ZeroUno PLUS ULTRA Preamplifier
The ZeroUno PLUS ULTRA has been developed based on the experience acquired and lessons learned
from our top-of-the-line 90Wrms in pure class A La Scala power amplifier. La Scala exudes authority and
maintains absolute control of your loudspeakers, with an astonishing reproduction voted to a natural
reproduction in any style of music.
The 90Wrms are reached using only 6 components and without any capacitor in the signal path: mono
triode, and mono MOSFET, with full transformers coupling at the input, interstage, output and, last but not
least without capacitor on the signal.
ZeroUno ULTRA is the perfect partner of a reference power amplifier to reach the musical authority and
effortless ease.
Into the ULTRA there is the shortest possible signal path, with only 10 components used and without any
capacitor that can leave its fingerprint. Essentially one ECC82 and one JFET connected in parallel to form a
complementary couple, one amorphous core transformer, and 4 resistors. All the superfluous circuities have
been cancelled, for a reproduction as natural as possible.
Of course the power supplies are the core of the unit, with 90% of the electronic implemented occupied by
them.
Instead of the ECC82 the ECC88 can be used, plug and play.
To finalize the electronic design a reference chain was settled up: turntable Thuono TH400, tonearm Thiele
TA01, very low output cartridge DV KARAT 17DX with gold coils, Aesthetic RHEA phonostage, LaScala
power amplifier, high definition and high efficiency loudspeakers Sigma Acoustic MAAT Vector.
Exhaustive investigation and auditioning have been done for the perfect selection and match of every
component inside the ULTRA, and some proprietary parts have been custom-designed.
The system was presented with success at the last HiEnd in Munich.
The basses are firm, well-defined, with massive attack. Together the gentle richness of detail at the medium
high frequencies contribute to the preamplifier’s ability to render the reproduction as natural as possible, with
three-dimensional realism and instrumental placement … what we call “natural listening”, or “slow sound” to
remember the "slow food" approach.
Both the ZeroUno SE, digital inputs only, and ZeroUno PLUS preamplifier, can be upgraded to the ULTRA
version.

Skip to the following active INPUT
How to pair the remote controller (RC).
The RC coming with each ZeroUno PLUS 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 PLUS do the following:
1) Move the RC in front of the ZeroUno PLUS (about 1 meter).
2) Press any button on the RC.
3) Enter in SETUP mode pressing the SETUP button for at least 2
seconds and less than 10 seconds.
4) When in SETUP Mode, KEEP PRESSED the INPUT button close
the Volume knob.
5) Holding the INPUT button pressed, PRESS again the SETUP button.
6) Release both buttons (INPUT & SETUP).
7) 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 PLUS, 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!!!).
To get an instant feedback about the ZeroUno PLUS status, every time the VOLUME, BALANCE and MUTE
button is pressed at the RC, the display shows the value for VOLUME, BALANCE and MUTE in tall digits for
5 seconds.

When the VOLUME buttons are pressed the attenuation changes in
steps of 1.0dB.
The range is -65dB to 0dB.
If the button is pressed constantly, the attenuation changes quickly.

When the BALANCE buttons are pressed, the balance changes in
steps of 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 MUTE button is pressed, the
ZeroUno
PLUS is muted and the
display never switches back to the standard size view until the MUTE
button is pressed again.
After the MUTE button is pressed again, the ZeroUno PLUS is un-muted.
The display turns back into normal operation.

When the MENU button 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 PLUS 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 key is pressed within 10 seconds, the ZeroUno PLUS 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.
RESTORE OF FACTORY SETTINGS
To RESTORE the factory setup, the SETUP button at the front panel of
the ZeroUno PLUS must be pressed for at least 10 seconds.
The RESTORE command takes action after the SETUP button is
released.
All parameters of all INPUTs will be RESET to the factory values.
A countdown running in the second row of the display is shown,
when the ZeroUno PLUS has engaged the RESTORE command.
Once engaged, it is no possible to stop the RESTORE command.
The Specifications in this document are subject to change without notice.
