Voice Processor 2x Wiring Reference
Unbalanced Connections:
Unbalanced out to balanced in
The RCA connector and the 1/4” TS connector are
unbalanced connectors. However, the wiring differs
depending on if they are sending to, or receiving from a
balanced connector.
In this example, the unbalanced connector is sending signal
to a balanced connector. When wiring this connection,
use a shielded twisted pair cable. The balanced side wires
the same as a standard, balanced connection. On the
unbalanced side, you wire the white (minus) wire together
with the ground. This provides some common mode rejection
at the balanced input.
Unbalanced Connections:
Balanced out to unbalanced in
When your output requires a balanced connector, but you
are sending signal to an unbalanced input, the rules change.
Use a single strand shielded wire. Wire only to the plus and
ground terminals of what would the typically be the balanced
connector.

Quick Start Guide
2xNetworking
Network Configuration
The 2x is setup and controlled by a host computer via
Ethernet. This requires the host computer to be connected
to the 2x directly via a standard CAT5 Ethernet cable,
indirectly via an Ethernet switch, or via an existing Ethernet
network.
The primary difference between the three methods of
connection is that in the first two, the 2x software application
assumes there is no DHCP server or other network
infrastructure in place. It assumes the 2x is using a self-
generated IP address and adjusts its connection steps
appropriately. In the third method, it is assumed that a
DHCP server and/or router with DHCP server are already
present on the existing network so the 2x may already have
obtained an IP address. Consult your network administrator
if in doubt.
General Notes
1. The 2x boots up with DHCP enabled by default. This
means that as soon as you connect it to a network, it will
look for a DHCP server in order to obtain an IP address.
If a DHCP server is present, the 2x will get its IP address
from it. This process may take several minutes. With your
PC attached to the same network and thus getting its IP
address from the same DHCP server, all will be ready to
go.
2. If your network does not have a DHCP server, the 2x
will not be able to obtain an IP address. While waiting,
the 2x will default to a private IP address in the range
of169.254.x.xwherex.xisthelastfouralphanumeric
charactersofthe2x’sMACaddress(MACaddresshex
value is converted to decimal for IP address). The 2x’s
MACaddresscanbefoundonastickeronthebottom
of the 2x or within the front panel System menu. When
there is no DHCP server present to assign IP addresses
to either the 2x or your PC, you may need to configure
yourPCwithastaticIPintherangeof169.254.x.xwith
aSubnetMaskof255.255.0.0inordertocommunicate
with the 2x in a direct connect mode. However, if your PC
is using the default network settings, it should also have
automatically self-assigned a similar private IP address
intherangeof169.254.x.x,andifthisisthecase,you
should be able to connect to the 2x directly. Even if the
PC’s default settings have been changed, the 2x will try
to establish communications by setting up appropriate
routingtableentriestoreachdeviceswith169.254.x.x
addresses.
3. In the case of the first two methods (direct connection
and indirect connection), the 2x software will attempt to
set-up appropriate routing table entries for a seamless
connection regardless of the IP addresses of your PC
and 2x. However, under Windows® Vista, administrative
privileges are required to allow the 2x software to modify
the routing table. For best results, launch the 2x software
while logged in as an administrator, or choose to run the
software as an administrator. Note: To run a program as
the Administrator under Vista, right click on the program’s
icon or shortcut and choose “Run as administrator”.
4. The 2x will display its current IP address, subnet
mask, and gateway as well as other useful information
onthefrontpaneldisplaywheninSystemMode.To
enterSystemMode,holddowntheMenubuttonfor5

to move between various displays. This information may
be useful for troubleshooting.
Network configuration of the 2x:
Connecting to the 2x from a host computer on the

1. IP Address - The unique address of a node on a network.
2.SubnetMask-CongurationthatdeneswhichIP
Addresses are included in a particular subnet.
3. Default Gateway (optional) - The IP address of a device
that routes traffic from one subnet to another. (This is only
needed when the PC and 2x are on different subnets).
If you are putting the 2x on an existing network, a network
administrator will be able to provide the above information or
it may have been provided automatically by a DHCP server.
For security reasons, it is not recommended to put the 2x
directly on the Internet. If you do, a network administrator
or your Internet Service Provider can provide the above
information.

If you are on your own private network, directly or indirectly
connected to the 2x, you may allow the 2x to choose an
automatic IP address or you may choose to assign it a static

with static assigned addresses, you may consider using an
