With the jumper on X300 the kit can be adapted to
the type of microphone.
With the jumper connecting pin 1 and pin 2 of X300,
a dynamic microphone can be connected to X301,
e.g. LBB9081 and LBB9082.
With the jumper connecting pin 2 and pin 3 of X300,
an electret condenser microphone can be connected
to X301. In this mode, pin 1 and pin 3 of X301 will
have a 12 V phantom power supply.
