This section describes the Class A and Class B connections from audio controllers to audio risers,
which in turn connect to a TIC or Network Audio Riser Controller Module. Wiring configurations
are shown for both analog and digital controllers and risers.
Figure 8 is an illustration of Class A and Class B analog wiring from the analog audio controller to
audio risers connected to TICs or the Network Audio Riser Controller Module.

Overview
Analog
Interconnections
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 (0.8321 mm
2
) to 14 AWG (2.081 mm
2
), 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 Overvoltage 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 “Configuring the Audio Input Card.”
11. All riser wiring is supervised and power-limited.
