M-AUDIO Delta RBUS - Manual (Page 20)

Monitor Mixer Page
The Monitor Mixer is the first page that appears when the Delta Control
Panel is opened, and controls the digital mixer built into the Delta
R-BUS’s PCI controller chip. As described in previous sections, the output
of this mixer may be assigned to the OUT1/OUT2 R-BUS outputs, and to
the Analog and S/PDIF outputs simultaneously (this selection is made in
the Patchbay Router page). At the same time, the mixer outputs may be
recorded in stereo by software by selecting “Mon. Mixer”as the audio
source for a given track.
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 the 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 "linked" 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.
