To start/stop recording in
sync with the source player
(Synchro-recording)
You can easily make digital recordings of
a digital source on an MD.
Before synchro-recording, make

Digital recording is possible even from
digital equipment with different sampling
rates, such as a DAT deck or a BS tuner,
using the built-in sampling rate converter.
1Insert a recordable MD and start
recording.
For recording operations, see
