Please note:
1, The product even had burn in over 100 hours before shipping, we are suggest user let it burn in another 300 hours. The built in clocks even need 1000 hours to finished burn in.
2, The product can always power on . ( In the thunderstorm days please shut it down and disconnect the computer and TV connect if exist.)
3, Connect the cable on the product, please power off it and the DAC.
4, Don't connect the very heavy USB cable and HDMI cable ,while connect the cable please take care , don't break the sockets on the unit.
5, The regenerative power supply need around 5 seconds to start , so push on the power switch, the display will light on 5 seconds later .Power on the product must had more than the half minute after last power off .
6, The product built in the voltage select switch, can change the power supply if necessary (It has high voltage inside, only can technician can open it ).
7, Must be notice : If have not plan to update the Amanero firmware , must can't touch the update port switch , otherwise the Amanero firmware be clean and the product can't work !

Button feature:
Leftmost button :
          Power On/ Off .
"Setting" button :
          Push once to go into the setting menu, the display will be flashing. Settings can then be modified.
"Selector" button :
           Push to toggle between the external and internal clock when the display not flashing .
           While the display flashing, push this button to change and set the settings.

Display feature:
Digit on top:
         Input signal sampling rate indicator; 44.1, 48.0,88.2, 96.0, 176, 192, 352 and 384 are for the PCM formats, while 064, 128, 256 and 512 are for the DSD formats.
Menu page 1 (Default display menu page 1):
Leftmost digit on bottom:
         External/internal clock, "I" indicates the internal clock is selected, "E" indicates the external clock .When the clock connected, the right bottom of this digit will light up a dot, that can go into the setting menu to set the DI-24HE work with external clock. Otherwise, the external clock cannot be selected.
          If the external clock lose power, or the cable has bad connect , even though select the external clock, the "E" will become "I" (Switch back in inside clock) automatically for avoid output noise.
2nd digit on bottom:
         Select 10MHz input clock from 50 or 75 ohm port. "5" indicates the 50 ohm port, "7" indicates the 75 ohm port .
         Only both ports have connected that can select, if only connected one port, no matter of the selection but the Di-20HE will auto switch to the connected clock source.
3rd digit on bottom:
         Select output clock from external/internal clock, "I" indicates the internal clock is selected, "E" indicates the external clock .When the clock connected, the right bottom of this digit will light up a dot, that can go into the setting menu to set the output from the external clock.
4th digit on bottom:
          "P" (Parallel) means the signal will be processed internally by the 32 bit (PCM) or 64 bit (DSD) parallel mode . "S" (Serial) means the signal will be processed by the serial mode.
5th digit on bottom:
           "d" (dim ) means the display will automatically shut off after around 10 seconds if no buttons are pushed. "b" (bright) means the display will remain on.
Menu page 2 (When push "Setting" button repeatedly ,when the 5th digit on bottom flashing, push "Setting" button one more time that go into the menu page 2) :
Leftmost digit on bottom:
         "n" (Non Swap) means the HDMI outputs DSD with left and right channels following the Audio-gd definition . "S" (Swap) means the DSD left and right channels are inverted .
2nd digit on bottom:
         "1" means the PCM over HDMI i2s output follows Audio-gd's definition . "2" mean the pins definition follows other standard . (Read below for details ).

Rear plate connectivity :

AES/EBU OUT ：
        AES/EBU output connector（3.3VPP @ 110 Ohm）。
S/PDIF OUT ：
        Coaxial output connector, with built-in silver wire isolation transformer. (0.5VPP @ 75 Ohm）.
Multiduty -OUT ：
         10MHz clock outputs (>9BDm at 50 ohm)
IIS OUT ：
          IIS signal over HDMI output (3.3V LVDS @ 110 Ohm). It only can work with DACs using the exact same pin definition. It can NOT work with mainstream audio/video devices featuring HDMI inputs, and connecting the DI to such devices could damage it, in which case the warranty will not cover the repairs.
Multiduty IN ：
        75 Ohm external 10MHz clock input (0.3VPP -3VPP @ 75 Ohm)
INPUT 10MHz ：
        50 Ohm external 10MHz clock input (0.3VPP -3VPP @ 50 Ohm)
INPUT USB ：
        USB audio input（USB2.0/USB3.0）。
UPDATE PORT 10 pins port :
       To connect the Altera Blaster and proceed with an FPGA firmware update from Windows, using the Altera programming software. These updates are meant for upgrading the functionality and/or sound quality .
UPDATE PORT switch :
        For updating the built-in Amanero module's firmware through the USB input.
        Must be notice : If have not plan to update the Amanero firmware , must can't touch this switch , otherwise the Amanero firmware be clean and the product can't work !

HDMI i2s output definition setting (In the setting menu page 2):
HDMI output mode 1:
       The 1st display element indicates "n" (Non swap) and the 2nd indicates "1" (In the setting menu) : i2s out follows the Audio-gd i2s definition.

HDMI output mode 2:
       The 1st display element indicates "n" (Non swap) and the 2nd indicates "2" (In the setting menu) :
