1. A microphone which comprises is a first microphone that is configured to connect to (i) an external device capable of supplying electric power and (ii) a second microphone, the first microphone comprising:
a first connection port configured for connecting to the external device;
a second connection port configured for connecting to the second microphone via a cable;
a synthesized signal output part configured for connecting to the first connection port and for connecting to the second connection port;
a determination part that:
is configured to determine to operate in a master mode, comprising supplying electric power through the second connection port to the second microphone connected via the cable, in response to a state wherein the cable is connected to the second connection port concurrent with electric power being supplied from the external device through the first connection port, and
is configured to determine to operate in a slave mode, comprising receiving electric power through the second connection port from the second microphone connected via the cable, in response to the cable being is connected to the second connection port concurrent with a state where no electric power is supplied from the external device through the first connection port;
a sound collecting part configured collect a sound from around the first microphone and transduce the collected sound into a sound signal;
a selection part configured to:
output to the synthesized signal output part the sound signal input from the sound collecting part and a slave sound signal received from a slave signal output part of the second microphone, in response to receiving an instruction for operating in the master mode from the determination part, and
output the sound signal, input from the sound collecting part, to the slave signal output part that outputs to the second microphone, in response to receiving an instruction for operating in the slave mode from the determination part.
