Note:
The loudspeaker distribution along a 70/100V line historically arises from
the technical requirement to mix loudspeakers of different impedances and/or
powers on the same amplification line or channel, but without any need to worry
about the total impedance of the full assembly. Moreover, this solution enables
long cable runs with significantly smaller sections that those usually employed in
low-impedance installations, but with minimum power losses.
WARNING!
If the system is accidentally connected with the switch in the 100 V/60
W position to a low-impedance amplifier, no damage will be caused to the
loudspeaker, but its performance will be well below its specifications. If the
loudspeaker is accidentally connected to a 70/100 V line, in the 8 Ω, it will be
seriously damaged.

LOCATION AND INSTALLATION
In general, the following rules will be followed:
The unit must always be installed on firm, solid surfaces.
Ensure that the surface on which the loudspeaker is to be installed can
withstand its weight.
Always use a safety cable to secure the loudspeaker installation.
For good sound reproduction, there must not be any obstacles between the
loudspeaker and the audience.
High frequencies, unlike bass frequencies, are extremely directional and any
obstacle will involve attenuation in their response.
