9i-AD"Black Gold Ultimate Model"

. The 9i-AD series media player adopts the US Marvell's 88DE3010 Blu-ray solution as the main control and has high-definition video function. Because of the marvell qdeo technology, the video quality is very good, and it is in the leading position among similar products. In addition, because the internal high-end audio DSP is used and the multi-channel and dual-channel are independent, the audio performance is also very powerful. Cen.grand redesigned the chip clock architecture to give the DSP the ability to receive an external clock, the "independent audio dual clock" architecture, making the 88DE3010 a high-performance audio and video digital player solution. Cen.grand first proposed this architecture and achieved productization. In 2011, the first product 5i-A using this solution was launched.

Product description

     The 9i-AD series media player is the high-end player model of the Cen.grand product line. Originally released is the 9i-AD standard version, followed by the 9i-AD black gold version, 9i-AD black gold ultimate version.

 

     The 9i-AD series media player adopts Marvell's 88DE3010 Blu-ray chip as the main control and has video function. Because of Marvell's unique qdeo technology, the video quality is very good, and it is in the leading position among many Blu-ray solutions. In addition, due to the use of high-end audio DSP, and the multi-channel and dual-channel are independent, the audio performance is also very strong. We have redesigned the chip's clock architecture to give the DSP the ability to receive external clocks. This architecture is known as the "independent audio dual clock" architecture. Cen.grand first proposed this architecture and achieved productization. In 2011, the first product 5i-A using this solution was launched. The following figure shows the architecture of the 9i-AD Black Gold Ultimate version:

 

 

 

 

     9i-AD can play Blu-ray movies, can output 7.1-channel audio through HDMI interface, support Blu-ray navigation, playback of multiple video format files, 3D, etc. The audio supports wav, flac, ape and other music formats, and the sampling rate supports PCM192 and DSD64. The built-in hard disk supports 2T capacity, the external mobile hard disk supports up to 1T capacity, and can also be connected to the hard disk array through USB, and the capacity is not limited. The speed of the network card is 100M, and the video in the LAN can be played through wifi or wired connection.

 

     Designed to follow the high-end HiFi standards, device selection and circuit design are all based on audio performance. The DAC uses two WM8741 chips, which are typical British-style chips with a rich musical flavor. The analog output of the 9i-AD is a discrete device structure. The 9i-AD has an independent DAC function and can be used as a stand-alone DAC. The audio output is available in RCA and XLR.

 
 

 

      In addition to its precise design, the 9i-AD series media player is also well-positioned for audio style adjustment, which is why it is highly recognized in the HiFi market. 9i-AD series media players are generally used as the main source of home audio and video systems, and can replace cd, sacd, and Blu-ray players. In addition to getting hifi audio, you can use it to play Blu-ray concert videos. Blu-ray concerts have a lot of resources, and the 9i-AD Black Gold Ultimate Edition is the only product that unifies hifi audio and high-definition video.

 

      Compared with the "9i-AD black gold version", the "9i-AD  Black Gold Ultimate Edition " mainly has the following improvements:

       1. The main control circuit board is redesigned, the function of up-clocking to 4K is cancelled, and the audio-related part is greatly optimized.

       2, the digital audio circuit has made a big improvement

       3, added ESATA high-speed external storage interface

       4, the display is upgraded to a high-definition screen, the interface is more beautiful

       5. The analog circuit is completely redesigned. The sound is completely different from the 9i-AD black gold version, and the sound quality has a European style.

 

 

    The main highlights of the 9i-AD  Black Gold Ultimate Edition :

       1, support 24K/192Kz PCM

       2, support DSD64 DSD ISO, dFF\DSF file playback (non-compressed)

       7, with spdif coaxial input, can be used as an independent DAC

 

 

    Output interface on the 9i-AD  Black Gold Ultimate Edition :

       1, XLR analog balanced output interface

       2, RCA unbalanced output interface (strongly recommended)

       3, 5 hifi digital output interfaces: 2 RCA, fiber, BNC, AES

       4, 2 AV spdif digital output interface: fiber, RCA

       5, 1 set of spdif input (RCA)

       7, 2 * USB input

       8, 1 * HDMI1.4 output

       9, 1 * ESATA input

     10, 1 * 100M network port input

     11, 1 * YPbPr output.
