SUBPHASE 0° / 180°
The phase reverse switch for the subwoofer (0°, 180°) is factory set to 0°. This setting is suitable for the
majority of applications. In unfavourable acoustic conditions, the setting of 180° may have a positive effect
on the overall sound. If the DSP MODE switch is in position SLAVE (MAUI44), this feature is disabled.

DSP MODE
MANUAL: If the MAUI44SE subwoofer is to be used as stand-alone PA subwoofer, set the switch to the left
position MANUAL. The connectors LINE INPUT LEFT / RIGHT, and LINE OUTPUT LEFT / RIGHT can now be
used to connect playback devices and to control other active speakers or amplifiers. Also, the SUB LEVEL,
SUB FREQ and SUB PHASE controls can be used for customised settings.
SLAVE (MAUI44): If the MAUI44SE subwoofer is used as an extension for the MAUI44 column system, set the
DSP MODE switch to the right position SLAVE (MAUI44) and connect the line output SLAVE SUB OUT (MAUI44SE)
of the MAUI44 column system with the line input SLAVE SUB IN (MAUI44) of the MAUI44SE subwoofer. If the
switch is in SLAVE position (MAUI44), the SUB LEVEL, SUB FREQ and SUB PHASE controls , as well as the left
line input LINE INPUT LEFT are disabled.

INDICATOR LEDS
ON: 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. The signal acquisition is performed before the MAIN
LEVEL controller.
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. Upon
reaching normal operating conditions, the device reverts to normal operating mode, after a few minutes.
