Conductors use US-Made Cardas Grade One copper Separate solid core Cardas Grade One Copper conductor for the right and left channels Separate OFC copper conductor returns Conductors for each channel are wrapped in a foil shield Hand-soldered XLR-to-XLR cable termination Balanced - XLR audio cables were originally designed for the professional music industry where long cable runs are the norm. They feature three internal conductors plus an outer shield. One conductor carries the positive signal, another the negative signal and the third that grounds to the two circuits on either end together. This design provides superior RFI and EMI shielding and promotes greater signal integrity between electronic components. Noticing that an increasing number of high-end audio manufacturers were featuring balanced connectors on their gear, audio design guru, Jay Victor, set out to create an affordable balanced cable that was superior to anything in it's price class. This Pangea Audio cable uses no-compromise Cardas Grade One Copper, which George Cardas of Cardas Audio developed for his own premium cables. George's copper is mined in Arizona, then shipped to a New England factory where it is very S-L-O-W-L-Y drawn into conductors in a process that includes reduction annealing between steps to further purify and meld the copper into what George calls "the most amazing audio conductor I have ever experienced. It is quite simply the best copper on the planet." Once the cables were finished, Jay sent them to Audio Advisor with a note. It said: "I'm sure you'll love these. They are the best affordable balanced cables I've ever designed. They sound fantastic!" Introducing the Pangea Audio Premier True Balanced Audio Interconnects. If your electronics offer balanced connections, these are the cables you should be using for lower background noise and cleaner sound.
