Ich hatte selbst mit der digitalen Einspielung der legendären Tschaikowsky 1812 wenig Probleme. Selbst hochkarätige Plattenspieler mussten da klein bei geben, manche Vinyl und Audiofreaks behaupteten die rechtwinkligen Auslenkungen der Platte seien nicht abspielbar, was der Sony aber widerlegte ;-)).<p>

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:
  • "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 ;-)).
