Jim (the Pro):

Thanks for bringing up an excellent point. I too can't tell if the speaker snake #SPK2-20' is shielded or not as it doesn't say anything about this in the product description. Does anyone else here know for sure?

I did inform the Gigcables.com sales guy though, that I intended to use the #SPK2-20' cable to go out from my Tyros keyboard (audio L/R outs) to my PA speaker (audio L/R ins) and he seemed to think the #SPK2-20' speaker snake (2 channel) was the appropriate one to use.The product description reads:

"Using superior quality multi-conductor speaker cable, 13 gauge conductors of bare copper jacketed in configurations of 4, 6 & 8 conductor all in one jacket. The shrink on each channel is color coded for ease of set-up." In addition, the diameter of the snake cable is approx 1/2" thick.

I'll be sure now to make sure (as you recommend) that the cable is fully shielded before ordering it. Thanks for the advice.

Scott
