Connection

This speaker operates with constant voltage and is therefore suitable for connection to 100V systems. Make sure to connect the speaker's black terminal to the "COM" socket of the amplifier, while the speaker's red terminal is to be connected to the 100V socket of the amplifier. Your speaker offers the possibility to choose the desired power (RMS 2,5W -5W- 10W).

If you need to connect more than one speaker, after checking the total power, you can connect them to the amplifier with "parallel" wiring. (fig.1).

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

Consider carefully the power of the speakers and of the amplifier they are connected to: the total power of the speakers must not exceed the amplifier's power.
