* Pressing the PLAY button or the PAUSE button instead of the ENTER button
starts recording without locking in the setting.
* Please be aware that if you press the SELECT dial instead of the ENTER button, the
setting is not confirmed.
• The display of remaining time on the card available for recording
changes according to the selected RDAC-Grade.
• Next, if you're making the setting for "RDAC-Mode", you can proceed
to step 2 of the procedure for setting the RDAC-Mode.
RDAC-Mode (Signal Processing System)
The RDAC-Mode is a type of digital data processing system for recording.
On the AR-3000R, you can choose from among five types of modes.
fig.09-03e (RDAC Mode)
H-LINEAR :
24 bit PCM Recording
LINEAR
:
16 bit PCM Recording
MODE3
:
About 2.5 times the recording of Linear
* 1
MODE2
:
More than 2.5 times the recording of Linear
MODE1
:
About 4 times the recording of Linear
"H-LINEAR" enables recording at the highest sound quality, but uses the
most space on the card. "MODE1" uses up the least card space, and is suited
to long recording times. Select an RDAC-Mode that matches the
circumstances of use.
• If the type of card does not provide the recording time you want, change
the RDAC-Mode or RDAC-Grade setting to use less card capacity, then
perform recording again.
• Depending on the card type, an error may appear or recording may
stop. If this happens, change the RDAC-Mode or RDAC-Grade setting to
use less card capacity, then perform recording again.
