Wichtige Sicherheitshinweise

vor Inbetriebnahme des Gerätes sorgfältig lesen!

Befolgen Sie die Anweisungen und bewahren Sie sie für spätere Fragen auf! Bei Schäden, die durch

Nichtbeachten dieser Bedienungsanleitung verursacht werden, erlischt der Garantieanspruch!

Throughout this manual,

the lightning bolt triangle is

used to alert the user to the

risk of electric shock.

The exclamation point

triangle is used to alert the

user to important operating

or maintenance instructions.

Do Not Open the Cabinet

There are no user-serviceable

components inside this product.

Opening the cabinet may present a shock hazard,

and any modification to the product will void

your warranty. If it is necessary to open the device

for maintenance or advanced configuration

purposes, this is to be done by qualified personnel

only after disconnecting the power cord and

bles!

Power supply

The device is to be connected only to a

power supply as specified in this

manual and marked on the equipment. This

equipment must be earthed!

ma

Do not block any of the ventilation openings!

Humidity

To reduce the risk of fire or shock, do not expose

this device to rain or moisture. Do not place

objects filled with liquid on this device.

Installation Location

To ensure proper operation and to avoid safety

hazards, the device must be installed in a 19“ rack

mount chassis. If this is not possible, place it on a

firm and level surface. Avoid installation in

extremely hot or cold locations, or in an area that

is exposed to direct sunlight or heating

equipment. Avoid moist or humid locations.

Cleaning

Clean only with a soft, dry cloth. If necessary,

after disconnecting the unit’s cables, wipe it with a

soft cloth dampened with mild soapy water, then

with a fresh cloth with clean water. Wipe dry

immediately with a dry cloth. NEVER use

benzene, aerosol cleaners, thinner, alcohol or any

other volatile cleaning agent. Do not use abrasive

cleaners, which may damage the finish of metal or

other parts.

Refer all servicing to qualified service

personnel.

Servicing is required when the apparatus has been

damaged in any way, such as power supply cord

or plug is damaged, liquid has been spilled, the

apparatus has been exposed to rain or moisture,

does not operate normally, or has been dropped.

Moving the device

Before moving the unit, be certain to disconnect

any cables that connect with other components.

Gerät nicht öffnen

Öffnen des Geräts kann eine

Gefährdung durch Stromschlag und

Erlöschen der Garantie zur Folge haben.

Reparaturarbeiten und Änderungen der

Hardwarekonfiguration dürfen nur von

qualifiziertem Personal nach entfernen der Strom-

und Netzwerkkabel durchgeführt werden.

Stromversorgung

Das Gerät darf nur mit der in dieser

Bedienungsanleitung und auf dem

Gerät angegebenen Stromversorgung

betrieben werden. Erdung ist zu gewährleisten!

Belüftungsschlitze nicht verdecken!

Wasser und Feuchtigkeit

Um Brand- oder Stromschlagrisiken zu

vermeiden, darf das Gerät nicht mit Feuchtigkeit

in Berührung kommen.

Aufbau des Geräts

Um den einwandfreien Betrieb zu gewährleisten

und Sicherheitsrisiken zu vermeiden, muss das

Gerät in einem 19-Zoll Baugruppenrahmen

montiert werden. Nur wenn dies nicht möglich

ist, stellen Sie das Gerät auf einen festen,

waagerechten Untergrund. Meiden Sie Standorten

in den Nähe von Wärme- oder

Feuchtigkeitsquellen sowie direkte

Sonneneinstrahlung.

Reinigen des Geräts

Säubern Sie das Gerät nur mit einem weichen,

trockenen Tuch. Bei Bedarf verwenden Sie ein mit

mildem Seifenwasser befeuchtetes Tuch, nachdem

Sie die Netzanschlusskabel aus der Steckdose

gezogen haben, anschliessend ein weiches, mit

klarem Wasser befeuchtetes Tuch. Trocken Sie

das Gerät sofort im Anschluss. Keinesfalls Benzol,

Verdünner oder sonstige starke Lösungsmittel

oder Scheuerreiniger verwenden, da hierdurch

das Gehäuse beschädigt werden könnte.

