Please note:
       
 This product applies the latest power technology. Therefore the working temperature has dropped significantly compared to the previous generation products. This allows leaving power on over the long term.
        This product is burned-in for at least 300 hours before shipping.
        We recommend burning it for an additional 300 hours for best results.
        The quickest way to complete the burn-in of this product is to play music continuously.
        Do not immediately power on the unit after powering it off. Wait for at least 30 seconds.


Normal working state display:

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.
Leftmost digit on bottom:
        
If update the EC firmware to allow external 10 MHz clock input, 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 DAC work with external clock.( for details, read below ).
2nd and 3rd digit on bottom:
        
Oversampling display, could be set to NOS modes include N0 and N1, also the OS modes include O2,O4 and O8 .
4th digit on bottom:
          The turnable sound flavor simulate .
5th digit on bottom:
         
Input channel indicator, either 1,2,3,4,5, 6  ( for details, please read below ).

Button functions:


Leftmost button: Power On or Off.
Left button on right side: (Only available while user want to change the set  feature .)

        Push the left button once, the leftmost digit of bottom will blink, which indicates it is selected. This allows changing the corresponding setting. Push the right button to select the desired value. While the display is still blinking, push left button again , the next digit to the right will be selected and blink.
         While the rightmost digit of bottom is blinking, push the left button one time, quite the set menu and back to the normal state.

Right button on right side: (Mulriple functions.)
         While the display is in normal state (not blinking), it allows selecting the input source in decreasing order. One of the following will be displayed:
"1 - AES", for the AES/EBU digital input;
"2 - BNC", for the BNC coaxial digital input; (If update the EC  firmware, the 2-BNC is for the external clock input .The external clock output impedance must be 75 ohms, the supported output level range is 0.7-3.0V and a 50-ohm BNC cable must be used.)
"3 - RCA", for the RCA coaxial digital input;
"4 - OPT", for the optical digital input; (For the best sound quality , R-27HE optical input sensitivity rigorous follow the worldwide standard, it may can't work well with some models TV, TV box or game box  optical outputs if weaker than standard.)
"5 - IIS", for the HDMI-IIS digital input; (The HDMI-IIS need the source HDMI-IIS output has the same pin definitions for compatible and work. It can't work with the TV or computer standard HDMI output .)
"6 - USB", for the USB digital input. (For Windows , the computer must install the driver for recognize the device. Mac, Linux, IOS and Android don't need driver install.)


Setting values

The leftmost digit on bottom: External clock select
       
I (Internal) : Selects the internal clock
        E (External) : Selects the external clock
        The external clock selection is only possible after a successful clock connection is made, otherwise the display will show "Fail" on an attempt to select it.

The second and third digit from the left  on bottom: OS and NOS mode select.
       
While working under oversampling (OS) mode, the lower the oversampling level is, the warmer the sound will be. While working under non-oversampling (NOS) mode , the sound even more warmer and smoother. The possible values are:
        N0 : New NOS mode.
        N1 : Basic NOS mode.
        O2 : 2X oversampling
        O4 : 4X oversampling
        O8 : 8X oversampling

The 4th digit on bottom: Simulates the sound of a turnable
        S (Simulate) : Activate the phono simulation feature, and we recommend to set the DAC on OS2, NOS0 or NOS1 mode for best results.
        n (Non-Simulate) : Disable the phono simulation.

The 5th digit on bottom: Display auto-dimming setting
        D (Auto Dark) : Enables the display's auto-dimming; the display will dim 10 seconds after the buttons are left untouched, only keeping a LED bar lit to indicate the unit is turned on. As soon as a button is touched, the display will turn back on.
        L (Light) :  Disables the display's auto-dimming, the display will remain on at all time.  


HDMI definitions : (Apply HDMI transmit the IIS signal, the pin's definitions must exact same , and not promise compatible with other brands)

         Note that this product does not require the source MCLK signal but if present, it will simply be discarded.

UPDATE PORT switch :
        For updating the built-in Amanero module's firmware through the USB input.
Please note:
        Don't touch this switch when the product is powered on unless proceeding with an Amanero firmware update, underwise you will be forced to proceed with an actual update, as the firmware will have been erased.
