CONTROLLER user manual
The L-Net port delivers power to remote devices. The maximum power capacity of each L-Net port is
500mA (protected with a, slow type, automatic fuse). L-Net devices of different types have different average
power consumption, which may vary from 30mA up to 180mA. This implies limitations in terms of the
maximum number of devices powered over the L-Net.
NOTE: Consider power consumption of L-Net powered devices!
In the table below, you can see an example of power consumption over the L-Net. This example showcases
the usage of a single type of L-Net device (4E-FMTC microphone console with 180mA current consumption
@24V), where the units are distributed equally over the L-Net cable.

Global network

G-Net is a redundant network ring where multiple Controllers may be connected into one system. It is used
to reliably synchronize data between all connected devices and for multi-channel live audio transmission
with very low latency. G-Net works as a redundant double ring between Controllers, which keeps the global
system intact in case of single link failure.
To create a redundant G-Net ring between multiple Controllers, connect both G-Net ports between every
unit in the network, so that you create a closed ring.
Power over G-Net (active by default) is dedicated to supply devices connected to the G-net port, such as
fiber transceivers (FSC).
