Quartz-Locked Automatic Turntable
The electro-dynamic servo tonearm of the QL-Y7 is controlled by two coreless linear motors, one to balance the arm in the horizontal plane, the other to balance the arm in the vertical plane.
Working together with two electro-mechanical servo systems, the QL-Y7 tonearm damps resonance and allows the play of even severely warped records.
Optimum tracking force and anti-skating force are electronically applied to the arm.
Three simple controls make operation of the arm a snap.
Other standard features include a cog-free coreless DC servo motor regulated by a double-servo quartz system for amazing speed accuracy, and foolproof computerised tonearm operation.
Completing the QL-Y7 are convenient up-front controls, a vertical tonearm height adjustment and LED indicators for platter speed.
And befitting a state of the art turntable, there's one final touch, a sturdy cabinet trimmed with rosewood veneer and polished to a rich mirror-like finish, for a truly luxurious furniture appearance.
