Operating permit
The use of wireless microphone systems
is generally subject to local licencing or
permit arrangements. For further details
contact your local Sennheiser distributor.
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!).
