Networked audio system design with CobraNet™
This white paper’s subject is Networked audio system design with CobraNet™.
The design concept in this paper supports systems varying from small touring
event setups to very large scale networked audio installations. That does not
mean that the design concept is the best solution to all system specifications, other
network topologies and audio protocols should always be considered in the initial
phase of the design project. The advantage of this Yamaha System Solutions design
concept is that it is based on Ethernet / CobraNet™, both open protocols that use
computer networking components widely available on the market. Other compatible brands of both network and audio equipment can be included in the design
concept, assuring maximum flexibility and project efficiency for system integrators.
It is also good to know that the design concept is not just a theoretical exercise; we
have built, tested and installed systems based on this design concept so you can be
confident that the concept will work in real life.
We assume the reader is a system integrator with detailed knowledge of analogue
and digital audio, and basic knowledge of networking technologies as covered in
the ‘Yamaha System Solutions - an introduction to networked audio’ white paper.

1. System design
Customer’s requirements
Design options
Design tools
The first step in any design is to chart the customer’s
requirements. Sometimes the requirements can be found in
a formal tender if a consultant has already been involved
in the customer’s system specification process. In many
cases the consultant or system integrator has to discuss
the customer’s requirements in depth to find the most
appropriate system specifications, and perhaps suggest
additional system possibilities made possible by new
technologies on the market.
Based on the system specifications document, basic design
options can be conceived. The main decision to make is
the selection of the technology to be used: analogue or
digital, point to point or networked, closed (proprietary)
or open (manufacturer-independent) platforms etc. These
decisions are fundamental as they determine the degree of
freedom allowed in further design stages.
The more complex a system the more important design
tools become. A small system can be described in words or
an excel sheet, but larger or more complex systems have to
be described in drawings to be able to communicate them
to all stakeholders in a project. In these cases software
programs are used to construct system designs, such as
AutoCAD in the contracting business, StarDraw in the
audio markets and CobraCAD for CobraNet™ system
designs.
System specifications
After the technology platforms have been selected the
system’s actual network and audio devices must be
selected. Input parameters for selection include feature
set, audio quality, technical reliability, supplier reliability,
complexity and of course cost level. There are no products
with an ‘A-score’ on all of these parameters; quality comes
with higher costs, more functionality comes with a more
complex user interface, etc. The designer must study each
system component’s feature set in depth to assess if it meets
the system specifications or not, and conceive creative
solutions in case no matching products are available.
The second step is to draw up a system specification based
on the customer’s requirements. A system specification
document contains the requirements for a system to fulfill
as operational parameters. The system specifications
should not include any direction to actual solutions as that
would narrow the scope of possibilities in the design stage.
Only by keeping the system specifications and the design
solution options strictly separated can the broad scope of
choices be truly considered by the designer, allowing for
maximum flexibility, quality and creativity in the design
stage.
Selection of network and audio devices
System test
A very important part of the network design process
is to conduct (sub) system tests. Especially network
systems using managed switches offer an extremely high
functionality level that require system tests to verify that
all parameters have been programmed correctly.
Training & after sales
A networked audio system offers different functionality
compared to analogue systems. Therefore the design of
appropriate after sales and training activities for future
users of the system is an important part of the design
stage.
2. Specification list for Yamaha System Solutions CobraNet™ designs
Based on the customer’s requirements a system
specification must be drawn up. For this white paper a
‘one size fits all’ system specification is listed intended
to cover most of ‘every day’ applications from small
touring sound reinforcement sets to large scale distributed
i/o installations. Although this system specification list
will most probably produce a system design that meets
the average customer’s requirements, it might cover
more than required. To achieve efficient system designs
it is recommended to carefully go through the first step
of the system design process of charting the customer’s
requirements before drawing up the system specification
list.
True Network
The design concept should cover virtually all application
sizes; from simple P2P connections to large scale
installations with many locations. To allow this level
of scalability, and to keep systems manageable, a true
network protocol should be used. Functional connections
must be separate from the physical cabling in the network

application.

systems.
Status monitoring and control
Topology
For all designs, the network topology should offer easy
connectivity - supporting the use of cost effective computer
networking hardware.
Redundancy
The design concept should include a computer to control
and monitor the system’s audio and network devices.
Serial connectivity
Connectivity of serial standards such as RS232C and
RS422 should be possible using inexpensive hardware.
All designs should feature full redundancy for all network Ethernet connectivity
components. A system should recover automatically from
any network component failure.

connected to the primary switch, and the secondary links
to the secondary switch. In the star location’s secondary

4. Control network
VLAN
To ensure that CobraNet™ data traffic and other Ethernet
traffic flowing through the network can not interfere with
each other, a separate ‘control’ VLAN is used for all nonCobraNet™ devices. At each switch location two ports are
configured to carry the control VLAN signals.
M7CL Studio Manager
The control VLAN can be used to connect M7CL Studio
Manager to all M7CL consoles in the system. This way the
system engineer can plug in the Ethernet port of a laptop
anywhere in the system and have control over any console.
The Studio Manager software and the consoles are linked
together by their IP addresses.

