SONY PS-LX55

Commentary

This is a liberty size full auto player with reduced tracking error by adopting a linear tracking arm.

It employs a linear tracking tone arm that reduces sound distortion due to tracking errors. The arm pipe uses a square short span arm that has approximately 70% stronger second moment in section than a round pipe of the same diameter.

It uses a plug-in type shell connector that can replace cartridges designed according to the unified standard.
In addition, the cartridge is equipped with MM type cartridge XL-250G designed based on unified standards for shell plug, self weight, and proper needle pressure.

For the rotating system, brushes and slots are removed from the DC motor, and a linear BSL motor, which suppresses mechanical torque changes called cogging, is adopted.

It uses an opto-electronic disc size selector with a safety design that automatically selects records, accurately leads in, and prevents the needle from dropping when there is no record.

Equipped with a muting mechanism that eliminates the generation of noise when the record board and needle tip contact.

By using the sync unit sold separately, it is possible to play sync with the cassette deck.
