JVC Mobile Audio Components 1991

JVC CD Technology

JVC's mobile CD components utilize advanced digital technologies for exceptional sound quality and performance. Key innovations include:

• 1-Bit DA Converter: JVC employs 1-Bit DA converters, including the PEM DD (Pulse Edge Modulation Differential Linearity Errorless DA) converter, which provides superior linearity and eliminates zero-crossing distortion for vivid and clear sound. This technology enhances resolution and the signal-to-noise ratio.
• Oversampling Digital Filter: All JVC mobile CD components feature quadruple digital oversampling to shift noise to inaudible frequencies, ensuring accurate phase response and a high S/N ratio. The XL-G4500 model utilizes an 8-times oversampling digital filter for enhanced digital purity.
• High-Precision 3-Beam Laser Pickup: A precision 3-beam laser pickup system ensures accurate focusing and tracking with high sensitivity. The lightweight assembly improves response speed and minimizes servo system noise.
• Vibration and Heat Resistance: JVC CD components are engineered to withstand the demanding car environment with oil-dampened, rubber-encapsulated springs for shock absorption and heat-resistant materials for the focusing lens, protected by a posistor-equipped circuit.
• CD Operating Convenience: Features include a CD cartridge loading system for user convenience and disc protection. Models offer Direct Access to tracks, Random Play, Intro Scan, Repeat modes, and Track Skip for an enhanced listening experience.
