Pressure sensor
In order to guarantee high system performance, the
proper placement of the pressure sensor on the loudspeaker
cabinet and the correct connection of the transducer to the
M-Drive are paramount.
WARNING!
Inadequate or wrong positioning of the
pressure sensor can easily damage the amp
module and the loudspeaker permanently.
The pressure sensor must be mounted on the front side
of the loudspeaker cabinet as close to the diaphragm as
possible.
The protruding black cylinder must be inserted in a 10
mm hole.
Note the polarity in the 3 possible configurations:
1. If both the motor and the pressure sensor are mounted
inside the cabinet, pointing outwards, follow the speci-
fied polarity when connecting the M-Force.
2. If the motor is mounted outside the cabinet and point-
ing inwards, and the pressure sensor is mounted in-
side the cabinet, pointing outwards, reverse the speci-
fied polarity when connecting the M-Force.
3. If both the motor and the pressure sensor are mounted
outside the cabinet, pointing inwards, follow the speci-
fied polarity when connecting the M-Force.
