Integrated power supply<\/strong><\/p>\n

With separate analog and digital transformers and SiC Schottky diode based rectification,
\nthe DSP-04 EX borrows from its high-end cousins in the lineup to boast an equally robust power supply.<\/p>\n

Superlative internal architecture borrowed from high-end models<\/p>\n

DSP-04 EX uses the same low phase noise TCXO as that of DSP-02 EX. In addition, the CPU,
\nclock generator circuit, and analog power supply are identical to those used in the DSP-02 EX,
\nfollowing in the footsteps of its high-performance, no-compromises architecture.<\/p>\n

Next generation audio for high-resolution and DSD.<\/strong><\/p>\n

Audio network player is a new style of audio.<\/p>\n

So-called “High-Resolution” music sources with sound quality superior to CDs are now being sold via download.
\nBy using network player, you can enjoy sound sources stored on a NAS (Network Attached Storage) or a PC,
\nusing a tablet device as a remote control, just like a Juke Box. You can easily search tracks by genre, artist name, etc.
\nYou can also enjoy viewing album art on the screen of your tablet device.
\nYou can check a track title, an album name, and an artist name on your tablet’s screen
\nand on the display of the network player as well.<\/p>\n

Network player is truly the next-generation of audio,
\nwith high sound quality, high reliability and easy operation.<\/p>\n

The SFORZATO network player plays not only high-resolution PCM, but also DSD.
\nIt plays all high quality sources with outstanding sound quality.
\nAll you do is choose the tracks on your tablet. After that, just sit back and enjoy.<\/p>\n

ES9018S for D\/A conversion<\/strong><\/p>\n

The ESS DAC no longer relies on internal jitter removal, running in perfect synch with signal input.
\nThe high-fidelity clock and scrupulously arranged clock wiring and architecture ensure perfectly synchronized, jitter-free audio.<\/p>\n

Robust power supply<\/strong><\/p>\n

With distinct digital and analog power sources, high capacity transformers,
\nand the high-speed, low noise SiC, the devices drive high power for deep, rich music playback.
\nThe dedicated DAC’s analog 3.3V and 1.2V sources feature discrete, feedback-based power
\nwith a high-speed, low noise error amplifier, while the analog output uses a discrete,
\nfeedback-less power source.
\nOn the digital side, multiple hi-fi LT1763 LDOs, courtesy of Linear Technology, regulate POL (point of load).
\nEach integrated circuit works in a discrete fashion without interference from the others, utilizing
\n100% of their capabilities and ensuring jitter-free playback.<\/p>\n

Noise suppression<\/strong><\/p>\n

Using a multi-layer circuit board with a wide top \/ bottom grand plane allows the majority of digital signals to be arrayed within the mid-layers.
\nHeavy shielding reduces noise to the utmost.
\nNon-magnetic noise absorbing sheets and shield casing cover noise generating components like the CPU,
\nwhich provides network connectivity, and the clock circuit area, achieving robust noise suppression. DSP-04 EX use 6-layer boards.<\/p>\n

10MHz Clock input<\/strong><\/p>\n

All products in the DSP lineup feature a clock generator with outstanding low phase noise.
\nIf you wish to enjoy still further fidelity, the units come equipped with a 10MHz master clock input.<\/p>\n

Software updates<\/strong><\/p>\n

The digital controller is driven by an ARM11 microcomputer and FPGA.
\nNetwork-based software updates allow your device to always enjoy the latest features and functionality –
\nthis means our products continue to evolve even after you’ve purchased them.<\/p>\n

Supported formats<\/strong><\/p>\n

Not only is PCM supported, but native DSD playback is also available.<\/p>\n

PCM:<\/strong><\/p>\n

AIFF, WAV, FLAC, Apple Lossless and WMA Lossless
\n44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz \/ 16bit, 24bit
\n(WMA Lossless: 44.1kHz – 16bit only)<\/p>\n

DSD:<\/strong><\/p>\n

DSF, DIFF 2.8MHz, 5.6MHz, 11.2MHz.<\/p>\n

Support for future formats will be added by way of software updates.<\/p>\n

Master Clock Generator : PMC-02 EX<\/strong><\/p>\n

Phase noise performance that exceeds that of Rubidium clock generators<\/p>\n

The PMC-02 EX utilizes an OCXO component that guarantees,
\nunder the worst condition, phase noise of -100dBc\/Hz @ 1Hz.<\/p>\n

\"\"<\/div>\n

 <\/p>\n

\"\"<\/div>\n

Generous power supply<\/strong><\/p>\n

The PMC-02 EX also makes use of a high capacity toroidal transformer
\nand discrete analog power source composed of a high-speed, low noise SiC Schottky diode.<\/p>\n

The master clock is the life of digital Audio.<\/p>\n

All digital audio devices operate using the clock as a standard when they convert digital signal to audio signal,
\nso the quality of the clock greatly affects the quality of the sound. It is the very pulse of digital audio.<\/p>\n

Absolute precision is not the performance digital audio demands of the master clock.
\nThe highest precision tuning meter (Strobe Scope)used by musical instrument makers has an accuracy on the order of 1\/10 cent.
\nOne cent is 1\/100 of a half tone (the musical interval between neighboring white and black keys on a piano).
\nIf you calculate the frequency, it is a precision of dozens of ppm.
\nThat level of precision can be easily obtained by any standard clock generator.
\nThe high fidelity generators used in normal high grade audio have 10 times that level of precision,
\nand there is no significant benefit in demanding any more precision than that.<\/p>\n

The clock performance needed by digital audio is phase noise (the frequency components outside of the generating frequency
\nthat shouldn’t be present, in other words, impurities), which affects jitter. The clock, which governs all operations of digital audio,
\nshould not be able to correctly restore audio, if it is contaminated by noise.
\nUsually clock signals are supplied through the PLL circuits to the D\/A converter.
\nThe PLL works as filter, so any noise with a frequency that is significantly different from the generating frequency
\nof the clock generator can be removed. In other words, the noise from frequencies other than the generating frequency is
\ndetermined by the performance of the circuits behind it.
\nHowever, noise with a frequency that is very close to the generating frequency (neighborhood phase noise)
\ncannot be removed by the filter, so when it is converted by the D\/A, it becomes jitter. Just imagine,
\nyou can easily separate a pebble from a gain of sand with a sifter, but you cannot use a sifter to separate one grain
\nof sand from another only slightly larger grain of sand.
\nTo suppress neighborhood phase noise, you have no choice but to use a clock generator with little neighborhood phase noise.<\/p>\n
