eMSP50Ti operates into high or low impedance. For this reason, it incorporates a
terminal block located on the rear panel.

Note:
If the loudspeaker is used in 70V installations, the corresponding powers for
the 100V position will be reduced to half those indicated on the switch. To one
quarter for 50V installations.
The low-impedance connection will allow the loudspeakers to be configured for
operating under these conditions with a maximum power of 250 W. If this setup is
adopted, consideration must be given to amplifier limits when several
loudspeakers are connected to its output, especially if the overall impedance is
below 4
. Furthermore, it is important that the cable connecting the amplifier
outputs to the loudspeakers is of good quality and as short as possible; this is of
special significance when long distances have to be covered and loudspeaker
impedance is low.
