Every detail from your favorite CDs comes alive with breathtaking accuracy. More than just a CD player, the Accuphase DP-450 is a statement piece for any true audiophile. Rediscover the magic of your CD collection.\u003c\/p\u003e\u003ch3\u003eHighly rigid and precise CD drive unaffected by external vibrations\u003c\/h3\u003e\u003cp\u003eThe highly rigid CD drive employs a stiff construction that not only minimizes vibrations from the internal rotation but also absorbs any external vibrations, whether large or small. The rigid mechanism base is fully integrated with the massive and highly rigid chassis, resulting in a strong frame structure with elaborate and sophisticated construction.\u003c\/p\u003e\u003ch3\u003eMDS type D\/A converter\u003c\/h3\u003e\u003cp\u003eMDS (Multiple Delta Sigma) is a revolutionary approach that employs several delta-sigma type D\/A converters connected in parallel, for drastically improved performance. The same digital signal is supplied to each converter, and the output of the converters is summed before being sent to subsequent stages. In the DP-450, four converter circuits are used in parallel. This improves overall performance by a factor of about 2 as compared to a single converter circuit. Because the performance improvement afforded by the MDS principle is independent of signal frequency and signal level, output signal noise at very low levels is also successfully minimized, a feat that is very difficult to achieve with conventional delta-sigma converters.\u003c\/p\u003e\u003ch3\u003eFilter amplifier with ANCC topology\u003c\/h3\u003e\u003cp\u003eANCC (Accuphase Noise and Distortion Cancelling Circuit) is a newly developed topology that improves performance by canceling noise and distortion components. THD is minimised, and noise performance is improved to the level of the canceling amplifier. Gain distribution is optimized through measures such as increasing the gain in the filter circuit's input stage, thereby elevating performance to a level that rivals the technology of higher-ranked models.\u003c\/p\u003e\u003ch3\u003eNon-resonant design\u003c\/h3\u003e\u003cp\u003eIf there is overlap between the rotation frequency of the spindle motor that turns the disc for playback and the resonance frequency of the viscous dampers that support the traverse mechanism, the risk of pickup dropouts increases and sound quality may deteriorate. It is therefore crucial to design the player components in such a way that resonance points within this frequency band are avoided. As a result of numerous listening tests and a series of careful vibration measurements, Accuphase engineers were able to achieve optimum isolation between the traverse mechanism and the CD drive itself. Contact sections of individual metal parts employ a sophisticated frame construction that further contributes to keeping resonances in the pickup vicinity to an absolute minimum.\u003c\/p\u003e\u003ch3\u003eDigital inputs and outputs for COAXIAL, OPTICAL, and USB (input only)\u003c\/h3\u003e\u003cp\u003eHarnessing the high performance of the built-in processing section, data from other digital equipment can be supplied to the DP-450 via the digital inputs and played back with high sound quality.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eFormat:\u003c\/strong\u003e Standard CD format\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuantization:\u003c\/strong\u003e 16 bits\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSampling frequency:\u003c\/strong\u003e 44.1 kHz\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eError correction principle:\u003c\/strong\u003e CIRC\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNumber of channels:\u003c\/strong\u003e 2\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRevolution speed:\u003c\/strong\u003e 500 to 200 rpm (CLV)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eScan velocity:\u003c\/strong\u003e 1.2 to 1.4 m\/s, constant\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eData Read Principle:\u003c\/strong\u003e Non-contact optical pickup\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLaser Diode:\u003c\/strong\u003e GaAlAs (double hetero-junction visible-spectrum semiconductor laser diode), Wavelength: 667 nm\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTransport Outputs COAXIAL Format:\u003c\/strong\u003e IEC 60958 compliant\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOPTICAL Format:\u003c\/strong\u003e JEITA CP-1212 compliant\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDigital Inputs COAXIAL Format:\u003c\/strong\u003e IEC 60958 AES-3 compliant, Suitable cable: 75-ohm coaxial digital cable\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOPTICAL Format:\u003c\/strong\u003e JEITA CP-1212 compliant, Suitable cable: JEITA standard optical fiber cable\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUSB Format:\u003c\/strong\u003e USB 2.0 Hi-Speed (480 Mbps) compliant, Suitable cable: USB 2.0 cable\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSampling Frequencies COAXIAL:\u003c\/strong\u003e 32 kHz to 192 kHz (16 to 24 bits, 2-channel PCM)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOPTICAL:\u003c\/strong\u003e 32 kHz to 96 kHz (16 to 24 bits, 2-channel PCM)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUSB:\u003c\/strong\u003e 32 kHz to 384 kHz (16 to 32 bits, 2-channel PCM), 2.8224 MHz, 5.6448 MHz, 11.2896 MHz (1-bit 2-channel DSD) (11.2896 MHz: ASIO only)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eD\/A Converter:\u003c\/strong\u003e 4MDS principle\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 0.7 to 50,000 Hz +0, -3.0 dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTotal Harmonic Distortion:\u003c\/strong\u003e 0.0008% (20 to 20,000 Hz)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSignal-to-Noise Ratio:\u003c\/strong\u003e 119 dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDynamic Range:\u003c\/strong\u003e 116 dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChannel Separation:\u003c\/strong\u003e 113 dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOutput Voltage and Impedance BALANCED:\u003c\/strong\u003e 2.5 V, 50 ohms, balanced XLR type\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLINE:\u003c\/strong\u003e 2.5 V, 50 ohms, RCA phono jack\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOutput Level Control:\u003c\/strong\u003e 0 dB to -60.0 dB in 1-dB steps (digital)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePower Requirements:\u003c\/strong\u003e 120\/220\/230 V AC, 50\/60 Hz (voltage as indicated on rear panel)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e 11 W\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMax.
