SAFETY INFORMATION
PRECAUTIONS ON INSTALLATION
Do not carry the speakers by the horns.
Place the loudspeakers 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
too 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
TRIO G3
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 & the phase alignment slider of the tweeter may get
damaged.
Unscrew and remove top cover of the wooden crate. Note, that the
screws may be hidden under the red “caution”–tape.
Unscrew and remove the side panels of the wooden crate.
Pull the speaker by its base from its padded bearing surface until its
balance point is noticeably outside the bearing surface. Now the
base f rame can be lowered onto a wheeled board and the
loudspeaker can be carefully brought into the vertical position.
Use a wheel board (min. size 70 x 70cm) to transport the speaker to
its listening position. Note, that the spherical horns can be removed
by unscrewing them counterclockwise. This makes it easier to pass
through narrow doorways.
UNPACKING

ADJUSTABLE FEET
SPACEHORN
The SpaceHorn is shipped with the 4 x adjustable gliding feet
mounted on the bottom plate of the speaker body for a horizontal
placement of the SpaceHorn (see graph 1 to 3, next page).
If the SpaceHorns are placed vertically (see graph 4 to 7, next page)
the gliding feet need to be relocated. Carefully tilt the SpaceHorn to
the narrow backside of the speaker, so that both the 4 x gliding feet
and the 4 x metal covers become accessible. Use a soft underlay (eg.
blanket) not to scratch the speaker body.
Use the triangle tool to remove the metal covers of the SpaceHorns.
Now swap the positions of the 4 x gliding feet and the 4 x metal
covers.
Place the SpaceHorns to the final listening position.
Use the height adjustment tool (stell rod) to adjust the gliding feet
of the SpaceHorns.
ADJUSTABLE FEET
TRIO G3
The Trio G3 stands on 3 spike absorber elements with integrated
synthetic–felt pads to protect the underside of the base f rame
during speaker placement and alignment.
The spikes are in the accessories box and can be screwed in
from below at the position shown here. To do this, tilt the speaker
over one side of the base f rame at a time and completely screw in
the spike into the now raised absorber element.
Then unscrew the spikes by hand until they lift the speaker and thus
decouple it from the floor. Depending on the floor covering, place
the floor protection disks underneath beforehand if necessary.
By unscrewing the individual spikes to varying degrees, the
speakers can also be precisely aligned vertically to the listening
position.

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
amplif iers 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).

be used to switch into standby mode, but upon next
power cycle the speaker will turn ON again directly.
MODE B speaker is ON when a 12VDC remote switch-on
voltage is detected at the remote-trigger socket
The speaker switches OFF automatically when the 12V
trigger voltage is switched OFF.
MODE C the frontal sensor switch is used to toggle between
speaker ON & STANDBY.
MODE D speaker is switched ON & STANDBY by remote control
signal (optional future upgrade only).
CONNECTION – TRIO G3 ITRON VERSION
BALANCED XLR CONNECTION
Line level connections feature balanced XLR connectors/terminals.
The pin assignment of these follows the EIA RS-297-A standard:
PIN 1 = GND, PIN 2 = HOT, PIN 3 = COLD. Never use cables with
differing pin assignment! This will deteriorate the sound quality and
can damage the amplifiers and/or the active power modules of the
subwoofers.
Connect the volume-controlled line-level output of your
preamplifier to the balanced line-level input of the TRIO G3
speaker with an XLR cable.
Connect the balanced XLR output of the TRIO G3 speaker and the
balanced XLR input of the SPACEHORNS with the long XLR jumper
cable. The jumper cable is included in the accessory box.
If you use more than 1 x subwoofer per channel, connect the
balanced XLR output of the SPACEHORNS No.1 and the balanced
XLR line level input of the SPACEHORNS No.2 with the shorter XLR

OPERATION – TRIO G3 ITRON VERSION
AUDIO SOUND ADJUSTMENTS
The 3 x DRIVER GAIN switches allow the setting of individual
volume correction of the 3 horns in –1.5 dB, O dB (= FLAT) and +1.5
dB steps.
LOW adjusts the level of the lowrange horn (100–600 Hz)
MID adjusts the level of the midrange horn (600–4.000 Hz)
HIGH adjusts the level of the tweeter horn (above 4.000 Hz)
Factory default is the “O dB” position for all 3 switches.
Adjustments may be made according to personal taste, for
adapting to the tonal “brightness” (or lack thereof) of connected
source equipment, or to mildly correct room acoustic influence.
In practice, the tonal balance between the 3 x f requency bands can
be altered up by up to 3 dB. For example:
With the HIGH and LOW switches set to +1.5 dB, and the MID switch
set to –1.5 dB, the relative volume of the midrange is reduced by 3
dB against the tweeter and lowrange horns. This could be used as a
favorable voicing for “shouty” recordings (with over-emphasized
midrange frequency content) or in an acoustical environment that
has a “peak” in the midrange.

OPERATION – TRIO G3 ITRON VERSION
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

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.

BASS GAIN
OPERATION - SPACEHORN
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 frequency 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.

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.
As the tweeter is located outside of the centre axis of the speaker,
toeing–in will increase its distance to the listener in relation to the
acoustical centre of the low & midrange horn. Toeing–out will
decrease its distance.
In order to compensate for this acoustical runtime differences the
tweeter can be moved forward when toeing–in and moved
backwards when toeing–out. The correct offset of the tweeter is
always 48,5 cm.
Choose your favorite toe–in or toe–out
position.
Take a cord and measure the distance
(xxx,x cm) from your listening position to
the centre top rim of the big lowrange
horn.
Take this length (xxx,x cm) and add
48,5 cm. This is the correct distance f rom
your listening position to the centre top
rim of the tweeter horn.
Loosen the knurled knob to release
the tweeter and move the tweeter
forward or backward respectively.

ROOM PLACEMENT
We recommend to place both speakers with the tweeter facing to
the inside. This setup reflects the high-frequency and imaging
precision with maximum stability into the center of the room or in
the direction of theideal listening position.
Due to the controlled dispersion characteristics of the horns the
speaker will excite 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 (tweeter facing to the inside) 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 midrange horns pointing
directly to the listening position.

LISTENING HEIGHT
Depending on the listening distance and the height of your seat it
might be important to raise or lower the speaker systems. Ideally
your ears are in level with the height of the centre of the tweeter
(approx. 110 cm above ground).
If not, slightly incline the speaker forward or backward by turning
the knurled screw of the spike assembly until the tweeter
is pointing at you.
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
accessories include gold-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.
