SL-Q303
Commentary

A direct drive full auto player with quartz phase locked control.

The cabinet is made of precision aluminum die-cast, and TNRC is used for the bottom base.
In addition, a double anti-vibration structure (double opposed suspension) is adopted, making the structure strong against external vibration and excellent acoustic characteristics.

Quartz phase-locked control is used to control the rotation of the turntable with quartz accuracy.
A highly reliable all-round detection FG is used for rotational speed detection, and combined with an integrated D. D. structure and a two phase full-wave drive planar opposed slotless DC motor, excellent rotational performance is achieved.

The tone arm uses a gimbal suspension system with a 4-point support structure using a pivot and ball bearing.
This system has a structure in which the axes of the horizontal and vertical rotation axes intersect at one point, and has obtained a high initial motion sensitivity of 7 mg.

The cartridge is a MM type cartridge that uses an all-laminate core for the magnetic circuit.

The presence or absence of records is automatically detected by the record detection mechanism in the turntable.
In addition, if a record is not set, the tone arm is designed so that it does not move from the rest even if the player is started, preventing arm malfunction.
The detection mechanism automatically detects the record size of the 30 cmLP and 17 cm EP discs, and an internal mechanism guides the tone arm to the outermost groove of the record according to the record size.

The soft operation mechanism adopts a front operation method using an electronic control soft switch.
This allows control with the dust cover closed.

Equipped with a single-row strobe and prism strobe illuminator.

Equipped with needle pressure adjustment and anti-skating mechanism that can be finely adjusted at 0.1g intervals.
