I/O Connections
All audio input and output, control, Ethernet, and power supply
connections are made via various connectors mounted on HD P3’s rear
panel. Seven XLR connectors are provided for analog and digital audio
input and output, and all the audio connections also appear on the DB-25
connector.AnRJ-45connectorisprovidedforEthernet connections. The
DB-9 connector provides 8 GPI inputs for the most used presets. The
pinout drawings on pages 1-8 and 1-9 summarize all wiring connections.
Inputs
BothHDP3processorsignalpathscanbefedfromtwodifferenttypes
of inputs: analog line level and AES-3 digital.
Two female XLR connectors, or the appropriate pins on the DB-25
AUDIO I/O connector, are available for line level analog audio input
(nominal +4dBu balanced) connections. The analog line inputs exhibit a
bridging impedance and can handle signals up to +20dBu.
A third female XLR connector is available to handle digital line level
sources;thisAES-3digitalinputisalsoavailableontheDB-25connector.
The HD P3 will accommodate digital inputs having sample rates of
44.1kHz or 48kHz. The internal sample rate of the HD P3 will automati-
cally sync up to the applied input signal’s valid sample rate, allowing the
HDP3tobeused in an existingdigitalsystem.AESsources are by design
stereo; if the HD P3 is not set to be stereo the appropriate Left or Right
signal within the AES stream will be applied to the signal path.

Digital Audio Connections
CABLE - All AES/EBU input and output digital audio connections are
balanced and should be made using a high quality digital audio cable. Be
sure to select a digital audio cable with an integral drain wire of the same
wire gauge (AWG) as the twisted pair as this facilitates an easier consistent
termination process. Typical AES/EBU digital audio cable has a very low
characteristic capacitance per ft (pF/ft), and a nominal impedance of
110Ω. High quality digital audio cable offers better signal transmission
performance versus typical analog audio cable, especially over long cable
runs. Check the cable manufacturer’s data sheet to be sure the cable you
plan to use will work in your application.
CONNECTORS - The AES/EBU connections are made with the
supplied DB-25 male mating connector, or with XLR connectors. The
DB-25 crimp style connector will accept wire gauge 22 - 28AWG. Please
refer to the XLR mating connector manufacturer's recommendations for
termination instructions.
Unbalanced Analog Connections
ANALOG INPUTS — Wire to the processor input end with typical
shielded, two conductor cable (like Belden 9451), just as if you were
connecting a balanced source. At the unbalanced source machine’s output,
connect the + output to the HI input wire and connect the source machine
GND wire to LO. Connect the shield at the HD P3 end only.
Note: Unbalanced analog sources typically have -10dBv (316mV RMS)
signal levels and will not match the processor nominal operating level of
+4dBu (1.23V RMS). We highly recommended that you first externally
balance any unbalanced sources you plan on connecting to the Vorsis HD
P3. Many third party “match boxes” are commercially available for this.
ANALOG OUTPUTS — The HD P3 analog outputs use a balanced
output circuit which behaves exactly like the secondary of a high-quality
transformer, with no center tap—this output is both balanced and floating.

HD P3 / Aug 2006
For unbalanced operation, either the HI or LO side of the analog output
must be strapped to ground of the unbalanced input, with the output taken
from the other side. (Normally you would strap LO to ground, and use HI
to feed your unbalanced equipment input.) Leave the SH floating at one
end.
Unbalanced Digital Connections (SPDIF)
SPDIF INPUTS — The SPDIF (Sony/Phillips Digital Interface) or
“consumer” digital audio interface is a two wire unbalanced signal
typically on a single RCA style connector. Note that the SPDIF signal level
of approximately 500mV and 75 ohm impedance does not correctly match
the processor’s AES-3 input. We highly recommend using a “balun” or
format converter when interfacing “consumer” grade source devices to the
processor.
In cases where a consumer grade device must be interfaced and the
appropriate matching device is not available, try wiring the SPDIF center
conductor (HOT) to the HI input pin and SPDIF shell (ground) to the LO
input. Connect SH at the processor end only.
SPDIF OUTPUTS — The Vorsis HD P3 digital outputs are fixed,
professional, AES-3 formatted outputs. SPDIF consumer format is not
supported. Use an external format converter to connect the digital outputs
to consumer gear.

