Long Cable Runs with Separate Cable for DC Power and Audio
In this section:
For installations where Belden 1502 is not feasible, or for installations that require cable runs longer than 150 ft, separate cables for DC power and balanced audio may be used: a large-gauge cable for DC and a high-quality, balanced audio cable for audio. The separate cables attach to the Phoenix connector at the loudspeaker as shown in the figures below. DC power cable runs longer than 150 ft require cable gauges larger than 18 AWG; see Cable Lengths and Cable Gauges.
