M-AUDIO DELTA 1010 ユーザーズマニュアル

 

Monitor Mixer is the first tab that appears when the Control Panel is opened. 

This tab controls the digital mixer built into the Delta 1010 PCI Host Adapter card and 
has the following controls and indicators:

<   

LEVEL FADERS:  Each volume fader is controlled by dragging the vertical 
slider with your mouse, or by clicking on the small up and down arrows above 
the faders (these “fine adjustment” arrows will raise or lower a fader in 0.5dB 
increments).  The current fader setting is displayed numerically above each fader.

 

 Note that the Monitor Mixer has no gain and that its faders only attenuate 
(reduce) incoming signal levels once the signals have been converted to digital 
audio. The highest setting is 0dB (or ‘Unity Gain’) and allows signals to pass 
through unaffected.  The default fader setting (-144dB) is the quietest setting and 
will essentially mute the channel.

<   

VU METERS:  Each channel features a VU meter that indicates audio levels in 
“dB relative to full-scale.” This means that the loudest possible signal is referred 
to as “0dB” and a signal that is, for example, 12dB lower than the maximum 
loudness is referred to as “-12dB.” 

 

 The meters are color-coded into three sections: green, yellow and red. The green 
section represents the “safe” zone and ranges from approximately -48dB to -
12dB.  The yellow section ranges from -12dB to -3dB, and the red section ranges 
from -3dB to 0dB.  Once a signal reaches (or exceeds) 0dB, it means the signal 
is overloading Delta 1010’s analog-to-digital or digital-to-analog converters and 
is “clipping” or distorting.  Unlike the analog distortion found on guitar amplifiers 
and effects pedals, digital distortion is harsh, unmusical, and should generally be 
avoided.

 

 Therefore, we recommend setting input and output levels so that the loudest 
peaks of your incoming signal will reach the top of the yellow range but will
