Two-Speed direct drive automatic turntable
The newly developed silent synchrotor system, featured in the XR-Q7 turntable, has been proven to prevent the reactionary force generated by the direct drive motor from vibrating the turntable cabinet.
It does so by rotating the silent synchrotor in a direction opposite to that of the direct drive motor at any given moment, thereby cancelling any torque fluctuations as they occur.
Other features of the Sansui XRQ7 include a quartz-servo system for perfect speed control, an amazing vibration free D-O-B tonearm with vibration free tonearm base, precise computer controlled fully automatic operation and a solid platter mat which helps assure optimum reproduction quality.

The XR-Q7 sounded rather loud and forward, with a significant defocusing of central images especially in the midrange, but pitch and timing were however, rather good - £270 HiFi Choice 1983
