An audio apparatus includes a network interface, a receiver, at least one storage, and at least one processor. The processor is configured to determine that the audio apparatus is in a state capable of communicating with the other audio apparatus via the network interface. The processor is also configured to receive audio data via the receiver transmitted from an external apparatus different from the other audio apparatus. The processor is also configured to output a sound based on the received audio data. The processor is also configured to transmit the sound emission control information stored in the at least one storage to the other audio apparatus. The sound emission control information includes one or more of a sound volume, and a frequency band.

Audio apparatus

An audio apparatus includes: a receiver which receives audio data transmitted by a broadcast method from an external apparatus; a sound emitter which performs sound emission of the audio data received by the receiver; a generator which generates sound emission control information relating to sound emission of other apparatus which can receive the audio data; and a transmitter which transmits the sound emission control information generated by the generator to the other apparatus.

An audio apparatus includes a receiver, a sound emitter, a generator, and a transmitter. The receiver receives audio data transmitted by a broadcast method from an external apparatus. The sound emitter performs sound emission of the audio data received by the receiver. The generator generates sound emission control information relating to sound emission of other apparatus which can receive the audio data. The transmitter transmits the sound emission control information generated by the generator to the other apparatus.

Under the control of a controller, a DSP supplies audio signals received from a switch circuit to a main zone DAC, subjects the audio signals received from the aforementioned switch circuit (i.e., audio signals for main zone use) to down-mixing processing so that the number of channels matches the number of output terminals assigned to each zone, and respectively supplies the audio signals subjected to down-mixing processing to the respective switch circuits of each zone. Each of the aforementioned switch circuits supplies the audio signals received from the subzone DAC to the respective volume adjustor of each zone.