Ports 1 and 2 are allocated to VLAN1: default (the control
VLAN). Ports 3 to 8 are allocated to VLAN2: CobraNet.
For locations with Fiber connectivity, one CAT5E patch
cable connects the TX Gigabit ports of both switches to
support the RSTP redundancy, while the GBIC slot is
used for connection with the star location. For locations
with CAT5E connectivity the GBIC slot is used for the
RSTP redundancy link, and the TX Gigabit port for the
connection with the star location.
For touring applications, two connectors are available on
the front panels: two EtherCon® connectors for redundant
CAT5E cabling or two Fiberfox® EBC52 connectors for
redundant fiber cabling. An end location can connect to
further CobraNet™ devices, other than those built in the
stage rack, using two EtherCon® connectors per device.
Redundancy
All connections come in pairs for redundancy. Connections
should be rolled out physically separated from each other
as much as possible to offer maximum protection from
cabling accidents e.g. involving rodents or heavy military
equipment.

6. Programming the network
Network settings
Switch IP address
VLAN and STP settings
Network settings have to be programmed using the
software provided by the switch manufacturer. Switches
can be programmed with a computer connected to one of
its network ports using a web browser such as Microsoft®
Internet Explorer in a user-friendly way. Old style
‘command line’ programming is possible using a serial
RS232C connection using the Windows® Hyperterminal
software; the Command Line Interface (CLI) that has to be
used will be described in the switch’s users manual.
The switch’s web based user interface can be accessed
using Microsoft® Internet Explorer. Out of the box,
every switch in this example will have the same default
IP address, so the first thing to do is to connect each
switch one by one as a single device to a computer using
an Ethernet crossover cable. Then log in using the default
IP address specified in the switch’s users manual, leaving
the user name and password empty. To be able to access
the switches after they are connected in the network, it’s
best to change the IP addresses of all switches to a logical
order range on the control network that you will use for IP
services in the system, and document the addresses in the
system project document. After setting the new IP address
and subnet mask store the settings and then log into the
web based user interface again using the new IP address.
Connect to the switch using a port planned to be in the
Default VLAN.
For Dlink switches the VLAN settings are available under
the ‘L2 features’ tab in the folder hierarchy on the left side
of the web display. Clicking the ‘Static VLAN entry’ tab produces a list of programmed VLANs. Use the ‘modify’
or ‘add’ buttons to set up the VLANs. To set the spanning
tree parameters access ‘Spanning Tree’ under the ‘L2
features’ tab. Don’t forget to store all settings after every
change !
Port-based VLAN’s have to be programmed one by one on
all switches. On the secondary star switch RSTP should be
enabled on the ports connected to the other switches in the
system. RSTP should be disabled on all other ports and all
other switches in the system. Connect the secondary star
switch to the network only after RSTP has been enabled.
In the end locations the switches’ default VLAN should
include ports 1 and 2, an additional CobraNet™ VLAN
should include ports 3 to 8. Both VLANs should be
tagged and assigned to ports 9 and 10. On the secondary
star switch RSTP should be enabled on the long distance
link ports only. Then test the system and fine-tune STP
settings.

8. Yamaha CobraNet™ devices
NHB32-C
DME Satellite
MY16-CII
The NHB32-C is a 32 channel AES/EBU network hub and
interface to CobraNet™. The back panel offers four 25-pin
Dsub connectors for 8 channels / 4 pairs AES/EBU inputs
and outputs each. In 5.3 ms and 2.6 ms latency mode the
NHB32-C supports 4 CobraNet™ bundles in and out, with
a programmable matrix router between the AES/EBU i/o
and CobraNet™ bundles. In 1.3 ms latency mode there is
a restriction of using four bundles in total for inputs and
outputs.
The DME Satellite series are compact 1U units with 8
channels of analogue i/o, 8 GPI inputs and 4 GPI outputs. The DME satellite is available in three analogue i/o
configurations: 4 in 4 out, 8 in or 8 out. All analogue inputs
offer a remote controllable head amp for easy connectivity
of microphone level signals. A serial port is available for
remote control of AD8HR units or RS232C control by
AMX™ or Crestron® systems (for example).
The MY16-CII is the successor of the MY16-C with
connectivity to all MY16 compatible products. The power
supply limitation is solved so the card can be used in any
MY16 compatible digital mixing console. The setting of
bundle numbers with rotary switches has been replaced
by software control using the supplied CobraNet Manager
Lite software package.
MY16-C
ACU16-C
The ACU16-C offers sixteen analogue 24-bit 48 kHz
outputs on Euroblock connectors to drive power amps. An
RS485 data connector is included to connect to a series of
PC01N power amplifiers, bridging the connection to other
ACU16-C units in the network. This functionality allows
control, logging and monitoring of all PC01N amplifiers
with a PC connected to the USB port of any ACU16-C or
NHB32-C in the CobraNet™ network.
NHB32-C
The MY16-C offers 2 bundle i.e. 16ch in & 16ch out
CobraNet™ connectivity to compatible MY16 devices
such as the M7CL, DME24N, DME64N, PM5D. Due to
power supply limitations, the use of the MY16-C in the
DM2000 is limited to one card only, and the MY16-C can
not be used in other MY16 compatible products such as
the DM1000, 02R96, 01V96.
DME4io-C
DME24N, DME64N
Both DME24N and DME64N can connect to a CobraNet™
network using MY16-C or MY16-CII cards.
Digital mixing consoles
Any Yamaha MY16 compatible digital mixing console
can connect to a CobraNet™ network using the MY16-CII
card. The PM5D and M7CL also accept MY16-C cards.

