O2 ARC Indoor / Outdoor Loudspeaker Installation Guide
results, avoid running speaker wire near AC wire, as it may induce a 60Hz hum in the audio signal. In new construction, it’s a good idea
to run the speaker wire after the AC wiring has already been completed allow you to route the speaker wire away from the AC wiring.
If speaker wire and AC wiring must run parallel, install the speaker wire within a steel conduit. Note that low voltage wiring (doorbell,
intercom, telephone, security, network, etc.) can also induce hum.
Drill with Caution.
Remember, these are only suggestions – like a run-a-way bride we won’t commit. There are building codes and best practices to be
followed – be sure you are familiar with them. When drilling holes through wall studs or ceiling joists, use a drill bit that is (sharp) wider
than the speaker cable that will be routed (pulled) through them. Always drill through the center of the stud or joist. If the hole must be
drilled within one inch of the edge of a wall stud, add a nail plate to the drywall side to protect the wire from possible nails and screws
put in the wall later. Line up the holes in the studs or joists as you go, so that pulling the wire through them will be easier. Maybe you
consider hiring a professional installer and see a movie with some new friends instead.

horizontally or vertically and have some positioning wiggle room. The bracket is designed to allow the speaker to rotate so you can aim
