VOLUME LOCK
A special mention of volume control is warranted.
During typical computer use, volume is controlled within the operating system, and users can adjust
volume through many interfaces. While this is adequate for typical use, it presents a problem when
your concern is maintaining the integrity of digital audio data. The way in which the computer alters
volume is to remove data from the bit-stream, thus resulting in audio playback that is NOT bit-perfect.
There are two ways in which you can digitally affect the volume of playback—the master volume
control of the entire system, and the program volume in Media Player and Media Center. We offer the
option of locking both the master volume and the program volume to prevent accidental changes
(through pressing the control on the keyboard or remote, for example). When you choose to lock the
volume, the music files are not interrupted, and you simply control volume through your DAC or pre-
amplifier.
When you receive The Black Box™, the BitPerfect™ volume lock functions are disabled. To enable
these functions (i.e. to lock the volume), follow this two-step procedure:
1.
Open the Sample Rate Selector tool by clicking the icon in the lower right tray. Click on
“BitPerfect Volume Lock” and you will see a check
indicating your selection. This function will stay
enabled until you change it.
To verify, click on the Sample Rate Selector again;
it will be checked if enabled.
2.
You also need to make the change within Media Player:
Launch Media Player by clicking on the icon in the left lower tray.
Hit the "Alt" key and in the pop-up menu, click "Tools".
Click on “Plug-ins”.
Click on “BitPerfect™ Volume Lock”. When ”checked,” the volume within Media
Player and Media Center is also locked.
do I want bit-perfect and what is it anyway?
“Bit-Perfect” refers to the absolute perfect reproduction of the audio from its original source. Nothing is changed,
nothing is altered. Believe it or not, this is not the standard. Most systems, computers and consumer-electronic
devices modify the signal. This is done for many reasons—to apply effects; to mix in additional audio; and, in the
case of high-resolution music, to simplify the match required to play back files. All of these changes negatively
affect the quality of the music playback and need to be avoided. Great care has gone into the design of The Black
Box™ to ensure that all of your listening at native resolution is bit-perfect.
