Thank you for purchasing Digigram EtherSound ES8in/ES8mic/ES8out!
EtherSound ES8in, ES8mic, and ES8out by Digigram incorporate our patented EtherSound audio networking
technology. They offer the easiest and most affordable way to install and distribute up to 64 channels of
audio between up to 65 534 devices using standard Ethernet switches and cabling.
ES8in/ES8mic insert eight analog audio channels into an EtherSound network with ES8mic adding the
flexibility to connect up to eight microphones instead of the line inputs, while ES8out extracts eight analog
audio channels for playback. All three feature GPIOs and RS232 for bi-directional control and take
advantage of EtherSound's simple, nearly instant set-up.
EtherSound ES8in, ES8mic, and ES8out allow audio distribution going well beyond the possibilities of analog
audio installations and their physically defined signal paths. Routing can be adapted remotely to the
changing needs of the audio installation.

1. Device status group (two orange LEDs):
on ES8in/ES8mic
The first LED is called “Primary”. It shines when ES8in/ES8mic is the first Master device in the EtherSound
network, thus the Primary Master of the EtherSound network (see chapter on EtherSound for more details on
the Primary Master concept)
on ES8out
The first LED is called “Upstream”. It indicates that an EtherSound stream is correctly received on the “IN”
(“FROM”) port of ES8out; in normal operation mode it constantly emits light, unless the connections to the
network have not been properly established.
on all ES8 devices
The second LED is labeled “Remote” on all devices: It is lightened when the EtherSound channel configuration
is done remotely and not by the rotary switches on the rear panels.
2. Network status group
These four green LEDs indicate an activity on the two Ethernet ports (“IN” (“FROM”) and “OUT” (“TO”)); RX
flashing means that data are received while TX flashing means that data are transmitted. As the audio in the
EtherSound stream is unidirectional (from the “IN” (“FROM”) port to the “OUT” (“TO”) port), the RX of “IN”
(“FROM”) and the TX of “OUT” (“TO”) will flash most of the time during normal operation. The TX of “IN”
(“FROM”) and the RX of “OUT” (“TO”) will flash more rarely as they only concern control data (which is bidirectional on the EtherSound network).
3. Audio metering group
These eight bi-color LEDs exemplify the level of the analog signals passing into the eight channels of the
device. They change from green to red at 6 dB before clipping (i.e. “-6 dBfs”).
4. Power
This LED simply shows that the device is up and running!

1. Audio connectors
On ES8out XLR, eight male XLR-3 connectors are used to output eight balanced analog line level
signals; on ES8in XLR, eight female XLR-3 connectors are used to input eight balanced analog line
level signals, on ES8mic the input signals can be either microphone or line level. As the distinction
between in/out using female/male convention is not possible with Terminal Block models, the
serigraphy recalls whether these are inputs or outputs. Counterparts are supplied to facilitate the use
of the terminal blocks but you may buy different models at your convenience through your usual
electric parts reseller.
2. Network connectors
These two Neutrik
EtherSound network. The “IN” (“FROM”) port receives the EtherSound stream (from devices located
“upstream”) while the “OUT” (“TO”) port forwards it to the next devices (located “downstream”); see
EtherSound chapter for more details on upstream/downstream concepts.
3. GPIO connectors
These terminal blocks allow setup of external control and monitoring devices through configurable
and protected General Purpose Inputs and Outputs. See dedicated GPIO chapter for details.
Note: The GPIO ports are managed by configuration software only.
4. Serial port
RS232 interface on DB9.
Note: The RS232 serial port management requires specific software.
5. EtherSound channel positioning
These two decimal rotary switches determine whether the assignment of the EtherSound channels to
the analog inputs or outputs of ES8 is done locally or remotely through software control.
6. Ground
Connect this ground bolt to the chassis of the mounting rack for a better grounding of the electronics,
thus ensuring immunity to electromagnetic interference.

