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).
