Q I cannot hear my voice through the built-in microphone. A This is because the setting is configured so that sound from the built-in microphone to the speaker is muted to reduce the howling sound effect. You can use the microphone recording function normally, even in this state. When using an external microphone, if you disable the microphone channel mute function of the play mixer, you can hear the sound input into the external microphone through the speaker. Q I have a trouble with recording after selecting 'Acoustic Echo Cancellation' and unselecting Mute in the Microphone volume of the Playback Mixer. A This is because the sound from the external microphone is muted by the Acoustic Echo Cancellation Algorithm considering the sound as a Acoustic Echo while the recording and playing back is processed at the same time. In this case, select Mute in the Microphone Volume of the Playback Mixer after selecting Acoustic Echo Cancellation item. 162

Q
I cannot hear my voice through the
built-in microphone.
A
This is because the setting is
configured so that sound from the
built-in microphone to the speaker is
muted to reduce the howling sound
effect. You can use the microphone
recording function normally, even in
this state.
When using an external microphone,
if you disable the microphone channel
mute function of the play mixer, you
can hear the sound input into the
external microphone through the
speaker.
Q
I have a trouble with recording
after selecting ‘Acoustic Echo
Cancellation’ and unselecting Mute
in the Microphone volume of the
Playback Mixer.
A
This is because the sound from the
external microphone is muted by
the
Acoustic Echo Cancellation
Algorithm considering the sound as a
Acoustic Echo while the recording and
playing back is processed at the same
time. In this case, select Mute in the
Microphone Volume of the Playback
Mixer after selecting
Acoustic Echo
Cancellation
item.
