CONNECTIONS, CONTROLS AND INDICATORS:
9 LED INDICATORS
POWER: Lights up once the system is properly connected to the power mains and switched on.
SIGNAL: Lights up as soon as an audio signal is present.
LIMIT: Lights up if the loudspeaker system is operating in the clipping range. A short flash of the LED is not
critical. To protect the system, an excessive signal level is gently turned down by the built-in limiter. If the
Limiter LED lights up permanently or for longer periods, reduce the volume level. Failure to do so may result
in a distorted sound and damage to the speaker system.
PROTECT: Lights up if the system is overloaded/overheated. The amplifiers are muted automatically. After
reaching normal operating conditions, the device reverts to normal operating mode, after a few minutes.
10 IEC POWER SOCKET WITH INTEGRAL FUSE HOLDER
Used to power the device. An appropriate power cord is included in the delivery.
IMPORTANT INFORMATION: The speaker is intended for 2 operating voltage ranges (110 V - 120 V AC and
220 V - 240 V AC). The conversion is done automatically.
Replace the fuse only with a fuse of the same type and rating (see label on the rear panel)! If the fuse blows
repeatedly, please contact an authorised service centre.
11 POWER
On / Off switch for the power supply of the device. Before switching the active speaker on or off, always
