APPENDIX D: GLOSSARY

AUDIO CHANNEL
An audio channel is a single mono audio signal. By extension, an audio channel is one of the 64 slots of an
EtherSound frame, i.e. a signal sampled at 48 kHz or 44.1 kHz with a 24-bit resolution.
CLOCK SOURCE
The first EtherSound device in the network is called the Clock Source. As well as being a source of audio for
the network, the Clock Source provides the commands and the clock for audio channel synchronization.
The Clock Source may also serve as the link between the EtherSound network and configuration software
running on an external computer, connected to its Ethernet IN port.
DAISY CHAIN
The daisy chain is a network topology where all devices are linked "serially".

GPIO
General Purpose Inputs Outputs. Each ES8 device has four GPIs and four GPOs. GPOs can be fully
configured to remotely control external devices. GPIs can be used to receive commands from external devices.
