Dual 1006/A Record Changer Operating Instructions

Product Overview

The Dual 1006/A is a versatile, high-quality record changer designed for both stereophonic and monaural playback. It offers fully automatic operation for record changing and single-play, as well as manual playback options. The unit supports four speeds (16 2/3, 33 1/3, 45, and 78 rpm) and can handle record sizes from 7 to 12 inches. It features a self-stabilizing changer spindle, an adjustable tracking pressure mechanism with a built-in scale, and a removable cartridge holder compatible with various international Hi-Fi cartridges.

Setup and Installation

Before operating the unit, it is essential to remove the two transit screws to allow the spring suspension to function correctly. The device must be configured for the local power line voltage (110/125V or 220/240V) using the voltage selector located under the unit. Ensure the motor pulley is set for the correct power line frequency (50 or 60 cycles) by interchanging the bushing on the motor shaft if necessary. The unit connects to an amplifier via a standard cable with specific color-coded plugs: red for the left channel and yellow for the right channel.

Operation

The Dual 1006/A is controlled via a set of push-buttons. The Start key initiates automatic operation. The Stop key allows for an instant stop, where the tone arm returns to its rest position and the equipment shuts off. For repeat playback, the Repet key is used. The unit can be operated as a record changer by inserting the changer spindle, or as an automatic/manual record player by using the short spindle. For manual operation, the tone arm is placed on the record by hand, and playback is started by pressing the Manual key.

Cartridge and Stylus Maintenance

The unit comes equipped with the Dual CDS 420 crystal cartridge. Tracking pressure can be adjusted using the regulation screw and verified using the built-in scale. It is crucial to maintain the stylus to ensure high-fidelity reproduction and protect your records. Replace the stylus periodically; always use original Dual replacement parts to avoid potential damage to the equipment or records. When installing different cartridges, ensure the correct spacers and mounting screws are used to maintain the proper distance and tracking geometry.

Safety and Care

When connecting the unit to receivers with autotransformers or for commercial use, ensure proper chassis grounding as required by safety standards. Keep the unit clean and handle the tone arm with care to avoid damaging the delicate internal mechanisms. If the unit is not functioning correctly, check the power supply settings and the cartridge connections before seeking professional service.
