Reviews[edit]
- Anno 1978, the PS-X 7 was the largest fully automatic turntable at Sony, next to the large Sony PS-X 9, which was also offered as a studio turntable.
- The chassis was made of the low-resonance SMBC material in (plain) grey. This is an extremely hard mixture of PVC, aluminum, and yet another material that Sony is silent about. It is harder than some metals, I - "Phonogen" - found out when installing a new (thicker) cable.
Quartz-controlled direct drive (brooms up to 150 g are compensated without problems)
- Synchronization fluctuations: 0,045%
- Rumble noise voltage ratio: 79 dB
- Extremely low-mass carbon tone arm with standard (SME) headshell
- 3 plate sizes adjustable
- Gel pad to increase the inertia of the platter
- Sensor buttons (Start/Stop and Repeat) for vibration-free operation with closed hood
- Optoelectronic limit switch
- Stroboscope with own frequency (120 Hz !) for even more precise speed control
- Similar Sony turntables:
- Sony PS-X 4 identical but only semi-automatic.
- Sony PS-X 6 identical but without carbon tone arm
- "Phonogen": I had few problems even with the digital recording of the legendary Tchaikovsky 1812. Even top-class turntables had to give in, some vinyl and audio freaks claimed that the right-angled deflections of the record were not playable, but the Sony disproved this ;-)).
