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" port receives the EtherSound stream (from devices located
"upstream") while the "OUT" port forwards it to the next devices (located "downstream"); see the
document 'EtherSound Overview' 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.
7. Power supply
Power plug MUST be earthed properly.
