Audio signal input and output device, audio system, and audio signal input and output method
An audio signal input and output device includes a port that inputs or outputs an audio signal, an interface that receives a specification of a channel or bus to be assigned to the port, and a sender that sends information over a network for assigning the channel or bus based on the specification received by the interface. The information assigns the inputted audio signal to a predetermined input channel of the management device. A speaker emits a sound based on the inputted audio signal.
1. An audio system comprising:
an audio signal input and output device comprising:
a port to input an audio signal or to output an audio signal;
an interface to receive a specification of a channel among a plurality of channels to be assigned to the port, or to receive a specification of a bus among a plurality of buses to be assigned to the port; and
a sender to send information assigning the channel to be assigned or the bus to be assigned to a management device based on the received specification, wherein
the port inputs or outputs the audio signal on the channel assigned by the management device based on the information, or on the bus assigned by the management device based on the information; and
the management device comprises:
a receiver to receive the information from the audio signal input and output device; and
a processor to assign the port to the channel or the bus that corresponds to the port based on the received information.
2. The audio system according to claim 1 , wherein
the information assigns the audio signal inputted from the port to a predetermined input channel of the management device.
3. The audio system according to claim 1 , wherein
the information is sent to the management device through a network.
4. The audio system according to claim 1 , wherein
the information includes an IP address of the audio signal input and output device to input or output the audio signal; and
the management device stores the IP address corresponding to the input channel or the output bus.
5. The audio system according to claim 1 , wherein
the information includes an IP address of the audio signal input and output device to input or output the audio signal; and
the management device stores the IP address corresponding to the channel or the bus.
6. The audio system according to claim 1 , wherein
the information includes an IP address of the audio signal input and output device to input or output the audio signal; and
the management device stores the IP address corresponding to the channel or the bus.
7. The audio system according to claim 1 , wherein the processor is further configured to:
receive an inquiry from the management device, and
send the information in response to the inquiry received from the management device.
8. The audio system according to claim 1 , wherein
the port is a first port; and
the audio signal input and output device further comprises:
a second port to input an audio signal or to output an audio signal, wherein
the input channel or output bus assigned to the first port is different from an input channel or output bus assigned to the second port.
9. The audio system according to claim 1 , wherein the port is configured to:
receive an input audio signal; and
send the input audio signal to the management device.
10. The audio system according to claim 1 , further comprising:
a speaker to emit a sound based on the inputted audio signal.
11. The audio system according to claim 10 , wherein
the information assigns the inputted audio signal to a predetermined input channel of the management device.
12. The audio system according to claim 1 , wherein the information is sent through a network.
