ABSTRACT:
When a plug of a monaural microphone is connected to an external microphone input section, a right channel terminal is connected to a GND terminal, and a voltage Vdet will be a GND potential. A DC voltage detection section detects this GND potential, and outputs, for example, an H level signal as a detection signal. In response to this detection signal, a system control section controls a DSP so that, for example, an audio signal of the left channel is recorded by use of both right and left recording channels.
