Tonearm and Gimbal Suspension.
The
four-point gyroscopic gimbal, with mass-free vertical tracking force, is
featured in the CS 505-1 as well as in the higher prieced Dual turntables.
Thus, the CS 505-1 has the same gyroscopic bearing principle as the navigation
instruments used in areonautical engineering. The advantages absolutely minimum
bearing friction, no change in tracking forces and uniformly excellent tracking
properties under all operating conditions. Even in the case of warped records
or when the turntable is not quiter precisely horizontal. This is the highest
precision bearing technology typical of Dual quality.
The
U.L.M. Tonearm. Less than half the effective mass of convencional high-quality
tonearms. Clearly lower harmonic distortion and audibly better tracking even
with warped records.
The
special XM 300 alloy. High strength and outstanding internal damping. No
flexural resonance from 60 to 80 Hz, no torsional resonance from 300 to 400 Hz.
Better stereo separation.
The
tonearm suspension. Four-point gimbal. Only 0,07mN bearing friction and
mass-independent tracking force. Perfect balance in all planes of motion.
U.L.M.
Cartridge. Ortofoon TKS 52 E with elliptical stylus. (Optional and extra).
Dual belt
drive. High reliability and long maintanance-free operation thanks to automatic
speed pre-selection and the flat belt precision ground to 2/100 mm.
Pitch
control. Fine speed control by means of the vario-pulley with a 6% control
range.
Full size
platter with damping soft rim mat.
Two-scale
anti-skating control with long precision spring. Specially calibrated to the
low friction bearing of the U.L.M. Tonearms.
Pilot
lift. A unique safety feature that automatically engages the cue control when
the tonearm is lifted from its rest post and moved toward the record. The
tonearm then remains suspended over the record until released by the cue
control to begin play.
Automatic
stop. This raises the tonearm at the end of a record and switches off the
motor.
Automatic
cover tild-hold with continuously variable tension.
