GENERAL INFORMATION
General Information
Introduction
The Aura8ip is the newest member of the Wheatstone WheatNet‑IP Intelligent Net‑
work family of devices. It is really two devices in one package; a complete WheatNet‑IP
Blade with 8x8 stereo I/O and a Vorsis 8‑channel multi‑band audio processor.
WheatNet‑IP Blades are the Swiss Army knife of audio routing, with local audio
inputs and outputs, GPIO ports, built in router control, mixing, meters, monitoring, and
a host of the other functions. Blades can operate as stand alone devices or be linked
via gigabit Ethernet as part of an IP audio network.
As a member of the WheatNet‑IPBlade family, the Blade functionality of theAura8ip
is described in detail in the Wheatnet‑IP Audio Over IP Network manual supplied with
the unit. In the Wheatnet‑IP Audio Over IP Network manual you’ll learn how to set up
the device ID and IP address, and learn how to use all of the Blade features built into it.
The Vorsis processing features of the Aura8ip are unique to this unit and deserve
their own documentation, which follows here. Use this document to learn all about
the processing capabilities the Aura8ip has and how to control them with the included
GUI application.
The WheatstoneAura8ip “Vorsis Embedded” Processing Blade hosts eight discrete
multiband audio processors. Because Aura8ip may be operated in stand alone or as
part of a Wheatnet‑IP system of any size, any available audio signal can be routed thru
the Aura8ip to apply easy to use audio processing before the audio reaches its nal
destination.
The Aura8ip’s eight channels of multiband processing have the following features:
• Audio input and output audio via analog, digital, and Wheatnet-IP;*
• Selectable high pass lter which operates in the L/R or M/S domain;
• Phase rotator for smooth processing of live voice;
• Input channels may be phase reversed or channel swapped;
• Input channels may be operated in a mono mix down mode;
• Four band equalizer with shelving and parametric sections;
• Multiband AGC/Compressor with one, two, or three bands of processing per
channel;**

GENERAL INFORMATION
• Parametric EQ with adjustable crossover networks;
• Stereo enhancement;
• Multiband limiter with one, two, or three bands of limiting per channel;**
• Selectable Vorsis bass enhancement;
• Final peak limiter with selectable lookahead function;
• Full complement of factory processing presets;
• Storage in the hardware for up to 80 presets.
* 50/50% mix of analog and digital I/O plus WheatNet-IP on all channels.
** The number of limiter bands always follows the selected number of AGC/Com‑
pressor bands.
Aura8ip’s exibility allows each processor to be operated in three bands, two bands,
or as a broadband (one band) processor.
Each of the Aura8ip’s processing blocks (AGC, Compressor, EQ, Limiters) may be
enabled or disabled as desired. Each of the eight processing instances shares a library
of up to 80 presets stored on the Aura8ip hardware. Several dozen “Factory” presets
supplied with the unit provide good starting points that have been tuned for a variety
of needs. Presets stored on any Aura8ip may be shared with any other Aura8ip on the
network.
Preset Transitions
As with all Vorsis audio processors, changing from one preset to another doesn’t
abruptly change the audio, nor are clicks and pops generated during those changes.
Instead, presets “segue” from one to another, causing a gradual change in sound as the
parameters are slewed from their old to their new settings over the course of two seconds.
Some prefer hearing radical, easy to identify changes when a preset is recalled.
However, this is usually the least desired behavior when presets change in actual on‑
air use. Since that mode is the most important mode – it’s what an audience hears – we
designed preset changing to be as unobtrusive as possible for listeners.

Aura8ip Audio Processing Overview
The following block diagrams show the internal structure of the Aura8ip Process‑
ing Blade.
The rst graphic shows how four of the eight processors are equipped with analog
I/O and four are equipped with digital I/O when run in stand alone mode, and all eight
are equipped with Wheatnet‑IPaudio inputs and outputs when run in networked mode.

Note: EQ may be placed pre or post AGC/Compressor
Installing the Aura8ip Blade
Aura8ip is designed to be mounted in an industry standard 19" equipment rack,
and requires one rack unit (1.75 inches) of vertical space. The Aura8ip BLADE has a
depth of 13-1/4" behind the rack rails (including chassis connectors). An additional ve
inches of space is required for wiring cables to pass through. The chassis has a width of
17‑3/8". Space needed in front of rack rails is 3/4". Ideally, four screws should be used
to mount the unit. If only two screws are being used they must be used in the bottom
holes in order to provide proper support.
Though Aura8ip does not add much heat load to the rack that it is installed in, good
engineering practice suggests that it should never be mounted directly above a large
source of heat such as a power supply or RF amplier. Strong electromagnetic elds
should also be avoided.
Energizing the Aura8ip Blade
Once it has been installed in the rack, the Aura8ip BLADE may be energized by
connecting the factory supplied power cord to a source of AC power. For long term
reliability, there is no power switch on the Aura8ip (rarely used switches are notoriously
unreliable). When the Aura8ip rst powers up, it will enter “Stand alone” mode. This
is the mode that would be used if the BLADE were not part of a Wheatnet‑IP system.

