sound pros are at work and they just won't go easy on cables. Not a problem for our robust SC-MERIDIAN. This cable is specially designed for loudspeakers and meets all relevant technical requirements. Oxygen-free Cu wires ensure a better sound and a higher durability. The FRNC and E30 versions (IEC 228, IEC 332-/1, IEC 332-3 Cat C, IEC 60331, IEC 61034-1/2, IEC 60754-2) are ideally suitable for permanent installation. With its dual screen (Cu braid and AL foil) and a halogen-free, flame-retardant outer jacket pursuant to grade IEC 332.3, the shielded MERIDIAN FG version is suitable for outdoor and indoor installations or ELA technology. For construction reasons this version is not suitable for mobile applications.
