INSTALLATION
Connecting your EtherSound rack
It is recommended to establish all connections before powering the device up.
Power supply
Before plugging the power cord, make sure that:
• The cord it is not damaged
• the AC outlet used is properly earthed
Just like for any other audio system, power the individual devices up following the audio path and power
down in the opposite direction.
Do not allow anything to rest on the power cable. Keep the power cable away from where people could trip
over it.
Network
The cable type most commonly used today is CAT5e. For more detailed information, please refer to the
document “Building ES Networks”, available on the Digigram web site.
The network connections are established via two Neutrik
TM
EtherCon
TM
RJ45
receptacles. Use the connector labeled “ES IN” to connect the descending
EtherSound stream (downstream, coming from the ‘Primary Master’), the
connector labeled “ES OUT” to connect the ascending EtherSound stream
(‘upstream’).
Use the RJ45 labeled “DATA/CONTROL” to connect your AQONDA to any
PC on the network running an EtherSound control and management software
such as EScontrol to remotely configure and manage your network.
The Neutrik
TM
EtherCon
TM
RJ45 provide secure connection through a latching system. To disconnect the cable
from the device, press the latch, then withdraw the cable while maintaining the latch pushed.
Example 1: bi-directional point-to-point transmission of eight / sixteen audio channels
This application is very easy with two EtherSound AQONDA 8 or AQONDA 16.
Connect a standard Ethernet cable between the “OUT” port of the first Ethernet bridge to the “IN” port of the
second Ethernet bridge. Connections the inputs and the outputs of the two devices via the EtherSound
channels.
Example 2: more complex architectures
System topology may be daisy chain, star, or a combination of both.
Generally speaking, the “OUT” of an EtherSound device has to be connected with the “IN” port of the
following EtherSound device.
Repeat this step for each device in the network. Media converters (copper / fiber optic) can be used to
establish connections over very long distances. It is also possible to use Ethernet switches to build complex
topologies networks (see the document “Building EtherSound Networks” on our Web site).
Synchronization
AQONDA 8/AQONDA 16 provide several modes of synchronization.
Synchronization by means of:
• an internal oscillator (44.1 or 48 kHz)
• The network (except for “Primary Master” mode (see glossary))
Aqonda 8/16
Ethernet Audio Switches
11
• the Word clock input
If an AQONDA is “Primary Master”, it can be synchronized on its internal oscillator, or on the signal present
on the Word Clock input.
If the equipment is not in “Primary Master” mode, it can be synchronized on the clock provided by the
“Primary Master” through the network, or on the signal on its Word Clock input. In this last case, it has to be
made sure that the reference clock of the “Primary Master” and the Word Clock signal provided to the device
are synchronous.
These elements can be parameterized through the EScontrol configuration software, available on our web site.
Audio
The pinout used on the XLRs is standard: pin 1 carries the signal ground, pin 2 carries the positive signal
(“hot”, +) and pin 3 carries the negative signal (“cold”, -).
GPIOs
AQONDA 8 et AQONDA 16 are delivered with eight GPIs and eight GPOs on terminal block connectors; the
counterparts are provided. For details see Appendix A.
Serial port (RS232/422 on DB9)
AQONDA 8 and AQONDA 16 feature an RS232/422 serial port on male DB9 on the back panel. Use this port
to connect any compatible device. For the specifications of the serial port, please refer to appendix B of this
manual).
Note: The serial port is not operational yet.
Connecting a computer to configure the device and the manage an EtherSound
network
To connect a PC directly to an AQONDA, it must be equipped with a network card. Use an Ethernet cable to
connect the network card to the “DATA/CTRL” port of the AQONDA.
It is also possible to connect to the device through a conventional Ethernet network.
Two software applications allow for configuration of an AQONDA and control of an EtherSound network:
EScontrol, available on the Digigram web site, and ESmonitor by Auvitran. For details on their use, please
refer to their on-line help.
Important
: if the device is not Primary Master, the DATA/CTRL port of the AQONDA can only be used to
control the network from a PC, if all devices on the network operate with an EtherSound
technology version (kernel) higher than 3.0. If this is not the case, only the DATA/CTRL port or the
IN port of the Primary Master can be used for this purpose.
Firmware update
Digigram may decide to publish updates of the embedded firmware. It may then become necessary to upgrade
your devices. In this case, please refer to the documents delivered with the firmware update tool. These
updates, as well as the required software tool, are available on the Digigram web site.

GPIs and GPOs of various devices on the same EtherSound network can be realized by means of the EScontrol
application. The GPIO pins are labeled 1 through 8 on the rear panel as illustrated.

General Purpose Inputs (GPIs)
The GPI status can be either “1” or “0”.
Switching the GPI state to “0”:
It is read “0” as soon as the pin labeled “K” on the scheme is
connected to ground, e.g. to a pin labeled “GND”.
Switching the GPI state to “1”:
Leave pin K floating
The GPIs do not need external power supply.

General Purpose Outputs (GPOs)
The ES8 GPOs are relay outputs. They feature two pins each and are all configured the same way.
It responds to commands of configuration and management software sent by the clock source. If written at
“1”, the GPO closes the associated relay. If written at “0”, the GPO opens the associated relay.

APPENDIX D: GLOSSARY
AUDIO CHANNEL
An audio channel is a single mono audio signal. By extension, an audio channel is one of the 64 slots of an
EtherSound frame, i.e. a signal sampled at 48 kHz (or 44.1 kHz) with a 24-bit resolution. On an EtherSound
connection, 64 audio channels are available in each direction.
SWITCH
Device to connect two segments of a Local Area Network. Seeking greater filtering and forwarding speeds,
efforts were made to decrease the amount of time required to determine if a packet should be filtered or
forwarded (‘latency’) by only examining the address information contained at the start of the Ethernet frame.
The term ‘Ethernet Switch’ now is used for multiple-port-devices, which are able to filter and forward packets
at nearly the speed of Ethernet (‘wire speed’) regardless of the technique.
DAISY CHAIN
The daisy chain is a network topology where all devices are linked "serially".

GPIOs
General Purpose Inputs Outputs. AQONDA 8 and AQONDA 16 each feature eight GPIs and eight GPOs.
GPOs can be fully configured to remotely control external devices. GPIs can be used to receive commands
from external devices.
PRIMARY MASTER
In an EtherSound ES-100 network, the first device of the chain (the one on which the IN port is not
connected to any other EtherSound device) provides the synchronization for the entire network. This device is
called ‘Primary Master’.
18
RING
A ring topology may be used in order provide redundancy and thus increase reliability. This topology is to be
considered an extension of the daisy chain topology, where the last device is physically connected to the first
one. The priority “Preferred Primary Master” is defined by the network dministrator through the of
EtherSound control software.
Embedded
control
Preferred
Primary Master
• In case of a cable malfunction, the first device following this failure is then automatically designated
“Primary Master”. The network remains entirely functional, it there no audio signal loss.
• In case of a device malfunction, the same recovery mechanism applies, but - obviously - the audio
connected to the defective device will be missing.
STAR
The Star is a network topology where all devices are connected to a same unit (a switch in the following
picture) that handles all communications. A star topology is able to transmit easily and efficiently the
EtherSound channels towards a great number of destinations. However, it has to be kept in mind that in this
case, the stream of audio data is mono-directional (from the “Primary Master” towards the other devices).
