Use 1 output only (among the 3 available: 100 V, 70 V, 4
Ω
).
100 / 70 V CONSTANT VOLTAGE OUTPUTS
-
Each loudspeaker shall have a line transformer with the input voltage equal to the line
voltage (100 / 70 V).
-
The loudspeaker total power shall not be higher than the amplifier maximum power.
LOW IMPEDANCE OUTPUT (4
Ω
)
-
The loudspeaker total impedance shall not be lower than 4
Ω
.

-
Loudspeaker models shall be chosen by considering the max. power that the amplifier
can deliver.
-
Loudspeaker line should be as short as possible; long cables may need large wire
cross-sections.
-
Do not use, at the same time, both the low impedance output (4
Ω
) and the constant
voltage output (100V or 70V), as this overloads the amplifier.