INSTALLATION
Note: To use your ES8 devices outside of fixed installations, they must be mounted on slide rails inside the rack to
insure correct support and prevent damages during transport and handling.
Before mounting devices in a rack…
Internal settings (ES8in/ES8mic only)
On ES8in, impedance and the nominal level of entry, as well as the sampling rate can be configured using
internal jumpers.
On ES8mic, only the sampling rate is configurable.
The default values are:
- Nominal input level: +4 dBu
- Impedance: 22.2kΩ
- Sampling frequency: 48 kHz.
In case you need to change the default settings, please refer to appendix B of this manual.
Note: These operations require opening of the cabinet and shall be done by qualified personnel only.
Connecting your EtherSound device
It is recommended to establish all connections before powering up the device.
Power
Before plugging the power cord, make sure that:
• the power cord is not damaged
• the AC outlet used is properly earthed.
Just like 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
chapter “Ethernet cables” in this manual.
The network connections are established via two Neutrik
Connection is very easy: use the base labeled “IN” (“FROM”) to input the EtherSound stream,
the base labeled “OUT” (“TO”) to send the EtherSound stream to other devices.
The Neutrik
disconnect the cable from the device, press the latch, then withdraw the cable while
maintaining the latch pushed.
If you use ES8in/ES8mic as the Primary Master, the “IN” (“FROM”) port may be connected directly to a
control computer for system configuration with a crossover cable
standard cables are to be used.

Example 1: point-to-point transmission of eight audio channels
This application is very easy with EtherSound ES8in/ES8mic and ES8out.

EtherSound ES8in, ES8mic & ES8out
Ethernet Audio Bridges
Connect a standard Ethernet cable between an ES8in/ES8mic “OUT” (“TO”) port to the “IN” (“FROM”) port of
an ES8out device. Select the ES8in/ES8mic and ES8out channels accordingly (see “Setting the EtherSound
channels” chapter).
Example 2: adding more devices
You can easily insert further ES8 devices to build a simple daisy chain. There are only two rules to follow:
1. The first device in the chain is necessarily the Primary Master, typically an ES8in/ES8mic.
2. Install the devices in the chain starting from the Primary Master; connect its “OUT” (“TO”) port to the
“IN” (“FROM”) port of the next device, connect its “OUT” (“TO”) port to the “IN” (“FROM”) 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 ES8in/ES8mic, provides the master clock for the entire network.
Connect the one device's “OUT” (“TO”) port to the “IN” (“FROM”) port of the following device (EtherSound
ES8in/ES8mic for inserting additional channels or EtherSound ES8out for extracting existing channels).
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.
Connecting a computer to manage the EtherSound network
To connect a PC directly to ES8in/ES8mic, it must be equipped with a network card. Use a
crossover Ethernet cable
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)
to connect the network card to the “IN” (“FROM”) port of the
Audio
Depending on the ES8 model purchased, balanced inputs and outputs are available either on eight XLRs or on
a terminal block on the rear panel. 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”, -).
The pinout of the terminal block is depicted beneath the strip:
These balanced connections are
compatible with unbalanced audio
sources and destinations: just wire
both cold pin and ground pin on ES8
to the ground of the unbalanced signal,
and the ES8 hot pin to the signal.
By default, ES8in/ES8mic nominal input level is set to +4 dBu; for details, see Appendix B.
By default, ES8out nominal output level is +4 dBu. The value can be adjusted for each channel through
management software and stored in the ES8out device.
GPIO
ES8in/ES8mic and ES8out are shipped with four GPIs and four GPOs on terminal blocks, counterparts are
supplied. For details see Appendix A.

D i g i g r a m
Serial port (RS232 on DB9)
ES8in/ES8mic and ES8out dispose of a serial RS232 DB9 male port on the rear panel. Use this port to connect
any compatible device. For pinout allocation details, please refer to the figure and table above.
Note: The RS232 serial port requires specific software.

1 not connected
2 RxD (received data)
3 TxD (transmitted data)
4 not connected
5 signal ground
6 not connected
7 RTS (request to send)
8 CTS (clear to send)
9 not connected
Setting the EtherSound channels
These two decimal rotary switches on the rear panel determine whether the
assignment of the EtherSound channels to the analog inputs or outputs of
ES8 is done locally or remotely by software control. The rotary switch on
the left is the “tens” position and the rotary switch on the right is the “ones”
position. Channels 1 to 64 are reserved for manual set-up, 0 and the
channels from 65 on set the device to remote configuration mode.
Manual set-up
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 using a small screwdriver (e. g. if you choose
channel no. 24 to be the first EtherSound channel, set the left switch to “2”, the right one to “4”). The other
channels will then be assigned subsequently (e. g. second channel = 25, third channel = 26 and so on…).
