Cascading the R2
This chapter explains the fiber interconnection possibilities between several R2 matrixes,
and guides you through a setup process of a project with 5 R2’s cascaded with each other
by means of the fiber interconnection interface.
Principle
The (optional) fiber interconnection interface makes it possible to transfer 8 stereo audio
signals and one data channel over one single fiber optic conductor. The data channel
is transmitted automatically and can’t be configured by the user. The 8 stereo audio
channels which should be transfered over the fiber conductor can be configured by the
user.
The fiber interconnection interface of the R2 works like a ring network. This means that
every R2 has one fiber input and one fiber output. This ring must be closed in all cases and
this can be done by connecting the output of the first R2 with the input of the second R2.
The output of the second R2 should be connected with the input of the third R2, and so on.
At the end, the output of the last R2 has to be connected with the input of the first R2. This
way, a ring is closed and the network is completed.
To control all the functions of all the R2’s in one network, only one connection with the
ethernet network of one R2 in the ring network is required. When multiple R2’s are connected
in a ring network, first a selection box will be displayed whereby can be selected which R2
you want to control.
Each R2 can transfer one or multiple of his input channels through the fiber ring network.
This can be any input of the R2 (Line input, PI audio input, Digital input, ... ). The selection
of which input signal should be transfered over the fiber ring network can be selected in the
“Setup” menu, after selecting the “Fiber settings” window.
Every signal which is received through the fiber ring network can be used as a regular input
just as all the other inputs, can be selected through the wall panels, and can be patched to
any of the output zones.
When an R2 transfers an audio signal over the fiber ring network, there is the possibility to
transfer the signal to all R2’s in the same ring network, or to transfer the signal only to the
next R2 in the ring network. If the signal is only needed for the next R2 in the ring network,
the second R2 can use this channel to transfer another signal to the third R2, and so on...
