that manages to get into the audio signal is an example of what the High Pass Filter
can remove, and it is quite effective at reducing or removing such noises without
impacting the musicality of the programming.
Output Level dBFS
The Output Level meter scale is calibrated in dBFS (decibels Full Scale) a com
-
mon scale for digital audio equipment. The top of the scale represents 0dBFS, the
point where there are no more digital bits available to define further increases in level.
Trying to exceed this level will not allow the audio to increase any further and it will
become clipped and severely distorted.
The processing structure of the Aura8ip manages the peak levels applied to the
Output level control. Therefore, unlike the input meter where we want to stay below
-12dBFS, the Output meter can be pushed all the way up to 0dBFS without fear of
distortion.
An exception to this statement – when the Final Peak Limiter is not used the Out
-
put Control must be operated in a way that leaves some headroom above the meter’s
maximum peak indications … “just in case.”
Taking Presets
Aura8ip is equipped with over two dozen Factory Presets and we recommend
listening to each preset with typical programming to find the one that best meets your
needs. Select the preset closest to the desired sound texture and use the six processing
tweakers of the Guru GUI to ‘dial it in’ if necessary.
When the GUI’s Preset button is pressed a dialog
will open (see left) with a list of the presets cur-
rently stored on the Aura8ip hardware. Presets are
put into use by double-clicking them.
Note that the presets in the list are shared between
the eight processors inside the Aura8ip –
every preset
is available to every processing channel. The same
preset can also be used on multiple channels at the
same time. Likewise, any user preset that has been
created for one processing channel may be used on
any other processing channel.
Note: unlike other Wheatstone products with
Embedded Vorsis Processing™ the Aura8ip does
not have just one Quick Start preset. Rather, it has
three:
- Quick Start_1band
- Quick Start_2band
- Quick Start_3band
We believe these presets are good basic starting
points for each of the three processing structures.
They may be used as is, or modified using the Guru
GUI’s six tweaker controls and then saved as new
presets if desired.
