Pioneer
PL-51
A
professional direct-drive stereo turntable with sophisticated DC servo phono
motor and highly-sensitive S-shaped tonearm.
The ideal
rotation transferring mechanism in any stereo turntable is the direct-drive
phono motor. This highly advanced turntable from Pioneer, the PL-51, is the
first in its practical price bracket to employ this ultra-slow running motor.
Use of this motor means that the turntable platter is directly connected to the
shaft of the drive motor, and thus the PL-51 operates without the use of idlers
or belts as do more conventional turntables. The motor rotation is the
turntable rotation, and the result is extremely quiet, stable turntable
rptation at all times. The motor employed in the PL-51 is the brushless DC
servo-controlled type, compactly designed. Turntable rotation is then kept
stable by the use of an electronic servo circuit that employs semiconductors to
significantly reduce wow and flutter to
less than 0,06% WRMS. Equally important, signal-to-noise ratio of the PL-51 is
better than 55 dB, a fine performance figure that may be compared favorably
with any other turntable on the market. Then, coupled with the direct drive
mechanism, this Pioneer turntable also
uses a highly-sensitive and stable
S-shaped tonearm, perfect for the light-tracking cartridges now in wide use, or
for the new four-channel recordings. Complete with a solidly constructed wooden
cabinet and solid base with large insulators, the PL-51 offers more performance
and value than you've ever thought possible in its price range. Hear it first
and compare.
