Sommer Cable – – SC-PRIMUS The marathon runner… doesn’t have it easy. He must run and run. In sporting arenas our cables also must put long distances behind themselves. But they neither lie around, nor do they run. The diameter of 2 x 0.50 mm? makes this cable ideal for theatres, public buildings, sporting arenas, etc. Because of the 100 % shielding and a thick outer jacket the SC-PRIMUS is also recommended for installation in discos and night clubs. Neither aggressive nicotine nor strong variations in temperature can affect this cable. Stage technicans swear by it and the touring sound agencies prefer the SC-PRIMUS because of its endurance and ?memory?, making manual winding easy.
