Introduction
SymNet™ is a scalable DSP platform configured by SymNet
Designer software and made by Symetrix. Installed in
Convention Centers, Sports Arenas, Houses of Worship
and many other venues throughout the world, consultants,
integrators and end-users rely on the robust stability of the
SymNet platform.
SymNet is an open architecture system. This means DSP
modules (EQ, compression, etc.) are placed into the
design and connected using standard drag-and-drop
methods. Various SymNet hardware can be chained
together to provide a custom audio solution for the client.
SymNet’s main advantage can be summed up in one word:
“Options”. Options for DSP processing, options for audio
routing and options for control.
Note: Express Cobra devices require SymNet Designer 5.0
or later.
Overview
SymNet Express Cobraisafamilyof19”rack-mountable
digital signal processors (DSP) that are setup and controlled
by SymNet Designer software. Ideal for audio applications
such as churches, conference rooms, courtrooms, night
clubs and many others. ARC Wall panels easily integrate
with Express hardware and provide simple user control of
the system.
There are four analog I/O options available for the
Express line: 12x4, 4x12, 8x8, and 4x4. Express devices
employ industry-standard CobraNet®technology to share
audio between devices supporting 16 inputs and 16 outputs
of CobraNet audio over Ethernet in addition to the analog
I/O.
Devices are initially configured through the RS-232 port on
the rear panel. This same port is used to connect to external
controlsystemsfromAMX,Crestron,andothers.Once
the system is initially configured, Express devices can be
addressed and controlled over Ethernet.
Any of the ARC Wall Panels can be connected via CAT5
cable to an RJ-45 jack on the rear panel. One channel of
analog audio can be routed to or from the wall panel over
the CAT5 cable for simple paging or monitoring needs.
ExpressalsoincludesanRS-485portforextendingtheARC
and external control capacity.

Host Communications
The host PC (running SymNet Designer) can communicate directly
with the Express as a stand alone device (Ring #1) in one of two ways:
RS-232 or Ethernet. Control over CobraNet may be available in a future
software release. For the time being, the CobraNet port is for CobraNet
Network Audio only and the Ethernet port is for host control only.
RS-232:
The Express has only one RS-232 port on the rear of the device, a
slight departure from the traditional SymNet DSP devices. As a result,
this rear panel RS-232 port sees double duty as both a host PC
interface or a 3rd party RS-232 accessory controller interface, but not
both simultaneously. The port’s purpose is set by DIP switch #2 labeled
“RS-232: Host / Acc”. When this switch is set to the “Host” position,
DIP switch#1labeled“HOST:115k/57k”determinesthebaudrate
oftheRS-232port(115.2or57.6kilobaud)andthisbaudratemust

Ethernet:
TheExpress’s10/100Base-TEthernetportisavailableforuse
regardless of DIP switch #2’s position. Ethernet or “IP” control is the
only way that multiple Express devices can be configured within the
same Site File. With an Express Cobra’s Ethernet and CobraNet ports,
these devices can be made part of a larger SymNet system which may
utilize1ormoreRingsoftraditionalSymNethardware(CobraLink,8x8

Note: Ethernet communications settings (IP addresses and access
codes) must first be set up from SymNet Designer via the RS-232
port interface. Please see the SymNet Designer online help for further
information.

Quick Start Guide
Multi-RingSystems•DeviceAddresing•RelayOut
Multi-Ring Systems
When using multiple Express devices or integrating Express
and traditional SymNet Rings, there are basically two ways
in which to set up multi-ring systems. The decision to make
is whether you would like to manage the rings as a whole
system from the same Site File or manage the rings as
completely independent systems (unique Site Files).
Interfacing to manage each ring as a separate system can
be done via RS-232 or Ethernet. If by Ethernet, care must
be taken to avoid IP conflicts and accessibility should be
considered - general network design and administration
issues. If by RS-232, separate PCs can be permanently
connected to each ring individually, or one PC could be
meant to ‘roam’ amongst them.
To manage the rings in one Site File as a whole system,
each hardware device must have its own dedicated Ethernet
connection to a common hub, switch, router or existing
network. Any properly set up PC on the network can then
control the system.
Device Addressing
Every Express hardware device contained within a common
Site File must be uniquely identified as its own ring. A Ring
address of 1 through 31 is available. If the Express device
is stand-alone (the only device in the Site File) it must be
Ring 1. The device addresses of the physical hardware
in your system must match the devices as configured in
your SymNet Designer Site File. You may use the pictorial
diagrams below to quickly set up and understand the device
address DIP switches on the Express.
Note: Any time the DIP switches are changed, the device(s)
must be power cycled for the changes to take effect.
Relay Out
The Express provides one (1) SPDT relay contact. Common,
Normally Closed and Normally Open pins are furnished on a
3-pin Euroblock connector. Contact ratings for the relay are:
3 Amp, 24 VDC, resistive; 0.3 Amp, 60 VDC, resistive. Do
not use at 120 VAC. (Please see the SymNet Designer online
help for information on how to address the Relay Output in a
SymNet DSP design.)
Note: This relay can also be used for power failure
detection. This option is set in the I/O Options of the device
Properties dialog. See SymNet Designer online help for more
information.

