Putting into operation
5.6.1 ... without AES/EBU/ANALOGUE module
In this wiring exemple (Fig. 11, page 32) a Pre Talk, a separate Hold and an On
Air Audio interface are used. A fourth Audio interface is also available in the
Slave 3 System for, e.g., an alternative On Air or Pre Talk Line (see CHAP-
TER 7.7.3.1.2, page 60).
The function of the relays can be programmed as desired (see CHAPTER
7.7.3.15, page 102). Useful is e.g., the use of a relay for incoming calls and for
operating the mixer as soon as a line is switched to Pre Talk or On Air.
For redundancy purposes, a MAGIC Hybrid Keypad can be connected in paral-
lel to the Master System. This keypad ensures that if the PC crashes, the caller
lines can still be operated.
