I'm setting up a PA system (LabGruppen 2k watt power amp to two Bose 802 Panaray 8ohm speakers) over 120' 12GA speaker cables in a temporary outdoor tent for graduation ceremonies over three days. Fire code indicates that the tent must be equipped with emergency exit signs, (even though there are no side panels,) so 120v AC power lines are distributed around the inside perimeter of the tent to power the signs, with a few upward floods to provide ambient illumination.
In years past, I've laid the speaker cables (50') on the ground for each event, and removed them in between to stow securely and prevent damage, etc.
This year our school has doubled the footprint of the tent, in addition to being square vs. rectangular, so I need a far longer cable run. Installing the speaker cables on the inside perimeter of the tent alongside the power lines would save me a lot of time in setup and breakdown, and the electricians can to the heavy lifting for me!
I've done a fair amount of research on the net about running lengthy speaker cables parallel to AC cable and the possibility of interference with the sound, (buzz, etc,) and most of my findings indicate that there won't be a problem with this. In essence, the shielding in the cable and the signal level is high enough to prevent interference, and the 8ohm characteristic of the speakers help as well.
Barring human error (electricians by accident cutting the cable casing and exposing the shielding) and acts of nature (unexpected violent thunderstorms) should I, or should I not, have the speaker cables installed alongside the power cables on inside perimeter of the tent?
