Clearaudio Reference Jubilee

The Clear Audio Reference Jubilee Turntable is a high-end, precision-engineered turntable designed for audiophiles and professionals seeking exceptional audio reproduction. Below is a technical description of its key features and components:

1. Design and Construction

• Chassis: The turntable features a rigid, low-resonance chassis constructed from high-quality materials such as aluminum, acrylic, or composite polymers. This minimizes vibrations and ensures stability during playback.

• Platter: The platter is typically made from a dense, non-magnetic material like acrylic or aluminum, designed to reduce resonance and provide consistent rotational stability.

• Weight: The turntable is heavy, which further reduces external vibrations and enhances sound quality.

2. Drive System

• Drive Type: The Reference Jubilee employs a belt-drive system, which isolates the motor from the platter to minimize noise and vibration.

• Motor: It uses a high-torque, low-noise DC or AC synchronous motor, often with electronic speed control for precise RPM adjustments (33 1/3, 45, and sometimes 78 RPM).

• Pulley System: The pulley is precision-machined to ensure smooth and consistent rotation.

3. Tonearm

• Tonearm Type: The turntable is equipped with a high-precision, low-friction tonearm, often made from lightweight materials like carbon fiber or aluminum.

• Bearings: The tonearm uses high-quality bearings to ensure smooth tracking and minimal distortion.

• Adjustability: Features adjustable VTA (Vertical Tracking Angle), azimuth, and anti-skate settings for optimal cartridge alignment.

4. Cartridge and Stylus

• Cartridge: The Reference Jubilee often comes with a high-end moving magnet (MM) or moving coil (MC) cartridge, though it is compatible with a wide range of cartridges.

• Stylus: The stylus is typically a fine-line or elliptical diamond tip, designed for accurate tracking and minimal wear on records.

5. Suspension and Isolation

• Suspension System: The turntable may include a sophisticated suspension system to isolate the platter and tonearm from external vibrations.

• Feet: High-quality, adjustable feet with damping materials (e.g., rubber or silicone) are used to further isolate the turntable from surface vibrations.

6. Speed Control

• Electronic Speed Control: The turntable features precise electronic speed control to maintain consistent playback speed, reducing wow and flutter.

• Speed Adjustment: Some models include a fine-tuning mechanism for speed adjustment, ensuring perfect synchronization with the recording.

7. Connectivity

• Outputs: The turntable typically includes RCA outputs for connecting to a phono preamp or amplifier.

• Grounding: A grounding terminal is provided to eliminate hum and noise.

8. Aesthetic and Finish

• Finish: The Reference Jubilee is known for its luxurious finish, often featuring polished surfaces, high-gloss coatings, or matte textures.

• Customization: Some models offer customizable options for platter mats, tonearm finishes, and other aesthetic details.

9. Performance Specifications

• Wow and Flutter: Typically less than 0.1%, ensuring minimal speed variations.

• Signal-to-Noise Ratio (SNR): High SNR, often exceeding 80 dB, for a clean and dynamic sound.

• Rumble: Extremely low rumble levels, often below -70 dB, to preserve audio clarity.

10. Additional Features

• Dust Cover: A high-quality, hinged dust cover is often included to protect the turntable when not in use.

• Modular Design: Some components are modular, allowing for upgrades or replacements to enhance performance over time.
