Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Technics SL-J11OR is a DC Servo Automatic Turntable System designed for playing vinyl records. It features a "P-mount" plug-in-connector system, ensuring interchangeability and compatibility with other P-mount products. This turntable is designed for ease of use, offering both automatic and manual play options, and includes various features to enhance the listening experience and simplify maintenance.

Function Description

The SL-J11OR operates as an automatic turntable, meaning it can initiate playback and return the tonearm to its rest position automatically. To begin automatic play, the user first removes the dust cover and the stylus protector from the cartridge. The turntable utilizes a "P-mount" plug-in-connector system for its cartridge, which simplifies cartridge replacement as it is pre-designed to match the unit's weight, stylus pressure, and center of gravity, eliminating the need for complex adjustments. After placing a disc on the platter mat, the record size detector automatically identifies the size of the record (17-cm or 30-cm). The user then sets the speed selector to match the disc's speed (33-1/3 rpm or 45 rpm). Pressing the START/STOP switch initiates the platter rotation and tonearm movement, beginning playback.

For 17-cm (7") records with a large center hole, a 45-rpm adaptor is integrated into the unit. This adaptor can be raised by pressing and turning counterclockwise when needed, and pressed down and turned clockwise when not in use.

The turntable also supports manual play for discs other than standard 17-cm or 30-cm sizes, lightweight discs like "Soundsheets," or badly warped discs. In manual mode, after setting the cueing switch to the "up" position, the user can manually move the tonearm to the desired position on the record. The platter will start turning once the tonearm is moved. To lower the tonearm and begin playback, the cueing switch is set to the "down" position.

A key safety feature is the automatic return function: when playback ends, the tonearm automatically returns to its arm rest, and the platter rotation stops. The unit also includes an arm clamp to secure the tonearm when not in use or during transport, and a stylus protector to safeguard the stylus.

The SL-J11OR can be connected to an amplifier via stereo connection cables and features a remote control terminal. This allows for synchro recording with compatible Technics amplifiers that have "SYNCHRO-REC" or "CONTROL" terminals, enabling synchronized recording with a tape deck. Remote control operation is also possible if the amplifier has remote control functions.

Usage Features

The turntable is designed with user convenience in mind. The "P-mount" cartridge system simplifies cartridge replacement, as the new cartridge is pre-matched to the unit, eliminating the need for lead wire connections or stylus pressure adjustments.

An important pre-use step involves adjusting the voltage selector on the rear panel to match the local voltage setting, if applicable for the region. This ensures the unit operates correctly and prevents damage. For countries like the United Kingdom, specific wiring instructions are provided for the mains lead, indicating how to connect the blue (neutral) and brown (live) wires to the appropriate terminals in a plug, adhering to BS 800:1983 standards.

During operation, users are advised not to touch the tonearm while it is moving. If the platter starts or keeps turning unexpectedly (e.g., when the power cord is connected or the start/stop switch is pressed without a disc), pressing the start/stop switch will stop it. In cases where synchro recording might miss the beginning of a tune, an adjustment for the automatic-start position is possible by turning a screw counterclockwise.

For safety, the unit should be placed in a well-ventilated area, at least 10 cm (4") away from wall surfaces and direct sunlight, and away from heaters to prevent damage. It is crucial to use a standard AC wall outlet and avoid high-voltage sources or DC power. Wet hands should not touch the power cord plug, and the cord itself should always be grasped by the plug for removal. The unit should be turned off after use to prolong its operational life.

Maintenance Features

Regular maintenance helps ensure optimal performance and longevity of the SL-J11OR.

Stylus Replacement: If noise is heard from new discs, it indicates a worn stylus, which typically has a life of approximately 1000 hours. Replacing the stylus is a straightforward process: the old stylus is pulled out, and the new EPS-24CS stylus is inserted. Users are cautioned not to touch the stylus tip during this process.

Cartridge Replacement: The plug-in type cartridge simplifies replacement. To replace the cartridge, the tonearm is clamped, a screw is removed, and the old cartridge is pulled out. The new cartridge is then inserted by following these steps in reverse order.

Cleaning the Stylus: Dust on the stylus can affect sound quality. A soft brush or similar material should be used to gently remove dust from the stylus, moving carefully in the direction of the arrow indicated in the manual.

Cleaning Discs: To maintain sound quality, discs should be cleaned occasionally with a high-quality disc cleaner.

Cleaning External Surfaces: For general cleaning of the unit's external surfaces, a soft, dry cloth is recommended. For dirtier surfaces, a soft cloth dipped in a soap-and-water solution or a weak detergent solution can be used, ensuring the cloth is well-wrung before wiping. After cleaning with a damp cloth, the unit should be wiped again with a soft, dry cloth. Importantly, alcohol, paint thinner, benzine, or chemically treated cloths should never be used, as these chemicals can damage the finish.

Troubleshooting: The manual provides a troubleshooting guide for common issues such as the platter not turning, "howling" sounds, or unusual scratching noises. Solutions include re-attaching the belt, stabilizing the turntable's location, moving it away from speakers, using cushioning materials, adjusting amplifier tone controls, cleaning discs and stylus, or replacing the stylus. If problems persist, users are advised to contact their dealer or an Authorized Service Center.
