Until release 3.0 only maximal seven Audio interfaces are available.
Press the Edit button to select the relevant Audio Interface and define the de-
sired Assignment to the interface.
The Default Settings key assigns the most useful default setting to the inter-
faces.
The Allow multiple assignment of Audio Lines (inputs will be mixed) option
enables an assignment to be set multiple times to different physical interfaces.
The On Air signal can be output, e.g. to the AES/EBU/ANALOGUE Module
left and AES/EBU/ANALOGUE Module right outputs simultaneously.
If a function is used several times for different outputs the related input sig-
nals are mixed additively.
In the above mentioned example On Air, the back signal to the caller is gen-
erated out of the input signals of the left and the right channel of the
AES/EBU/ANALOGUE Module.
FIG. 67
ASSIGNMENT OF THE AUDIO INTERFACE FUNCTION
Depending on the configuration of the systems the following assignments are
possible:
The assignment applies always for the input and the output simultaneously.
– PRE TALK with Handset
– PRE TALK without Handset
If the Pre Talk function is defined to a digital Audio interface (PRE TALK
without Handset), the Handset can only be used if the Audio interface Mas-
ter/Slave: Analogue Audio for Pre Talk (PRE TALK with Handset) is config-
ured. The system chooses the appropriate Audio interface automatically
when selecting the Pre Talk source (see CHAPTER 7.5.1.1, page 45).
– HOLD: feeding of a separate Hold signal. For this, please pay also atten-
tion to the configuration of the Hold signal source (see CHAPTER 7.7.3.10,
page 87).
– ON AIR: output of the mixing signal of all callers in the On Air mode. At
the input the programme signal without caller should be feeded.
