CAUTION
Installation
Make sure that the speaker is positioned in a stable and secure way in order to avoid any dangerous
conditions for persons or objects.
CAUTION
Connection
For connecting the speaker, use only qualified and experienced personnel having sufficient technical
knowledge or specific instructions for making the connections correctly and thus preventing electrical
dangers.
The entire sound system must be designed and installed in compliance with the current standards and
regulations regarding electrical systems.
The loudspeakers must be wired properly in phase (be sure to observe the correct + / - polarities
between amplifier and speaker) to give the correct sound reproduction, especially when the speakers
are placed close to each other or in the same room.
The loudspeaker's connecting cable must have wires of adequate gauge (possibly intertwined to
minimize the inductive effects caused by the coupling with electromagnetic fields) and proper
insulation.
CAUTION
Hearing loss
Excessively high sound levels may cause permanent hearing loss. The sound pressure levels that
cause hearing loss vary significantly from one person to another and according to the duration of the
exposure. To avoid potentially dangerous exposure to high sound pressure levels, adequate
protection must be used by whoever is exposed to such pressure levels.

DESCRIPTION
"ARENA" is a series of wooden two-way passive loudspeakers designed for medium to
large sized rooms.
They are all made from birch wood and the various fixing clamps, the pole mount socket
and the handles ensure easy installation and transport.
The loudspeakers can be placed on wall shelves or suspended through the fixing clamps
placed above, under or on the side of the loudspeakers.
The lower part of the box has a standard pedestal support (D36mm).
The loudspeakers of the ARENA series feature passive crossover filters with a slope of
12dB/oct for the low-pass part, 18dB/oct for the high-pass and a self-resetting thermal
protection circuit on the driver to prevent protracted overloading.
CONNECTIONS
WARNING
To avoid electric shocks, ensure that your amplifier is switched off when you plug in
the loudspeaker. Before turning on the loudspeaker, be sure that the connections are
correct to avoid short circuits or wrong connections.
The connection panel at the back of the loudspeaker features two 4 pole Speakon
connectors: the first socket is the sound signal input socket and the second socket may
function as an output terminal for the connection with another loudspeaker.
The connections are:
1+
for the positive signal
1-
for the negative signal (ground)
2 +
not connected
2 -
not connected
If you wish to send the amplified signal from one loudspeaker to the other, be sure that the
nominal impedance resulting from the connection is never lower than the minimum
impedance of the power amplifier. This is done to prevent overheating or, worse, damages
to the amplifier.
The loudspeakers of the ARENA series have a nominal input impedance of 8 ohms and this
must taken into account when making the connections.

ROTATING HORN

When used horizontally, the loudspeakers of the ARENA series allow to maintain the same
coverage angle through a rotating horn.
Speakers are always supplied by the manufacturer with the horn driver positioned
horizontal at 90°.
If you wish to change the coverage angle (FIG. 5):
-
undo the fixing screws of the grille
-
remove the front protective grille by slightly pressing on one side and taking the
grille
off the special slots
-
undo the eight fixing screws of the horn
-
rotate the horn in the desired position (the horn should never be removed from the
loudspeaker)
-
tighten the fixing screws of the horn
-
put the grille back in the special side slots and tighten the screws of the grille.
