That is the microphone cable that I have bought.
Seems okay to me... So I will run this cable this weekend.

Could you tell me, what will be the reason not to fly sub?
There is no place to put the sub in the floor, thats why I come up with the flying idea.... will that be really serious problem to flying the sub?

I've seen some church flying the sub...(really high ceiling..)

Thank you!

And I ordered 7 x 2female microphone wall plate. I will use about 120ft cable for all the wall plate to mixer.

120ft is okay to use? Do I need to use any repeater?


120' is no problem for mic lines, no repeaters needed. What is important is that you use the proper wire such as this:  http://www.markertek.com/Cables/Bulk-Wire-Cable/Bulk-Audio-C able/West-Penn-Wire-Corp/291-BLACK.xhtml?WP-291-1000YW

Stay away from foil shielded cables for snake runs. They're ugly when exposed for termination at the mixer side and are not numbered. Jacketed numbered multi pair (14?) is what you'll need like maybe http://www.fullcompass.com/product/251795.html.

Hope this helps.

WHOA!!!!!!! Are you going to run this cable as a snake run from stage to sound room? If so that's totally the wrong cable! This is for mic and instrument and not for snake run. What you need is multi pair snake cable such as this http://www.fullcompass.com/product/251795.html  

And as for flying speakers, especially subs, if not by a certified rigger you're asking for huge liability issues. I think Brad can address this better.

I would argue that for installations the individual cables are often a better choice than snake cable.  If you have a number of inputs at one location, something like 8 mics on a single plate, then a multipair with an overall jacket for that location may make sense.  But there is no reason you could not run multiple individual runs and often some advantage in doing so.

What I don't think has been addressed is issues such as cable ratings.  If the cabling is all in conduit then no special rating may be required.  If you run the cabling above ceilings or in walls without conduit then it needs a certain rating.  If the above ceiling space is a plenum space then the cabling needs a different rating.  This applies whether running individual cables or a bundled snake cable.

Another though for installed systems and regardless of whether running snake or individual cables is to run a few extra cables to accommodate some expansion and provide redundancy.  One of the potential disadvantages to snake cables is that if you run an 8 pair snake for 8 connections and any single pair ever goes bad then you have to replace then entire snake.  So think about whether a few redundant runs might be worth the additional initial cost.

I can address it as far as saying that I've been designing and installing audio systems professionally for over 25 years and was one class short of potentially qualifying for a dual major in Civil Engineering (my major was Acoustical Engineering), but I still wouldn't try to fly things myself.  I don't have the specific training, experience, liability coverage, etc. that are required to be a qualified rigger.  But I know people who do and strongly advise that you use someone like that.

Danny, you messed up. That is not the right cable, because it does not have a ground. If you use that cable you will be doing your church a serious diservice.

The main reason is most the subs at the price point you describe are not designed to be flown. Flying speakers that are not design to be is very dangerous, particularly when the speaker is a heavy sub.

Subs do not take that much room, I am sure you can find a space.

Sidney, not sure what you are talking about here. Almost all install mic cable is a foil shield, including the IJIS you describe.

I thought the shield cable, I could use that as ground.
If I use this as a microphone cable, It will not work? or you mean, is this bad cable?

Yes, you should be able to use the shield as the pin 1 ground connection.

I looked closer at the cable and although you likely would be able to use the spiral shield as the ground, I would still recommend getting the correct cable. Besides the ground, it is also a rubberized jacket that makes it take up more room, and more difficult to pull. for the small cost I would get the right stuff. It will make the soldering go quicker as well.

It is not that that cable is bad, just not the best choice for your application.

Added: BTW- that same site has speaker cable for a good price-  http://www.cablewholesale.com/specs/bulk-speaker-cable/10g3- 291sf.htm

Thanks Gary.

By the way, can you recommend any microphone cable for future reference?

We also already have snake cable which is pre-made.
Our mixer channel is 32 and I am not willing to plug the cable from the wall plate to snake cable.

What I will do was to run the cable from the wall plate to mixer.

The snake is already ran through the ceiling and we setup on the stage.
