to indicate the clock signal is detected ( for details, read below
).
The remaining digits:
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.
Button
functions：
Setting button:
Push the "Setting" button
once, the leftmost digit will blink, which indicates it is selected.
This allows changing the corresponding setting. Push the right
"Selector" button to select the desired value. While the display is
still blinking, push "Setting" again , the next digit to the right
will be selected and blink. Push the left "Selector" button to
select the digit to the left of the one currently selected.
Left "Selector" button:
In the standard edition , reserved for
future use
In the Update EC firmware
edition edition, while the display is in normal
state (not blinking), it allows selecting the Internal or
External clock selection
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.
While the display
blinks, the left "Selector" button allows moving the selection to
the left.
Right "Selector" buttons:
While the display is not
blinking, it allows selecting the input source in increasing order.
"1 - AES", for the AES/EBU digital input;
"2- BNC", for the BNC coaxial digital input;
"3 - RCA", for the RCA coaxial digital input;
"4 - OPT", for the optical digital input;
"5 - IIS", for the HDMI-IIS digital input;
"6 - USB", for the USB digital input.
In the standard edition edition, the IN2 BNC input is the BNC coaxial input .
In the Update EC firmware
edition edition , the
IN2 BNC input is the external 10MHz 75ohm input port, it need the
level 1-3V p-p, it can work with sine and square waves but recommend
square wave ,setting through the
below introduce
.
While the display is blinking, it allows changing the value of the
selected setting.
Setting values：
Important warning:
Before changing the settings,
the user is advised to lower the volume and to stop the playback.
To guarantee the best possible
sound quality, this DAC is without a muting function, therefore
unwanted sounds can occur while settings are modified.
After 5 seconds without pushing
buttons, the display will stop blinking; the user can then resume
music playback and raise the volume to the desired level.
The leftmost and
second digit from the left: Oversampling select
O (OS) : to select the oversampling
mode.
n (NOS) : to select the NOS mode.
While working under oversampling (OS) mode, the lower the oversampling level is, the
warmer the sound will be. The possible values are:
N0 : New configure
NOS setting.
N1 : basic NOS mode.
O2 : 2X oversampling.
O4 : 4X oversampling.
O8 : 8X oversampling
The 3rd digit: Simulates the
sound of a turnable
S
(Simulate) : Activate the phono simulation feature, and we recommend to set the DAC on
OS2, OS0 or NOS mode for best results.
n (Non-Simulate) :
Disable the phono simulation.
The 4th digit: reserved for
future use
The 5th digit:
Display
auto-dimming setting
A (Auto) : 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.
n (Non auto): Disables the display's
auto-dimming, the display will remain on at all time.
Setting examples:
1. Settings for most neutral
sound (8x oversampling, not simulating a turntable):
Push the "SETTING" button
1 times, the 1st and 2rd digit will blink, then push the right "Selector"
button to set the value to "O8".
Then push the "SETTING" button
one more time, the 3rd digit will blink, then push the right "Selector" button to set
the value to "n".
2. Settings for NOS1 and phono simulation mode:
Push the "SETTING" button 1 times, the
1st and 2nd digit will blink, then push the right "Selector" button to set
the value to "N1" .
Then push the "SETTING" button once again,
the 3rd digit will blink, then push the right "Selector" button to
set the value to "S" .
3. Settings for NOS0 mode with phono simulation
(new option combination to get the warmest and smoothest sound ):
Push the "SETTING" button 1
times, the
1st and 2nd digit will blink, then push the right "Selector" button to set
the value to "N0" .
Then push the "SETTING" button
one more time, the
