The condition of an AX16 is indicated by its own ALIVE contact. In addition, a status contact (ACTIVE) is

available which triggers in case of the activation of the backup ampliﬁer/mode.

Caution

In case the mains supply fails, the AX16 (ALIVE contact will open) will fall back into a safety

mode: all signals are directly switched to the ampliﬁer inputs and the ampliﬁer outputs are

directly switched to the loudspeaker outputs. The digital potentiometers are bridged and the

signals are switched without level control.