Binary (Open Collector) Outputs
The following illustrations depict three typical open collector
output hook ups. The most common uses for the open
collector outputs are to fire external LED indicators (LED
lit when O/C inactive) or drive external relays. (Please see
the SymNet Designer online help for information on how to
address an Open Collector output in a SymNet DSP design.)
Analog Control Inputs
The following illustrations show the connection of either a
10k Ohm linear potentiometer, a mechanical rotary encoder
or switches to one of the 2 analog control inputs of the
Express. (Please see the SymNet Designer online help for
information on how to assign an analog control input to a
SymNet DSP parameter. Note: The Express’s Control In
ports must be set to Pot, Switch or Encoder modes in the
I/O Options of the device Properties dialog. See SymNet
Designer online help for more information.)
The Symetrix model RC-3 is the perfect potentiometer
match for the Express. Suitable potentiometers, switches
and encoders might also be sourced from electronic parts
suppliers such as Digi-key. Note that encoders must be of
the mechanical type.

more ARCs arranged in one or more chains over standard
CAT5 cable. The Express Cobra can support up to two
(2) ARCs total within the guidelines set forth in the ARC
Network Design section. (Please see the SymNet Designer
online help for information on how to program the ARC.)
WARNING: The RJ-45 connectors labeled “ARC”
are only for use with the ARC series of remotes.
DO NOT plug the ARC connectors on Symetrix
products into any RJ-45 connector labeled
“SYMLINK”,“ETHERNET”or“COBRANET.The“ARC”RJ-
45 connectors on Symetrix products can carry anywhere
from 6 to 24 VDC which can damage SymLink, Ethernet and
CobraNet circuitry.
ARC Network Design
The ARC can be powered two ways: (1) over CAT5 via the RJ-45
“ARC” port on ARC-enabled Symetrix products, or (2) by local 6 to 24
VDC power supplied to the ARC’s terminal block connections.
The ARC’s power requirements vary depending on the
voltage supplied to it. At 15 VDC, it uses approximately
115 mA, while at 6 VDC it uses approximately 300 mA
maximum. As the voltage goes from 15 to 6 VDC, the
current requirement increases accordingly.
ARCs can be daisy-chained and fed power over this daisy-
chain from the ARC port. However, as the length of the
cable increases, so does the resistive line loss, which lowers
the voltage available at each subsequent ARC. The actual
power drain on each output from an ARC port can vary
substantially depending on the number of ARCs and the
distance each of them is separated by. In order to assist
withsystemdesign,SymetrixhasavailableaMicrosoftExcel

power requirements based upon cable length, number of
ARCs and the power supply to be used. This spreadsheet

WAR
NING: When designing a system, one must be
careful not to double power any ARCs. If all pins on
the CAT5 connections are used, power can travel
over the CAT5 cable and reach any ARC on
that particular chain. So, power over CAT5 could potentially
come from the originating ARC port or from an ARC that is
powered locally and then daisy chained via CAT5 to other
ARCs. In general, it is recommended to use only one type of
connector on the ARCs, either the RJ-45s (with CAT5 cable)
or the terminal blocks