GENERAL INFORMATION
I/O Connections
All input, output, Ethernet, control and power connections are made on the rear
of the Aura8ip Blade.
The audio I/O connections are via DB-25 or RJ-45 connectors on the rear of the
unit, and the two types of connectors are electrically in parallel.
There are two RJ-45 connectors associated with networking, one Gigabit port
and one 100BaseT port. Only the Gigabit port is currently supported.
Refer to the Chapter 1 of the Wheatnet‑IP Audio Over IP Network manual for
detailed wiring information.
Cable Considerations
The AES Digital input and output connections should be made with high quality
digital audio cable. Typical AES/EBU cable has low capacitance per foot (pF/ft) and
a nominal impedance of 110 ohms.
Avoid using run-of-the-mill analog audio cable for AES digital signals because
this type of cable may have an impedance of 60 ohms or less and can cause problems
in medium length cable runs and severe signal recovery issues on long runs. Like in
the RF world, using the proper impedance cable is critical to obtaining the best and
most reliable performance. Check with your favorite cable manufacturer to ensure
that the cable you have chosen will work for you.
Connectors
All connections other than AC power are made thru rear panel DB-25 connectors
and/or RJ-45 connectors. The DB-25 crimp style connector pins will accept wire
sizes 22 through 28AWG. For the RJ-45 audio connections Wheatstone recommends
using XLR to RJ-45 adapters at the source (to the Blade) or at the destination (from
the Blade) and to provide a proper strain relief for those adapters. Obviously using
RJ-45 to XLR adapters can also be done on the back of the Blade, too, but doing it
this way might make things a bit crowded.
When using a stereo XLR to RJ-45 adapter for AES digital signals only the XLR
connector for channel one is used.
The Aura8ip will accommodate digital input signals with a wide range of sample
rates. Those signals will be sample rate converted to the Aura8ip internal sample
rate of 44.1 or 48kHz, which is set for the WheatNet-IP system, or for a stand alone
Aura8ip, using the Navigator GUI.

Aura8ip GURU GUI
Vorsis Aura8ip Guru®GUI
Supplied with every Aura8ip processor is our Vorsis Audio Processing Guru®
software (Guru GUI), which drastically simplies processing adjustments and allows
the processor to be controlled from anywhere in the world. The Guru GUI distills
the Aura8ip’s 93 user controls per processing channel down to just six intuitive and
easy to use controls.
Guru GUI makes setting the sound of the processing quick and efcient and allows
the managing of processing presets. Finding the perfect sound has never been easier!
Presets created on one Aura8ip can be migrated to other Aura8ip units via the
built-in preset management utility.
Condence metering along the bottom of the GUI provides visual feedback of all
eight channels of the input and output signals and their relative levels.
Installing the Guru Software
The Guru software is provided on a software CD shipped with the product and
once installed, grants easy access to Aura8ip’s vast sound processing capabilities.
Installing the software is easily done using the following procedure:
• Insert the Aura8ip software CD into a Windows computer;
• Click the Start button;
• Click the Run option;
• Click the Browse option;
• Browse My Computer to locate the CDROM device and double click it;
• When the contents of the CDROM drive appears, locate the Aura8ip_exe le
and double click it to start the GUI installation;
• Follow the on screen instructions to complete GUI installation.
Conguring the Aura8ip TCP/IP Address*
Once the GUI has been installed on the host PC it must be congured before it
can connect to and control the Aura8ip processor. Note also that as shipped, the fac-
tory default IP address of the Aura8ip is 192.168.87.101. This address can be viewed
and/or changed from the front panel if necessary, remembering that rebooting the
Blade will be necessary if the IP address and/or the Blade number are changed.

