Connecting 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.
For operating using 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
The loudspeakers should be connected to the 4-pin terminal
block connectors on the rear panel of the amplifier. Selection
can be made between low impedance (4
Ω
) or constant
voltage (100V / 70V) depending on project requirements.
The corresponding terminals and settings shall be chosen
depending of the loudspeakers and installation type.
The table below shows the output voltage, impedance and
maximum power load per channel for each amplifier model.
For operation in low impedance (4 ohm) mode, any
loudspeaker (or combination) with an impedance higher or
equal to 4
Ω
can be connected.

Depending on the chosen connection method (low
impedance or constant voltage), the output configuration
setup shall be configured accordingly.
Do not connect high and low impedance speakers to one
output at the same time.
