When all the connectors are used at the same time, priority is given in

the order shown below:

Audio modesAudio modes

Audio modes

48kHz/16-bit mode

Records 16-bit stereo audio data 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 TwinPact 100 records audio data, it is recorded only on the 2

main channels and no sound is recorded on the 2 sub-channels.

Unlocked mode

Unlocked audio in consumer products are allowed to have some devia-

tion in the number of audio samples per one video frame. If this devia-

tion is accumulated along with elapsed time, however, it results in

sound drift.

On the other hand, the Locked Audio mode ensures 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

recorded 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 Unlocked mode available for your use.

The Locked Audio feature is ef-

fective only in analog-to-digital

conversion.

Tip

This product supports copyright protection technologies such as copy-

prevention technology. If the TwinPact 100 receives data with copy-

prevention signals attached, it outputs the data with extremely low

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