page 2 - 3
Aura8ip / Jan 2012
Aura8ip GURU GUI
Next, start the Aura8ip GUI software and use the following procedure to congure
it to be able to connect and control the Aura8ip processor.
• On the right hand side of the GUI, click on the Devices button, then click the
Add... button; the above dialog will open.
• Insert a name for the Aura8ip. This is the name that will be displayed at the
top of the GUI to inform the user which processor he is currently connected to.
• Next enter the IP address of the Aura8ip, keeping in mind that if the address has
not been changed from the Factory Default, that IP address is 192.168.87.101.
• Click the OK button to close the dialog.
• Highlight the newly congured device and click the Select button.
If there is a network connection between the
GUI’s host PC and the Aura8ip processor, and the
PC is congured to be on the same network subnet
as the processor, the Online button at the top left
of the GUI may be clicked to connect to the pro-
cessor. When the GUI is online to the processor
and controlling it, the green indicator inside the
button will be illuminated and the Status window
will display “Online.”
IP Address Note: Unless special routing has been congured by the IT depart-
ment the controlling PC and the Aura8ip must be on the same network subnet. As
an example, if the Aura8ip has an IP address 192.168.87.1, then the PC’s IP address
must be congured to be between the addresses 192.168.87.1 and 192.168.87.254,
noting that the Aura8ip and the host PC cannot share the same IP address.

page 2 - 4
Aura8ip / Jan 2012
Aura8ip GURU GUI
* NOTE: TCP port 55901 must be open in any switch or router conguration in
order to permit network trafc between Aura8ip and the controlling GUI.
Once the GUI is online with the processor the GUI’s controls become active and
may be used for adjusting levels, taking presets, and tweaking the sound of processing.
Selecting the Processing Channel
Across the top of the GUI are eight buttons representing the eight multiband
processors of the Aura8ip. The channel currently being viewed is shown by an il-
luminated green indicator on the left side of the button.
Adjusting the Controls
Input Level
To achieve the best sound and performance from any audio processor the correct
setting of the Input Levels is important. If levels are too low the processing settings
may not operate as they were designed. For instance, if a factory preset is in use
and the input levels are too low the multiband
AGC could stay in its gated mode when it
shouldn’t, reducing the effectiveness of the
processing. Conversely, if input levels are
too high, distortion can result on audio peaks.
Input levels are correct when the Input
meters are just nudging the -12dBFS Ref mark
on the Input meter scale (see left).
Setting up to operate with input levels
higher than -12dBFS increases the risk of
distortion. This is especially true if the levels
coming into the processor happen to increase
even further on other program material later on.
Operating with levels that are lower than
normal can run into different issues, par-
ticularly with the behavior of the AGC and
Compressor sections of processing.
Left/Right Channel Balance
This control is provided to trim the Left/Right channel balance by up to +/-12dB
should it be necessary.
High Pass Filter
A High Pass Filter is used to reduce or remove infrasonic (very low frequency)
signals from the audio that are not a part of the audio. Undesirable hum and rumble

page 2 - 5
Aura8ip / Jan 2012
Aura8ip GURU GUI
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 dene 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 nd 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 modied using the Guru
GUI’s six tweaker controls and then saved as new
presets if desired.

page 2 - 6
Aura8ip / Jan 2012
Aura8ip GURU GUI
We attempt to name presets according to the application that we feel they may be
appropriate for; however the name doesn’t always mean that the preset is only good
for an application by that name. That said, we do use a preset naming convention
that has four dened variables which are intended to make it easier for users to select
which preset to use or start with. That naming convention is as follows:
<Potential Use>_<Number of Bands>_<Tonal Quality>_<Dynamics Feel>
Following this, a preset called TalentHeadphones_3Band_Warm_Compressed
could be used for processing console audio for feeding it to talent headphones in
order to provide air staff a simulated off-air signal in the situation where the use of
diversity delay in an HD-equipped system makes listening to the actual off air signal
impractical.
Please feel free to experiment with each preset to see how it sounds in your appli-
cation. New presets are frequently added to the Wheatstone website for customers to
download, and presets can easily be installed into any Aura8ip via the GUI’s built-in
Preset Management feature.
Guru’s Six Adjust Sound Controls
The six controls in the Guru GUI
make adjusting the sound of process-
ing far easier than using the more than
90 controls assigned to Aura8ip’s pro-
cessing.
The Guru GUI has six “tweak-
ers;” four slider controls for adjusting
processing texture and two knobs for
adjusting the low and high frequency
equalization. When a Factory preset is
recalled all six tweakers reset to their
midpoint positions, which is “5” for
the four texture tweakers and “0” for
the two EQ tweakers. Each tweaker
then allows adjustments up and down from the Factory preset’s starting point. The
six Guru GUI tweakers are:
AGC Drive
This control adjusts how much long-term AGC processing is applied to the audio.
Higher settings cause deeper AGC action which will tend to hold up fading musical
passages longer while lower settings do the opposite.
Compression
This control adjusts the amount of medium-term compression. Higher settings
bring out subtle details in the program content as well as add a bit of energy and some
loudness to the signal. Lower settings do just the opposite.
