INPUT BUTTON
Press the INPUT button to switch from one input to another in the
following order:
 RCA SPDIF
 BNC SPDIF
 OPTIC SPDIF
 USB (i2S or DoP with auto detection)
The de-emphasis filter is automatically activated if the signal at the
input was recorded with emphasis.
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.
DISPLAY
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.
Range is from -60dB to 0dB.
The third row shows the balance and the listening phase.
The fourth row shows the active INPUT.
SETUP
Press the SETUP for at least 2 seconds and LESS than 10
seconds to enter in SETUP Mode.
For each parameter its value is visible at the display.
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 no volatile memory, so that
the setup information is not lost after powering off the unit.

INFRARED REMOTE CONTROLLER
Key Value
Balance left to right in steps of 0.5dB each. Range is 0-5dB
Volume Up and Down steps of 1.0dB. Range is -60dB to 0dB
Phase Absolute Polarity < toggle > Inverse Absolute Polarity
Mute Mute < toggle > Play
Setup See SETUP KEY on the front panel description
The remote controller (RC) coming with each ZeroUno DAC has been
paired already with the DAC 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 change the code, first move the RC close to the ZeroUno DAC (about
1 meter). Then press the SETUP and POLARITY buttons at the RC
simultaneously for at least 5 seconds.
In a second step the RC must be paired with the DAC again.
To pair the RC, press the SETUP button at the front of the ZeroUno DAC for at least 2 seconds to enter in
SETUP mode, release the button and finally press simultaneously the SETUP and the INPUT buttons.
If there is still interference with other RC´s in the household, please restart the above described process to
generate another code.
The procedure is the same if you have a compatible RC.
To have an immediate feedback of the ZeroUno DAC status, every time a key is pressed at the RC, the display
shows in big digits and for 5 seconds the value set.

When the VOLUME keys are pressed, the attenuation changes with
steps of 1.0dB. Range is -60dB to 0dB.
If the key is kept pressed the attenuation changes quickly.
If no key is pressed within 10 seconds the ZeroUno DAC automatically
stores the values shown at the display and switches back to the
PLAY/MUTE mode.

When the BALANCE keys are pressed, the balance changes in 0.5dB
steps. Range is LEFT -5.0dB to RIGHT +5.0dB.
To help the user the 1st 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.
If no key is pressed within 10 seconds the ZeroUno DAC automatically
stores the values shown at the display and switches back to the
PLAY/MUTE mode.

When the MUTE key is pressed, the ZeroUno DAC is muted and the
display never goes back to the standard size view till the MUTE key is
pressed again.
When the MUTE key is pressed again ZeroUno DAC is un-muted the
display turns back into normal operation and the parameter is stored.
When a MUTE appears at the display in standard size means there is
no signal locked at the selected INPUT and the ZeroUno DAC
automatically forces to the MUTE condition. This function is totally
independent from the MUTE imposed by the user.

When the LISTENING POLARITY key is pressed the value is toggled
between absolute polarity listening, showed PHASE+, and inverse
absolute polarity listening, showed 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 round toggle switch at the remote control.
If no key is pressed within 10 seconds the ZeroUno DAC automatically
stores the values shown at the display and switches back to the
PLAY/MUTE mode.

SETUP:Jitter.Filter
>bbbbbfilter.ON
When the MENU key is pressed, the ZeroUno DAC enters in the
SETUP procedure starting from the Jitter Filter parameter.
The feature of the keys changes totally from before. See aside.
The big digit indication is not activated and the sequence of parameters
possible to set by the RC is:
Jitter Filter > FIR filter > IIR filter > DAC resolution > Sampling Rate >
Balance > Phase > Brightness > Dimmer > Oversampling
If no key is pressed within 10 seconds the ZeroUno DAC automatically
stores the values shown at the display and switches back to the
PLAY/MUTE mode.
The countdown on the first row helps to control the left time.
At any time is possible to store immediately the parameter set by pressing
the EXIT & STORE key.
In this case the countdown for the automatic store & exit is bypassed.

To give the user maximum flexibility, the SETUP mode is implemented.
To RESTORE the factory values the SETUP button at the front panel of the ZeroUno DAC must be pressed for
at least 10 seconds.
A countdown running on the 2 row of the display assists the user during this process.
