Rather than building in unnecessary circuitry, the 3CDT focuses on the mechanical and digital stages of disc playback, sending a clean digital output to an external DAC.\u003c\/p\u003e\n\u003cp\u003eDesigned as the natural companion to the Quad 3 integrated amplifier, the 3CDT is built to match its compact chassis, classic detailing, and DAC architecture. It will also integrate into other high-quality digital systems, providing coaxial and optical digital outputs for use with a separate digital-to-analog converter.\u003c\/p\u003e\n\u003ch4\u003eAccuracy and Integrity\u003c\/h4\u003e\n\u003cp\u003eAt the center of the 3CDT is a high-precision CD mechanism with a custom CD servo control system. Quad has optimized the laser assembly and servo architecture to minimize read errors, jitter, and distortion, helping preserve the integrity of the original CD signal.\u003c\/p\u003e\n\u003ch4\u003ePower and Clock Architecture\u003c\/h4\u003e\n\u003cp\u003eThe internal power architecture separates the motor and laser servo circuits from the decoder stage that retrieves the digital audio signal. A temperature-controlled ultra-low-jitter crystal oscillator provides the master clock for the servo and decoder section, with its own independent low-noise supply and grounding scheme.\u003c\/p\u003e\n\u003cp\u003eThree independent low-noise voltage regulator circuits are dedicated to the CD servo, while the TCXO clock circuit is powered by an ultra-low-noise linear regulator. The advanced CD servo and control architecture uses a dual-core processing framework with a high-performance 32-bit RISC CPU and dedicated MCU for servo control, disc access, and error correction.\u003c\/p\u003e\n\u003ch4\u003eQuad 3 Synergy\u003c\/h4\u003e\n\u003cp\u003eWhen partnered with the Quad 3, the 3CDT offloads digital-to-analog conversion to the amplifier’s DAC architecture. This keeps the transport focused on clean digital retrieval and output, while the Quad 3 handles conversion and amplification in a visually and functionally matched system.\u003c\/p\u003e\n\u003ch4\u003eClassic Design, Modern Execution\u003c\/h4\u003e\n\u003cp\u003eThe 3CDT mirrors the design language of the Quad 3, with a compact chassis, understated styling, and classic Quad detailing. Internally, the transport mechanism is shielded against vibration and electrical interference, with attention paid to durability, quiet operation, and digital signal integrity from the disc tray through the outputs.\u003c\/p\u003e\n\u003ch4\u003eMulti-Format Playback\u003c\/h4\u003e\n\u003cp\u003eIn addition to standard CD playback, the 3CDT supports CD-R, CD-RW, and data CDs, with playback of FLAC, WAV, WMA, MP3, and APE files.\u003c\/p\u003e\n\u003ch4\u003eAbout Quad\u003c\/h4\u003e\n\u003cp\u003eFounded in London in 1936 by Peter Walker, Quad has built its reputation on disciplined engineering, practical design, and the enduring goal Walker described as “the closest approach to the original sound.” Originally focused on amplifiers and public-address equipment, the company moved to Huntingdon, Cambridgeshire, in 1941, where Quad’s British engineering, service, and development remain centered today.\u003c\/p\u003e\n\u003cp\u003eQuad’s history includes some of the most important products in British hi-fi, from the Quad II amplifier and the 33\/303 preamp and power amplifier combination to the 405 current-dumping amplifier. In 1957, Quad introduced the world’s first production full-range electrostatic loudspeaker, establishing a loudspeaker lineage that continues through generations of ESL designs.\u003c\/p\u003e\n\u003cp\u003eToday, Quad continues to balance heritage and renewal, developing electronics and loudspeakers that respect the company’s classic design values while addressing modern listening habits. Across its amplifiers, digital components, and loudspeakers, Quad remains defined by clarity, restraint, and engineering purpose.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDedicated CD transport designed for use with an external DAC\u003c\/li\u003e\n\u003cli\u003eHigh-precision CD mechanism\u003c\/li\u003e\n\u003cli\u003eCustom-designed CD servo control system\u003c\/li\u003e\n\u003cli\u003eLaser and servo architecture optimized to reduce read errors, jitter, and distortion\u003c\/li\u003e\n\u003cli\u003eInternal power architecture separates the motor and laser servo circuits from the decoder stage\u003c\/li\u003e\n\u003cli\u003eTemperature-controlled ultra-low-jitter crystal oscillator master clock\u003c\/li\u003e\n\u003cli\u003eIndependent low-noise supply and grounding scheme for the TCXO clock\u003c\/li\u003e\n\u003cli\u003eThree independent low-noise voltage regulator circuits for the CD servo\u003c\/li\u003e\n\u003cli\u003eUltra-low-noise linear regulator for the TCXO clock circuit\u003c\/li\u003e\n\u003cli\u003eDual-core servo and control architecture with 32-bit RISC CPU and dedicated MCU\u003c\/li\u003e\n\u003cli\u003eCoaxial and optical digital outputs\u003c\/li\u003e\n\u003cli\u003eIlluminated 10.9 × 159 mm full-view LCD display\u003c\/li\u003e\n\u003cli\u003eRemote control functionality\u003c\/li\u003e\n\u003cli\u003eSupports CD, CD-R, CD-RW, and data CDs\u003c\/li\u003e\n\u003cli\u003eSupports FLAC, WAV, WMA, MP3, and APE file formats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eCompatible Disc Types:\u003c\/b\u003e CD, CD-R, CD-RW\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCompatible File Formats:\u003c\/b\u003e FLAC, WAV, WMA, MP3, APE\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDisplay:\u003c\/b\u003e Illuminated 10.9 × 159 mm full-view LCD\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDigital Output Interface:\u003c\/b\u003e 1 coaxial, 1 optical\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDigital Output Amplitude:\u003c\/b\u003e 500 ±50 mVpp\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOutput Impedance:\u003c\/b\u003e 75 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSampling Rate:\u003c\/b\u003e 44.1 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eStandby Power Consumption:\u003c\/b\u003e \u0026lt;0.5 W\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDimensions (HLW):\u003c\/b\u003e 3.98\" × 11.81\" × 11.81\" (101 × 300 × 300 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 11.84 lb.
