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!

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.

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 enclosed CD-ROM and on our web site.

The network connections are established via two Neutrik

EtherConTM RJ45 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

EtherConTM 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.

On ES881v2, between 44.1 kHz and 48

Preset efault value is 48 kHz.

Note: These operations require opening of the cabinet and shall be done by qualified personnel only.
