    Components

     

     

    1. Class A balanced Structure

     

    The part of headphone amp,GDX,designed absolutely four groups of amplifier,provided balance amplification

     

    drive,and the output grade was in a state of class A .After testing many times ,we choose the combination of

     

    OP275 and LME 49710 matching class A output.And that benefit many headsets drive.Adding to using

     

    classic relay to control the volume adjuster system of resistance transition,the part of headset was not the

     

    short stab.

     

     

     

    2. USB Interface

     

    GDX use asynchronization states XMOS U8 mode to handle the USB signal macthing with special  XMOS

     

    clock system  ,supply XMOS with extemely low digital noise and precise clock signal.GDX also provide

     

    S/PDIF signal output as high quality USB to S/PDIF.

     

    SUB Output high support PCM:32Bit/384KHz;DSD64/DSD128.

     

     

     

     

     

    3. D/A Framework

     

    GDX use AK4118 as S/PDIF signal output demodulation,supply low JITTER ,IIS signal to the next

     

    grade.S/PDIF signal output high support 24Bit/192KHz.

     

    Use AKM AK4495S as D/A chip,we designed for super high speed ,low noise power supply system ,provide

     

    the best running environment. We designed low distortion,low noise,high dynamic range analog output

     

    circuits,and to achieve a perfect state .In order to achieve a better sound we select component

     

    carefully,Panasonic ECHU resistor  ,Murata COG,  VISHY resistance, NEC signal relay and so on.

     

     

     

     

     

    4.Perfect I/O Port

     

    Through the selection of the panel the GDX can be used as a pure digital decoder, which isa high-quality

     

    fixed-level output decoder. At the same time GDX provides 80 level adjustable volume control, can be used as

     

    pre-output level transferring professional active speakers. Perfect digital input: USB, optical fiber, AES,coaxial

     

    digital signal input, improve a group of USB to S/PDIF digital signal output, can be used as USB digital

     

    interface.

     

     

     

     

     

    5.Specially developed clock system

     

    A special Super low phase noise SPXO low phase noise audio crystal oscillator is used to provide ultra-low

     

    phase noise clock signal for the whole machine. A complete digital signal processing system is designed to

     

    provide FIFO,DE-JITTER processing for various IIS signals. The whole digital system works at a high

     

    frequency, so we choose up to 14 sets of regulators for ultra-low noise power supply at all levels, as well as

     

    an optimized four-layer PCM LAYOUT.
