Abstract:
A phantom power circuit has a detection circuit and a limiting circuit, the detection circuit detecting a pulse current generated in association with connection or disconnection of a condenser microphone, the limiting circuit limiting the output of the condenser microphone. The detection circuit detects a pulse current generated between input terminals of the condenser microphone. The limiting circuit reduces the output from the condenser microphone when the detection circuit detects the pulse current.
