Changing the phase
Ex works the phase has been preset in
such a way that a positive pressure pulse
at the microphone membrane produces a
positive signal at the receiver output.
After the sound inlet has been removed
the position of capacitor C 3 can be
changed, thus reversing the phase (see
illustration).
Reversing the phase of the SKM 4031 Tv:
Solder C 3 between socket 2 and 3
(+pole into socket 2).
Reversing the phase of other models:
Insert C 3 into the holes close to the
capacitor and solder together (pay atten-
tion to the polarity!).
Operating permit
The use of wireless microphone systems
