Priorities among analog input signals

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.

This product supports copyright protection technologies such as copy-

prevention technology. If the ADVC-300 receives data with copy-pre-

vention signals attached, it outputs the data with extremely low bright-

ness and contrast. The STATUS LED will light to indicate this.
