Hello Aaron;
Belden 8451 / 9451 has been the "stanard of the industry" for at least 4 decades.
Both are available with either a black or grey outer jacket.
The only difference between 8451 and 9451 is 9451 has glue applied on the outside of it's foil shield bonding the foil to the outer jacket such that the shield strips off with the jacket in one time and labour saving step when using most decent quality cable strippers.
Of course saying Belden is like saying Kleenex in the sense that it's the old, established, name brand.
You'll find that Carol Columbia, Delco, West Penn and most of the major cable suppliers will have a matching equivalent.
If you're buying a sufficient quantity, even the Belden can be cost effective given the right salesperson.
22 gauge red / black polypropylene twisted pair.
100% foil shield
PVC outer jacket
Used for both mic and line level
Sold in a wide range of put-ups.
Thoughts on making your outer jacket color choice(s):
You may want to pull mic lines in one color and line level in the second color for ease in sorting
Alternately, you may pull in one color with spares in the second color.
I recall doing one job with mics in one color and mic spares in the second color but with
line level in the second color and line level spares in the first color.
Not a big deal for a few runs but quite useful if you're sorting through a few thousand lines in a large project.
Next thought, digital is upon us.
Depending upon what you're up to, some consultants are spec'ing a more digital friendly cable throughout with forethought and staving off obsolesence in mind.
Sorry! I don't have those cable numbers indelibly etched in what's left of my brain but I'm sure Tom, Ivan, Hal or others of our cast of thousands will be along in a post or two.
Toodleoo!
