For the SF 3CT LP only

, set the rotary tap selector switch to the appropriate setting

using a small screwdriver.

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.
