ATTENTION:

• When setting the taps for a distributed (high impedance) system, do not tap

the system above the rated power of the amplifier.

• Lors de la mise en place des capteurs pour un système distribué (haute

impédance), n’exploitez pas le système au delà du niveau d’alimentation de l’ampliﬁcateur.

• When connecting multiple speakers in 8-ohm mode, be sure that the

combined rated impedance does not equal a value less than the minimum rated impedance of the amplifier.

• Lors de la connexion de plusieurs enceintes en mode 8ohm, assurez vous que

le niveau d’impédance combinée ne soit pas équivalent à une valeur inférieure à l’impédance minimum de l’amplificateur.

5. Install the grille. Position the grille so that it covers the baffle of the speaker. Six small

magnets secure the grille in place.
