DENON DCD-1500 (1986) | Super Linear

 

The Denon DCD-1500 is a high-performance CD player engineered to deliver exceptional sound quality through a range of advanced digital and analog technologies. At its core is Denon's innovative Super Linear Converter system, which minimizes D/A conversion errors by adding a correction signal generated through an error detection and compensation circuit. This effectively eliminates the zero-cross distortion commonly associated with early CD players, resulting in smoother, more accurate audio reproduction. The DCD-1500 employs two Super Linear Converter circuits along with a dual D/A converter architecture, using independent digital filters for the left and right channels to improve channel separation, stereo imaging, and overall sonic precision.

To ensure outstanding digital performance, the player features a high-precision 2x oversampling digital filter with an ultra-flat frequency response, complemented by Denon's Computer Analyzed Linear Phase analog filter, which maintains exceptionally linear phase characteristics and flat group delay up to approximately 30 kHz. The transport mechanism is designed for stability and reliability, utilizing a newly developed three-beam optical pickup with fast-response servo circuitry for highly accurate tracking and focus control. A rigid glass fiber-reinforced BMC (Bulk Molding Compound) pickup base, a vibration-isolated floating chassis with Q-Dump construction, and a magnetic disc clamper work together to minimize the effects of vibration and resonance during playback.

The DCD-1500 also benefits from a sophisticated power supply design, with separate regulated power sources for the digital, servo, audio, and display circuits to reduce electrical interference and preserve signal purity. Its DC-coupled audio output stage with servo control further enhances sound accuracy. In addition to its audiophile-grade engineering, the player offers a comprehensive feature set including programming for up to 20 tracks, direct track access via a numeric keypad, index search, quick track selection, A-B and program repeat modes, timer playback compatibility, variable analog output, a dedicated subcode output terminal, and a supplied wireless remote control, making the Denon DCD-1500 a versatile and highly capable vintage CD player.Dimensions: 434 x 89 x 350 mm (WxHxD)
