D i g i g r a m Thank you for purchasing Digigram EtherSound ES220(-L)! EtherSound ES220 and ES220-L are Digigram products incorporating the EtherSound technology. They allow to easily and economically insert or extract two digital audio channels (2 + 2 in the case of ES220) from an EtherSound network using standard Ethernet components (cables CAT5 and switches). ES220 transforms two analog audio signals into two EtherSound channels and two EtherSound channels in analog audio signals, while ES220-L is configurable via jumpers: it either converts two analog audio channels into digital audio and inserts them into an EtherSound network, or it extracts two digital channels from the network to convert them into analog audio signals. Both feature GPIOs and take advantage of EtherSound's simple, nearly instant set-up. EtherSound ES220 and ES220-L allow audio distribution with a flexibility going well beyond the possibilities of analog audio installations. Routing can be adapted remotely to the changing needs of the audio installation. For more information on the EtherSound technology we invite you to visit our web site where several documents (in English) are available for download. 6

D i g i g r a m ES220 & ES220-L rear panels Audio connector 1Network connectors3GPIO connector 2Power supply4 1. Audio connectors On ES220, a Sub-D 15 connector is used to input two balanced analog signals and to output two balanced analog signals. On ES220-L, only one of these two functions is accessible depending on the configuration selected (for connector pinout see appendix C). 2. Network connectors These two EtherConTM NeutrikTM RJ45 connectors allow of a steady and reliable connection to the EtherSound network. The “IN” port receives the EtherSound stream (from devices located “upstream”) while the “OUT” port forwards it to the following devices (located “downstream”); see the document “EtherSound Overview” for more details on upstream/downstream concepts (available on our web site). 3. GPIO connector This connector allows setup of external control and monitoring devices through configurable and protected General Purpose Inputs and Outputs. See appendix D dedicated to the GPIOs for more details. Note: the GPIO port is managed by configuration software only. 4. Power supply 4-pin Mini DIN connector (for the connector pinout see it appendix G). 8

ES220 & ES220-L Ethernet Audio Bridges INSTALLATION Before mounting devices in a rack… Internal settings Note: These operations require opening of the cabinet and shall be done by qualified personnel only. Setting the EtherSound channels (ES220 and ES220-L) Four decimal rotary switches on the EtherSound board inside the device determine whether the assignment of the EtherSound channels to the inputs or outputs of ES220(-L) is done locally or remotely by configuration software. (to modify this setting, see appendix B). By default, the devices are parameterized for software control (factory setting). Input/Output configuration (ES220-L only) On ES220-L, a jumper makes it possible to parameterize whether the equipment adds two channels to the network EtherSound (Master) or restores two channels (Slave); for more details, please refer to appendix E of this manual). By default, the devices are parameterized in order to restore two channels from the network (Slave). Nominal input level The nominal input level can be configured via internal jumpers. The default value is + 4 dBu, it can be set to -10 dBu (for more details, please refer to appendix E of this manual). Connecting your EtherSound device It is recommended to establish all connections before powering up the device. Power supply Before plugging the power cord, make sure that: • the power cord is not damaged • the AC outlet used is properly earthed. Note: 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. 9

D i g i g r a m Network The network connections are established via two NeutrikTM EtherConTM RJ45 receptacles. Connection is very easy: use the connector labeled “IN“ to input the EtherSound stream, the connector labeled “OUT“ to send the EtherSound stream to other devices. The NeutrikTM 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. If you use an ES220(-L) as Primary Master, the “IN” port may be connected to a control computer for system configuration (in this case, a crossover cable is required!). Example 1: point-to-point transmission of two audio channels This application is very easy with EtherSound ES220 and ES220-L. Connect a standard Ethernet cable between the “OUT” port of an ES220 or an ES220-L configured as Master and the “IN” port of an ES220 or an ES220-L configured as Slave. Select the EtherSound channels on both devices in accordance with each other (see chapter “Setting the EtherSound channels“). Example 2: adding more devices You can easily insert further ES220(-L) devices to build a simple daisy chain. There are only two rules to follow: The first device in the chain is necessarily the Primary Master, typically an ES8in, ES8mic or ES220(-L). Install the devices in the chain starting from the Primary Master; connect its “OUT” port to the “IN” port of the next device, connect its “OUT” port to the “IN“ port of the following device, and so on. Example 3: more complex architectures System topology may be daisy chain, star, or a combination of both. The first device in a network, such as an EtherSound ES220, provides the master clock for the entire network. Connect its “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 (328 feet). Intermediate switches or fiber optic links may be used to considerably increase this distance. All EtherSound devices “downstream” from an audio source can play the corresponding network channel. 10

