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 overload and audio clipping may occur. Therefore be

careful to adjust the incoming audio levels so that they do not peak in the

red section too long (you might use the monitoring capability of the Delta

R-BUS to let your ears be the judge). On all output level meters, 0dB

indicates full-scale output. Unlike the inputs, clipping is impossible on

the outputs because of the 36-bit resolution built into the mixer hardware.

MASTER VOLUME

At the left side of the Monitor Mixer page, you will see the ‘Master

Volume’ faders and peak meters. These faders have the longest ‘throw’

and highest meter resolution of any level controls in the mixer page.

They control the overall stereo level of the mixer output. The peak meters

indicate the output signal levels with respect to full-scale and are directly

affected by the settings of the master volume faders.

MIXER INPUTS: The ‘Mixer Inputs’ are inputs to the monitor mixer.

These inputs accept hardware audio streams (directly from the Delta’s

R-BUS input ports and analog or the S/PDIF digital input port) and

software audio streams (digital audio generated in software to be

output). This combination of streams makes the monitor mixer extremely

flexible. Each mixer input channel has its own level fader and may be

panned anywhere in the left/right stereo field. Each input also has its

own peak meter. The peak meters indicate the incoming "pre-fader"

levels of the incoming audio, and are therefore not affected by the fader

settings. However, the input faders do affect the levels of the signals

exiting the mixer and you will see the affect of the input faders on the

output "Master Volume" peak meters.

Because of the large number of mixer inputs, not all inputs are displayed

simultaneously. You may use the scroll bar at the bottom of the Delta

Control Panel to scroll the view left or right. On the PC, from far left to

right the inputs are labeled "WavOut 1/2" through "WavOut 7/8," then

"WavOut SP/ANA." These inputs accept the digital audio streams being
