SAFETY INFORMATION
PRECAUTIONS ON INSTALLATION
Do not carry the speakers by the horn.
Place the loudspeaker on a flat floor with a load-bearing capacity
that adequately supports the weight of the loudspeakers.
To prevent internal heat build–up in the components, place units in
a location with sufficient air circulation. Do not install the speakers
in a location near heat sources such as radiators, or in a place
subject to direct sunlight, excessive dust, or mechanical vibration.
Connect everything securely. Always insert the cables and plugs
fully into the jacks. A loose connection may cause hum pick-up and
can damage the system. Use only high–quality cables with self–
tightening banana speaker and RCA or XLR plugs.
To avoid damaging the finish, never use alcohol, paint thinner or
aggressive cleaners to clean the components.
Read this operators manual thoroughly before operating the
speaker system.
OPERATING VOLTAGE
The amplifier can be powered from main voltages of 90 – 250 volts
with a mains frequency of 50-60 Hz.
SAFETY INFORMATION
CAUTION
To prevent fire, shock or damage, do not expose the components to
rain or moisture.
Conditions for operation:
room temperature 5 – 35° C,
humidity 10 – 75%
It is intended to alert the user of the presence of uninsulated
“dangerous voltage“ within the products enclosure. To avoid
electrical shock, do not open the cabinet of the components.
Excessive sound pressure levels might cause serious damage to
your health. Do not turn up the volume of the loudspeaker system
to loud!
Should any solid object or liquid fall into the cabinet of the
components, unplug the unit and have it checked by qualified
personnel before operating it any further.
Unplug the components of your system from the wall outlet and
antenna if they are not to be used for an extended period of time. To
disconnect the power cord, always pull on the plug and never on the
cord directly. Never touch the plugs with wet hands.
Only have the system installed and repaired by authorized
personnel.
These loudspeakers are designed for the playback of audio signals.
Any misuse, especially commercial operation, will invalidate the
warranty.

UNPACKING
UNO SD & DUO SD
When unpacking and setting up the speaker, be aware of their
heavy weight! For this work we strongly recommend the assistance
of at least three or more persons!
Do not move or carry the speakers by holding the horn assembly.
The horns may get damaged.
Place the packaging carton upright, remove the clips and open the
carton.
Carefully pull the loudspeaker forward using recessed grips.
Carefully lay the loudspeaker on its back.
Remove the lower EPP packaging protection.
Carefully lift the speaker to the upright position and remove the
EPP packaging protection.

SAFETY PRECAUTIONS
ON INSTALLATION
The power to all components must be switched “off” (or
disconnected from the household AC) before making any audio
connections.
To prevent malfunction/defects, never operate components with
unassigned input sockets (unwired)!.
Control the polarity of speaker cables! Never mix up “+” and “–“.
Wrong polarity will deteriorate the sound quality and can damage
amplifier and the active power module of the subwoofer.
Do not short circuit the +/– electric poles of the speaker cables.
Use high quality cable with solid speaker plugs (spades, bananas
etc).

AUDIO SOUND ADJUSTMENTS
The 2 x DRIVER GAIN switches allow the volume of the 2 x horns
to be adjusted in –1.5 dB, O dB (= linear) and +1.5 dB steps.
MID controls the level of the midrange horn (approx. 200–4,000 Hz)
HIGH controls the level of the high frequency horn (above 4,000 Hz)
The factory setting is the "O dB" position for all 2 switches.
Adjustments can be made according to personal taste, to match the
tonal "tonality" of the connected source equipment, or to slightly
correct for room acoustic influences.
In practice, the tonal balance between the 2 x f requency bands can
be changed by up to 3 dB. Example:
If the HIGH switch is set to +1.5 dB and the MID switch is set to –1.5
dB, the relative loudness of the midrange speaker compared to the
tweeter horn is reduced by 3 dB. This could be used as a beneficial
voicing for "shrill" recordings (with overemphasized midrange) or in
an acoustic environment with a "peak" in the midrange.

GAIN ADJUSTMENTS
The 3 x TOTAL GAIN switches allow the adjustment of the gain of
the speakers to the strength of the line level signal f rom the
connected preamp. To avoid sound degrading potentiometers in
the signal path, 3 x switches in an additive stepped arrangement are
being used. Factory default is the “O dB” position for all 3 switches.
Practical example: If a preamp already makes big “jumps” in sound
level by turning the volume knob just slightly, reducing the iTRON’s
input gain by up to –10.5 dB may increase the adjustment angle of
the pre amps volume knob considerably, thus enhancing its
practical usefulness for fine volume adjustments.
The following steps are possible:
+/– 1.5 dB = left switch in “+” or “–“ position
+/– 3 dB = central switch in “+” or “–“ position
+/– 4.5 dB = central & left in “+” or “–“ position
+/– 6 dB = right switch in “+” or “–“ position
+/– 7.5 dB = right & left in “+” or “–“ position
+/– 9 dB = right & central in “+” or “–“ position

OPERATION – SUBWOOFER DSP AMP
DSP VOLUME SETTINGS
The bass response of the speaker will be influenced by the room and
the position of the speaker. This might cause the bass response of
the speaker to be strengthened or weakened. Thus as the f irst step,
the overall bass volume needs to be aligned to compensate these
effects.
Press the VOL –button to increase or the VOL –button to
reduce the volume of the bass response. The set volume is indicated

