I am going to be installing some cables for Microphones using XLR connections I am just wondering what type of cable I should be using .I have 8451 which I was told would be the right cable I just wanted a another opinion

Thanks

Belden is good. I have also used a lot of West Penn 291 and 454, Gepco 61801EZ. The Gepco is super easy to work with.
I did a lot of sound work throughout HS and college, I miss those days!

The retail electronics store that I frequent (You-Do-It Electronics) stocks Belden microphone cable and I've used it in the past (both standard & Starquad) without any problems. I've also purchased pre-made microphone cables too.

This wiring going to be run through the walls/ceiling from the jack to the equipment or are you looking for a cable from the plug to the microphone? Belden 8451 and those West Penn and Gepco equivalents are fine for premises wiring and within racks but from the plug to the mic you want something that has a better, more flexible jacket, can be coiled easily and take abuse.

Do you know how to wire XLRs?

I assumed that he is doing permanent install work. For portable mic cables, I like Belden, Canare starquad, or Gepco M1042.

Yes as Hal said this wire is fine for permanent install as long as there is not much that can interfere with it. I always like the double shield with braid and foil and if this a portable cable it needs to be more flexible like Hal said and a better shield.

Yes .I need to runn (4) mic cables approx 50 feet thru the ceiling and down the wall for a permanent installation I am going be to using a quad XLR wall plate male on one female on the far end I also have to run (2) speaker cables as well .I did go to You Do It for the cable and they recomended 8451.it just seemed kind of thin to me but it's shielded 22 gage miniture audio & sound control cable .I just want to make sure that there isnt something ele that I should be using

Originally they just wanted me to run premade portable cable thru the ceiling and down the walls an have it come out in a external box

Sounds good to me. What are you using for the speakers?

Remember to keep the speaker wires a couple feet away from the mic cables.

If you find a distributor for West Penn (I forgot who I deal with) I think you will find that it's considerably less money than Belden.

What are you running for the speakers? That has to be a CL2 listed cable also. No zip cord, rubber covered, etc.

The truth of the matter is any good quality twisted pair shielded 22awg cable will do perfect for in wall microphone cabling. I personally prefer the foil shelded with drain wire type.

What will matter most is the XLR brand of connectors you use. I use nothing other than Neutrik connector. There are many brands that have copied their design, but none come close to the quality. Not even the old faithful Switchcraft line.

The final piece of the puzzle is how you assembly the connectors. Be sure to put some insulation tubing over the shield/drain wire to keep it from creating ground loops where you don't want them.

As to speaker wire, I have always just used 14 or 12 awg twisted pair non-shielded and again any good quality cable will do the job. If I'm running cable for a constant current system, I'll use 16 or 18 awg twisted pair non-shielded. Yes you can use smaller, but your really taking a chance of major signal drop and blown speakers or a fried amp.

Do not use any type of cable that looks like zip cord. If you do, your just asking for noise to be picked up by it. Save it for you home speakers if you must use it.

I agree with your Neutrik recommendation 100% as well as your assembly.


Which is what Belden 8451 is. Like I said, Belden is top of the line and the difference between it and others is mainly how easy they are to strip.


Well, not just "any good quality cable". One of the most important things to remember that you seem to have overlooked is that any wiring run within walls or ceilings (both microphone and speaker) must be listed to comply with code. This goes for both commercial and in a house. Unless the space is air handling (and I don't think that even enters the equation here) any cable you use must have at least "CM" or "CL2" printed on its jacket. Acceptable substitutons would be CMR, CMX, CL2R, CL2X, CL3, CL3R (and the plenums-CMP, CL2P, CL3P).

-Hal

What you say is true Hal and since it was said already, I didn't think it needed repeating. In hindsight, I should of said it again.

The fact is any cable you use should be rated for the use it is being put too.

Beldin 8451 is great cable, but Alphawire, Gepco and West Penn to name a few also all make great cable and all have the proper specifications.

I have always had less problem stripping West Penn cable than any other brand. The West Penn shielded cable tends to have the shield come off when your strip the outer jacket off, leaving just the twisted pair and drain wire.

In the end it's just personal prefecerance and cost

I'm in the other camp.

I much prefer Switchcraft connectors, although I do use Neutrik for some things, mostly on adapters, and short jumpers.

If the cable is going to take abuse, I always use Switchcraft A series connectors because of the steel shells.

I have had too many Neutrik NC3MX's fail when the tab that the latch engages breaks off. (these are the ones with the slot where the latch engages, and the thin piece of metal gets bent, and subsequently broken, leading to no latch.) I have also had strain reliefs break right off if hit at the wrong angle.

I like Belden, West Penn, and Gepco cable. I also use some Mogami and Canare cable for certain portable applications.
For heavy duty stage cable, it's hard to go wrong with Belden 8412.

tantivy, have you seen the new Neutrik NC*MXX series connectors?
They are much better than the NC*MX.

No, I have not.. I will have to take a look at them.

I have been happily using Switchcraft A and D series connectors since the early 80's, so it will take quite a bit of persuasion to convince me to switch.

I use them in 3, 4, 5 and occasionally 6 pin versions, and one of the things I really like is that the inserts interchange freely between shells, so I can swap them around as needed, without having to stock all possible permutations.

I stopped using Switchcraft because of their cable clamps. It just doesn't cut it any more.

Never had a problem with Neutrik and it was all we used when I was in the lighting industry. I had to deal with some companies equipment that still used Switchcraft and was always fixing them.

The release lever on the panel mount connectors did have a prblem failing, but changing them out was easy without having to change the whole connector

I did sound and lighting throughout high school and college...
I saw some very creative people unscrew the back of the cable connector, remove the connector, and leave the shell in the panel mount!!

I worked for RCA when it was a service company. When not installing crossbar PBX systems, I would work on sound and stage systems. Cannon connectors were all we used and cable from Belden or Alpha was the best. In the 70s, Switchcraft was the "best" XLR and that is all I used. When Neutrik first came out, I was not a fan of the plastic, but I have used their connectors and the newer style is just as good and even better, in some instances, than the Switchcraft. I do use both, depending on availability and the circumstance.

West Penn Wire is very good cable. I use it, almost exclusively, mainly because their distribution facility is local and they are priced very competitively. You-all may not remember "sweep tests" but that is the true test of a cable's worth. I have sweep tested Belden, Alpha and West Penn cables and they test out identical. A good audio technician is aware of ground loops and how to avoid them as well as how to avoid noise and hum by running cables away from potential electrical noise sources. I cringe when I get into some commercial ceilings and find a cable contractor ran audio wires parallel to high voltage electrical wiring, using the same holes in wood as the electrical wiring or, even worse, dragging cable through metal studs in the same space as the electrical cables and not using insulators or hangers. If one segregates the input from the output and keeps all of the audio wiring from laying across fluorescent ballasts and away from long parallel runs in close proximity to power cables, the audio install will work well for a long time.

SwitchCraft was the industry standard before Neutrik came out, but they dropped the ball and Neutrik took over.

West Penn is is the best, quality wise and price wise. Beldin and Alpha are great products, but the price will kill you. West Penn offers the same quality, but at a better price point.

Dealing with electricians that don't have a clue about audio cable is a major pain. By the time they bring someone in that does have a clue, it's too late to re-run the cable.
