2-Speed Direct-Drive Turntable (1980-1983)
The Kenwood engineers designed the L-07D to absorb vibration over the entire audible frequency range, and used a highly rigid construction to prevent signal loss through vibrational movement.
The direct-drive system of the L-07D incorporates a highly sophisticated quartz-lock, speed-phase double servo control and constant-current type motor to maintain high accuracy in motor speed.
Another unique feature incorporated in the L-07D is the structured platter.
The massive die-cast aluminium platter is reinforced beneath by a 4mm thick, duralumin layer.
But on top of the platter is a second layer of 5mm thick, vibration proof stainless steel.
The two surfaces are interfaced by precision machining to prevent ringing, while the non-magnetic nature of the steel serves as a barrier to magnetism generated by a moving coil type cartridge.
