Sony PS-2250


The Sony PS-2250 is a professional-type stereo turntable which has many outstanding features.

An advanced servo-controlled direct-drive system eliminates the vibration and noise ordinarily transmitted from motor to turntable, and ensures steady turntable speed.

Motor speed is not influenced at all by the AC power frequency as the independent servo system perfectly controls the AC drive motor.

The well-balanced die-cast aluminium alloy platter is a hefty 3.3 lb.

The resulting inertia moment provides exceptionally good flywheel effect.

The newly designed static-balanced tone arm provides outstanding performance with any high-compliance cartridge.

This precision tonearm incorporates a direct-reading gauge to measure the stylus force, and a simple anti-skating compensator and lateral balancer.

Conveniences on the PS2250 include: a stroboscope to measure the turntable speed, a pitch control to obtain accurate speed, and feather touch speed selectors.