ES220 & ES220-L Ethernet Audio Bridges Connecting a computer to manage the EtherSound network To connect a PC directly to an ES220(-L), it must be equipped with a network card. Use a crossover Ethernet cable to connect the network card to the “IN” port of the Primary Master. You can also access the Primary Master through a conventional Ethernet network; in this case, use a standard Ethernet cable (e. g. connected to a switch) Audio The pinout of the connector is depicted on the label on top of the device: These balanced inputs/outputs are can be used with unbalanced audio sources and destinations: just wire both cold pin and ground pin on ES220(-L) to the ground of the unbalanced signal and the hot pin to the signal. Note that in this case the unbalanced output signal is multiplied by two (+6 dB), it is thus necessary to reduce the output gain (-6 dB) in order not to saturate the signal. By default, the nominal input/output level of an ES220 or an ES220-L is +4 dBu. On ES220(-L) the nominal input level can be set to +10 dBu via internal jumpers (for more details see appendix E: Setting the internal jumpers). The values of the nominal output level can be adjusted for each channel through management software and stored in the ES8out device. GPIO ES220 and ES220-L are shipped with four GPIs and four GPOs on a 15-pin Sub-D connector. For details see Appendix D. Note: the GPIO port is managed by configuration software only. Remote set-up by means of configuration software To manage the device remotely using configuration software, the rotary switches must be set manually to any number ranging between 65 and 99 (factory setting). Use of the configuration software allows for advanced channel allocation; for software details, please refer to the online help file. ES220 and ES220-L can be managed by Digigram's configuration software EScontrol. Please download the EtherSound driver and the EScontrol application from www.digigram.com and run EtherSoundDriverXXX.exe first to install driver, then EScontrolXXX.exe (where XXX indicates the version number). For each software package an InstallShield Wizard will guide you through the installation process. Note: This operation is only necessary if software control is needed. 11

D i g i g r a m ES220 and ES220-L may also be managed through configuration software edited by Digigram development partners. To uninstall the software go to Add/Remove programs in the Windows Control Panel. Firmware update Digigram may decide to publish firmware updates. It may then become necessary to upgrade your devices. In this case please refer to the respective documentation provided with the firmware upgrade tool. 12

In every pair, the rotary switch on the left is the “tens“ position and the rotary switch on the right is the “ones“ position. Channels 01 to 64 are reserved for manual set-up, channels 65 to 99 set the device remote configuration. Software configuration mode is indicated by a lightened red electroluminescent diode. In position 00 of the rotary switches the audio is “Mute”: in input mode no EtherSound channel inserted, in output mode no sound played. To manually set the EtherSound channels to be used by the device, configure the number of the EtherSound channel to be assigned to the first analog input or output. Example: to assign channel no. 24 the first EtherSound channel, set the left switch to “2”, the right one to “4”. The other channel is assigned subsequently. (In our example: 25) Note: On ES220-L, only one pair of rotary switches is active, depending on the selected configuration: inputs OR outputs. 17

ES220 & ES220-L Ethernet Audio Bridges APPENDIX D: GPIO CONNECTOR ES220 and ES220-L have four TTL 5 V compatible GPIs and four open collector GPOs. GPIs allow sending commands to the EtherSound configuration software, GPOs can be used by the EtherSound configuration software for remote control of external devices. General Purpose Inputs (GPIs) Schematic diagrams show the particular design for each GPI. The GPI status can be either 1 (=ON) or 0 (=OFF). It is read at “0” as soon as the system connected to GPI provides a tension higher than 2.5 V without ever exceeding 5 V. Otherwise, GPI is read at “1”. Note: Pin 1 delivering +5 V electric potential and pin 6 being connected to ground (0 V), they have to be used in the configuration of the GPIs. GPI GPI status General Purpose Outputs (GPOs) The ES220(-L) GPOs are “open collector” outputs. They use the same reference for 0 V and the same protection reference. The protection reference must be connected to the highest potential that may ever be connected to GPOs. The GPOs respond to commands of the configuration and management software sent by the Primary Master. If written at “1”, the GPO closes the linked open collector. If written at “0”, the GPO opens the linked open collector. Note: Pin 6 being connected to ground (0 V) and pin 11 being used as protection reference for the GPOs, they have to be used in the configuration of the GPOs.

ES220 & ES220-L Ethernet Audio Bridges APPENDIX E: SETTING THE INTERNAL JUMPERS. These settings shall be executed by qualified personnel only! Tools required: • a #1 Pozidriv screwdriver • an ESD-preventive wrist strap • a small flat blade screwdriver Electrostatic discharge (ESD) can damage several components on the board. To avoid such damage in handling the board, take the following precautions: Bring the device and everything that contacts it to ground potential by providing a conductive surface and discharge paths. As a minimum, observe these precautions: • Disconnect all power and signal sources. • Place the device on a grounded conductive work surface. • Ground yourself via a grounding wrist strap or by holding a grounded object. • Ground any tools that will contact the device. • Unscrew the eight flat-head Pozidriv screws (four on top-side, four on bottom-side) counterclockwise and open the cabinet. IN/OUT selection (ES220-L only) 4IN/OUTselection(ES220-L only) With this jumper ON, ES220-L extracts two digital channels from the network to convert them into two analog audio signals. Without this jumper, ES220-L transforms two analog signals into EtherSound channels and the inserts them into the network. 21