DSP USER INTERFACE
The above picture shows the graphical user interface that is
available for each of the subwoofers individually after installing and
starting the software.
Please note that all changes in the Avantgarde control software
immediately become audible in the speaker. This way it is easy
to verify the changes by listening and fine adjust if required.
OPERATION – SUBWOOFER DSP AMP
DSP SETTINGS
The BASS GAIN slider sets the overall volume of the subwoofer.
The BASS BOOST slider increases the low frequency response
below 45 Hz. This allows to tailor the bass response from “linear” to
“fat”.
For individual frequency settings use the 8 x band equalizer .
Each of the 8 x bands can be increased or decreased by up to 4dB.
This can be used to tailor your bass response to specific sounds
(linear, techno, disco, pop, etc.) or to reduce some wide–band room
resonances.
The LPF–RANGE slider sets the upper crossover frequency of the
subwoofer. In the factory setting the crossover f requency is
optimized for a linear transition, the frequency response of the
subwoofer blends seamlessly into the frequency response of the
midrange horn. The crossover frequency can be used to adjust the
“tonal balance” of the system.
When set to a higher f requency, the subwoofer will partly overlap
with the midrange horn response. This will add “warmth” and give
a richer “body” to the sound character of certain voices and
instruments.
If the crossover f requency is purposely set to a lower f requency,
subwoofer and midrange frequency response will have a small gap.
The tonal balance of the system will shift to a more horn typical
“dynamic” and “punchy” sound.
FILTER 1 & 2 are narrow band “notch” filters with a negative
gain of –3dB or –6dB. These filters can be used to elimante/reduce
unwanted narrow band resonance f requencies of the room.
Use commonly available frequency sweep apps to detect the
position (Hz) of possibly occuring room resonances. Or play bass
heavy music through your system and slowly slide the FILTER set at
–6dB upwards until the “boominess” improves.

FINE TUNING
TOE–IN & TOE OUT
By facing the speakers inwards (toeing–in) or outwards (toeing–out)
you can further affect the focus and tonal balance of the system.
By toeing–out, the sound appears to be less “direct” or “forward
sounding”, but this may affect the focus of the centre image.
Toeing–in emphasizes increased focus on the centre image, but
may affect the width of the stereo image.

ROOM PLACEMENT
We recommend to place both speakers with the horns facing
towards the listener. This setup projects the high-frequency and
imaging precision with maximum stability into the center of the
room or in the direction of the ideal listening position.
Due to the controlled dispersion characteristics of the horns the
speaker will excite significantly less unwanted reflections from the
room walls compared to conventional speakers. Thus they can be
positioned closely to back walls or corners (both or only one speaker
in the corner!).
Choose a position for the speakers in your listening room. Both
speakers and your listening seat should form an approx. equilateral
triangle. Ideally each side of the triangle should be approx. 3,0 –
4,0m.
The speakers should be toed–in with the horns pointing directly to
the listening position.

LISTENING HEIGHT
Depending on the listening distance and seat height, it may be im‐
portant to tilt the speaker systems forward or backward.
If necessary, tilt the speaker slightly forward or backward by turning
the handle of the 4 x spike assemblies until the system is opti‐
mally aligned.
RUN–IN TIME
Brand new horns and subwoofers usually need at least 40 hours of
running–in. During this period sound quality will improve
continuously. Please leave the subwoofers ON during this run–in
period.
After this run–in, the sound might have been altered and it might
be necessary to slightly re–tune the system set–up (positioning and
subwoofer-settings).
WARM–UP TIME FOR ITRON
The ITRON electronics uses pure CLASS–A circuits with Zero–
Feedback. To reach its full sonic potential the components need to
be fully warmed–up. A sufficient warm up time (> 15 minutes) prior
to serious listening is recommended.

12V DC TRIGGER
The 12V DC TRIGGER sockets of the ITRON & SPACEHORN electron‐
ics features an “IN”–socket and an “OUT”–socket . This way it
is easily possible to remotely switch ON/OFF additional devices (ad‐
ditional SPACEHORNS etc.) by simply daisy–chain the 12V trigger
signal.
Wiring can be made with mono or stereo jack cables.
E–FUSE
All Avantgarde electronics are equipped with a state–of–the–art
electronic protection circuit. This E–FUSE continuously monitors
the unit and in the event of a fault immediately interrupts the flow
of current with unrivaled precision & speed and thus protects the
device from damage.
When the E–FUSE has tripped, the current flow will be interrupted
and the device stops operating. The red engaged fuse LED will
illuminate. Press the E–FUSE RESET button to reset. If the E–
FUSE keeps tripping, a permanent malfunction has occurred.
Disconnect the device from the mains and get it serviced by your
dealer.
All Avantgarde electronics are equipped with a mains ON–OFF
power switch that includes an external fuse holder . To avoid any
kind of sound degradation caused by conventional fuses, the
accessoried include glod-plated copper bolts that can replace the
glass fuses used in the factory and thus eliminating any sound
degradation at this point. NOTE: The certified final tests during final
assembly are performed with glass fuses in place, therefore these
are also installed as standard in the delivery status.
For whatever reason this copper bolt may at any time be replaced
by a conventional 2.5 amp slow blow glass fuse.
FUTURE UPGRADES (optional future upgrade only).
Your system has already been equipped with a wifi antenna port to
support future upgrades. This includes remote control signals (from
apps etc.) and receiving OTA (over the air) update f iles for the
firmware of the built–in controller chipset.
