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 bi-
directional 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!
