The EC3 Siamese Twins audio/power cable from ProCo features one XLR Male to XLR Female audio channel, one XLR Female to XLR Male audio channel, and one Edison to PowerCon Blue power channel.

ProCo's Siamese Twins Cables are designed to provide quick, neat and reliable connections of audio mixers to self-powered full-range and bi-amplified loudspeaker systems, including products from Turbosound, JBL, EON, EAW, Meyer, Mackie and other professional audio manufacturers. ProCo's Siamese Twins Cables combine balanced XLR-type audio lines with specially-shielded high-current AC power cordage in a ruggedly-jacketed composite cable assembly suitable for both fixed and portable professional sound system applications.

The proprietary, multi-conductor, ROHS-compliant cable incorporates a UL-listed, PVC-jacketed, 14-gauge, 3-conductor power cable with a 100% coverage aluminum/mylar shield, with double-shielded, 24 AWG twisted-pair, individually-jacketed audio cables - all within a tough matte-black outer jacket.

Depending upon the configuration required, molded NEMA 5-15P Edison plug connectors, molded NEMA C-13 IEC female inline receptacles, or Neutrik Powercon input/output connectors are combined with the appropriate-gender XLR-type connectors to deliver both 120VAC power and audio to the loudspeaker system, or to daisy-chain from one system to the next if required (for systems providing loop-through audio and power connectors).

Standard Siamese Twins assemblies have a 36" tail for the AC input and 18" tails for the audio connector(s) at the "sending" (mixer) end, and a 12" fanout for both at the "receiving" (loudspeaker system) end. JBL EON cabinets require an additional length of AC cable to reach their power-input connector and are available as a standard product. For easy identification, the audio cables(s) are color-coded with either a white or red jacket and the ends of each composite assembly are color-coded with heat-shrink: red indicating the end to be connected to the AC outlet and mixer and black for the end delivering power and audio signal to the speaker system. Each finished assembly is thoroughly tested to assure both safety and high-definition performance.
