My church is doing much needed renovations. The sound is fairly good and we won't be changing much, but I'm trying to resolve some of the infrastructure problems at the same time of the renovations.
We are moving the sound booth from a second floor location to the main floor. The current conduit is running through the attic/crawl space to the stage, down a raceway to the stage. Moving the sound booth to the main level means either extending that conduit down the back wall with cable extensions or new cable runs, or installing a new conduit path.
During they renovations, they are moving the duct work from the floor to the ceiling. The current duct work is rusted and letting water in which makes the room a sauna when the heat is on. The old duct work is going to be filled with concrete (probably not the entire duct, just the openings). This duct makes a perfect straight path from the sound booth location to the stage.
Is there flexible conduit I could run down the ductwork to the stage? I need flexible because of the angle at which I have to enter the duct and a smooth wall would be nice.
What size conduit? I would like 16 lines of audio plus 5 returns, video cable, network cable, and room to spare.
Thanks, in advance for any suggestions.
