Setting up the system
ATTENTION
Make sure the power of the device is turned OFF before any connections or wiring adjustments are made.
Disregarding this rule can lead to permanent damage of the equipment.
1) Connecting the loudspeakers
The loudspeakers should be connected to the 4-pin terminal block connector on the rear panel of the amplifier.
Selection can be made between low impedance or constant voltage (100V / 70V) depending on project requirements.
The corresponding terminals and settings shall be connected depending of the loudspeakers and installation type.
The table below shows the output voltage, impedance and maximum power load for each amplifier model.

For operation in low impedance mode, any loudspeaker (or combination) with an impedance higher or equal to 4

can be connected.

loads. This might look
uncommon and strange, however these figures are true and correct. The output voltage is increased at higher
load impedances to guarantee the maximum output power is achieved. These figures are depending of a correct
output setting configuration in the ‘Settings’ > ‘Amplifier’ > ‘Output’ and ‘Output type’ menu.
For use in constant voltage (100V / 70V ) audio distribution systems, all speakers shall be connected in parallel on
the corresponding output terminals, non exceeding the maximum wattage / minimum impedance of the amplifier.
