Brand New TRIO KP-3021 Turntable

Brand New TRIO (KENWOOD) KP-3021 2-Speed Belt-Drive Turntable 1972


Trio KP-3021 is a revolutionary automatic turntable. Thanks to the 24-pole synchronous motor employed exclusively for the arm’s operation, all the automatic functions – auto-play, auto-return, auto-repeat and auto-stop – are electrically operated. This means KP-3021 has completely overcome the troubles conventional automatic players often suffer from. Even when you happen to mistake the handling, KP-3021’s fool-proof mechanism won’t be out of order.

Special Features

Automatic Mechanism

A high quality 24-pole synchronous motor is employed exclusively for the arm operation. This means all the automatic operations are done electrically. Besides the convenience, Trio has brought reliability, smoothness and durability to the KP-3021. you seldom meet the accidents or troubles in the automatic mechanism. Even when you mis-handle, neither mechanism nor disc is injured. What is required to you is to switch on and  to fully rely on the KP-3021.

Automatic Operations

Auto-play – Push soft the control panel and the turntable rotates. At the same time the arm leaves the rest and gently goes down on a disc.

Auto-return – When the disc playing ends, the arm returns to the rest and the power switch turns off. No harmful side-force affects on the stylus.

Auto-repeat – By the slide-type switch the disc playing can be repeated.

Auto-cut – When you want to discontinue the playing, push the control panel. The arm rises and returns to the rest.

Disc Size Selector

According to the disc on the turntable please set the lever beforehand at either of 30, 25 0r 17. the stylus then sinks accurately on the starting point.

Manual Operation

By setting the lever at the position “Manual”, the KP-3021 can be operated manually. For manual convenience the Arm Lifter is attached. Another enjoyment may be yours through hand-operation.

Belt-Drive System

For the drive system Trio employs a specially developed 4-pole outer-rotor hysteresis synchronous motor which provides constant rotation with far less wow and flutter. In addition, the belt drive system offers superb signal to noise ratio.