ARC Audio
ARC Audio provides a means to take a single balanced
analog audio line and either inject it into or pick it off an
RS-485network’sCAT5cablerun.AnARCAudioportona
Symetrix device may be wired to a nearby device’s analog
input or output. This provides a means of easily running a
single audio channel to or from a remote source or destination.
TheARC-MICandARC-XLRmakeuseofARCAudioto
transport audio signals back to a SymNet rack mount unit.
Note 1:TheoriginalMenuARCremote(simplynamed
“ARC”) does not support ARC Audio lines and will ground
the audio lines if connected.
Note 2: To avoid the possible grounding, mixing, or shorting
of the ARC Audio lines, it is recommended to home run any
ARC devices making use of the ARC Audio lines so that only
one ARC device is on each chain.
Limits of ARC Audio
ARC Audio is a simple analog audio signal travelling the
samecableastheRS-485dataandpower.Assuch,the
usual audio signal cautions apply. Avoid running parallel to
otherpowerlinesornearanyothersourcesofEMIorRFI.
MostCAT5isunshieldedandissusceptibletointerference
and noise. We provide here the following information on ARC
Audio’s performance and limitations:
Line-level Balanced Audio:
Professional line level balanced signals can also be sent over
up to approximately 1500 feet of CAT5 without significant
degradation.
All unbalanced signals should be avoided completely.
Mic-level Audio:
Unbuffered condenser or dynamic microphones should
generally be avoided, though it may be possible to achieve
decent quality with cable runs of less than 50 feet using a
fairly hot microphone level with a noise gate or expander
in to clean up the signal. This technique does not provide
much flexibility within the system design, and therefore is not
recommended.
Frequency response:
Frequency response can roll-off due to the capacitance of
a long cable run. The amount of roll-off is highly dependent
on source impedance (the output impedance of what is
supplyingthesignal).Mostproaudiodeviceshavelow
output impedances (200 Ohms or less) and do not suffer
signicantroll-off(approximately-1dBat20kHzwith1500
feet of CAT5). A device with a 600 Ohm output impedance
couldcausesomeaudibleroll-off(-3dBat10kHz),but
should be of sufficient quality for speech signals.
Data Noise:
With an unbuffered mic and long cables, data noise may
be audible as a “motorboat” sound. Experimenting with
RS-485terminationandbaudratemayimprovethesound
somewhat.

CobraNet
Developed by Cirrus Logic, CobraNet™ is the industry’s
leading technology for distributing uncompressed real-time
digital audio over a Fast Ethernet network. It is the standard
technology for the transport of multi-channel audio and
controldata.CobraNetusesaFastEthernet(100Base-T)
network. The CobraNet implementation in allows for 32
transmit channels and 32 receive channels.
Note:Bundlesareameansofgroupingchannels.Bundles
may be multicast (one to many) or unicast (one to one). Only
one device may transmit on a particular bundle.
The limitations of Fast Ethernet also apply to CobraNet. This
means that when using standard copper CAT5 cabling, the
total network diameter is limited to 200 meters (100 meters
between devices (nodes) and their common hub; switch,
router, etc.).
If greater distance between devices is necessary, you can
convert to fiber using media converters or network hardware
with fiber bridging/conversion built-in. In all cases, the
networking hardware used for CobraNet should be on Cirrus
Logic’s recommended hardware list. For further information
on designing CobraNet networks, or to obtain a list of
recommended network hardware, see Cirrus Logic’s web
site: http://www.cobranet.info.
CobraNet Examples
The following diagrams depict some typical CobraNet
networks and what can be accomplished with each
particular network.
Serial control of a CobraNet network:
Two or more CobraNet devices on a common private
CobraNet audio network controlled from a PC via a
serial (RS-232) connection. The PC may connect to any
CobraNet-networked Express or CobraLink. This most basic
setup allows the sharing of audio and control data between
CobraNet devices while minimizing setup, security and
network traffic issues.
Integrating Express Cobra with existing or
additional SymNet devices via CobraLink:
Express Cobra can share audio and control data with a
traditional SymNet ring if that ring contains a CobraLink
device. CobraLink has only one RJ-45 connector which
carries both CobraNet and data traffic. Therefore, it is
necessary to combine the dedicated Ethernet and CobraNet
RJ-45 connectors on an Express Cobra using a hub,
switch or router. Remember to use Cirrus Logic approved
networking hardware.
Note: “SWITCH” is used as a
generic label for any Switch,
Router, etc.

SymNet Express Cobra Family 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.

you are connecting to an older SymNet system, the firmware versions
in hardware must match those included with the version of SymNet
Designer you are using. The correct firmware files are always included
with each software release.
When downloading a Site File to SymNet hardware, the firmware
versions will be checked and you will be prompted to upgrade firmware
if necessary.
CobraLink and Express Only: For CobraLink and Express Cobra
units, there is also CobraNet firmware from Cirrus Logic. You may need
