Logic DM 101


The Logic DM 101 is a belt-driven, sprung chassis turntable with AC synchronous motor.

From 1983 onwards the DM101 was fitted with an improved electronic power supply with two-speed switching.

Drive is by a synchronous motor via a precision ground, flat section belt.

The platter is a precision machined item in two-part form, the main platter having a high inertia value.

The main bearing has a die-cast aluminium housing supporting two PTFE bushes together with a carbide thrust pad.

Thrust is taken by a steel ball concentrically located in the end of the ground and diamond lapped spindle.

The 24 pole motor is mounted directly to the plinth on a 5mm thick steel plate.

Manufactured in solid 8mm thick aluminium, the chassis provides a rigid support between the arm mounting and the platter.

The DM101 chassis/platter combination is suspended from the plinth by a unique system known as Logic Mass Centre System.
