LOW IMPEDANCE OUTPUT (4
Ω
)
-
The loudspeaker total impedance shall not be lower than 4
Ω
. Note: a total impedance
equal to 4
Ω
allows the amplifier maximum power delivery. A higher impedance leads
to a reduction of the power delivered by the amplifier (e.g. 8
Ω
: approx. ½ power, 16
Ω
:
approx. ¼ power). An impedance lower than 4
Ω
overloads the amplifier.
-
Loudspeaker models shall be chosen by considering the max. power (240 W on a 4
Ω
load) 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.
