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 44’s PCI controller chip.
As described in previous sections, the output of this mixer may be assigned to the
OUT1/OUT2 analog outputs. At the same time, the mixer outputs may be recorded
in stereo by software.
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
