“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 operate the speaker system at excessive levels
for a long period of time.
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, pull it out by the plug. Do not pull the
cord itself. Never touch the plugs with wet hands.

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, do not operate components with
open input/output terminals.
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 3 x DRIVER GAIN switches allow tonality adjustments of the
3 x horns in –1.5 dB, 0 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.

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 “0 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
+/– 10.5 dB = all 3 switches in “+” or “–“ position

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 tailorize 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. The crossover f requency in its factory setting is linear.
The frequency response of the subwoofer seamlessly crosses over to
the frequency response of the midrange horn. Both response
curves do not overlap and there is no gap inbetween. The crossover
point 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 f ilters 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 available room modes. Or play 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 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 needs to 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 tip 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 tip 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.
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. 3,0m.
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 till 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 single-stranded 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 button to reset. If the E–FUSE
stops again, 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 . In order to
avoid any kind of sound degradation, the usual glass–fuse is
replaced as standard in all Avantgarde E–FUSE controlled devices
by a massive copper bolt to bridge the power.
For whatever reason this copper bolt may at any time be replaced
by a conventional 2.5 amp slow blow glass fuse.
FUTURE UPGRADES
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 files for the
firmware of the built–in controller chipset.
�Future options only; not available upon release.
