Recording with the internal microphone

fig.mic-LR.eps
The R-1's internal microphone is stereo. Audio entering
the microphone at the right side of the R-1 is recorded
on the right (R) channel, while the audio picked up by
the left microphone is recorded on the left (L) channel.
If you want to use the internal microphone,
don't connect anything to the mic input jack or
line input jack.
If a microphone or cable is connected to the mic
input jack or line input jack, these inputs will
take priority, and the internal microphone will
not be used.
1
Make sure that the R-1's power is turned off. Also set the input volume to the
minimum position.
If you want to hear (monitor) the sound while recording from the internal
microphone, connect a set of headphones to the phones jack and use them for
monitoring. If you connect external speakers and attempt to use them for
monitoring, acoustic feedback will occur, so don't attempt to monitor through
speakers.
