 DSD128 / PCM384K ，， AK4495SEQ This product uses an analog power supply audio DAC AK4495SEQ top core design， the top chip AK4118 audio-specific mediation as coaxial and fiber optic signal reception， full of deep software control optimized to support the highest standard of using a separate Group rectifier filter， low-noise high-speed Category A shunt regulator power supply， power supply voltage of 7 volts， the biggest feature of this power supply is low noise， low internal resistance， high speed， out of the sound field deep black background， dynamic sound field， excellent knot strength，
    Product features are as follows:
    1. A simple three-button controlph-ilips
    2. Provide full-function infrared remote control reception， use Apple Remote remote control， (without remote control， please buy their own)
    3. Provide 3 inputs， coaxial， fiber optic， USB (or IIS / DSD input)
    4. With LCD display
    5. Support IIS / DSD straight into AK4495SEQ， PCM / DSD by DSD_ON signal switch automatically identify and display the corresponding PCM or DSD， and the corresponding sampling frequency
    6.0-59 volume level control extremely delicate， no jump， you can replace the previous stage to achieve volume control
    7. Volume graphical and digital display， clear and intuitive
    8.5 Group filter settings
    9. The on-board microcontroller MCU， you can not connect the LCD display panel，
    10. The power amplifier uses discrete components Jiang Sheng regulator circuit
    11.LFP section does not use a coupling capacitor， the sound is more HIHF.
    12. The analog part VISHAY MMA0204 resistance， top Ni-kon KZ， KW electrolytic capacitors and Phi-lips Blue Shell capacitance tuning， sound real and natural， powerful bass loose
    13. You can use matching XMOS U8 module (This product does not have USB module， available separately)， to achieve the highest standard of DSD128 / PCM384K Play
    14. automatically save all user settings

IIS / DSD input connection




Display panel keys Description:
    MENU key: short press to switch AK4495S filter parameters， long press (more than 0.5S): Switch the input channel
    UP key: short press to increase the volume， long press (more than 0.5S): continuous increase volume
    DO key: Short press to reduce the volume， long press (more than 0.5S): Continuous decrease the volume
    USB module switches: the volume to "0"， short press MENU key to switch

Can be installed directly in Italy Amanero USB card for PCM， 44.1KHz-384KHz / 32Bit， automatically displays the corresponding sampling frequency， use the card does not support hardware solution DSD， (Note: Use Amanero USB card can play normally DSD64 / DSD128， but there will be a larger operation， switching noise， which we believe can not use this card "Support hard solution DSD"， pictures are for reference， this product does not contain the USB module， the shop did not sell this card， please purchase separately)


 
XMOS U8 module is installed in the decoding board supports PCM， 44.1KHz-384KHz / 32Bit， DSD64 / DSD128 (Pictures for reference， this product does not contain USB module， available separately)
