The Stylus
With your Carbon cantilever is always better than Aluminum, the elliptical or spherical diamond?, depends on the intent. The elípt. Goes deeper and lasts longer, and produces good details of treble. The Sféricoclonic usually with the largest screening force theoretically lasts less, is more remarkable in medium and severe if its size is not beyond R6 micrometers. The Elliptical also has its normative: R/R-18/8,-(with the case of luxury, that R goes to 70 and R at 5 micrometers.)
2-The set; Swivel Plate, bearing, shaft guide, support base and pre-amplifier integrated in L.V. (30%)
3-Signal Cables (25%)
3.1-The signal cables connecting the system amplifier are good to be almost balanced and with drain wire if they cannot be balanced.
4-arm/printhead (15%)
By Order of Evaluation, we must strive in the quality of the cell/stylus, in the balance and dynamics of the turntable, which are also fundamental.
Note «-These parceres are just my experience, without going into "audiophulias" and worth what they are worth.
