The installation of this product must be carried out exclusively by specialized technicians, skilled in electric and audio systems.

In case of wrong installation or connections, the manufacturer doesn't take any responsibility for damages to people or objects.

Refer to the below picture (pict.1) for correct cable connection. Before starting the installation make sure that the amplifier is turned off.

WIRING

For connection insert the "+" and the "-" wire into output terminals of the amplifier, respecting the indicated polarities.

If you need to connect more than one speaker, after checking the total power, you have to make series or parallel wiring (see example in pict. 1), to obtain a final impedance supported by the amplifier (usually 4-16Ω).

Wrong impedances can seriously damage the connected fixtures.

Remember to consider the correct section of the cables, according to the distance of the speakers from the amplifier.

Consider carefully the total power of the speakers, which must correspond more or less to the amplifier's power.
