LOUDSPEAKER CONNECTION

Use 1 output only, DO NOT MIX 100 / 70 V and 4 Ω CONNECTIONS !

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.

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

(80 W) 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.
