AES/EBU/ANALOGUE Module

The optional AES/EBU/ANALOG Module extends the system by two further
analogue or two digital AES/EBU inputs and outputs (switchable). Via the
MAGIC TOUCH software, each Audio interface can be configured as desired
to the greatest possible extend.
Subsequent installation of the module can only be made in our factory.
Therefore, three analogue inputs (Audio interface already existing in the sys-
tem + two further modules) and three analogue Audio outputs are available
when selecting the analogue input Audio interface (see Fig. 5). The two ana-
logue outputs of the modules are, additionally, activated in parallel, on the
digital Audio interface of each module.
FIG. 5
If the digital inputs of the module are selected (see Fig. 6), one analogue and
two digital Audio inputs are available as well as two digital and one analogue
output. The digital outputs of the module are additionally activated in paral-
lel to the analogue Audio interfaces of the module. The digital input as well
as the output have their own sample rate converter. The word clock can be
read or fed in via the BNC connector.
Please note that the two inputs/outputs are physically one AES/EBU inter-
face. The outputs are always connected in parallel.
FIG. 6
Maximum number of Audio interfaces
The maximum number of available Audio interfaces depends on the number
of B channels. The sum of the Audio interfaces and B channels (visible chan-
nels + call forwardings) is limited to 24 (e.g. 12 Audio interfaces and 12 B
channels). The maximum number of Audio interfaces can be twelve
maximum build (see CHAPTER A3, page 141).

Until release 3.0, a max. of only seven Audio interfaces are available.
