I thought you had a young assistant doing this work for you Demetris  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft. Lauderdale, FL, USA Registered: Jun 2001 posted 10-04-2010 02:56 PM                     Cable lube is so cheap.....I usually supplied the lube as part of our cable shipment for penny pinching electrical contractors. Most of our jobs had 12/4 jacketed cable....you guys can play with your twisty wire stuff  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Size the pipe correctly...observe code on the number of 90s before a pull box and yes, use lube...it isn't that bad. Belden has different jacket colors for their "speaker" cables so one can have everything pretty much IDed. Then again...if you don't mind Cobranet...using something like QSC's Basis will make pulling speaker cables a snap...just pull a Cat5 cable between the boxes...leave the amps behind the screen and run short speaker lines. It will be hum/noise free and the speaker runs will be short and cheap. Steve  |  IP: Logged Sam D.

I have not pulled speaker wire for some time. Richard, It's not the price of the lube, it's the mess. Steve, In a perfect world you get to size the conduit; in real life where we all have to live, we are working with what is already there as in a remodel.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I also acknowledge that some customers will not pay for a better job...they are normally not worth the time spent too...but that is another topic all together. A most recent job I did use the Cobranet solution due to, in part, conduit limitations. It worked perfectly! (QSC Basis). The system had three 4-way stage speakers and four subs. It was really cool not having to pull all of the heavy wire. And, as luck would have it...it also saved us hum issues since the building didn't have a real ground (found that one out, after the fact when it showed itself in other areas).

Not sure the brand of wire, but it was 4 conductor, twisted pair 12GA. This was before I was finished, so I hadn't finished cleaning up all the wiring yet, plus the video guys were running cables through my racks. After I identified the lines, I would just use a sharpie and mark the cables. Front of rack. It was during construction, and I would cover the equipment when I wasn't working on it.  |  IP: Logged Richard Hamilton Phenomenal Film Handler Posts: 1341 From: Evansville, Indiana Registered: Jan 2000 posted 10-07-2010 04:19 AM                     Here is an Article in Systems Contractor News in July 2002 about the system from my previous post.
