Differences between CX100 and CX200:Relatively speaking, the CX200 has a large exterior size and a built-in power supply, making it suitable for rack use.The CX100 is more exquisite and compact, with a wider use scenario. Due to the split design of the host and power supply, there is a wide range of power supply selection. Many buyers even use the CX100 host for vehicle use. If matched with the P100 power supply (non-standard) suit, the upper and lower stack can be used for desktops, and the left and right can be used for standard rack seats.Since P100 can have a built-in hard disk, for users who use mobile hard disks, a host + P100 on the desktop is enough to avoid plugging in a hard disk stand or hard disk box that is not suitable for appearance.In addition, the CX100 player adds a configurable linear LVDS IIS output, and the CX200 is a TTL IIS output. When connecting with the decoder using IIS, you must select the same standard interface; there is no essential difference in sound quality and control between the CX100 and the CX200.

1. Product Overview: 

     CX100DA digital player is a HIFI -level audio product product. The player reads the digital music or parent file on the U disk/USB mobile hard disk and SD card.Later, the output high -quality digital signal and the analog signal required by the amplifier ear mount can be played by player panel, infrared remote control, mobile phone and other methods to play the whole process, and at the same time display the current playback and status information.

CThe X100 digital player is equipped with the second generation of hardware and software platforms dedicated to audio playback. Compared with the large number of public version of the digital player product in the market, no matter the sound quality, operation control, and product stability are no longer at the same level. After all, the public versionThe plan needs to consider the commonability of various products, which cannot be "specializedNote"Digital music playback, even the player's startup time cannot be accurately controlled, usually ranging from several seconds to tens of seconds. If it is a dedicated architecture, you can immediately enter the state to be played.

     After having a stable and efficient work platform, we have invested a lot of energy to improve the product's sound quality.Including the research on the FPGA core processing algorithm and manipulation mechanism of the digital player, the control of the working state of the digital player is no longer satisfied with underlying programming and single-thread programming, and has been accurately and refined to the clock level, so that the reading and streaming of digital audio files can be more accurately controlled.In addition, for the core audio processing links, the decoding, debounce, reorganization, IIS, S/PDIF data synthesis output, etc. of the audio code stream are all integrated into the FPGA and completed in a unified manner. The parameters and processing algorithms at all levels will be continuously optimized, and finally the firmware upgrade will be upgraded to achieve continuous improvement in sound quality.

     In terms of control, thanks to the efficiency of the professional playback platform, you can enter the state to be played by turning on the computer.In addition to conventional panel button control, it has a high sensitivity infrared transmission and reception system, which ensures a remote control distance of several meters and is extremely wide in the remote control angle.For longer-distance control, we have developed WIFI control software for mobile phones with Android and Apple IOS dual-platforms to realize a series of operations such as browsing, selecting and playing a large number of tracks in digital players. The smoothness and compatibility are far better than cheap methods such as web pages and DLNAs that are commonly used on the market.In addition, the WIFI components in the digital player have flexible networking methods, which can be used as a hot spot (AP) to connect the mobile phone directly, or as a wireless client (STATION) to participate in networking, so that the mobile phone control does not affect its own network function.

     The player uses a unique file management mechanism. In addition to supporting multi-level directory access, there is no upper limit on the number of folders and audio files in the memory. Even under normal playback, audio files in the memory can be browsed smoothly.It also has an advanced track retrieval algorithm. For massive audio files (audio files with T capacity) of large-capacity USB hard drives, whether they are connected to the digital player for the first time, or if the files are added or deleted after use, they are plug-and-play, and there is no long scanning waiting time.

    In addition, we have femtosecond and Bluetooth components as optional configurations.The Flyingkllo hour is commonly known as the low -phase noise clock. The clock is equivalent to the command of a band in the digital music player circuit.Cchd957.For Bluetooth, many enthusiasts may have doubts about their sound quality, but with the advancement of Bluetooth technology and our unique FPGA processing technology to guarantee, I believe it will make you refreshing, and you can support any music playback software push on mobile phones or tablets.DLNA can only be compatible with some software.

2. Product sound quality:

     It still inherits the consistent tuning style. The digital processing link does not have any rendering, and truly restores the original information of the audio file to avoid cross-tuning with the backend device and tuning aliasing. Therefore, when using only the digital part, the sound quality is basically determined by the backend device. The better the backend is, the better the sound can be, and the style of the backend is, and the style of the backend will be.The CX100DA built-in decoder uses HIFI-level AK4495SEQ decoding chip. The chip itself has done a very good job in sound equalization and high and low sound extension. On this basis, we fine-tune the sound base in the simulated part of LPF to achieve softening of the tone (commonly known as warm sound), so that both the musical instrument and the vocal playback can be taken into account. 

3. Design details

     In addition to the pursuit of sound quality, we also pay attention to the design and process requirements of the product. The shell uses a customized model full aluminum process, which repeatedly adjusts the strict seams of each component.With a backlight button design, even at night, it is very eye -catching.The knob uses the classic 360 -degree rotation encoding switch. In addition to the volume control, it is also used as a menu option.The display part is expensiveThe imported 2.8 -inch OLED full color screen, its delicate display effect and the viewing angle feature close to 180 degrees far better than the conventional TFT display.

      The player is powered internally and uses the unique low-voltage power regeneration technology.Since the player needs to take into account the use of the on-board environment, the internal power supply processing has higher requirements than conventional playback equipment. Lead-acid batteries are generally used in the car as power supply. However, due to the impact of other on-board equipment, the noise and interference problems in the power supply are very serious (can be as high as 100mVpp, even the conventional mains switching power supply is only 50mVpp~80mVpp). We have tried various filtering, multi-stage LDO and other conventional power supply noise reduction methods, but they have never met our requirements.In this regard, we have begun to introduce the new technology of power regeneration. Although the complexity of power supply and design and debugging have increased a lot, the effect of interference noise suppression is very obvious. After multiple parameters and PCB wiring revision optimization, even in the harshest on-board environment, the noise power supply ripple can still be controlled below 2mvpp level, which is better than the conventional linear power supply index.In addition, due to the use of regenerative power supplies, the simulation part can easily obtain the required double and negative 15V low-noise dual power supplies. Compared with the positive and negative 7V or even single power supplies commonly used in desktop simulation parts, it has inherent advantages in audio dynamics and analysis.The guarantee of power supply quality lays a solid foundation for the final product to obtain good sound quality.
