Here, if the audio signal output to the analog audio output terminal 14 is zero for a
predetermined time, there is a high possibility that audio is not output to the Zone 2 room, the
AV amplifier 1 relates to the Zone 2 room mode. Even if an operation to be performed is received
and processing based on the operation is performed, there is no influence on the sound output to
the AV amplifier 1 installed in the Zone 2 room.
Therefore, in the present embodiment, when the audio signal output to the analog audio output
terminal 14 is zero for a predetermined time, the control unit 2 performs the subsequent
operation of the operation button 51 related to the Zone 2 room mode. Accept.
[0046]
In addition, when there is no operation of the remote controller related to the Zone 2 room mode
for a predetermined time, the AV amplifier 1 accepts the operation related to the Zone 2 room
mode because there is a low possibility that audio is being heard in the Zone 2 room. Even if the
processing based on the operation is performed, there is no influence on the sound output to the
AV amplifier 300 installed in the Zone 2 room. Therefore, in the present embodiment, when the
control unit 2 does not receive the operation of the remote controller 52 related to the Zone 2
room mode for a predetermined time, the control unit 2 receives the subsequent operation of the
operation button 51 related to the Zone 2 room mode. .
[0047]
As mentioned above, although embodiment of this invention was described, the form which can
apply this invention is not restricted to the above-mentioned embodiment, As it illustrates below,
it is suitably in the range which does not deviate from the meaning of this invention. It is possible
to make changes.
[0048]
In the second embodiment described above, the control unit 2 receives the operation of the
operation button 51 related to the Zone 2 room mode when the audio signal output to the analog
audio output terminal 14 is zero for a predetermined time. It is supposed to be.

Not limited to this, the control unit 2 may receive an operation of the operation button 51 related
to the Zone 2 room mode when the audio signal output to the analog audio output terminal 14 is
less than the predetermined value for a predetermined time. It may be done.
[0049]
In the above embodiment, the case where the AV amplifier 1 has the main room mode and the
zone 2 room mode has been described. Not limited to this, the AV amplifier 1 has two or more
analog audio output terminals, and has a mode (Zone 3 room mode) for outputting audio signals
to AV amplifiers installed in two or more rooms other than the main room. It may be done.
[0050]
In the above-described embodiment, the AV amplifier 1 outputs the audio signal input from the
content reproduction apparatus 100 to the analog audio output terminal 14 without
amplification or the like in the Zone 2 room mode. Not limited to this, the AV amplifier has a
speaker terminal in place of the analog audio output terminal 14, and when a speaker is
connected to the speaker terminal, the audio signal is amplified and output to the speaker. It may
be like that.
[0051]
The present invention can be suitably adopted for an audio processing apparatus that performs
audio processing such as amplification on an audio signal.
