Sansui's model
XR-Q11 turntable features an internal minicomputer that can be programmed to
play up to seven selections on a record side in any desired order. After
programming the unit's operation is completely automatic from initial cueing to
the final arm return and motor shut-off. Electronic sensors constantly monitor
the operation to ensure smooth and accurate performance, and to protect the
stylus and record. It has a "fail-safe" provision that shuts the
turntable down and illuminates a waring indicator in the event of a
malfunction. All controls are up front and outside the dust cover for
convenience and added record protection. A dual-head magnetic sensing system
measures platter speed by reading magnetic pulses. It has five times the
accuracy of conventional systems, according to Sansui, and triggers a
fast-acting quartz-servo speed correction system. Wow and flutter have been
reduced to 0,015 percent, and Signal-to-Noise ratio is 78 dB.
The tonearm is a
patent pending DOB unit which makes use of optimum pivot-point technology. The
straight, low mass arm is pivoted at the exact point that minimizes vibration
transfer. Dynamic balance is said to be nearly perfect. The DOB arm suspension
and special high-density BMC (Bulk Molding Compound) turntable base form an
effective barrier against acoustic feedback. Even more feedback isolation and
protection is provided by mounting the motor and arm on a rigid cast-zinc
subassembly within the turntable base.
