4.3 CD-R (4X) strategy
----------------------
The write state will be changed by varying the laser power and its radiation duration of the drive. As a result, the sound quality or read performance may fluctuate depending on the congeniality of the media and the drive. The change may work better or worse. It is impossible for TEAC to make a verification as it depends on the congeniality of the media and the drive. Changing the settings is your own responsibility.


These settings function only for the CD-R media and only when the write setting is 4X speed. Set the write speed to 4X using a writing application.

<Normal>
Default settings adjusted by TEAC
<Boost>
The media is written with stronger laser emission in a lesser time than those of the normal settings.

* Normal is selected in the default settings.
* Note in advance that some effects may not be noticeable or a side effect such as increasing errors may result when Boost is selected.

懶的全翻了，大意就是開啟Boost會在燒錄過程中使用更強的雷射功率、在較短的時間內燒錄。品質不一定會更好或更差，TEAC不保證開啟此功能的後果...........
