Title: Digital snakes and compatibility
Post by: Sean Barry on September 23, 2017, 11:44:29 am
Digital snakes and compatibility

I have a Qu 32 Chrome and am considering the move to a digital snake and stage boxes. ProCo has some offerings for the snake

Musician's Friend SKU J00647 000001000 ProCo 150' cat5 $107

Sweet Water ProCo 150' cat5 $220  Manufacturer part#  C270201-150F
https://www.sweetwater.com/store/detail/EtherShld150
or this
https://www.sweetwater.com/store/detail/Ethercon150    $169
This would be used indoors and out for live mixes of bands.
     I can't see the differences? As far as the pricing? Any input would be greatly appreciated.

I have a TMB Proplex from Mike Pyle that I use with my GLD80 to either a AR2412 or a AB168. I got a 100' model and if I were doing it again I would get 150'.
Initially it was a bit stiff but by the time I got 4 or 5 gigs on it, it loosened up and made for easy over/under coiling.

I would buy it again.

ProPlex is great stuff; we use one from a company called Quabbin that is rugggedized and works well. It's CAT6a, but there are other offerings.

These three cables all seem to be solid core, not stranded. Solid tends to be stiffer than stranded, and is not made for repeated bending. I would buy a stranded one.

Stranded CAT cable has much more reactance, and is generally not recommended unless it is limited to short runs.  Some CAT snake systems have stranded for short runs ("tails") out of the cable reels (where there would be a lot of flexing) while using solid for the long runs.  It varies for type and from manufacturer to manufacturer.

Best solution is fiber for long runs and stranded for patch cables.

I was under the understanding that if the cable was "cat" certified, the actual makeup was irrelevant to performance.

What i have read is the max length for solid is 100m, for stranded it's around 80m. At those lengths I would want fiber anyway.

For 150 feet it's not a problem performance wise.

BTW all references to fiber are a bit uhmmm strange(?), considering we are talking about a QU32... Good luck connecting that.

For some of the boards under discussion, a fiber solution would exceed the cost of the mixer.

I run 200í (60m) of stranded TMBProPlex with my GLDs without issue.  Havenít needed anything longer.

I use this with my QU and either a AB168 or AR2412 or sometimes both, stranded, shielded CAT 5E.

David, you may be correct.  I think that solid CAT cable is inherently less reactive, but if it's certified at a specific category, it should meet the specification.  One discussion I saw recommended 100M maximum for solid and stated 80M was the limit for stranded cable for their particular product.  I have a auditorium that ran 500' runs of CAT5 (100M - 328' was the recommended maximum) and their X32 has been running flawlessly for several years.

Just don't try that with Dante.

Sean, we run Horizon Digital Snakes.  All of our are 250' stranded with 10' removable tails from the reel that they are on.  We also have a couple that care 4 lines per snake run that we use for our Midas Pro plus light send to the stage.  These are also 250' stranded, however they are not on a reel.

We have used these for the past 4 years or so and never had a problem as of yet.