Lassen Sie etwaige Reparaturen nur von

qualifizierten Fachleuten durchführen!

Sollten das Netzkabel oder der Netzstecker

beschädigt sein, oder sollte das Gerät selbst

beschädigt worden sein (z. B. durch Eindringen

von Feuchtigkeit durch Fall auf den Boden), oder

sollte es nicht ordnungsgemäss funktionieren oder

eine deutliche Funktionsabweichung aufweisen,

so ist es von qualifizierten Fachleuten zu

reparieren.

The cable type most commonly used today is CAT5e. For more detailed information, please refer to the

document “Building ES Networks”, available on the enclosed CD-ROM and on our web site.

The network connections are established via two Neutrik

receptacles. Connection is very easy: use the connector labeled “IN” to connect the

descending EtherSound stream (downstream, coming from the ‘Clock Source’), the

connector labeled “OUT” to connect the ascending EtherSound stream (‘upstream’).

The Neutrik

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 audio channels

This application is very easy with EtherSound ES881v2, ES1241v2, and ES16161v2.

Connect a standard Ethernet cable between the “OUT” port of the first Ethernet bridge to the “IN” port of the

second Ethernet bridge. Bring into line the EtherSound channels on the two devices (see the on-line help of

the configuration software).

Example 2: more complex architectures

System topology may be daisy chain, star, ring, or a combination of star and daisy chain. By default, the first

device in a network, such as an EtherSound ES881v2, provides the master clock for the entire network. This

device is called ‘Clock Source’. Note that in a ring configuration you must configure a device as Clock Source

(this is done by software, the device is then called ‘Preferred Clock Source’). Nevertheless, you have the

possibility to synchronize the ‘Clock Source’ device on an external clock by using the ‘Word Clock In’ input

and by then providing this clock to the EtherSound bridges downstream from the ‘Clock Source’ passing

through the ‘Word Clock Out’ outputs.

Connect the “OUT” port with the “IN” port of the following EtherSound device.

Repeat this step for each device in the network. The maximum distance between two devices is 100 meters

(≈330 feet). Intermediate switches or fiber optic links may be used to considerably increase this distance.

The ES8 GPOs are relay outputs. They feature two pins each and are all configured the same way. Pins 1 & 2

belong to GPO #1, 3 & 4 to GPO #2, 5 & 6 to GPO #3, and 7 & 8 to GPO #4.

Select sampling frequency

This jumper allows for modification of the ES881v2, ES1241v2, and ES16161v2 sampling frequency. The

default value is preset to 48 kHz. It can be set to 44.1 kHz. Note that this setting is effective only if the device

is the Clock Source of the EtherSound network. In all other cases the sampling frequency is determined by the

incoming EtherSound stream (synchronized on the Clock Source clock). Modifications on devices other than

the Clock Source will be ignored.

The double Sub-D connectors

The audio signals on the inputs and outputs are available on the 25-pin Sub-D connectors on the back panel

of the device. Every connector is composed of two banks, each of those receiving four digital AES/EBU stereo

input or output signals. The ‘hot’ signals (+) are located on the upper pins of the Sub-D, the ‘cold’ signals (-)

on the lower pins. The diagram and the tables underneath show the default wiring:

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.

CLOCK SOURCE

The first EtherSound device in the network is called the Clock Source. As well as being a source of audio for

the network, the Clock Source provides the commands and the clock for audio channel synchronization.

The Clock Source may also serve as the link between the EtherSound network and configuration software

running on an external computer, connected to its Ethernet IN port.

DAISY CHAIN

The daisy chain is a network topology where all devices are linked “serially”.

Clock

Source

GPIO
