M-AUDIO DELTA 66 - Manual (Page 17)

The Monitor Mixer Page is essentially a collection of volume level faders, audio
level (or ‘peak’) meters, and solo/mute controls. For each mixer output and input
channel there is one of each: a volume fader, a peak meter, a solo control, and a mute
control.
LEVEL FADERS: Each volume fader may be controlled by dragging its fader
‘handle’ vertically with the mouse, or by clicking on the ‘handle’ to make it active
and then adjusting it with the up/down cursor keys of your computer keyboard.
Because the mixer has no gain, these faders only attenuate (reduce) the signal levels.
The highest setting is 0dB, or ‘Unity Gain.’ The default fader setting is the quietest
setting, –144dB, which essentially mutes the audio. A pair of level faders may be
“ganged” so that both channels may be adjusted together as a stereo pair.
Also, at the top of each fader and meter is a fader level “fine adjustment” control.
Clicking on the small “up” and “down” arrows will adjust the corresponding fader
setting in 0.5dB increments. Next to each fine adjustment control is a numerical
fader readout that is always current and active.
PEAK METERS: Each peak meter indicates an audio signal level in “dB relative to
full-scale.” This means that a full-scale signal is referred to as “0 dB” and a signal
that is 12dB ‘quieter’ than full-scale is referred to as “-12dB.” The meters are
vertically color-coded into three sections: green, yellow and red. The green section
represents a safe zone, ranging from approximately -48dB to -12dB. Most audio
signals should appropriately fill this section of the meter. The yellow section ranges
from -12dB to -3dB as the signal approaches a ‘hotter’ level. For best capture
resolution, recording in this area is both safe and advised. The red section of the
meter ranges from -3dB to 0dB. On the input level meters, a 0dB condition indicates
