Sansui XR-Q11 turntable

Minicomputerized Turntable

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.
