WARNING! speaker connections should be only made by qualified and experienced personnel having the technical
know-how or sufficient specific instructions to ensure that connections are made correctly and prevent any electrical danger.
To prevent any risk of electric shock, do not connect speakers when the amplifier is switched on. Before turning the system
on, check all connections and make sure there are no accidental short circuits.
The entire sound system shall be designed and installed in compliance with the current local laws and regulations regarding
electrical systems.
Make sure all speakers are connected in phase to ensure a correct sound reproduction.
All models have an internal transformer for connection to 70-100 V constant voltage lines� Alternatively, they can also be connected as low
impedance (8 Ω) speakers�
3.1 SETTING THE POWER WHEN CONNECTED TO 100 / 70 V CONSTANT VOLTAGE LINES
(WMR 50T and WMR 60T only)
If speakers are connected to a constant voltage line, set the selector to one of the positions from 1 to 5 (70 V) or from 1 to 4 (100 V) to choose
the power rate (according to the line voltage)�

WARNING!
- DO NOT select the position 6 (8 Ω) (as this may damage the speaker and the amplifier)!
- DO NOT select the position 5 when linked to a 100 V line!
- The speaker input voltage (Vd) shall correspond to the amplifier output voltage (Va).
- The sum of nominal power values (Pd x n) of all speakers connected to the line shall not exceed the amplifier power (Pa).
