As you can see, 9i-AD system clock MCLK differs from other players, clock source directly to the DAC transfer clock signal. Ordinary player, you must use the internal division of DSP MCLK, cannot be synchronized. 9i-AD rely on synchronous technology, DSP and DAC two different systems are able to directly use the clock source, gives the DAC section of clock jitter of clock source of standard 9i-AD high performance, comes from this.
Music performance: balancing the atmosphere, good, Quality open atmosphere, showing high density, large hi-end of the sound field characteristics
Some players emphasize the use of a low jitter crystal oscillator, but if the DAC is isolated from the system clock MCLK chip, low-jitter crystal oscillator into the clouds again. SOC chips caused by jitter, crystal oscillator strengths have been exhausted. Therefore, low-jitter crystal oscillator to play a role, but also how to apply it to. 9i-AD gives the applied example.
9i-AD what a comprehensive player, DA design is critical to performance. 9i-AD century gray praised dual WM8741 programme builds on 9i-60s design, analog output using discrete structures, light feedback high current design, out of the same ' operation burst out. 9i-AD using the Wolfson programme in the industry obtained the authorization of Wolfson, century Gray's digital products are available on the Panel using a special mark Wolfson.
Century in grey HIFI sours, rely on professional equipment systems, 9i-AD defines what digital player worthy of reference.
Same as the 5i-AD, 9i-AD still has the top 3 Blu-ray video, why the addition of this feature, digital media player 9i-AD became powerful 3D Blu-ray video capabilities, QDEO image, deservedly became a HiFi audio and video products.
▇ Sound quality of the Blu-ray music ▇
Introducing 9i-AD, it will have to introduce Blu-ray music.
With Blu-ray audio carrier has two forms, one is made of blue disc material CD discs, called 'blue-spec CD' in English, it is, in essence, a CD, with an ordinary CD player. Another is a real Blu-ray discs, but there is no video (or picture), audio only, playing only on the function of Blu-ray players, ordinary CD does not play, its English name was 'blu-Ray audio', or 'Pure audio Blu-ray'.
Currently, pure music Blu-ray discs are commonly known as what ' Blu-ray CD', such properties exist conflicting versions. Is essentially different from the Blu-ray and CD formats, Blu-ray Blu-ray storage technology is used, a shorter wavelength, CD format using a red light, the longer wavelengths, they are not compatible, so the ' Blu-ray CD' this view is not standard. Century gray will no longer be used in future campaign ' Blu-ray CD' the term unification in Chinese ' Blu-ray music ' replaced English with Blu-ray audio, or pure audio Blu-ray disc. When the actual specific discs can be called ' Blu-ray disc of music ', or ' Blu-ray disc of music '.
Blu-ray music (Blu-ray audio) since recording began Hou get of data, to zhihou of disc made, are to data file of form into, coding is with no compression of LPCM format, no compression link, more no like CD machine as coding Hou to disc pit points physical length to records data and clock of process, so Blu-ray music disc actually is a Zhang data disc, which of file format why M2TS, can in Windows Xia copy. Is this pure file process, Blu-ray music disc (Blu-ray audio) into why has real meaning Shang of mother with, plus Blu-ray disc up to 50G of save reserves, can capacity Xia more tracks no compression of high sampling signal, in various audio format in the get has highlight of advantage, this advantage in high performance of Blu-ray music play device (5i-A/AD) appeared Hou, get has user of consistent certainly, was recognize why is more SACD of better audio format. 9i-AD after market, high-quality Blu-ray music programs will be more fully shown, fans will experience the Blu-ray music (Blu-ray disc audio) New audio format of the sound quality leap.
It is important to note: Blu-ray player/Blu-ray products is why video and positioning at the beginning of the audio structure did not design according to HIFI standards, based on the needs to adapt conditionally available, whether imported or domestic products is true. At present, the only century Gray's Blu-ray products (including Blu-ray disc, Blu-ray player, HD) is the use of HIFI audio structures, architecture to the design of the clock system in full accordance with the CD. At this stage the only century gray Blu of Blu-ray products, reinstate the player is real HIFI products.
Current Blu-ray music programs are few, why major publishers NAXOS companies and Norway 2L. This year, Germany established record companies, such as DG company stepped in Blu-ray music release, a year or two there will be more programs out on the market today.
▇ Complete music format support ▇
9i-AD perfect music playback, support 24/192 the following WAV, FLAC, APE and other mainstream audio formats, support for CUE. Also supports DTS formats CD, you can meet the requirements of music appreciation.
▇ Independent decoding ▇
9i-AD in addition to a native playback function, also have independent decoding functions, why can a decoder to use. Why century gray standard decoder programme: United Kingdom Wolfson WM8805+ dual WM8741 programme software.
WM8805+ double WM8741 only century gray completed BUG-free depth of development, the current receive low jitter WM8805 DA WM8741 combined with the simulation. Century gray is Wolfson authorized enterprises, Digital products Can using a special mark Wolfson on the Panel.
9i-AD decoding WM8741 design, analog output why century gray carefully developed discrete semiconductor circuits. Compared with the op-amp output, because of there is no deep feedback amplifier, Quality open atmosphere, showing high density, large hi-end of the sound field characteristics . Native decoding consistent with the century gray 9i-60s high-end audio decoder, is a century 2013 iconic grey HiFi products.
Following Board '▇' Button for 3 seconds, and blue indicator lights to the left of a button panel, machine into independent decoding functionality. According to the sampling of the input signal, Left side of the keypad On the lower three LEDs will be lit. If the input signal in order to 192k/176.4k, above the light, input in order to 96k/88.2k, led, input in order to 44.1k/48k, the following indicator lights.
Independent decoding only used coaxial digital input ports. Is used to the attention: after booting the first native playback, native mute lift, independent decoding can be achieved if a boot directly into independent decoding will be silent.
▇ High-end video features ▇
9i-AD also has powerful video features, with Marvell QDEO technology and Blu-ray 3D capabilities, you can play 3D Blu-ray the original disc and ISO file, and next-gen audio through HDMI output.
Video using Marvell 88DE3010 scheme, equipped with firmware currently 3010 package complete. Highlights of the video part is: due to the sophisticated technology of hardware, 9i-AD on the picture quality and HD with programmes on the market has some advantages over . But compared with its audio performance, 9i-AD video feature is not prominent.
9i-AD because of the high-end audio and video features, it is not only the choice of music enthusiasts, but also of choice for both audio and video enthusiasts.
▇ Good UI interface and Ipad/Android Control function ▇
9i-AD on the main panel with a 7-inch display, can display playback information, you can also display video, his appearance is consistent with HDMI output. This design greatly facilitates users who listen to music. 9i-AD UI interface will continue to improve in the future.
If you have a local area network, you can 9i-AD via a wired or wireless network, you can use iPad, Android PAD, ipahoe, Android smart phones, computers and other IT equipment to control playback, which is very convenient.
▇ Support NFS/DLNA ▇
By NFS/DLNA play 9i-AD local area network resources on the network. NFS can play the big stream of 3D Blu-ray movie, DLNA can play audio files. Network broadcast sound quality difference with local broadcasts can be heard, lovers can try.
▇ Professional HIFI audio architecture ▇
Century gray and conditionally available for different reason century is one of gray's products from the infrastructure, all follow the HiFi product design specifications.
Architecture the following figure of 9i-AD. high-performance audio dedicated DSP from Philips, working frequency 500MHz. Philips's achievements in digital audio is a flag and HiFi Chu up. 9i-AD audio dedicated dual-clock and combinations form a rational structure for digital audio playback.
