When all the connectors are used at the same time, priority is given in
the order shown below:
• Video
1. S-video input
2. Composite input
48kHz/16-bit mode
In this mode, audio data is recorded as 16-bit stereo sound at 48 kHz.
Select this option when you create DVD videos.
32kHz/12-bit mode
In this mode, 4 channels of 12-bit audio signals are recorded at 32kHz.
When ADVC-300 is used for recording, audio data is recorded in only
the 2 main channels and no sound is recorded in the 2 sub-channels.
Unlocked mode
Unlocked audio in consumer products are allowed to have some
deviation in the number of audio samples per one video frame. If this
deviation is accumulated along with elapsed time, however, it re-
sults in sound drift. On the other hand, the Locked Audio mode en-
sures synchronization between audio and video by restricting the
number of audio samples per one video frame in accordance with a
preset pattern, thereby sound drift does not take place. When the
Locked Audio mode is used for capturing from a video source with
highly irregular signals such as game machines, however, the re-
corded sound may contain noises because incoming signals exceed
the limit for regulating the number of audio samples in accordance
with the locked audio pattern. For that reason, we made the Un-
locked mode available for your use.
