Installation
The loudspeaker can be installed both on the ceiling and
on a vertical surface. It is strongly recommended that the
mounting surface is flat (not curved).
Ensure that the mounting surface is free from
obstructions, pipes or studs, either in front
and behind the surface.
The cable runs and cable pipes shall be
set according to the loudspeaker system
configuration. The cables must be of
adequate quality, suitable for the installation’s
environmental conditions and with proper
copper section to minimize power loss.
Common input wire (-) is BLACK.
Signal wire (+): connect only one wire among
the input taps wires.
Select the input tap wire according to:
• the voltage level of the line;
• the wattage required to produce the desired
sound pressure level for your application,
allowing for some additional headroom.
The sum of the power taps of the loudspeakers
connected to the same line shall be 20% lower
than the amplifier’s wattage rating.

Pull the speaker wire out of the hole and connect
it to the loudspeaker.
Insert the loudspeaker into the hole and tighten all
the clamp screws with a Phillips #1 screwdriver.
Reposition the grill on the loudspeaker.

Loudspeaker Wiring
Ensure that the amplifier is unplugged from the mains
before making any connections.
Connect the input terminals of the loudspeakers to the
speaker output terminals of the amplifier. Always check
to ensure polarity is correct: L(left) to L, R(right) to R,
“+” to “+”, and “-” to “-”.
Note: In case of sonic artifacts, roughness or distortion,
reduce the signal volume to a lower setting. Never allow
the amplifier to be driven into “clipping”. Damage caused
by operating the speakers at distorted volume levels is
not covered by the warranty.
