6.7.1 Analog Interconnections
Figure 38 is an illustration of Class A and Class B wiring from the analog audio controller to analog audio risers that are in turn connected
to TICs or the Network Audio Riser Controller Module.
Note: Old legacy 0566-218 Analog Audio Controller was replaced due to component obsolescence. The replacement board is the
0566-1011 Analog Audio Controller. It is functionally equivalent to the legacy board.
Note:
1. Leave the 4.7 K, ½ W resistors (378-056; yellow/violet/red) on the "+" to "-" terminals of unused contacts.
2. All wiring is 18 AWG to 14 AWG twisted-shielded pair.
3. Audio wiring is not to be mixed in the same jacket with other wiring (including other audio wiring).
4. AC voltage rating: 10 VRMS (maximum).
5. DC voltage rating: 1 VDC (maximum).
6. Maximum number of analog interface cards per audio riser: 31.
7. All wiring that leaves the building requires the 2081-9044 Over voltage protector at each entry or exit to the building.
8. Maximum wire distance: 10,000 feet (3,048 meters).
9. Wiring must be free of all grounds.
10. Set audio input card jumpers as shown in Aux Audio Input Module Installation Instructions 579-160 .
