This is the
next-to-the top-of the line Shure pick-up, which incorporates the same stylus
as is used in the top-of-the-line model. Overall the sound quality is very
good, with slightly hot highs, with user-replaceable stylus (which may also be
used by those who now own the M95 pickup) .
A magnetic pickup
with a "Hyper-elliptical" stylus and built-in "hinged" stylus
guard. Recommended vertical tracking force is 3/4 to 1-1/2 grams and best
rsults were attained in the 1-1/4 to 1-1/2 gram range.
The Frequency
Response measured ±3 dB from 20 to 15,000 Hz, rising to +4,5 dB at 20,000 Hz.
Overall channel balance was within 2 dB. The worst-case stereo separation was
23 dB at 1000 Hz; 20 dB at 15,000 Hz.
This pickup sounds a
lot better than it measures.

Con un peso de un gramo, es correcto aplicar una fuerza centrifuga de un gramo y medio. ?? para corregir la centripeta del surco del vinilo.?? Gracias por su atencion.
ReplyDeleteDesde aquí parece demasiado. Yo te recomendaría usar el método de SoundSmith para determinar la fuerza a utilizar, pon la aguja en la parte de vinilo liso entre la última canción de la cara y la galleta. Si la tienes demasiado alta, la aguja se irá hacia el exterior del disco, y si la tienes demasiado baja se irá rápidamente hacia el centro. SoundSmith recomienda ajustar la fuerza de modo que la aguja no se mueva, o que se mueva muy muy ligeramente hacia el centro. No sé si me he explicado bien, pero si no te recomiendo buscar dicho método en Google o en YouTube.
