Interconnections
Figure 4-19 is an illustration of Class A and Class B wiring from the analog audio controller to
risers connected to 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.
Figure Notes:
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. The maximum number of analog interface cards per audio riser is 31.
7. All wiring that leaves the building requires the 2081-9044 Overvoltage Protector at each entry or exit to the building.
8. The maximum wire distance is10,000 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.
11. All riser wiring is supervised and power-limited.
