VOLUME
In PLAY mode turning the right knob clockwise or counter clockwise
changes the VOLUME (up/down) in steps of 1 dB.
While rotating the volume knob, the volume level is shown at the
display.
Volume range is -60dB –0dB.

Volume.:.-20dB..MUTE
Balance:.R0.5.PHASE+
INPUT..:.USB
In PLAY mode the display reports the status of the ZeroUno DAC.
•The first row at the display shows the LOCK on the coming signal.
•The second row shows the VOLUME (really the attenuation) in dB.
•The third row shows the BALANCE and the ABSOLUTE PHASE.
•The fourth row shows the active INPUT.
When a MUTE appears at the display, there is no signal locked at the
selected INPUT and the ZeroUno DAC has automatically switched to
MUTE.
SETUP
Press the SETUP for at least 2 seconds and LESS than 10 seconds
to enter in SETUP Mode.
The value of each parameter is visible at the display.
Press the SETUP button again to skip to the next parameter.
Rotating the right knob (VOLUME) changes the parameter values.
If no button is pressed, or the right knob is not turned within 10
seconds, the ZeroUno DAC automatically stores the values shown at
the display and switches back to the PLAY/MUTE mode.
All selected parameters are stored in a non volatile memory, tokeep
the setup information after the unit is switched off.

How to pair the remote controller (RC):
The RC coming with each ZeroUno DAC has been paired to the unit
already in the factory by selecting one of 256 possible pairing codes.
In case of interference with the RC´s of other electronics in the
household, the preselected RC code can be changed at any time.
To pair the RC and the ZeroUno DAC do the following:
•Move the RC in front of the ZeroUno DAC (about 1 meter).
•Press any button on the RC.
•Enter in SETUP mode pressing the SETUP button for at least 2
seconds and less than 10 seconds.
•When in SETUP Mode, KEEP PRESSED the INPUT button close the
Volume knob.
•Holding the INPUT button pressed, PRESS again the SETUP button.
•Release both buttons (INPUT & SETUP).
RC now is paired.
If there is still interference with other RC´s in the household, please restart the process above described to
generate another code.
When the RC communicates with the ZeroUno DAC, a dot appears at the bottom-right corner of the display.
If this dot does not appear, check the battery inside the RC controller (battery type: CR2032B)
When replacing the battery, pay attention to insert it in the right way (check +/- position!!!).
INPUT BUTTON
Press the INPUT button to switch from one input to another in the
following order:
 RCA SPDIF
 XLR AES/EBU SPDIF
 OPTICAL SPDIF
 USB (i2S or DoP with auto detection)
The de-emphasis filter will be automatically activated if the signal at
the input was recorded with emphasis.

To get an instant feedback about the ZeroUno DAC status, every time a button is pressed at the RC, the display
shows for 5 seconds the value in big digits.

When the VOLUME are pressed, the attenuation changes in steps of
1.0dB.
The range is -60dB to 0dB.
If the key is pressed constantly, the attenuation changes quickly.

When the BALANCE buttons are pressed, the balance changes in
steps of 0.5dB.
The range is LEFT -5.0dB to RIGHT +5.0dB.
To help the user the first row of the display reports a bar showing the
position of the balance value in the range -5.0dB to 5.0dB.
When the balance is set to 0.0dB the display shows clearly the
condition.

When the MUTE button is pressed, the ZeroUno DAC is muted and the
display never switches back to the standard size view untill the MUTE
key is pressed again.
After the MUTE key is pressed again, the ZeroUno DAC is un-muted.
The display turns back into normal operation.

When the MENU key is pressed, the value switches between absolute
polarity listening (PHASE+) and inverse absolute polarity listening
(PHASE-).
As during the recording, the mastering and the production process the
absolute polarity of the music program is changing many times, the
final digital master file can be stored in inverted polarity. As some
listeners are very sensitive to this fact, the ZeroUno DAC gives the
customer the option to change the absolute polarity of the music file by
pushing the MENU button at the remote control.
If no button is pressed within 10 seconds, theZeroUno DAC automatically
stores the values shown at the display and switches back to the
PLAY/MUTE mode.

When there is a change in the sampling rate of the incoming music file,
the locked frequency is shown in big digits.
By the parameter BIG SAMPLING RATE is possible to toggle on / off
the function.
