Kenwood KD-4100


The coreless and slotless DC motor of the KD-4100/4100R turns at precise servo-controlled speeds for outstanding performance in terms of rumble, wow and flutter.

These full electronically-controlled, fully-automatic turntables are designed with Kenwood's state-of-the-art technology.

Only a feather touch of the operation switch is required to activate the tonearm, start play back and return the tonearm after play back. In the repeat mode or during playback, the auto-cut function can be actuated and manual operations can be performed.

Variable speed control permits precision speed settings using the power-line frequency as the reference, but can be varied ± 3% for music pitch-matching.

The precision tonearm is static balanced with anti-skate correction and uses an EIA plug-in headshell. A viscous damped cueing lever raises and lowers the tonearm for gentle pause operations.

The chassis base is of Anti-Resonance Compression Base (ARCB). This is compression molded from limestone powders, glass powders and polyester resin to provide the ideal base structure.

The KD-4100R model also includes a remote control jack which allows remote automatic playback, repeat playback, auto-cut function and size selection.
