Some condenser microphones used for video field re-
cording, such as the Sennheiser 416T, require T12 (AB-
12V) power. The FM-3 can supply the T12 power.
Unlike the phantom power (P48), connecting a dynamic
microphone to the input channel where the T12 power is
supplied may destroy the microphone. To prevent such
an accident, you can disable the T12 power supply func-
tion. If you do not use the T12 power supply function in
your circumstance, it is recommended to disable the T12
power by following the procedure below. When shipped,
the T12 power supply function is disabled.