Checklist
Check 3: Double check audio settings
Check 6: Sabotage
After assembling a networked audio system it is good
practice to conduct a systematic series of checks to make
sure everything is OK. These checks should include
network functionality, audio functionality and sabotage
behavior.
Using the appropriate software, double check the audio
settings in all individual CobraNet™ devices: bundle
numbers, wordclock settings, sample size and latency
mode. Confirm that the conductor is assigned to the
appropriate device.
Check 1: Double check network settings
Check 4: Listen
Sabotage all network components in the system one by
one: remove cables or power down switches, confirm
system recovery, re-connect or power-up, confirm that
the system switches back to a redundant state. Note the
recovery timing at each stage to include in the project
documentation.
Troubleshooting
Connect a PC to the default VLAN and confirm that
all switches are on-line, for example Dlink’s D-View
monitoring software. Double check the VLAN settings
and STP settings in every individual switch by browsing
them one by one.

M7CL FOH & monitor locations, stage amplifier rack, two 24ch input racks
System
CobraNet™
IP over Ethernet
As the system star location includes high capacity switches
with fans it is located in the amp rack - set up in a place
where the amp’s fan noise is not a problem. One mixing
console is located on the FOH position, one on the Monitor
position side stage. Two 24 channel input racks are set on
stage, with 8 returns each for local monitoring. Double
(redundant) EtherCon® cabling is used for the long
distance links.
Each stage rack transmits three multicast bundles to be
picked up anywhere on the network. From FOH and MON
mixers unicast bundles are sent to the amplifier rack and
the two stagerack return outputs. A third mixer, recording
rack or a clean feed to an OB van can be added to the
system at any time at any location.
The control network is used to connect the RS422 head
amp control signals from the FOH M7CL mixer to the
first stage rack, and from the first stagerack to the second
using serial servers. A laptop is connected to the FOH
location (or any other location), allowing access to both
FOH and monitor mixers, the DME output devices in both
stageracks and the IP cameras in the amplifier rack, FOH
mixer and Monitor mixer locations.

4-location boardroom with analogue I/O and control
System
CobraNet™
IP over Ethernet
All four rooms offer connectivity to four analogue stereo
player/recorder devices such as compact cassette, CD,
DVD, Minidisk etc. Two faders and on/off switches with
tally LED are provided in all four rooms for simple control
of the audio level. Further GPI inputs and outputs are
available to control external equipment. More detailed
control of the audio functionality can be realized using a
computer with DME designer user control displays on a
computer display. Crestron® or AMX™ Control systems
can also be used, integrating other multimedia devices in
the system such as video recorders, projectors etc.
Each room features one DME8i-C and one DME8o-C
device offering 8 inputs and 8 outputs in all rooms. Each
DME8i-C unit transmits one multicast bundle so all inputs
of all rooms are available in any location. For ad-hoc
expansion a mixing console or extra i/o devices can be
connected to any switch in the system, e.g. when two or
more rooms are combined for a company presentation an
01V96 mixing console can be used to mix the event.
A computer can be used to control the DME units in the
system with user friendly control menus on the computer’s
display. GPI functionality of each DME device in the
system can be linked to all other DME devices for detailed
control of the complete system functionality. Each room is
fitted with an IP camera offering simple and cost effective
video links between rooms using computers connected to
the control network. As the DME designer software offers
easy interfacing functions for Crestron® and AMX™
systems, the audio system can be integrated in total
multimedia systems based on these platforms.

White paper ‘networked audio system design with CobraNet™’
Yamaha’s expanded Commercial Audio portfolio facilitates a single
manufacturer solution to the most complex of audio installation and
touring challenges. We offer digital mixing and processing as well as
multi-channel, networking amplification and a wide range of advanced
output devices.
Although we are proud of our line up of excellent quality products, we
understand that a system solution includes more than just products:
cabling, network technology, design tools, quality management tools
etc. This document aims to support networked audio system design
including examples of 3rd party components.
