Each core uses 7 strands of 0.19mm diameter wire giving a 0.20mm² cross-sectional area, and the braided screen comprises 112 strands of 0.12mm wire surrounding all four cores. The cable measures 5.5mm in overall diameter and is supplied on a 100m reel.\u003c\/p\u003e\n\u003cp\u003eDesigned for fixed audio installations in public address systems, background music zones, multi-room audio distribution and low-voltage control applications, the cable balances signal integrity with mechanical durability. The tinned copper conductors resist oxidation in damp environments, the braided screen rejects electromagnetic interference from mains cables and lighting circuits, and the cotton infill between cores and screen maintains core spacing under tension during installation.\u003c\/p\u003e\n\u003cp\u003eThe grey PVC sheath provides abrasion resistance for cable runs clipped to walls, pulled through conduit or routed under floor voids. The 0.20mm² conductor size suits signal-level audio rather than speaker-level runs, keeping resistance low enough for balanced line signals over distances up to 50m without audible loss. The 4-core configuration allows a pair of balanced mono signals or a single stereo balanced signal to be carried on one cable run, reducing conduit congestion and installation time on multi-zone projects.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eGrey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003ctd\u003e0.20mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e4 x 7\/0.19mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e5.5mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked\u003c\/td\u003e\n\u003ctd\u003e4 reels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e100m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScreen\u003c\/td\u003e\n\u003ctd\u003e112\/0.12mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat applications is this cable suited to?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Mercury 4-core is designed for signal-level audio in fixed PA installations, background music systems, multi-room audio distribution and low-voltage control wiring.
