-
Loudspeaker models shall be chosen by considering the max. power (UP 2082: 80 W on
4
Ω
load, UP 2162: 160 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.
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 (UP 2082: 80 W,
UP 2162: 160 W).
Use 1 output only (either 100 V or 70 V or 4
Ω
) per amplifier (‘channel’)!
