1. OIL
DAMPED TONEARM
Ordinarily tonearms have a resonance frequency of
between 5 to 10Hz.
If the peak of the range of a
tonearm is too high
, accurate tracking of the tone-
arm with the record groove cannot be obtained be-
cause the tonearm resonates at a frequency generated
by ambient vibrations or sound pressure, or the tone-
arm can be influenced by adverse conditions of the
record such as warps
, etc. The
OIL DAMPED
TONEARM i~ designed to suppress the range of
resonance by maintaining a low resonant point of
the tonearm to prevent howling. With this OIL
DAMPED TONEARM
, accurate tracking of the
record groove as well as a good resistant character-
istic to howling is possible
, thus resulting in an im-
proveved SIN ratio. I
n order to improve the sound
quality, the OIL
DAMPED TONEARM plays an
important role.
