Pro Co Sound brings multi-tasking to their line of cables with Siamese Twin Cables. They are a unique combination of balanced audio and AC electrical power carried through the same cable assembly with individual shielded lines that prevent EMI/RFI from disturbing the audio signal. Its ingenious construction is extremely useful for providing power to self-powered, full-range, and bi-amplified loudspeaker systems from manufacturers like Turbosound, JBL, EON, EAW, Meyer, Mackie and others.

This design minimizes the number of individual cables flowing from a set of components and aids in reducing cable snarls. Each cable has a fanout of connectors that provide enough reach for the lines to connect to the power and audio ports which may or may not be near each other. The cable ends are color-coded for easy identification and the cable body has a rugged jacket that protects the individual lines inside.

    Comments about Pro Co Sound EC9 Siamese Twin AC & Audio Combo Cable - 25':

    Well they sure are convenient for hooking up self amplified speakers. The price sure reflects the cost. No noise. High quality connectors. Sure wish the website mentioned the gauge of the power cable. It's not labeled. I'm guessing it's somewhere between 16 and 18 gauge. And that can be a problem for some self amplified speakers. It's nice that IEC end is a tad bit longer...but because it's longer it makes coiling and wrapping a velcro tie on this "snake" awkward. It's very thick too... .53 to .57 inches on my calipers...so obviously there is a lot of insulation inside. I wish the cable was flat, rather than this thick and round (making it a trip hazard if you run it across rooms or doors.) And despite all this I love not having to run two cables to my self amplified speakers. Wish I had ordered a '75...but not sure I want to afford one. Recommended accessories...an IEC320 C14 Male to NEMA 5-15R Female pigtail so you can add an extension cord or couple some of these together. For the price a small adapter should be included.

      The quality of these cables are excellent. During a time limited setup these cables save me so much time. I can hook up all of my self powered monitors in one hit.

      Definitely buy these you won't be disappointed.
