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 suff icient 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 f rom 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 f rom 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 wif i antenna port to
support future upgrades. This includes remote control signals (f rom
apps etc.) and receiving OTA (over the air) update f iles for the
f irmware of the built–in controller chipset.

Future options only; not available upon release.
