Figure Notes:
1. All wiring is 24 AWG to 18 AWG, twisted-pair.
2. Maximum wire distance: 2,500 feet (762 meters) from digital audio controller primary to the digital audio riser card.
3. Maximum distance between subsequent nodes: 2,500 feet (762 meters)
4. Maximum line distance and capacitance between nodes:
18 AWG : 40 Ohms maximum, 0.055 µF maximum
24 AWG: 135 Ohms maximum, 0.055 µF maximum
5. All wiring that leaves the building requires the 2081-9044 Overvoltage Protector at each entry or exit to the building.
A maximum of four overvoltage protectors are allowed. Each 2081-9044 adds 6 Ohms and 0.006 µF.
6. Wiring must be free of all grounds.
7. Maximum number of digital interface cards per digital audio riser: 31.
8. All riser wiring is supervised and power-limited.
9. Audio wiring is not to be mixed in the same jacket with other wiring (including other audio wiring).
10. In applications where no Digital Audio Controller is connected to the field wiring (such as a synchronized audio
application or a non-synchronized application with multiple network microphone s), all DAR interface cards are
wired secondary to primary.