withtheunit.ItisaWindows™GraphicalUserInterface(GUI)program,
intended to be straightforward in use, controlling and displaying the
powerful features of the HD P3 to best effect. It is supplied as a self-
installing program which may be executed from any directory on the
computer, the resulting files being installed under “Program
Files\Vorsis\HDP3”.TheprogrammaybestartedfromtheWindowsStart
menu. A registration key is required from Vorsis to operate the program
longer than a week.
NOTE: A basic familiarity with Windows navigation techniques is
assumed. If terms such as “left-click”, “right-click”, “double-click”, and
“drag-and-drop”seemalien,operatingtheHDP3GUIcouldbeproblem-
atic.
Connecting the HD P3 and the GUI
The HD P3 and PC running the HD P3’s GUI program can be
straightforwardlyconnectedtogetheroverastandardEthernetLocalArea
Network (LAN).
The HD P3 should be installed, powered-up, and verified to be
operatingnormally;aCAT5cableconnectedtothe100baseTLANshould
be inserted into the appropriate socket on the rear. Likewise, the GUI
should be installed on the desired PC which is verified to be working
correctly with the LAN.
ItisalsopossibletoworkwithoutaLANbyconnectingtheHDP3and
the PC Ethernet ports together using a crossover cable.
Constraints for the system are not extraordinary, in that that the PC
shouldbe preferably atleast 1GHzin speed, andthat thescreen be atleast
1024 x 768 pixels in size. The LAN should be 100baseT (100MHz)
capable.Itisindeed possiblefortheGUI to berunon a portablecomputer
connected to the LAN by wireless (802.11b as a minimum) as long as the
HD P3 itself “sees” a 100baseT network. The dodgier the radio link,

IPAddress Configuration
TheHDP3requiresaManuallyConfiguredIPaddresstype.Automatically
assignednetworkaddressingusingDynamicHostControlProtocol(DHCP)is
not supported. Your HD P3 was assigned the following default parameters at
the factory:
IP address: 192.168.1.191
Subnet Mask: 255.255.255.0
Gateway: 255.255.255.255
ThedefaultIPaddress,subnetmask,andgatewaymaybechangedusingthe
HD P3 GUI’s Hardware>Assign IP Addresses... menu item. Right-click
anywhere to open this menu. Note that your PC’s IP address does not need to
be on the default HD P3 192.168.1.xxx subnet in order to change the HD P3’s
defaultIPaddress,butyoudohavetobeonthesamesubnetinordertoactually

Once connected and Online, the meters will be moving on the HD P3. Try an
analog source, then digital source if analog does not get the HD P3’s meters
going. You can also “ping” the HD P3 from the Windows
Command Prompt.
Creating a New Device
This step creates a virtual device and points the GUI to it.
• Right click anywhere on the GUI and select Hardware
>Devices... fromthepop-upmenu-theDevicesdialogbox
opens.
• Press the Addbutton and enter an 8 character Name and the
desired IP Address.
• Click OK when completed.
• Click on the newly created Device name and press the
Select button. The Devices dialog box closes and the
newly created Device name will appear in the Devices
window at the top of the Vorsis HD P3 GUI.
• Click the Online button at the top of the control pane,
when enabled a green LED is “lit” on the button, the
Status window will display Trying...
You’ve created the Device and pointed the GUI to it,
now let’s change the HD P3’s IP address.
TIP: Right-clickany-
where on the HDP3
GUI window to bring
up the menu.

Changing the HD P3 IP Address
This step changes the IP address of the HD P3’s NIC. Note that your
PC’s IP address does not need to be on the default HD P3 192.168.1.xxx
subnet.
• Right-click anywhere on the GUI and select Hardware > Assign IP
Addresses... An IP Assignment dialog box opens.
• Enter the MAC address from the HD P3’s label
(affixed to top cover).
• Enter a new Name, IP Address, Subnet Mask, and
Gateway.
• Press Start - you will be asked to re-boot the HD P3
(power down, then up).
In a few seconds after you cycle power you will see
the Requests counter begin to increment, usually, up to
2. In a few more seconds you should see the Status
window change from Trying... to Online. The audio
meterswillalsobeginmovingifyouhaveaudioplaying
and are actually Online.
You may now Close the IP Assignment dialog box.
That’s it!
Troubleshooting IP Addressing Problems
•Once youhave changedthe default HD P3 IP address,
be sure your PC’s NIC is on the same subnet as your
new HD P3 IP address.
• Be sure the Device is defined correctly in the Hard-
ware >Devices... menu.
• Be sure you have Selected the desired Device in the Hardware >De-
vices... menu.
• Check that the Ethernet cables are plugged in and LINK led’s are lit.
• Use a crossover cable if connecting the PC directly to the HD P3. Try
using Windows XP Repair connection to reset the PC’s NIC.
• Check that the HD P3 is powered ON.
• If Online but no audio, check that the Input source is correct, Analog or
AES.
If for some reason the device does not connect and go Online, try
following the instructions for Creating a New Device and Changing the
HD P3 IP Address again.
