- In addition to the large Sony PS-X 9, which was also offered as a studio record player, the PS-X 7 was the largest fully automatic turntable at Sony in 1978
- The chassis was made of the low-resonance SMBC material in (edema) gray. This is an extremely hard mixture of PVC, aluminum and yet another material that Sony does not talk about. It is harder than some metals, I - "Phonogen ically" - had to find out when installing a new (thicker) cable
- Quartz-controlled direct drive (brooms up to 150 g are adjusted without any problems)
- Synchronisation fluctuations: 0.045%
- Rumble noise voltage distance: 79 dB
- Extremely low-mass carbon tonearm with standard (SME ) headshell< /li>
- 3 plate sizes adjustable
- Gel pad to increase the mass inertia of the turntable
- Sensor buttons (start/stop and repeat) for vibration-free operation with the hood closed
- Optoelectronic limit switch
- Strobe with its own frequency (120 Hz !) for even more precise control of the speed
- Similar Sony turntables:
- Sony PS-X 4 identical but only semi-automatic
- Sony PS-X 6 identical but without low carbon
- "Phonogen ": I had little problems even with the digital recording of the legendary Tchaikovsky 1812. Even top-class turntables had to give up, some vinyl and audio freaks claimed that the right-angled deflections of the record were not playable, which the Sony refuted ;-)).
- Sony PS-X 4 identical but only semi-automatic
- Sony PS-X 6 identical but without low carbon
