Dual CS 528
Fully automatic belt-drive and ULM tonearm with reliable ease of operation.
The Cs 528
is a fully automatic HiFi turntable. It automatically performs all tonearm
functions such as lowering, raising, returning the tonearm, and switching off
the turntable. This ease of operating guarantees maximum protection of the
stylus and records. These operating features are perfected by viscous-damping
of the cue control, fine speed vario-pulley control and the cover with variable
tilt hold.
Tunable
acoustic isolators effectively suppress noise stimuli in 30 to 45 frequency
range.
High Damping
Compound (HDC) housing. A new material especially developed for this new
generation of turntables. High internal damping and effective suppression of
external interference.
Dual belt
drive. High reliability and long maintenance-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.
Stroboscope
speed monitoring.
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 ULM tonearms.
Viscous-damped
cue control with easy-to-operate soft-touch buttons. Vibration-free front panel
operation.
Automatic
cover tilt-hold with continuously variable tension. The turntable can be
installed close to walls or in furniture.
The ULM
tonearm. Less than half the effective mass of conventional 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 flexuural
resonance from 60 to 80 Hz, no torsional resonance from 300 to 400 Hz. Better
stereo separation.
The tonearm
suspension. Four-point gimbal. Only 0,07 mN bearing friction and
mass-independent tracking force. Perfect balance in all planes of motion.
ULM
cartridge; Ortofon TKS 55 E with elliptical stsylus. (Optional and extra).
Their tests
of ULM led to these reports:
"Navigating the worst warps we could find, the
Dual/Ortofon combination proved very agile indeed, with nary a
mistrack." -High Fidelity
"…tracked
the most severely warped records in our collection, usually so well that we
heard nothing wrong." -Stereo
Review
"Even a
serve warp that would normally throw the pickup into the air will usually give
no more than a slight 'thump' … and most warps are undetectable by
ear." -Popular Electronic
"The
Dual takes dead aim at the fiend of disc reproduction - the warped record - and
response to record warps practically is eliminated at the source." -Stereo
